Abstract Aim Biogeography seeks to identify and explain the spatial distributions of species has become an important tool used by conservationists protect manage aquatic organisms. Texas, located in southwestern United States, is home 52 freshwater mussels, 9 which are endemic Texas 7 that neighboring states or countries. There have been two major attempts classify this fauna into biogeographic...

1. There may be bias associated with mark–recapture experiments used to estimate age and growth of freshwater mussels. Using subsets of a mark–recapture dataset for Quadrula pustulosa, I examined how age and growth parameter estimates are affected by (i) the range and skew of the data and (ii) growth reduction due to handling. I compared predictions from von Bertalanffy growth models based on m...

Over the last 30 years, relocation of freshwater mussels has been used as a conservation strategy for potential impacts from bridge construction and dredging operations. Improved methods have effectively increased relocated mussel survivorship rates of target species from ~ 50% to ~ 90% under ideal circumstances. Success to date is largely based upon survivorship rates without consideration of ...

Fipronil is widely used against insects in agriculture and ectoparasites domestic areas veterinary medicine. However, fipronil may influence non-target species as a result of the contamination aquatic ecosystems. The present study aimed to investigate acute sublethal effects freshwater mussels (Unio delicatus), species, with physiological, antioxidant action mechanisms histopathological observa...
