Distributional and habitat survey of freshwater mussels (Unionidae) in Texas rivers.
Cook, Michael James.

Distributional and habitat survey of freshwater mussels (Unionidae) in Texas rivers. - 134 p.

Adviser: William Gibson.

Thesis (M.S.)--Stephen F. Austin State University, 2008.

Freshwater bivalve mollusks (Unionidae) are among the most imperiled faunal groups in North America due to anthropogenic habitat alterations. This study conducted between September 2006 and July 2007 determined the present population status of unionids in the Brazos, San Antonio, and Lower Sabine River basins. Qualitative and Semi-quantitative sampling methods were used to conduct our survey. Abiotic parameters (pH, dissolved oxygen, turbidity, water temperature, water velocity, depth, TDS and substrate type) were recorded for each location and site. Thirteen species were found in the Brazos River Basin, 4 species in the San Antonio River Basin, and 1 species in the Sabine River Basin. Water turbidity and velocity at 60% of depth were significantly associated (Beta=0.645; p<0.01, Beta= -0.39; p<0.05, respectively) with mussel diversity and abundance, respectively. Therefore, select abiotic parameters affect the diversity and abundance of freshwater mussels in these river basins.
