Premise Of The Study: Aspen groves along the Niobrara River in Nebraska have long been a biogeographic curiosity due to morphological differences from nearby remnantpopulations. Pleistocene hybridization betweenandhas been proposed, but the nearestpopulations are currently several hundred kilometers east. We tested the hybrid-origin hypothesis using genetic data and characterized putative hybrids phenotypically. Read More
