My general research interests are in the systematics, ecology and conservation of amphibians and reptiles, particularly turtles. I currently have active research projects or supervise masters students with active research in:
- Conservation ecology of Western Pond Turtles
- Conservation genetics of Giant Garter Snakes
- Conservation genetics of marine turtles
- Conservation and invasive species issues in Hawaii
- Systematics of softshell turtles
- Eco-morphology of garter snakes
- Sexual selection and asymmetry in fence lizards
Past Masters Students:
- Eric Hansen – Eric is a biological consultant working on distribution and conservation ecology of Giant Garter Snakes in the Sacramento Valley.
- David Kelly – Dave studied demographics, reproductive biology, population genetics and morphology of western pond turtles in the Central Valley and Foothills and is now works for the USFWS in Sacramento.
- Akiko Masuda – Akiko is using genetic markers to trace origins of loggerhead marine turtles when she is not playing mommy to her 95 percentile in height and weight daughter.
- Julie Nelson – Julie studied the interactions of garter snakes, Yosemite toads and pacific chorus frogs in grazed and ungrazed meadows in the Sierra Nevada. She is now working on a sea turtle nesting beach in Costa Rica.
- Eric Olson – Eric did a herp inventory of the new Sutter Buttes State Park and is now working as a biological consultant for Condor Country Consultants.
- Jackson Shedd – Jackson is studying sexual selection and asymmetry in western fence lizards and is also the author/illustrator of a field guide to the Amphibians and Reptiles of Bidwell Park.
- Heyo Tjarks – Heyo is working on ecomorphology and sexual dimorphism in garter snakes using geometric morphometrics. He also sometimes jumps out of airplanes.
Past Undergrad Students:
- Rachel Bender – Rachel worked with Dave on the WPT project and on her own project looking at co-evolution of garter snakes and the toxic newts that some species prey upon.
- Kyle Kappenman – Kyle was a key element of Team Pond Turtle and is interested in all things herpetological
