Species of the genus Senga comprise a group of bothriocephalidean cestodes that predominantly parasitize freshwater teleost fishes, causing severe histopathological alterations due to scolex attachment to the digestive tract or obstruction of the intestinal lumen. The Siamese fighting fish Betta splendens is the type-host of Senga besnardi , the type species of the genus known only from the original description. Despite the im...

Residual herbicides are widely used in weed management; however, their persistence in the environment can lead to agronomic and ecological impacts. This study assessed bacterial isolates obtained from sugarcane soil with a history of diuron exposure for their ability to increase diuron dissipation under controlled conditions. Forty-two bacterial isolates were obtained, of which 18 tolerated the commercial formulation at 1,000...

Mimosa L. comprises approximately 620 species of socioeconomic and environmental importance, with about half occurring in the Brazilian Cerrado. Despite this diversity, cytogenetic studies in the genus remain limited, with most restricted to chromosome counts. We investigated 11 populations of seven Mimosa species, focusing on the heterochromatin distribution (CMA + bands), and nuclear DNA content. Polysomaty was observed in r...

The effects of global climate change on biodiversity and ecosystem functioning are unevenly distributed in the geographic space. Identifying sites more suitable to sustain biodiversity in a changing climate is essential to both species conservation and restoration strategies at different scales. Here, we map terrestrial climate‐resilient sites for biodiversity across Brazil to identify sites with greater chances of providing s...

Increasing reports of zoonotic avian influenza virus (AIV) spillovers to mammals signal critical shift in their ecology and raise substantial public health concerns. The highly pathogenic avian influenza H5N1 clade 2.3.4.4b has driven this expansion, with genetic adaptations enhancing replication in mammalian hosts. Adaptations have been identified in diverse carnivore species, including American mink ( Neogale vison ), red fo...
