Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...

As cianobactérias são organismos procariontes, assemelhando-se à s bactérias, e realizam fotossÃntese com produção de oxigênio, como células vegetais. As florações desses organismos podem causar problemas em mananciais de abastecimento público, pois algumas espécies podem produzir cianotoxinas.

Historical shifts, geographic biases, and biological constraints shape mammal species discovery
Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.

The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately
