Environmental complexity promotes biodiversity
Laxenburg, Austria (SPX) Sep 18, 2013
A new study published in the journal American Naturalist helps explain how spatial variation in natural environments helps spur evolution and give rise to biodiversity. The study, led by McGill University evolutionary biologist Ben Haller in collaboration with IIASA Evolution and Ecology Program Leader Ulf Dieckmann and IIASA researcher Rupert Mazzucco, suggests that a varied environment spurs the evolution of new species and promotes biodiversity by creating places of refuge-"refugia"-for new org ... read more
