My work focuses on conserving and protecting natural resources. This involves partnering with other agencies and groups to coordinate and implement actions to help recover imperiled species. A large part of what I do also entails conducting environmental reviews and working with project proponents to conserve wildlife while accomplishing project objectives. While I work with a variety of species, my primary interest is the conservation of amphibians and reptiles.
Decisions affecting wildlife management and conservation policy of imperiled species are often aided by population models. Reliable population models require accurate estimates of vital rates and an understanding of how vital rates vary geographically. The eastern massasauga (Sistrurus catenatus catenatus) is a rattlesnake species found in the Grea...
The massasauga (Sistrurus catenatus) has drastically declined throughout its range mainly due to habitat loss and human persecution. Populations of the massasauga that occur north and east of the Missouri River, USA, are currently candidates for listing under the United States Endangered Species Act. In areas where land managers wish to improve hab...
Limited evidence in the literature suggests that the assumption of equal catchability in mark-recapture studies of turtles may be invalid. These papers suggest that turtles may alter their behavior to avoid recapture following initial handling. If turtles are less likely to be recaptured following initial capture and handling, then population model...
