Inaccurate systematics confound our ability to determine evolutionary processes that have led to the diversification of many taxa. The North American freshwater mussel tribe Lampsilini, Ihering, 1901, is one of the more well-studied groups in Unionidae; however, many supraspecific relationships between lampsiline genera remain unresolved. Two genera that have been largely overlooked are Leptodea and Potamilus, which have both been hypothesized to be non-monophyletic. We set out to resolve supraspecific relationships in Lampsilini and test the monophyly of Leptodea and Potamilus using an integrative approach. Here we present details on our molecular, morphological, and distribution data.

Abstract (from AMSJournals): Riverine ecosystems are dependent in large part on the climate of the region, and climate change is expected to alter climatic factors of interest, such as precipitation, temperature, and evapotranspiration. In central Texas, precipitation is expected to decrease while temperature increases as the climate changes. Drought and flooding events are also expected to increase in the region, which will also affect streamflow and stream temperature in riverine ecosystems. Numerous studies have assessed the potential impacts of climate change on riverine species. This study examines the projected climate changes, determines potential changes in streamflow and stream temperature for river basins...
