Landscape ecology of genetic and community diversity
Species reactions to climatic effects include shifts in geographical distributions, adaptation, or local extirpation if spatial environmental changes exceed ecological tolerances. Quantifying and spatially modelling population genetic structure in zooplankton meta-communities across northern landscapes will help us to determine the nature of adaptive responses to environmental change and improve our knowledge of the relationship between landscape-level diversity in populations and communities. My students and compare patterns in community and genetic diversity in zooplankton metacommunities across freshwater landscape gradients in carbon, nutrients and latitude within and among broad-scale northern regions of Canada.
