| Conteúdo: | Abstract: Achieving climate neutrality requires renewable, diversified, and efficient energy systems, with sustainable biofuels playing a critical role in decarbonizing transportation. However, major concerns persist regarding indirect land-use change (ILUC). Adding ILUC quantitative emission factors to the carbon intensity of biofuels faced challenges and has been subject to criticism. In response, ILUC risk management approaches are increasingly considered as alternatives. Nevertheless, the most adequate ways to address them are still under debate. Drawing on the effectiveness of existing regulatory measures and insights from scientific literature, this paper proposes five main measures to address ILUC risk. They are focused on increasing the deployment of low ILUC-risk biofuels while preventing high ILUC-risk conditions. Key recommendations include: a) a ‘tiered approach’ for classifying low ILUC risk; b) comprehensive eligibility criteria for low-ILUC risk classification; c) considering zero deforestation criteria as measures to reduce high ILUC risks; d) establishing an intermediate risk category between low and high; and e) measures to address incomplete knowledge, such as phased implementation over time. By focusing on overcoming current limitations, this proposal aims to contribute to the deployment of sustainable biofuels on a sufficient scale to promote the energy transition while minimizing high ILUC risks. |

| Conteúdo: | Abstract: Soil salinization is a critical global issue threatening agricultural productivity and significantly reducing the availability of arable land. Effective mitigation and recovery strategies are vital for sustaining food production, especially in the context of climate change. Halophytic plants, such as Atriplex nummularia, have shown potential for remediating saline soils, though their large-scale application remains limited. An alternative approach involves leveraging microorganisms adapted to saline environments to enhance plant stress tolerance. In this study, we investigated the microbiome of A. nummularia under saline and non-saline irrigation conditions to identify extremophilic microorganisms that promote salt stress tolerance. Through 16S rRNA analysis, we identified members of the genus Haladaptatus exclusively in the rhizosphere of salt-irrigated plants. These microorganisms were isolated and inoculated into maize crop systems to evaluate their ability to confer salt tolerance. Our results demonstrate that Haladaptatus strains significantly enhance salinity tolerance in maize, with a marked increase in the relative abundance of archaeal 16S rRNA in soils as NaCl irrigation levels rise. This study provides the first evidence that Haladaptatus, an archaeon isolated from the rhizosphere of a halophyte, can significantly enhance salt tolerance in an agriculturally important crop. These findings suggest a promising biotechnological application for improving crop resilience in saline environments, offering a sustainable strategy for addressing soil salinization and securing food production in the context of global climate challenges. |

| Conteúdo: | Abstract: Determining the optimal combination and proportion of species remains a key challenge for balancing and optimizing nutrient recycling in polyculture systems. The aim of this study was to evaluate diet, food-source utilization, and trophic interactions of tambaqui (Colossoma macropomum) reared in monoculture or in polyculture with curimba (Prochilodus lineatus), using carbon and nitrogen stable isotopes and Ecopath modeling. Three production systems were compared: tambaqui monoculture (0.25 fish m−2) (T), and tambaqui–curimba polycultures with high (0.25 fish m−2) (TC) and low (0.08 fish m−2) tambaqui final densities (TLC). Across all treatments, tambaqui production was primarily supported by feed (<85%), while curimba growth relied on live or dead zooplankton. However, in TLC, the contribution of zooplankton to the curimba diet significantly decreased (from 68% in TC to 44% in TLC), while formulated feed increased (from 5% in TC to 24% in TLC), resulting in an overlap of isotopic niches between both fish species. Polyculture promoted higher ecotrophic efficiency of both feed and zooplankton, as well as higher system omnivory and Finn\\\'s cycling index. Polyculture may promote more efficient utilization of natural food resources in the ponds and lead to higher yields compared to monoculture. A high tambaqui density in polyculture (0.25 tambaqui m−2 with 0.30 curimba m−2) minimizes competition with curimba for formulated feed, while enhancing nutrient recovery and overall system efficiency. |

| Conteúdo: | Abstract: Research background: Ultraviolet-B (UV-B) radiation induces oxidative stress through the generation of reactive oxygen species, affecting organisms across all domains of life. While UV-stress responses have been extensively studied in the ascomycete yeast Saccharomyces cerevisiae and animal systems, little is known about the molecular mechanisms underlying UV tolerance in basidiomycete, UV-resistant yeasts. Carotenoid-producing yeasts of the genus Sporobolomyces represent an attractive model to investigate whether conserved oxidative stress pathways, including bZip transcription factor signalling analogous to the vertebrate Nrf2 pathway, contribute to UV tolerance. Experimental approach: The UV-tolerant yeast Sporobolomyces sp. LEV-2 was exposed to UV-B irradiation for up to 24 hours. Quantitative multidimensional protein identification technology (MudPIT) mass spectrometry using tandem mass tag (TMT) labelling was applied to identify and quantify protein expression changes over time. Identified proteins were functionally annotated using InterProScan, KEGG tools and literature-based curation, and proteomic data were integrated with measurements of antioxidant activity and cell viability. Results and conclusions: A total of 751 proteins were identified, including 105 stress-response proteins. UV-B exposure induced a coordinated oxidative stress response involving conserved signalling pathways (bZip, MAPK, FoxO, Ras and calcium signalling), antioxidant enzymes, heat-shock proteins and DNA repair factors. A bZip protein (LEV-2_XP_007274754.1) displayed Nrf2/Yap1-like behaviour, suggesting a central regulatory role in UV-induced stress signalling. A four-step model of UV adaptation was proposed, encompassing signalling, metabolic stress, antioxidant-driven adaptation and establishment of a stress-resistant state. These responses closely parallel UV- and oxidant-induced stress responses described in other fungi and in animal cells. Novelty and scientific contribution: This study provides the first proteome-level analysis of UV-B stress adaptation in a Sporobolomyces yeast and demonstrate that UV tolerance relies on ancient, evolutionarily conserved oxidative stress mechanisms shared across eukaryotes, rather than yeast-specific pathways. |

| Conteúdo: | Abstract: The rapid global expansion of aquaculture demands innovative strategies to enhance productivity while safeguarding fish health under intensive rearing conditions. This study investigated the effects of dietary supplementation with an alcoholic extract of Artemisia annua (ae-Aa) on growth performance, physiological stress, immune responses, oxidative status, and tissue morphology of Nile tilapia (Oreochromis niloticus) cultured in a high-density net-cage system. A 2 × 2 factorial was applied, including two dietary treatments (supplemented, S; non-supplemented, NS) and two feeding periods (30 and 60 days), yielding four experimental groups (S-30, NS-30, S-60, NS-60). Compared with their respective controls, ae-Aa supplementation significantly enhanced survival and growth at both time points (P < 0.05), evidenced by greater weight gain and protein efficiency ratio and a reduced feed conversion ratio. Supplemented fish also showed increased intestinal villus thickness and hepatosomatic index (P < 0.05). Plasma cortisol concentrations were significantly lower in supplemented groups at both sampling periods (P < 0.05). Moreover, ae-Aa supplementation stimulated innate immune responses, reflected by elevated lysozyme activity, plasma protein level, and leukocyte respiratory burst (P < 0.05). Oxidative stress was notably mitigated in supplemented fish (P < 0.05), with reduced lipid peroxidation, enhanced catalase, glutathione peroxidase, and glutathione S-transferase activities, and decreased DNA damage observed at 60 days. In conclusion, dietary ae-Aa supplementation improved growth performance, immune competence, antioxidant capacity, and tissue integrity while alleviating physiological stress in Nile tilapia, supporting its application as a sustainable plant-based feed additive for intensive aquaculture systems. |

