We investigated the accumulation and adverse effects of toxic and non-toxic Microcystis in the edible clam Corbicula leana. Treated clams were exposed to toxic Microcystis at 100 μg of MC (microcystin)-LReq L-1 for 10 days. The experimental organism was then placed in toxin-free water and fed on non-toxic Microcystis for the following 10 days for depuration. Filtering rates (FRs) by C. leana of...

Valve closure behavior in freshwater clam Corbicula fluminea is a biologically sensitive endpoint. The purpose of this paper was to derive an electrophysiological response model of C. fluminea to assess copper (Cu)-sodium (Na) interactions in gill membrane, whereby valve closure behavior and Cu toxicity could be monitored. The proposed model was based on the integration of Cu bioavailability, N...

The bioinvader bivalve Corbicula fluminea (Müller, 1774) is known in the Río de la Plata River since about 35 years ago. This time lapse fills a gap taphonomical studies, that comprises usually strictly contemporaneous or at best centuries-old phenomena. We sampled shells of this species one locality two occasions with same methodology. Fragmentation, presence periostracum, corrasion, bioerosio...

Bear Creek is a tributary of the Tennessee River in northwestern Alabama and northeastern Mississippi. The watershed supports diverse freshwater mussel assemblage including several species conservation concern. We conducted survey at 55 sites Mississippi portions its largest tributary, Cedar Creek, during September October 2020. found total 30 species, which 25 were represented by live individu...

The invasion of the Asiatic clam Corbicula fluminea in South America has already reached Patagonia. Despite well-known direct and indirect impacts that this species exerts on fresh-water ecosystems, particularly benthic communities, few studies have been undertaken its effect composition structure aquatic macroinvertebrate assemblages. This study evaluated effects C. assemblages Limay River, on...
