Niche divergence of Abies grandis–Abies concolor hybrids
Plant Ecology, 2015Homoploid hybridization has increasingly been recognized as an important source of genetic variation to support adaptation to changing environmental conditions, the invasion of novel ecological niches and, ultimately, speciation. Although ecological selection pressures have been theorized to play a key role in the stabilization of homoploid hybrid ...