| Conteúdo: | Abstract: This study applied a flavoromic approach to identify the most suitable combination of training system (trellis, lyre, and espalier) and rootstock (IAC 572 and IAC 766) for grape cultivation aimed at juice production. Grape juices were evaluated for physicochemical properties, antioxidant activity, phenolic profile (LC-DAD-QToF-MS), volatile composition (HS-SPME-GC/qMS), odor-active compounds (OSME-GC-O), and sensory attributes. Juices produced from vines grafted onto IAC 572 showed higher anthocyanins contents, resulting in greater color intensity and antioxidant activity. The trellis & times; IAC 572 combination yielded the highest concentrations of ethyl esters with intense fruity aroma. Foxy notes were more pronounced in juices from trellis and espalier systems combined with IAC 572, which correlated with higher furaneol levels. Therefore, flavoromics demonstrated that the enhanced vegetative growth and regulated solar incidence provided by IAC 572, particularly when combined with trellis or espalier systems, favor the biosynthesis of key metabolites that drive grape juice quality. |

| Conteúdo: | Abstract: This study evaluated the effects of two doses of 3-nitrooxypropanol (3-NOP) on methane (CH4) emissions, performance, dry matter (DM) intake, apparent digestibility, rumen microbiome and metabolomic profile of Nellore cattle fed a high-concentrate finishing finishing diet. Seventy-five 20-month-old Nellore bulls, 361.6 ± 30.08 kg body weight (BW), were individually housed with ad libitum access to feed and water. Animals were distributed in a completely randomized study design, with three treatments and 25 animals per treatment, which were: 1) CON, control (basal diet + mineral premix without 3-NOP), 2) 3-NOP65 (Basal diet + mineral premix + 65 mg 3-NOP/kg of DM), 3) 3-NOP85 (Basal diet + mineral premix + 85 mg 3-NOP/kg of DM). The 115-d trial included a 3-wk adaptation period with increasing dietary concentrate levels from 50% to 88%. Enteric CH4 emissions were measured using the sulfur hexafluoride (SF6) tracer gas technique. Supplementation with 3-NOP had no detrimental effect on final BW (P = 0.89) and average daily gain (ADG; P = 0.94), but DM intake increased linearly with 3-NOP inclusion (P = 0.05). Methane emissions (g/d) were reduced by 13.2% and 26.7% in the 3-NOP65 and 3-NOP85 groups, respectively (P < 0.05), without adverse effects on animal health. Rumen microbiome analysis revealed a quadratic response in the relative abundance of the phylum Euryarchaeota (P = 0.01). Metabolomic analysis indicated significant changes in amino acid and energy metabolism, with proline, arginine, and threonine identified as key discriminant metabolites (VIP > 1) in the 3-NOP85 group. These findings demonstrate that 3-NOP supplementation effectively reduces CH4 emissions in a dose-dependent manner while maintaining animal performance and health. |

| Conteúdo: | Abstract: Background: Climate change has driven the expansion of viticulture in high-altitude tropical regions. The dynamics of grape ripening and its metabolic profile are influenced by climatic conditions. This study aimed to identify the optimal harvest period for Cabernet Sauvignon grapes cultivated in an emerging Brazilian high-altitude region using a targeted metabolomics approach. Phenolic composition, antioxidant activity, and physicochemical parameters were monitored over a 10-week ripening period from veraison. Results: Grapes harvested between weeks 6 and 9 exhibited physicochemical attributes favorable to winemaking, including pH (3.50-3.63), soluble solids (21.33-21.43 degrees Brix), skin hardness (4.52-6.23 kg m s-2), berry firmness (157.83-177.62 kg m s-2), and color. Grapes from 6 and 7 weeks presented the highest levels of anthocyanins (delphinidin-3-glucoside, cyanidin-3-glucoside, petunidin-3-glucoside, malvidin-3-glucoside, among others), flavan-3-ols (epicatechin and epicatechin gallate), and flavonols (myricetin-3-O-glucuronide, myricetin-3-O-glucoside, and kaempferol-3-O-glucoside). These metabolites contribute to color enhancement and stability through copigmentation, accounting for the elevated antioxidant activity observed at these stages. Conclusion: Therefore, weeks 6 and 7 represent the ideal harvest period for Cabernet Sauvignon grapes in this high-altitude tropical region, combining favorable physicochemical maturity with maximal phenolic content and antioxidant potential. |

| Conteúdo: | Abstract: Backgground: We report the bioassay-guided isolation and identification of phytotoxic compounds from an extract of the fungus Xylaria grammica (Ascomycota), isolated from leaf lesions of seedlings of Handroanthus serratifolius (Bignoniaceae), from the Atlantic Rain Forest in Brazil. From the fungal crude extract, grammicin (1) and xylaric acid methyl ester (2) were purified and identified using one- and two-dimensional nuclear magnetic resonance and high-resolution mass spectrometry analysis. Results: Grammicin exhibited activity against Lactuca sativa (lettuce) and Agrostis stolonifera (bentgrass) at 1 mg mL−1, resulting in 100% inhibition of seed germination. Compound 2 had no activity against L. sativa but showed moderate activity against A. stolonifera, inhibiting seed germination at 1 mg mL−1. Against Lemna paucicostata (duckweed), grammicin inhibited growth by 50% (IC50) at 87.7 μM, while compound 2 had no activity. Neither compound had antifungal activity against the plant pathogen Colletotrichum fragariae. Grammicin is structurally similar to the natural compound patulin, which is reported to be phytotoxic by inhibition of photosystem II (PSII). Molecular modeling of the interaction of grammicin with the D1 protein of PSII predicts it to be a strong PSII inhibitor; however, in vivo testing indicated that it is a very weak PSII inhibitor. Patulin was highly cytotoxic to mammalian cells whereas grammicin was not cytotoxic. Conclusions: This is the first report unveiling the phytotoxicity of grammicin, which could serve as a scaffold for developing more potent herbicides with improved physicochemical properties and without any potential for cytotoxicity. |

| Conteúdo: | Abstract: Brazil is at the forefront of both forest conservation and global food security, and thus, understanding the dynamics of soil organic carbon (SOC) is crucial for both. We developed a spatiotemporal model to predict national-scale changes in SOC stocks to 1 meter depth, over the last 40 years. We utilized a combination of static and dynamic environmental covariates along with more than 50,000 observation points to calibrate a machine learning model. The models achieved satisfactory accuracy, with R2 values ranging from 0.48 to 0.88 in cross-validation and from 0.18 to 0.31 in external validation. Our findings revealed a significant reduction in SOC stocks in the North rainforest region (Amazon biome), with the largest increase in the Northeast drylands (Caatinga biome). Specifically, net SOC losses occurred in Amazon (-0.020 Pg yr-1), Atlantic Forest (-0.002 Pg yr-1), and Pampa (-0.0004 Pg yr-1). Net gains were found in the Cerrado (0.016 Pg yr-1), Caatinga (0.007 Pg yr-1), and Pantanal (0.001 Pg yr-1). Over the past 40 years, we estimated an absolute gain of 0.80 Pg C in Brazil. Land-use change from forests to anthropogenic uses was the primary driver of SOC stock loss, whereas conversion from pastures to croplands generally led to SOC gains. The efforts to combat climate change in Brazil require reducing deforestation and promoting sustainable agricultural intensification. |

