My research interests focus on the agonistic (aggressive and submissive) behavior of reptiles and amphibians in relation to territorial defense and sexual selection.  I am also interested in behavioral and ecological responses of reptiles and amphibians to stochastic (random) environmental changes.


Current Projects

I have recently become interested in what males of the Plains clubtail dragonfly are doing hanging out along upland trails, apparently defending territories well away from their preferred breeding habitats.

Facultative parthenogenesis in copperheads (Agkistrodon contortrix) and garter snakes (Thamnophis sirtalis)

Visual communication in cricket frogs (Acris blanchardi)

The effects of chigger mite parasitism on behavior of collared lizards (Crotaphytus collaris) in tallgrass prairie.

Graduate Research Projects

Effects of fire interval on community and population structure of tallgrass prairie reptiles - with Masters' student Dustin Wilgers, who is currently working on a Ph.D. at the University of Nebraska

- Part of the Long-Term Ecological Research conducted at Konza Prairie Biological Station
