Stochastic eco-evolutionary dynamics of multivariate traits: A framework for modeling population processes illustrated by the study of drifting G-matrices.

Abstract excerpt

I derive a novel stochastic equation for the evolution of the additive genetic variance-covariance matrix G in response to mutation, selection, drift, and fluctuating population size. Common wisdom holds that the effect of drift on G is simply to reduce each of its entries by a common proportional amount while preserving its orientation. In contrast, I find that drift causes significant and directional shifts in...
