Two aspects of biological invasion, spread and long-term impacts, were investigated in the context of the Florida Everglades, an extensive wetland where ecological dynamics are driven by the influence of landscape structure on spatiotemporal patterns of drought. I used the relationship between marsh topography and complex, emergent patterns of water availability to predict extent, scale, and direction of non-native fish dispersal between natural and artificial habitats of the Everglades. Next, I used a twenty-year record of the relative abundances of native and non-native fishes to test whether or not non-natives have unbalanced the number of predators in this ecosystem.

Refreshments will be served.
