OverviewAI-generated summary
Donald B. Shepard's research focuses on the evolutionary history and genetic diversity of animal populations, particularly amphibians and reptiles. His work investigates lineage diversification, phylogeography, and historical biogeography, often employing molecular techniques such as DNA barcoding and sequence analysis. Recent publications explore the diversification of treefrogs in the Espinhaço Mountain Range, identify new species of frogs in Brazil, and clarify the phylogeography of slimy salamanders west of the Mississippi River.
Shepard also examines genetic diversity and historical demography in imperiled species, including moths. His research extends to ecological questions, such as evidence of sodium limitation in ants and termites in Neotropical savannas, and contributes to herpetofaunal checklists for protected areas in Brazil. He has published 58 works, accumulating 1,879 citations with an h-index of 20. He collaborates with Natalie A. Clay, with whom he shares two publications.