| Conteúdo: | Abstract: Background: The cattle tick Rhipicephalus microplus is a major constraint to livestock production in tropical regions, causing substantial economic losses and driving intensive acaricide use. Despite its importance, the role of pasture composition in shaping off-host tick populations remains poorly understood. This study evaluated whether forage grass species create distinct microenvironments that influence the seasonal abundance and persistence of R. microplus larvae in a tropical region. Results: Larval abundance was higher overall in the dry season than in the rainy season, with a significant interaction between grass and season. Grass cultivars differed markedly during the dry season. Two Megathyrsus maximus cultivars supported the highest larval densities and the longest recovery windows, whereas two Urochloa sp. cultivars showed the lowest larval densities. Differences in larval abundance were not significant during the rainy season across grasses (P = 0.13). Minimum temperature and minimum relative humidity were the most influential microclimatic predictors of larval abundance. Conclusion: The interaction between forage species and seasonal climate influences R. microplus population dynamics, particularly under dry conditions. Although pasture composition alone is unlikely to determine infestation levels under grazing conditions, and larval abundance in pasture does not necessarily translate directly into infestation levels on cattle, certain grass cultivars may contribute to microenvironments less favorable for tick survival. These findings highlight the potential of forage species to influence off-host tick dynamics, acting as a complementary component of the integrated R. microplus management. |

| Conteúdo: | Abstract: An ex-ante life cycle assessment at technology readiness level 6 (TRL 6) was applied to compare the environmental performance of three lignin-based fungicide nanoformulations (PTZ-AKL, TBZ-AKL, PTZ-AMKL) against commercial analogs, focusing on sustainable corn and soybean production. Pilot-scale analysis identified two main hotspots: the chemical modification stage, responsible for ∼85% of ecotoxicity due to reagents like acetic anhydride, and electricity use, driving ∼67.4% of climate change impacts. However, the cradle-to-grave scenario demonstrated that substituting conventional fungicides with the nanoformulations yields substantial environmental benefits, particularly in soybean cultivation, where fewer applications reduced ecotoxicity by over 60%. Prospective optimizations—including solvent recovery and renewable energy adoption—further mitigate production impacts, reinforcing the ecological potential of these nanoformulations as practical substitutes for conventional agrochemicals. |

| Conteúdo: | Abstract: Postharvest losses remain a major challenge in fruit production systems, affecting both climacteric fruits, such as papaya, and non-climacteric fruits, such as orange. Ultraviolet-C (UV-C) radiation has emerged as a sustainable alternative to chemical fungicides; however, its effectiveness depends on the applied dose and radiation delivery mode. This study investigated the comparative effects of continuous and frequency-modulated UV-C radiation on postharvest disease control and fruit quality on papaya and orange. Two independent experiments were conducted. Experiment 1 evaluated the influence of modulation frequencies (0, 15, 30, and 45 Hz) on disease progression, while Experiment 2 combined the most effective frequencies with different exposure times to define optimal treatment conditions. In papaya, UV-C modulation at 30 Hz/20 s (0.44 kJ m⁻²) provided effective control of anthracnose (67% reduction in incidence), while minimizing photothermal damage, with no visible epidermal injuries. In orange, continuous UV-C radiation (0 Hz) applied for 30 s (1.99 kJ m⁻²), completely suppressed sour rot development (100%) without visible peel injury. Therefore, the selection of the UV-C radiation application mode is species-specific. Notably, modulation of UV-C irradiation has demonstrated enhanced efficiency in postharvest disease control while reducing epidermal burn. Additionally, the treatments stimulated defense responses, as evidenced by increased activities of phenylalanine ammonia-lyase, polyphenoloxidase, peroxidase, and catalase. Physicochemical analyses confirmed the maintenance of firmness, acidity, and color stability, indicating the preservation of postharvest quality in both fruits. Overall, modulated UV-C radiation represents a promising non-chemical postharvest technology, enabling efficient disease control while maintaining fruit quality. Menos |

| Conteúdo: | Abstract: Aviation fuel remains the main cost and environmental burden in air transport. This study presents a well-to-wake life cycle assessment (LCA) of canola-based Sustainable Aviation Fuel (SAF) under tropical conditions, based on primary data from Brazilian producers. The analysis encompasses agricultural, pre-processing, and conversion stages via the hydroprocessed esters and fatty acids (HEFA) pathway, revealing the potential of second-crop canola for low-carbon aviation. The study integrates process modeling, renewable hydrogen, and land-use efficiency to capture drivers across stages. The ReCiPe method was applied to 1 MJ of biokerosene as the functional unit. Agriculture dominates GHG emissions (34.2 g CO2 eq. MJ−1), driven primarily by fertilizer production and soil N2O emissions, while the HEFA phase contributes 12.8 g CO2 eq. MJ−1. Substituting fossil hydrogen with photovoltaic- and wind-based hydrogen for in HEFA upgrading reduces emissions by 92 to 96.6%, resulting in up to 19.6% lower total life-cycle emissions. Compared to Jet-A1, SAF decreases fossil depletion by 59% and achieves climate benefits; however, it entails higher burdens in selected non-climate impact categories. Freshwater and marine eutrophication reach approximately 0.01 g P eq. MJ−1 and 0.7 g N eq. MJ−1, respectively, while human toxicity is above 1 g 1,4-DB eq. MJ−1, with the agricultural stage accounting for over 90% of these impacts, particularly fertilizer production and use. Land occupation (0.074 m2 yr MJ−1) is optimized through canola soybean rotation, mitigating deforestation risks. The findings demonstrate canola’s strategic role in Brazil’s decarbonization policies, highlighting the need for improved fertilizer management and renewable hydrogen integration to advance SAF. |

| Conteúdo: | Abstract: Arbuscular mycorrhizal fungi (AMF) represent a key biological strategy for enhancing agricultural resilience under extreme climatic events such as drought. However, how AMF interact with drought-tolerant plant genotypes to sustain performance under water limitation remains poorly understood. Here, we used high-throughput DNA sequencing to investigate AMF communities associated with drought-tolerant (BAT477 and SEA5) and drought-susceptible (IAC-Milênio and IAC-80SH) common bean genotypes, integrating taxonomic, structural, and functional perspectives under contrasting water regimes. We hypothesized that drought tolerance is not simply linked to AMF presence, but rather to the ability of host genotypes to structure and stabilize their mycorrhizal communities under stress. Our results reveal genotype-specific responses to drought, with distinct community restructuring dynamics observed across individual genotypes. Drought-tolerant genotypes maintained or increased AMF relative abundance, diversity, and functional integrity under drought, whereas susceptible genotypes displayed opposing changes in the community\\\'s structure. Although most genotypes displayed high dissimilarity in AMF community structure between control and drought conditions, tolerant genotypes reorganized their communities through increase in the relative abundance of key ASVs, whereas susceptible genotypes experienced substantial reductions in abundance, diversity, and specialist ASVs. Niche occupancy and functional guild analyses further showed that AMF communities in tolerant genotypes were dominated by specialist and symbiotrophic ASVs, whereas susceptible genotypes shifted toward rare and functionally reduced assemblages. At the plant level, AMF community stability was positively associated with root biomass and negatively associated with foliar nutrient, indicating a tight coupling between mycorrhizal community structure, host nutritional status, and growth. Collectively, our findings indicate that drought tolerance in common bean emerges, at least in part, from a cooperative host–microbiome strategy in which the host actively regulates the structure and functional stability of AMF communities under water stress. These results advance our understanding of plant-mycorrhizal interactions in drought adaptation and highlight the potential of integrating mycorrhizal functionality into plant breeding strategies aimed at developing climate-resilient crops. |

