Ecological Speciation - Nosil, Patrik (Department of Ecology and Evolution, University of Colorado, Boulder, USA)

The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10 - 15 years, and a review and synthesis of the theoretical and empirical literature is now timely.
