Introductions of exotic pet reptiles and amphibians

Invasive reptiles and amphibians cause ecological, economic damage, and can even endanger human health. The most important pathway for non native reptiles and amphibians is the pet trade. I am currently investigating the factors that are associated with introductions species of reptiles and amphibians in the US, such as longevity and adult body size. 

Managing endangered prey: Predator Exclosures vs. Predator Control

Predation is considered one of the most important sources of mortality for the endangered piping plover. Currently, wildlife managers utilize both nest exclosures and lethal control of its main predator the red fox; however the extent to which these methods contribute to the viability of the plover is unknown.  Using a stochastic coupled predator-prey population viability analysis (PVA), I simulated these types of management and compared the final abundance and persistence of the piping plover. My work found that predator exclosures and lethal control independently contribute equally to the abundance of plovers. This knowledge can help managers of the piping plover decide which method to use when faced with ethical dilemmas and monetary restrictions.

I study how to stop animals from going to the wrong place in order to keep other animals safe and save people money. Some people own animals for fun and love. The problem is when these animals are let go outside. They can form groups of animals of the same kind and grow in number. They can then cause problems for other types of animals and for people. I study reasons why these animals are let go in order to stop it from happening.
