Corbicula fluminea is an Asian mussel that has aggressively invaded freshwater habitats worldwide, causing damage both economically and with the disappearance of native species. In Brazil, this species present in almost all watersheds, including areas Federal Conservation Units. context, work reported first record C. Carajás mosaic, Pará, a Area. Collections were made September February 2021 Ma...

The purpose of this study is to develop a mechanistic model to describe a conceptually new "flux-biological response" approach based on biotic ligand model (BLM) and Michaelis-Menten (M-M) kinetics to allow the linkage between valve closure behavior and sodium (Na) transport mechanism in freshwater clam Corbicula fluminea in response to waterborne copper (Cu). We test the proposed model against...

Corbicula fluminea is an invasive clam originally from Asia that threatens the biodiversity of freshwater communities around world. It has greatly expanded in Brazil since its first record. We report here occurrence C. Piauí state, Parnaíba river basin and, provide assessment current distribution Brazil. The compiled data include 382 records 22 states and Federal District,...

Selenium uptake from food (assimilation efficiency) and dissolved phase (influx rate) as well as loss kinetics (efflux rate) were compared between two bivalves, Corbicula fluminea and Potamocorbula amurensis. The effects of salinity and temperature on these kinetic parameters for both clam species also were evaluated. The Asiatic clam, C. fluminea, more efficiently assimilated Se associated wit...
