Abstract Fungal and bacterial communities were characterized at three soil depths (0–3.5 cm, 3.5–7.5 cm, and 7.5–15 cm) in a 15-year no-till field experiment involving diversified crop rotations with two levels of nitrogen fertilization and soybean monoculture. We hypothesized th...

Abstract Guanabara Bay (GB) is an environment contaminated by metals, and it is the bay that receives the most dredging in Brazil and South America. Previous studies have shown the impact of dredging on planktonic and benthic species, which were not correctly measured by the Braz...

Purpose This research aims to evaluate how manufacturing processes influence stress-corrosion cracking in two supermartensitic stainless steels (SMSSs) classified as UNS S41426. The samples were manufactured by forging and hot rolling process. Design/methodology/approach The micr...

A scientific commons for AI: community governance as the missing layer in global science
Foundation models are being absorbed into scientific workflows faster than the governance tools available to scrutinize them. Regulation, open-weight releases, transparency audits, public procurement standards, hybrid public-academic compute, and national sovereign-compute progra...

Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for i...

Abstract Purpose In-season optical sensor-based variable-rate nitrogen application (VRA) is designed to optimize nitrogen (N) management in maize (Zea mays L.) by aligning N inputs with real-time crop demand, yet reports on its performance are inconsistent. This study quantified...

Characterization of the ecological impacts of prescribed fire in South America: a review
Prescribed fire has been shown to offer substantial benefits to both human populations and ecosystems, but it can also cause environmental harm, such as reduced air quality and negative impacts on sensitive species. To support the appropriate use of prescribed fire, stakeholders...

Context The expansion of the agricultural frontier in northwestern Argentina occurred at the expense of deforestation of native forests, particularly in the Dry Chaco. This land-use change alters soil physical properties and soil organic carbon (SOC), compromising sustainability....

Ralstonia solanacearum species complex (RSSC) is a genetically diverse group of plant pathogens, yet genomic data from South America remain limited. Here, we characterize 13 RSSC strains isolated from tomato, pepper, and eggplant in northeastern Argentina. Phylogenetic analysis o...

Abstract Biochemical methane potential (BMP) assays are widely used to evaluate feedstocks for anaerobic digestion, but they are slow and resource-intensive. This study evaluated whether explainable machine learning can support transparent screening and hypothesis generation from...

A pair of duplicated SOC1 genes, DcSOC1-1 and DcSOC1-2, control vernalization requirement in carrot
Abstract Background Carrot vernalization requirement (VR), the amount of cold exposure needed for plants to become vernalized, strongly influences geographical adaptation of the crop and many agricultural practices, and this trait defines annual vs. biennial cultivars. Despite it...