| Conteúdo: | Abstract: Amblyomma sculptum is the main vector of Rickettsia rickettsii, the etiological agent of Brazilian spotted fever (BSF), a relevant zoonosis due to the increasing number of human deaths. This study evaluated the efficacy of seven commercial products against A. sculptum larvae, with comparative assays also conducted for Rhipicephalus microplus. Formulations were first evaluated using the larval packet test (LPT), then in semi-field trials in Urochloa (Syn. Brachiaria) brizantha, Panicum maximum, and Cynodon spp. forages, and last in an ecotoxicity assay. In the LPT, LC99 values for the products ranged from 0.0024 to 1.39 mg/mL for A. sculptum, and from 0.0093 to 0.56 mg/mL for R. microplus. The efficacy rates against A. sculptum in Urochloa were 93.1 %, 96.4 %, and 97.0 % for lambda-cyhalothrin, thiamethoxam + lambda-cyhalothrin, and abamectin, respectively. For R. microplus, the efficacies were 80.8 %, 95.1 % and 75.2 % for lambda-cyhalothrin, 89.8 %, 97.9 % and 88.8 % for thiamethoxam + lambda-cyhalothrin, and 40.7 %, 56.0 % and 6.2 % for abamectin, in Urochloa, Cynodon, and Panicum, respectively. Climatic conditions were similar across forages, favouring larval survival, except for the effect of rainfall on A. sculptum. In ecotoxicity assays, lambda-cyhalothrin and thiamethoxam + lambda-cyhalothrin had mild effects on recovery, growth and fertility of Caenorhabditis elegans. Thiamethoxam +lambda-cyhalothrin offers short-term larval control under semi-field conditions and is another option for managing A. sculptum in areas at risk of BSF. Further studies are required to assess efficacy against nymphs and adult ticks, environmental impacts, effects on non-target organisms, and residual activity, to ensure the sustainable use of these acaricides. |

| Conteúdo: | Abstract: Understanding the growth dynamics and climatic sensitivity of Bertholletia excelsa (Brazil nut tree) is essential for assessing tropical forest resilience and recent hydroclimatic variability in Amazonia. Despite its ecological and socioeconomic importance, dendrochronological information for this species remains limited, particularly regarding the mechanisms linking large-scale climate forcing to local growth responses. In this study, we developed and evaluated growth-ring chronologies from adult B. excelsa trees in native Amazonian forests to assess growth coherence and the strength of climatic signals. Ring widths were cross-dated using COFECHA, and chronology quality statistics—effective interseries correlation (rbar.eff), expressed population signal (EPS), signal-to-noise ratio (SNR), and first-order autocorrelation (AC)—were calculated using the dplR package in R. The master chronology exhibited strong internal coherence (rbar.eff = 0.38–0.46) and a robust common signal (EPS > 0.85; SNR > 5.0), confirming reliable cross-dating and representativeness at the population level. Moderate autocorrelation values indicated physiological persistence associated with hydrological memory. Radial growth was strongly controlled by hydroclimatic variability, with precipitation emerging as the primary limiting factor and temperature acting mainly as a stressor. Growth responses were particularly sensitive during the transition from the dry to the rainy season, when cambial reactivation and earlywood formation occur. Large-scale oceanic forcing associated with ENSO and Tropical Atlantic variability influenced growth indirectly by modulating local precipitation regimes and dry-season severity, resulting in lagged growth responses following drought events. These findings demonstrate that B. excelsa integrates climatic information across the full hydrological cycle and functions as a sensitive bioindicator of recent climate variability, providing valuable insights into forest vulnerability and resilience under ongoing climate change. |

| Conteúdo: | Resumo: A castanheira-da-amazônia (Bertholletia excelsa Bonpl.) é uma espécie de elevada relevância ecológica e socioeconômica, cuja ocorrência está associada a solos altamente intemperizados e de baixa fertilidade natural. Compreender a organização espacial dos atributos do solo em áreas naturais com ocorrência da espécie é fundamental para elucidar os controles edáficos sobre o desempenho ecofisiológico da espécie. Neste estudo, objetivou-se caracterizar a estrutura espacial dos atributos químicos e físicos do solo em cinco áreas naturais com ocorrência de castanheira-da-amazônia no estado do Amazonas, por meio de modelagem geoestatística e interpolação espacial por krigagem. Foram analisados atributos integradores da fertilidade, incluindo alumínio (Al3+), acidez potencial (H+Al), capacidade de troca catiônica (CTC a pH 7), saturação por bases (V%), saturação por alumínio (m%), carbono, textura e densidade do solo. A dependência espacial foi avaliada por meio de variogramas e classificada com base no índice de dependência espacial (IDE). Observou-se predominância de dependência moderada na maioria das áreas, maior proporção de dependência forte em Anori e predominância de dependência fraca em Ceará/Manicoré, indicando diferentes níveis de organização espacial da fertilidade. Os mapas de krigagem evidenciaram a formação de mosaicos edáficos que condicionam a distribuição de água e nutrientes em escala intraárea. Esses padrões sugerem que a variabilidade espacial do solo influencia diretamente a disponibilidade de recursos, com implicações para o funcionamento ecofisiológico, o crescimento e a produtividade da espécie. Conclui-se que a heterogeneidade edáfica constitui componente funcional dos ecossistemas amazônicos, devendo ser considerada em estudos ecológicos e estratégias de manejo sustentável da castanheira. |

| Conteúdo: | Abstract: A castanheira-da-amazônia (Bertholletia excelsa Bonp.) é uma espécie-chave nos ecossistemas florestais tropicais, cuja produtividade e distribuição estão associadas às condições edáficas. Este estudo teve como objetivo caracterizar a fertilidade do solo e analisar a estrutura espacial de atributos químicos e físicos em área de ocorrência natural da espécie no município de Itaúba, Mato Grosso, Amazônia meridional. Foram coletadas amostras de solo em 60 pontos distribuídos em malha sistemática, com determinação de atributos químicos (Al³⁺, H+Al, Ca, Mg, K, P, Na, Fe, Mn e Cu), carbono do solo, fração argilosa e densidade do solo. A variabilidade espacial foi avaliada por meio de análise geoestatística, incluindo modelagem variográfica e interpolação por krigagem ordinária. Os resultados indicaram solos fortemente ácidos, com baixa saturação por bases e elevada saturação por alumínio, características típicas de ambientes altamente intemperizados. A maioria dos atributos apresentou dependência espacial fraca, evidenciando elevada micro-heterogeneidade em escala local, enquanto a fração argilosa e o cobre apresentaram dependência espacial moderada, indicando maior organização estrutural. A análise de tendência espacial revelou gradientes de baixa intensidade para atributos relacionados à acidez do solo. Os mapas de krigagem evidenciaram a formação de mosaicos edáficos intra-área, com variação espacial na disponibilidade de água e nutrientes. De forma integrada, os resultados demonstram que a organização espacial da fertilidade do solo constitui fator determinante para o funcionamento ecológico de populações naturais de Bertholletia excelsa, destacando a importância de abordagens espaciais para estudos edáficos e para o planejamento de estratégias de manejo e conservação na Amazônia meridional. |

