| ecological divergence in the yellow-bellied kingsnake (lampropeltis calligaster) at two north american biodiversity hotspots. | several biogeographic barriers in the eastern nearctic appear to reduce gene flow among populations of many species in predictable ways, however these patterns used to infer process of divergence may be deceiving if alternative modes of diversification are not considered. by using a multilocus statistical phylogeographic approach to examine diversity within a north american snake, lampropeltis calligaster, we find that mode and timing of speciation near the mississippi river embayment and penins ... | 2017 | 27637990 |
