Geological Investigations of the Neogene

More than a third of the United States population lives in counties directly on the shoreline, making them vulnerable to hazards associated with changing sea level and storm surges associated with hurricanes and severe storms. The geologic record contains many examples of past intervals of warm climate and high sea level. "Geological Investigation of the Neogene" is examining proxy records of...

Using Molecular Tools to Recalibrate Freshwater Mussel Taxonomy with a Focus on Imperiled Species

Freshwater mussels of the family Unionidae, also known as naiads, pearly mussels, freshwater clams, or unionids, are a diverse group of bivalve mollusks that are distributed on every continent except Antarctica. Approximately 300 species are known from the United States, with most of this diversity residing in rivers of the Southeast where many endemic taxa have evolved.
