Rapid biological speciation driven by tectonic evolution in New Zealand [Nature geoscience]

Subject terms : biodiversity, geomorphology, tectonics

Collisions between tectonic plates lead to the rise of new mountain ranges that can separate biological populations and ultimately result in new species1. However, the identification of links between tectonic mountain-building and biological speciation is confounded by environmental and ecological factors2, 3, 4. Thus, there are surprisingly few well-documented examples of direct tectonic controls on terrestrial biological speciation. Here we present examples from New Zealand, where the rapid evolution of 18 species of freshwater fishes has resulted from parallel tectonic landscape evolution.(...)
