Thirty years of source-sink theory: From ecology to evolution

Sources and sinks arise from the interplay of spatial variation in demography, and movement among habitats.  A clear understanding of this demographic context is necessary  for analyzing many issues in evolutionary biology, such as habitat specialization and generalization, the evolution of host use by pathogens, and geographical range margins.  Theoretical population models for source-sink dynamics proposed several decades ago have provided a basic grounding for analyses of these evolutionary phenomena.  My ignite talk will touch on some key results from recent theory and point out directions for future research.
