Campylobacter jejuni strains isolated in Brazil have important virulence related genes and survive to different stress conditionsNARA Subscribed
Campylobacter jejuni has been reported as the leading bacterial pathogen that causes foodborne gastroenteritis in humans in many countries. This study aimed to assess the survival of 46 C. jejuni strains isolated from food (14), humans (18), and animals (14) in Brazil from 1996–2016 under different stress conditions, evaluate their invasion and survival capacity in Caco-2 cells and U-937 macrophages and determine virulence usi...
Background and objectives Silicon (Si) has been widely reported to enhance tolerance to abiotic stresses, including drought, in several crops. However, the long-term effects of soil-applied Si remain insufficiently explored. This study aimed to assess dry matter production, plant nutritional status, C:N:P:Si stoichiometry, and soil Si availability in ratoon sugarcane under water deficit and the residual effect of an amorphous...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Long-term crop diversity improves soil chemical attributes, nutrient cycling and soybean yieldNARA Subscribed
Cover crops have the potential to reduce agricultural inputs, but the long-term impacts of cover crops on soil chemical properties and nutrient cycling in tropical systems are not fully understood. This study evaluated the impact of different cover crop systems under long-term no-tillage on shoot dry mass (SDM) production, nutrient cycling, soil chemical properties, and soybean yield in succession in the Cerrado region of Mato...
Single and combined chronic toxicity of polystyrene nanoplastics (PSNP) and clothianidin on collembolans and enchytraeidsNARA Subscribed
This study assessed the chronic toxicity of polystyrene nanoplastics (PSNP) and clothianidin (CLO), individually and as a binary mixture, on enchytraeids Enchytraeus crypticus and collembolans Folsomia candida . The assays were performed according to ISO protocols, using a tropical soil (Entisol) as the test substrate. The mixture assays were performed using equitoxic concentration, standardized according to the preliminary EC...
Quantifying animal movements is necessary for answering a wide array of research questions in ecology and conservation biology. Consequently, ecologists have made considerable efforts to identify the best way to estimate an animal's home range, and many methods of estimating home ranges have arisen over the past half a century. Most of these methods fall into two distinct categories of estimators that have only recently been d...
Waterfowl Move Less in Heterogeneous and Human‐Populated Landscapes, With Implications for Spread of Avian Influenza VirusesNARA Subscribed
Animal movements contribute to the spread of infectious diseases and are driven in part by environmental conditions. We investigated the links among the environment, animal movement, and infectious disease dynamics in waterfowl, which are among the primary wildlife hosts of avian influenza viruses. By combining telemetry data on 4606 individuals from 26 waterfowl species with data on land cover, weather, and vegetation, we fou...
