THE UNIONID MOLLUSKS OF THE UPPER KANSAS BASIN OF NORTHWESTERN KANSAS ND SOUTHWESTERN NEBRASKA

摘要

a qualitative survey of the Upper Kansas Basin resulted in the documentation of a unionid fauna consisting of twenty- one native taxa, as well as the introduced bivalve Corbicula fluminea. Biological diversity was greatest in the extreme eastern portion of the basin with the highest concentrations occurring in the habitat-rich eastern-most creeks.
