Ion ATPases in the tissues of aquatic animals are sensitive to metal exposures. Mussels filter-feeding and have a sedentary lifestyle that makes them good bio-indicator animals. Thus, present study was carried out investigate effects copper (0, 30, 90 µg/L) on activities Na-ATPase, Mg-ATPase, Ca-ATPase gill muscle freshwater mussels (Unio tigridis) different exposure durations 7, 14, 21 days). ...

ABSTRACT The freshwater mussel Unio durieui is a rare bivalve endemic to North African watersheds. Although this an important species from ecological and conservation perspective, information on its genetic diversity population structure lacking. Here, we combine geometric morphometric molecular analyses characterize evaluate the status of populations endangered four Tunisian watershed basins (...

Freshwater mussels (Order Unionida) are highly threatened. Interspecific competition for food sources with invasive alien species is considered to be one of the factors responsible their decline because successful invaders expected have wider trophic niches and more flexible feeding strategies than native counterparts. In this study, carbon (?13C: 13C/12C) nitrogen (?15N: 15N/14N) stable isotop...