| Conteúdo: | Resumo: Este estudo teve como objetivo caracterizar os atributos físicos e químicos de solos sob dois castanhais nativos localizados na Floresta Nacional do Tapajós (Pará) e na Reserva Extrativista Rio Cajari (Amapá), de modo a fornecer subsídios para o manejo sustentável da castanheira-da-amazônia (Bertholletia excelsa). Foram coletadas amostras de solo na profundidade de 0–20 cm, em um grid sistemático de 60 pontos em cada área, e analisados parâmetros granulométricos, físico-hídricos e químicos conforme metodologias da Embrapa (2011). Os resultados mostraram contrastes marcantes entre os dois ambientes. O solo do Castanhal I apresentou textura argilosa, maiores teores de carbono e nitrogênio, maior microporosidade e porosidade total, condições favoráveis à retenção de água e nutrientes, mas também elevada acidez e alta saturação por alumínio, configurando limitações químicas relevantes. No Castanhal II, a textura arenosa, a predominância de macroporos e os menores teores de matéria orgânica e nutrientes apontaram limitações físicas e de fertilidade, ainda que com menor acidez e baixa saturação por alumínio. A variabilidade espacial dos atributos edáficos em ambas as áreas destacou a importância de análises locais detalhadas, que considerem o mosaico de condições internas a cada castanhal. Os resultados evidenciam que a castanheira apresenta tolerância a ambientes contrastantes, mas enfrenta restrições específicas, reforçando a necessidade de estratégias de manejo diferenciadas. Este trabalho contribui para a compreensão das relações solo–espécie na Amazônia Oriental e orienta práticas de manejo e conservação voltadas à sustentabilidade dos castanhais. |

| Conteúdo: | Resumo: A fertilidade do solo em florestas tropicais é caracterizada por elevada heterogeneidade espacial, resultante da interação entre processos pedogenéticos, hidrológicos e biogeoquímicos. Em castanhais naturais da Amazônia, compreender a organização espacial dos atributos do solo é fundamental para interpretar os mecanismos que regulam a disponibilidade de recursos para Bertholletia excelsa. Este estudo teve como objetivo analisar a variabilidade espacial de atributos físicos e químicos do solo em uma área de castanheira-da-amazônia localizada no estado de Roraima, utilizando ferramentas geoestatísticas. Foram analisados atributos relacionados à fertilidade e à estrutura do solo, incluindo fração argila, carbono, alumínio trocável, acidez potencial, capacidade de troca catiônica, fósforo disponível e densidade do solo. A estrutura espacial foi avaliada por meio da construção de variogramas experimentais e ajuste de modelos teóricos, sendo posteriormente aplicada a krigagem ordinária para interpolação espacial dos atributos selecionados. Os resultados indicaram que a maioria das variáveis apresentou dependência espacial detectável, com predominância do modelo variográfico esférico. A fração argila, o carbono do solo e o alumínio trocável apresentaram forte dependência espacial, enquanto fósforo disponível, densidade do solo e capacidade de troca catiônica exibiram dependência moderada. A interpolação espacial revelou a presença de mosaicos edáficos intra-área, evidenciando gradientes espaciais de fertilidade e textura do solo. Esses padrões sugerem que a disponibilidade de água e nutrientes pode variar significativamente em pequenas escalas espaciais, influenciando o funcionamento ecofisiológico da castanheira. A integração entre análises geoestatísticas e interpretação pedogeoquímica permitiu evidenciar como gradientes edáficos podem estruturar a disponibilidade de recursos no sistema solo-planta. Os resultados contribuem para ampliar a compreensão da dinâmica edáfica em castanhais amazônicos e fornecem subsídios científicos para estratégias de manejo sustentável e conservação de sistemas extrativistas baseados na castanheira-da-amazônia. |

| Conteúdo: | Abstract: Training system and rootstock influence grape quality by regulating vegetative vigor, canopy structure, and metabolite biosynthesis, which may impact the juice shelf life. This study applied a targeted metabolomics approach to evaluate how combinations of training system and rootstock affect the physicochemical, phenolic, antioxidant, and volatile profiles of ‘BRS Magna’ grape juices during 24 months of storage. The metabolomic evaluation was conducted using LC-DAD-qTOF-MS for phenolic profiling, HS-SPME-GC-qMS for volatile characterization, and spectrophotometric assays to determine antioxidant activity and color. All juices met regulatory standards of total acidity (61.77–75.31 mEq L−1), volatile acidity (1.13 and 1.75 mEq L−1) and soluble solids (16.3–19.2 °Brix) during 24 months of storage. Total acidity and phenolic compounds, especially anthocyanins, declined during storage, causing orange color shifts and reduced antioxidant activity. These changes were observed for all combinations of training systems and rootstocks. However, the espalier × IAC 572 combination resulted in juices with the highest phenolic content, which contributed to greater antioxidant activity and enhanced color stability even after 24 months of storage. These juices also contained higher levels of esters and furaneol, enhancing pleasant aromas compared to other combinations. The enhanced performance of this combination was attributed to greater sunlight exposure and vegetative vigor, which stimulate the biosynthesis of metabolites linked to stability. This study demonstrated that the storage potential of grape juices can be optimized through agronomic practices that promote the accumulation of quality- and stability-related metabolites. |

| Conteúdo: | Abstract: The expansion of grain production into former pasture areas in Brazil, one of the biggest grain producers’ countries worldwide, has intensified concerns regarding the residual effects of auxinic herbicides historically used for broadleaf weed control. Among these, picloram (4-amino-3,5,6-trichloropicolinic acid) stands out due to its high persistence and mobility in soil, posing a significant risk to sensitive rotational crops. This review discusses the implications of picloram use in pasture systems and its impact on the incorporation of these areas into soybean-based grain production systems. Owing to its low adsorption coefficient and moderate water solubility, picloram exhibits considerable leaching potential and a prolonged half-life, which may extend beyond 300 days depending on soil and climatic conditions. Its primary dissipation pathway occurs via aerobic microbial degradation, and reduced oxygen availability at deeper soil layers can further prolong its residual activity. Soybean, dry beans, and tomato are highly sensitive to picloram residues, with phytotoxic symptoms including epinasty, leaf deformation, root thickening, growth inhibition, and yield reduction. Even low soil concentrations have been associated with significant grain yield losses, characterizing a carryover effect that may persist for more than two growing seasons. Additionally, the herbicide may remain biologically active after passage through livestock digestive systems, raising concerns regarding manure contamination. Detection strategies include herbicide application history analysis, bioassays using sensitive indicator species, and chromatographic techniques, each presenting methodological limitation when used individually. Mitigation approaches include rational herbicide use, avoidance of picloram in areas intended for future grain production, phytoremediation strategies, and crop rotation with more tolerant species such as corn and sorghum. Given the projected increase in soybean cultivation in areas formerly under pasture, understanding picloram behavior in soil and its agronomic implications is essential to ensure sustainable land–use transition and prevent yield losses associated with herbicide carryover. |

| Conteúdo: | Abstract: Mineral fertilizers account for 18% of Brazil’s agricultural greenhouse gas (GHG) emissions, as reported in the Fourth National Inventory. Initial estimates relied on IPCC Tier I factors, but recent methodologies have advanced toward Tier II and III approaches, incorporating fertilizer type and regional conditions. This study aimed to refine direct N₂O emission estimates by proposing specific emission factors (EFs) for organic, mineral, and combined fertilizers across sugarcane, grain, and pasture systems. These factors considered environmental conditions, agricultural practices, and excreta inputs to improve national representativeness. A systematic review of 56 articles from Web of Science, Scopus, and SciELO yielded 325 trials. Variables analyzed included climate, biome, soil type, irrigation, management, nitrogen sources and rates, pH, texture, and soil carbon, nitrogen, and organic matter. Statistical analyses included boxplots, Kruskal–Wallis tests, and meta-analysis with bootstrapping, all performed in R. Higher N₂O emission factors were generally observed in pasture systems under Cwa climatic conditions, in grain systems under subtropical climates (Cfb and Cfa), and in sugarcane systems under tropical and subtropical climates (Am and Cfa), with elevated values frequently observed in the Cerrado and Atlantic Forest biomes. Weighted EFs ranged from 0.14 to 1.63%, while national average EFs were 0.66 for sugarcane, 0.69 for grains, and 0.64 for pastures, all within the uncertainty range of IPCC default values. These results demonstrate the potential of Tier II factors to improve N₂O emission estimates in Brazil, while highlighting important limitations related to data availability, methodological heterogeneity, and uneven geographic coverage. Continued efforts to expand regionally representative datasets and advance toward Tier III approaches are essential to reduce uncertainties and support more robust GHG inventories, life cycle assessments, and mitigation strategies. |

