Covarying variances: more morphologically variable populations also exhibit more diet variation.

Oecologia - 1 May 2015

Snowberg Lisa K, Hendrix Kimberly M, Bolnick Daniel I

Abstract excerpt

Many ecologically generalized populations are composed of relatively specialized individuals that selectively consume a subset of their population's diet, a phenomenon known as 'individual specialization'. The Niche Variation Hypothesis posits that this individual specialization can arise during ecological release if niche expansion occurs mainly through diet divergence among individuals, leading to greater...
