Thesis: Factors limiting dispersal of an alien crayfish. May 2003. My dissertation research focuses on understanding the influences pesticides have on ecologically important behaviors, particularly in amphibians. I study the relative impacts of low pesticide concentrations on predators and prey and possible influences on declining amphibian populations throughout California. I have found significant behavioral alterations in predator-prey interactions between two species of frogs (Hyla regilla and Rana boylii) with crayfish and fish predators. I have recently finished an experiment also examining the effects of pesticide on algal consumption. I am also involved in several different projects involving research on invasive crayfish. Our Sea grant project investigates the factors influencing the spread and impact of two species of non-native crayfish (Procambarus clarkii and Pascifasticus leniusculus). In conjunction with Lee Kats and Pepperdine University, I am also currently involved in a restoration project to attempt removal of crayfish from a southern California coastal stream.
I received the Environmental Protection Agency STAR fellowship. Click here to read my proposal. |
