Biological invasions cause tremendous damage to ecosystems, economies, and human livelihoods worldwide. Florida is home to more established non-native species of reptiles and amphibians than anywhere else on Earth, many of which cause substantial harm to native biodiversity and human well-being. The relatively new discipline of invasion genetics promises to significantly improve the understanding, prediction, prevention, and management of biological invasions. The purpose of this dissertation is to utilize invasion genetics techniques to further understanding of the patterns and processes of biological invasions, especially as they pertain to Florida’s destructive and diverse non-native squamate reptile assemblage. In the first phase …

Biodiversity loss may serve as a key diagnostic of the Anthropocene. An important driver of this loss is by means of invasive species. In this study of a forest preserve in Chicago, Illinois we examined Interspersed Denuded Zones (IDZs for short), which are areas of patchy leaf litter in invaded forests caused in this case by the rapid decomposition of litter from buckthorn (Rhamnus cathartica). We characterized the leaf litter mass in IDZs and enumerated litter-inhabiting microarthropod populations. We found that plots of high buckthorn density are associated with IDZs: there was significantly less leaf litter mass in …
