Molecular species delimitation refines the taxonomy of native and nonnative physinine snails in North America

Abstract Being able to associate an organism with a scientific name is fundamental to our understanding of its conservation status, ecology, and evolutionary history. Gastropods in the subfamily Physinae have been especially troublesome to identify because morphological variation can be unrelated to...
