A SURVEY AND ANALYSIS OF THE UNIONID MOLLUSKS OF THE PLATTE RIVERS OF NEBRASKA AND THEIR MINOR TRIBUTARIES

摘要

A survey conducted in the Platte basins in Nebraska between 1972 and 1995 documented a bivalve fauna consist-ing of sixteen native unionids and one introduced exotic spe-cies. Five new taxa were confirmed for the Platte basins in Nebraska, increasing the total reported for the region to eighteen unionids and one exotic taxon. The greatest species diversity was found to have existed in tributaries of the Platte rivers, while bivalves were uncommon in the main channel of the Platte River. Man-made environments provide significant habitat for some bivalves in the region.
