Connectivity across land and seascapes

How do habitat landscapes affect movements of individuals and genes? Can we identify source populations and dispersal corridors in order to prioritize areas for conservation?

Biological invasions, historical and modern

What factors facilitate species expanding their ranges and colonizing new habitats? How do colonizing populations adapt to novel environments?

Speciation, hybridization, and the evolution of reproductive genes

Why are some types of genes more or less likely to be exchanged between populations and species? Why are reproductive genes under strong natural selection and does this contribute to reproductive isolation?
