Abstract
“Macroecology and the geography of micro-evolution” shifts the focus from macroevolutionary patterns in species richness to micro-evolutionary patterns of biogeographic variation within species. These patterns are driven by natural selection and adaptation, which in turn are driven by variation in environmental characteristics among regions and across the geographic template. How do physiological, behavioral, and ecological traits of species vary across their regional populations? Exotic, insular life forms, shaped by their island homelands void of mammalian competitors and predators, often suffered extinctions after colonization by humans and their many commensal species.
