RESEARCH OVERVIEW:

Spatial and temporal structuring of introduced plant species populations.

My research is focused on understanding spatial patterns in plant species distributions as well as spatial and temporal patterns in the spread of invasive species at multiple scales. One portion of my research concerns understanding species distributions at watershed scales to both understand landscape processes driving introduced plant species distributions and to develop tools for government agencies to aid in targeted management of plant species of ecological concern.

I am also studying the spatial age and genetic structure of a moderately long lived perennial species, Dalmatian toadflax. By looking at the spatial age structure of populations, we can begin to understand the recent history of these populations and infer landscape processes driving population dynamics and spatial spread. We are also trying to use spatial genetic information to study source/sink metapopulation dynamics. By elucidating the processes driving invasion, we can start to make better predictions about future distributions of these species. A more mechanistic understanding of the processes driving the spatial spread of introduced species can help inform management and develop novel methods of invasive species management.