| Conteúdo: | Abstract: Micro- and nanoplastics (MNPs) have been increasingly detected in human tissues, including the placenta and, more recently, the brain. Their capacity to cross biological barriers such as the placenta and the blood–brain barrier raises significant concern for sexually dimorphic neurodevelopment. Brain sexual differentiation, orchestrated by steroid hormones, neuroimmune signaling, and epigenetic programming during early life, represents one of the most hormonally sensitive and developmentally critical targets of environmental disruption. In this narrative review, we synthesize evidence positioning MNPs as potential endocrine and epigenetic disruptors that may reprogram hypothalamic circuits governing reproduction and socioemotional behavior within a DOHaD framework. Evidence is stronger in animal and cellular models, implicating oxidative stress, neuroinflammation, apoptosis, and disrupted neurotransmission as central mechanisms; however, sex-specific endpoints remain underexplored and human data are still limited. This review adds a novel integrative perspective by focusing on sexually dimorphic hypothalamic nuclei and by outlining testable, sex-informed hypotheses. We highlight key methodological priorities for future research, including environmentally relevant exposures, explicit consideration of sex as a biological variable, multi-omics approaches, and longitudinal designs. |

| Conteúdo: | Abstract: Anthracnose, caused by the Colletotrichum sp. gloeosporioides complex, severely affects guava quality, highlighting the need for sustainable alternatives to synthetic postharvest fungicides. This study is the first to evaluate modulated UV-C radiation as an innovative approach to controlling postharvest diseases and extending guava shelf-life. The modulation frequency significantly influenced mycelial growth and conidial germination, following a quadratic model (R2 = 0.98), with maximum efficacy at ~30 Hz, reducing germination to 5.3 × 104 CFU per plate. In vivo, the combinations of 0.99 kJ m−2/30 Hz and 0.66 kJ m−2/45 Hz inhibited anthracnose incidence and severity. Most physicochemical parameters remained unaffected after seven days of storage. However, treated fruits showed a higher hue angle (h) and lower a*, indicating the maintenance of shades closer to green due to slower chlorophyll degradation, and firmness was preserved, suggesting delayed ripening. Modulated UV-C also significantly reduced the respiration rate, lowering the climacteric peak. These findings demonstrate that anthracnose control depends on the modulation frequency, with 0.99 kJ m−2/30 Hz being particularly effective. Modulated UV-C radiation represents a promising, sustainable, and effective strategy for improving guava postharvest quality and shelf-life. |

| Conteúdo: | Abstract: In postharvest disease (PHD) control experiments, treatments with the same observed values for all their replicates are frequently present, which leads to one or more treatments with zero observed variance—this type of data are referred to as data with zero-variance patterns. Such data patterns clearly violate the assumptions of classical parametric statistical models. These patterns are frequently overlooked in phytopathological studies, thus resulting in inadequate inference. In vivo experiments evaluating postharvest disease (PHD) control in fruits involve diverse response variables describing disease progress over time, including binary, discrete, and continuous data, which require different probability distributions for appropriate statistical modeling. These experiments typically follow a completely randomized design (CRD), with individual fruits serving as experimental units and being evaluated over a time interval (t, days) defined by the host–pathogen system. Disease progress is commonly quantified by incidence, severity (measured by discrete scales or mean lesion diameter, MLD), and the area under the disease progress curve (AUDPC). In PHD datasets, high/very low treatment efficacy often leads to zero/maximum values across all replications which produces zero-variance patterns, thus rendering the use of general linear models (GLM) unsuitable. Under such conditions, alternative nonparametric approaches or permutation tests are required, including Fisher’s exact test for incidence and tests for nonparametric contrasts for severity or AUDPC. Our objective is to contribute towards the adoption of more adequate statistical inferential methods for analyzing data from PHD experiments. |

| Conteúdo: | Abstract: Groundwater in North America is contaminated with per- and polyfluoroalkyl substances (PFAS) at more than 9500 locations. A major source of this contamination is aqueous film-forming foam (AFFF), widely used for fire suppression at military facilities and airfields. Many of the thousands of PFAS remain poorly characterized and are not amenable to targeted quantitative analytical methods, which allow them to remain undetected. Suspect screening, an analytical strategy that searches for potential or likely compounds from a predefined list without requiring analytical reference standards, combined with liquid chromatography-high resolution tandem mass spectrometry (LC-HRMS/MS), has emerged as an alternative or complementary approach to classical targeted analysis. Herein, an accessible suspect screening workflow was developed using data-dependent acquisitions and the NIST suspect list of 4712 PFAS, processed with TraceFinder software, followed by FreeStyle MS2 spectral management. Eleven PFAS were identified in AFFF-impacted groundwaters, including six compounds previously undetected by targeted experiments: 1H-perfluoropentane, 1H-perfluoroheptane, perfluorobutylsulfonamide (FBSA), perfluorohexanesulfonamide (FHxSA), perfluoropropanesulfonamide (FPrSA), and perfluoropropanesulfonic acid (PFPrS). Direct sample injection imposed sensitivity limitations, likely preventing the detection of additional PFAS present at lower concentrations. Nevertheless, the simplicity and reduced software investment requirements of this workflow make it a promising approach for broad adoption by the scientific community. |

| Conteúdo: | Abstract: Trichoderma species are recognized as versatile fungi with significant roles in biocontrol of plant diseases, promoting plant growth and safeguarding against various environmental threats. Despite their benefits, the biodiversity of indigenous Trichoderma isolates in the semi-arid region of Brazil\\\'s Caatinga biome remains largely unexplored. This untapped diversity holds promise for identifying potential biocontrol agents against soilborne plant pathogens. Here, we conducted molecular identification and morphological characterization of 14 indigenous Trichoderma isolates from both undisturbed (native) and melon agricultural areas of the Caatinga biome. Subsequently, we evaluated the direct antagonism (competition or mycoparasitism) and volatile compounds (VCs) antibiosis of these Trichoderma species against five representative soilborne plant pathogens: Fusarium sulawesiense, Fusarium solani, Macrophomina phaseolina, Rhizoctonia solani, and Pythium myriotylum. A distinct Trichoderma species composition was observed in undisturbed and cultivated areas, influenced by soil chemical properties. Thermotolerance was found to be more associated with ecological niche than specific species or isolates, with isolates from melon-grown areas exhibiting higher heat tolerance. Isolates from both undisturbed and cultivated area demonstrated antagonism through competition-mycoparasitism and VCs-mediated antibiosis, though the impact on pathogens varied. Trichoderma asperelloides and Trichoderma aperellum from melon-grown areas stood out as the best conidial producers by solid-state fermentation. Our findings highlight key biocontrol traits in Trichoderma species alongside their thermotolerance and conidial production, underscoring their potential for development as biocontrol agents in the Caatinga biome. We also discuss the implications of these findings for employing Trichoderma in biological control strategies against soilborne diseases in challenging environmental conditions. |

