Sex ratio variation in gynodioecious Lobelia siphilitica: effects of population size and geographic location.

Journal of evolutionary biology - 1 Jul 2007

Caruso C M, Case A L

Abstract excerpt

Variation in population sex ratio can be influenced by natural selection on alternate sex phenotypes as well as nonselective mechanisms, such as genetic drift and founder effects. If natural selection contributes to variation in population sex ratio, then sex ratio should covary with resource availability or herbivory. With nonselective mechanisms, sex ratio should covary with population size. We estimated sex...
