Considering the ecological relevance of amphibians and the widespread agricultural use of herbicide mixtures, investigations addressing their joint toxicological effects are increasingly necessary. Here, we investigated the effects of a mixture of two commercially formulated herbicides widely used in combination in agriculture—2,4-D-based herbicide (DBH) and a glyphosate-based herbicide (GBH)—on tadpoles of Physalaemus cuvieri...

Nutrition is a key determinant of performance, carcass traits, and production efficiency in beef cattle. In this context, feed additives have emerged as a promising strategy to enhance nutrient utilization and reduce production costs. We aimed to evaluate the effects of replacing urea with a product extruded urea enriched with essential oils (NFeed ® ) on nutrient intake, performance, blood parameters, and feed cost in feedlot...

The emergence of new viral strains has been frequently associated with the onset of outbreaks in different epidemiological settings. This study investigated an acute gastroenteritis (AGE) outbreak, which occurred at a university campus in southern Brazil, in 2024, affecting approximately 30–40% of undergraduate students, with over 400 reported cases. The objectives were to describe the epidemiological and molecular features of...

Bees are essential for ecosystem functioning, pollinating many wild and crop plant species. Predicting which species are most vulnerable to global changes, and how their loss may impact ecosystems and human well-being, is critical. Comprehensive information on bee response and effect traits is fundamental to these assessments. However, the Raunkiærian shortfall—insufficient trait data—remains significant for bees, particularly...

Aim To investigate the spatial and temporal dynamics of fish assemblages across the Northern Brazilian Shelf, a vast and complex ecosystem influenced by the Amazon River plume, we aimed to identify fish assemblage types, understand transitions between them from the river mouth to offshore reefs, and examine seasonal changes related to plume dynamics. Location Northern Brazilian Shelf (Western Atlantic Ocean), from the Amazon R...
