Research Interests

Comparative Vertebrate Reproduction

Dr. Trauth's research involves the natural history, reproductive anatomy and life cycles of amphibians and reptiles.  He continues to investigate aspects of the reproductive ecology of plethodontid salamanders primarily of the genera Plethodon and Desmognathus.  Specifically, he examines the nesting ecology, spermathecal anatomy, duration of sperm storage, and sperm morphometrics in these salamanders.  In reptiles, he has a wide variety of interests including lizard nesting ecology, snake urogenital anatomy, and Rathke's glands and sperm morphometrics in turtles.