| Conteúdo: | Abstract: Fungi from the Botryosphaeriaceae family are causal agents of stem blight and affect macadamia at all developmental stages, being particularly lethal to plantlets. This study evaluated the effectiveness of Bacillus spp. isolates in controlling the disease in macadamia plantlets and the susceptibility of macadamia varieties to Lasiodiplodia pseudotheobromae (Botryosphaeriales: Botryosphaeriaceae), considering rootstock-scion combinations. Three macadamia scion varieties (IAC 4-12B, HAES 333, and HAES 741) were inoculated with three L. pseudotheobromae isolates. The rootstock (HAES 10–14) remained the same. Bacillus spp. isolates were selected for their antagonistic properties and tested for disease control in plantlets. Disease severity varied depending on the rootstock-scion combination and the L. pseudotheobromae isolate. Bacillus velezensis (CMAA1935 and CMAA1936) and B. subtilis (CMAA1934) (Bacillales: Bacillaceae) reduced disease severity, but their efficacy depended on the scion variety. Our findings indicate that resistance to stem blight in grafted plantlets varies with the L. pseudotheobromae isolate and the scion genotype, also influencing disease severity in the rootstock. These results suggest that Bacillus spp. may serve as a complementary tool for managing stem blight, particularly when resistance varies with scion-rootstock combinations. |

| Conteúdo: | Abstract: Floral diseases of macadamia, such as raceme blight, are among the main limiting factors for crop production, and the low availability of registered products for phytosanitary management further aggravates this challenge. In this context, biocontrol agents emerge as a sustainable and effective alternative for integrated disease management. This study aimed to select antagonistic bacteria for the control of raceme blight in macadamia, caused by Cladosporium xanthochromaticum. For this purpose, bacteria were isolated from macadamia racemes, identified, and tested against the phytopathogen in both in vitro and in vivo experiments (racemes and field plants). Their mechanisms of action and compatibility with pesticides registered for the crop were also evaluated. Strains of Serratia ureilytica and Bacillus subtilis proved effective in controlling the disease in the field. S. ureilytica reduced the incidence of C. xanthochromaticum by 27.04% to 35.38% and its sporulation by 52.04% to 52.65%. Meanwhile, B. subtilis was effective in reducing sporulation in racemes by 16.25% to 26.08%. Both strains demonstrated inhibitory activity through volatile and non-volatile compounds, as well as competition for nutrients. The strains were compatible with all pesticides tested, except copper hydroxide, to which S. ureilytica was sensitive. The results indicate that the selected strains can be incorporated into the integrated disease management of macadamia, contributing to the reduced reliance on chemical pesticides. |

In this context, the present study evaluated the impact of bee pollen addition as a nutrient source for wild yeasts on the physicochemical composition, color, phenolic compound profile, and antioxidant capacity of mead. Three distinct meads were produced by applying spontaneous fer- mentation of Apis mellifera honey: a control (honey diluted in water to 22 ◦Brix); honey diluted in water and supplemented with bee pollen (30 g L−1 ); and honey diluted in water and supplemented with a commercial fermentation activator composed of ammonium phosphate (0.4 g L−1 ). The use of nitrogen sources for wild yeasts reduced the fermen- tation time by up to 14 days. Notably, only bee pollen caused darkening of the mead, resulting in a more yellowish color. Seventeen phenolic compounds were identified in the meads, including phenolic acids, flavonols, and flavanols. The mead supplemented with bee pollen exhibited higher antioxidant capacity and a greater content of identified phenolic compounds, particularly quercetin-3-β-D-glucoside, at a concentration 100 times higher than that in the control (23.5 mg L−1 ). These findings indicate that bee pollen acts as a multifunctional fermentative modulator, improving the fermentative performance of wild yeasts and promoting phenolic enrichment, thereby supporting its application in the development of mead. |

| Conteúdo: | Abstract: The manipulation of beneficial microorganisms transcends conventional biotechnology to become the biogenic infrastructure of a resilient agriculture. Although the CRISPR/Cas9 system has established itself as a superior genome editing tool, mainly due to its precision, simplicity, and cost-effectiveness, its full translation into agromicrobial ecosystems faces critical biological and technical bottlenecks. This review comprehensively evaluates the implementation of CRISPR systems in fundamental taxa, such as entomopathogenic fungi, Trichoderma, Bacillus, and diazotrophic bacteria, confronting systemic challenges that include the cytotoxicity of Cas9 overexpression, the frequency of off-target mutations, and structural instability in organisms. Additionally, Brazilian bioinnovation has subverted these limitations through the development of marker-free genomic architectures and the optimization of virulence factors in biocontrol agents, establishing a new paradigm of microbial engineering. The evolution of these tools requires not only the improvement of delivery methods, currently inefficient in several species, but also a radical modernization of regulatory frameworks. This paper discusses how the legal classification of these organisms under Brazilian biosafety will shape the future of intellectual property (IP) and the commercial viability of next-generation microbial biopesticides and inoculants. Ultimately, it proposes that overcoming these technical obstacles and changing public perception are imperative for genome editing to catalyze a sustainable revolution in global agricultural productivity. |

The experiment was conducted in a randomized complete block design arranged in a 12 & times; 2 factorial scheme with three replications, and disease severity was assessed at the R9 stage by means of the percentage of leaf area affected. Planting season significantly affected disease severity, and a significant season & times; treatment interaction was detected, indicating that the effects of cultivar and cropping system depended on planting season. Disease severity was higher in the June planting, whereas December planting reduced severity by 69.60%. Intercropping reduced disease severity for most cultivars during the June planting. Monocropping systems showed higher grain yield due to greater plant density, averaging 2.11 and 2.29 t ha- 1 in June and December planting, respectively, while intercropping averaged 1.15 and 1.22 t ha- 1. However, intercropped cowpea maintained stable productivity per plant despite a 50% reduction in plant density. These results demonstrate that adjusting planting date and adopting intercropping with adapted cultivars can simultaneously reduce powdery mildew severity and maintain productive stability in semiarid cowpea systems. |

| Conteúdo: | Farmland abandonment is becoming a growing land use challenge in the Brazilian Cerrado, yet its extent, spatial distribution, and underlying drivers remain poorly understood. This study addresses the following question: Can deep learning methods reliably identify abandoned farmlands in tropical savanna environments using multispectral satellite images? To answer this question, we used a Fully Connected Neural Network (FCNN) classifier to map abandoned farmlands in the municipality of Buritizeiro, Minas Gerais State, Brazil, using Sentinel-2 images acquired in 2018 and 2022. Seven land use and land cover (LULC) classes were mapped using visible and near-infrared bands, spectral indices, spectral mixture components, and principal components as input parameters for the CNN. The LULC map for 2022 achieved high classification performance (overall accuracy = 94.7%; Kappa coefficient = 0.93). Agricultural areas classified in 2018 as annual croplands, cultivated pastures, eucalyptus plantations, or harvested eucalyptus that transitioned to grasslands or shrublands in 2022 were considered abandoned. Based on this definition, we identified 13,147 hectares of abandoned land in 2022, representing 4.7% of the municipality’s agricultural area in 2018. Most abandoned areas corresponded to eucalyptus plantations established for charcoal production. This study provides the first deep learning-based assessment of farmland abandonment in the Cerrado. Our findings demonstrated the potential of FCNN classifiers for detecting abandoned farmlands in this biome and provide important contribution for public policies focused on ecological restoration, carbon sequestration, and sustainable agricultural planning. |

