Recent phylogenetic reassessment of the lungless salamanders (Plethodontidae) confirmed a major life-history reversal-from direct development to an aquatic larval stage-in the dusky salamanders (Desmognathus) of eastern North America. This reversal initiated high rates of lineage accumulation, reputedly generating the species richness and ecological breath that now characterize Desmognathus. Certain important aspects of the radiation, e.g., ecomorphological evolution, have been identified… CONTINUE READING
