Local adaptation to the environment drives genetic variation among populations of an herbaceous plant.

Understanding the mechanisms responsible for genetic variation within species is an important topic in ecology and evolution. One mechanism that may drive genetic variation within species is adaptation to environmental conditions. As a first step toward understanding this topic, we examined genetic variation in populations of the herbaceous plant Tephrosia virginiana (Fabaceae). We selected populations from different ecoregions that are delimited in part by differences in climate and soils. If local adaptation is promoting genetic differentiation, variation among populations in different ecoregions will be greater than variation between populations within ecoregions. Our results show that genetic variation among populations of Tephrosia virginiana does mirror ecoregion geography suggesting that local adaptation to the environment promotes genetic differentiation within this species.