| Conteúdo: | Eleusine indica (L.) Gaertn., commonly known as goosegrass, is one of the most troublesome weed species worldwide. In Brazil, the increasing number of herbicide-resistance cases, particularly to glyphosate, has made goosegrass the most agronomically significant weed species in the country. Given its rapid spread in recent cropping seasons, this review compiles current knowledge on goosegrass biology and herbicide resistance to support the development of more effective integrated weed management strategies. Successful control approaches must consider the species’ biological characteristics and the potential occurrence of herbicide-resistant populations in target areas. The adoption of preventive practices (e.g., cleaning machinery, purchasing seeds from certified companies), cultural practices (e.g., balanced fertilization, use of regionally cultivars, phytotechnical adjustments), and mechanical practices (e.g., mowing) can optimize the effectiveness of herbicides in controlling this weed. Chemical control of goosegrass should rely on pre-emergence herbicides, along with post-emergence products featuring different mechanisms of action, with sequential applications anticipated. Implementing integrated weed management systems offers the potential to mitigate the current losses and damage caused by goosegrass. |

| Conteúdo: | Abstract: Paddy rice cultivation is an important anthropogenic source of atmospheric methane (CH4). Quantifying CH4 emissions under specific crop conditions is essential to improve the accuracy of global greenhouse gas estimates. Computer modeling simulation may contribute to a better understanding of how different environmental factors affect seasonal CH4 emissions, thereby supporting mitigation strategies. The objective of this study was to compare three-growing-season field measurements of CH₄ emissions from a paddy rice field, under pre-germinated system, in Pindamonhangaba, São Paulo State, Brazil, with estimates of emissions obtained from simulations using the DeNitrification– DeComposition (DNDC) model under the same conditions. Methane fluxes were measured weekly using the closed-chamber method, and model input parameters were derived from the site-specific conditions (soil, crop, management, and climate) for each season. Daily pattern of CH4 fluxes and seasonal emissions were obtained by DNDC for the evaluated growing seasons. The mean seasonal CH4 fluxes quantified in the field ranged from 231.72 ± 40.23 to 285.25 ± 51.66 kg C-CH4 ha-1, while those obtained using DNDC ranged from 210.53 to 267.39 kg C-CH4 ha-1. The model results fell within the variability of field quantifications, with one season slightly above the upper observational limit, demonstrating the good accuracy of this simulator to estimate seasonal methane emissions for the site. However, in spite of the simulated daily methane fluxes have showed a temporal trend similar to that observed in the field for all the growing seasons, the magnitude of the simulated emissions differed from some observed values. |

| Conteúdo: | Abstract: Seed physiological quality significantly affects crop performance. Besides proper crop establishment, pre-emergence herbicides constitute one major weed-control strategy. This study evaluated selectivity of pre-emergence herbicides in soybean sown with seeds of high and low physiological quality. The experiment was conducted in Rio Verde, Brazil, in a 4x2 randomized block design, with four replications. The treatments consisted of low and high-quality seeds combined with pre-emergence herbicides [imazethapyr + flumioxazin], diclosulam and [sulfentrazone + diuron], and a control. Plants from high-quality seeds showed better performance than those grown from low-quality seeds. This resulted in a greater emergence speed index, plant height, inter-row cover, NDVI, plant population, first pod height, thousand-grain weight, and grain yield. Regardless of seed quality, pre-emergence herbicides did not influence the evaluated traits. |

| Conteúdo: | Abstract: This study aimed to assess the potential for agricultural expansion into pasture areas with varying degrees of degradation in Brazil, providing both quantitative and spatial analyses at different scales – national, biome, microregion, and municipality. The proposed method was based on remote sensing data analysis and on data integration on a geographic information system to map degraded pasturelands, lands with natural agricultural suitability, infrastructure (roads and warehouses), croplands, climate risk agricultural zoning, and legal or environmental constraints posed by indigenous territories, Quilombola communities, agrarian settlements, and conservation units. Results indicate that approximately 28 million hectares of moderately to severely degraded pastures present good to high potential for conversion into croplands, considering the base year of 2022. The Cerrado biome demonstrated the highest potential, accounting for about 14.5 million hectares. The ten municipalities selected by the Digital Agriculture Development Science Center (Semear Digital) initiative and their corresponding microregions presented a total of 34.1 thousand hectares and 266.5 thousand hectares, respectively. The present approach enabled the quantification and spatialization of agricultural potential through a multiscale approach, providing support for decision-making in the formulation of public policies aimed at the restoration of degraded areas. |

| Conteúdo: | Abstract: Corn is Brazil’s second-most cultivated crop (21 Mha). Second-crop corn (SCC) represents 80% of this area and accounts for 8% of global production, making it a promising feedstock for food, feed, and biofuels with reduced land-use change (LUC) pressure. Assessing the net CO₂ balance (NCB) from direct LUC (dLUC) and soil management practices (SMP) is essential to quantify its decarbonization potential. This study provides the first national-level mapping of SCC in Brazil for 2023, including land-use/-cover transitions over the previous 20 and 10 years and associated NCB. SCC expansion over natural vegetation declined from 13% (2003–2023) to 3.6% (2013–2023). The 20-year dLUC NCB ranged from 0.6 to 0.9 t CO2 ha⁻¹ yr⁻¹, below published values. SMP contributed −0.1 to −0.2 t CO2 ha⁻¹ yr⁻¹, offsetting ~20% of dLUC. Combined dLUC+SMP NCB for SCC ethanol ranged from 2.3 to 5.3 and 0.3 to 1.5 g CO2 MJ⁻¹ for the respective periods. |

| Conteúdo: | Seasonal fluctuations in soil chemical properties play a central role in regulating biogeochemical processes and fertility in Amazonian forests. This study evaluated how rainy and dry seasons influence soil organic carbon (C), total nitrogen (N), and pH under native Bertholletia excelsa groves in the Tapajós National Forest, Pará, Brazil. Thirty soil samples (0–20 cm) were collected during each season and analyzed individually using standardized laboratory procedures and appropriate statistical tests. Significant seasonal differences were detected for C (p = 0.0001) and N (p = 0.013), whereas pH remained stable across periods (p > 0.05). Organic carbon increased markedly during the dry season, reflecting the accumulation of partially decomposed litter and humic substances under reduced moisture and slower decomposition. In contrast, total nitrogen decreased slightly but significantly, suggesting enhanced microbial immobilization during drought. Together, these patterns indicate that hydrological seasonality modulates the balance between nutrient release in the wet season and organic matter preservation in the dry season. From a management perspective, maintaining litter cover and minimizing soil disturbance during the dry season are essential to sustaining nutrient retention, soil structure, and ecosystem resilience. By integrating seasonal contrasts in C, N, and pH, this study provides empirical evidence of the mechanisms governing nutrient dynamics in soils beneath native Brazil-nut trees, advancing the understanding of biogeochemical functioning and offering a basis for sustainable management of Amazonian extractive systems. |

Por meio de uma metodologia qualitativa baseada em análise documental, examinamse as dinâmicas de cooperação entre agricultores familiares, pesquisadores, instituições públicas e outros atores sociais. Destacase como essas redes contribuem para o fortalecimento da transição agroecológica ao fomentar a troca de conhecimentos, a inovação social e a articulação de políticas públicas que apoiam práticas sustentáveis. Os resultados indicam que essas redes são essenciais para superar desafios comuns, como o acesso limitado a mercados, insumos e assistência técnica especializada. Além disso, atividades coletivas, como macro-oficinas, oficinas participativas e campanhas de conscientização, demonstraram ser ferramentas eficazes para promover a cocriação de soluções em diversos territórios. Apesar das limitações financeiras e institucionais, as redes multiatores emergem como espaços de aprendizagem e inovação cruciais para a viabilidade dos sistemas agroflorestais. Este estudo contribui para o debate sobre como as redes sociais podem desempenhar um papel estratégico na transição para modelos agrícolas mais resilientes e sustentáveis no Brasil. |
