Genetic drift opposes mutualism during spatial population expansion.

Proceedings of the National Academy of Sciences of the United States of America - 21 Jan 2014

Müller Melanie J I, Neugeboren Beverly I, Nelson David R, Murray Andrew W

Abstract excerpt

Mutualistic interactions benefit both partners, promoting coexistence and genetic diversity. Spatial structure can promote cooperation, but spatial expansions may also make it hard for mutualistic partners to stay together, because genetic drift at the expansion front creates regions of low genetic and species diversity. To explore the antagonism between mutualism and genetic drift, we grew cross-feeding strains...
