Abstract Details

2008, Master of Science (MS), Ohio University, Geological Sciences (Arts and Sciences).
The biogeography and evolution of the subfamily Equinae is examined using two separate but related analyses, phylogenetic biogeography and ecological niche modeling. The evolution of Equinae is a classic example of an adaptive radiation during a time of environmental change. Both analyses employed here examine the biogeography of the equine species to interpret how environmental and historical variables led to the rise and fall of this clade. Results determine climate change is the primary factor driving the radiation of Equinae and geodispersal is the dominant mode of speciation between regions of North America. A case study in the Great Plains indicates distributional patterns are more patchy during the middle Miocene when speciation rates are high than in the late Miocene, when the clade is in decline. Statistical results and distributional patterns show equine species tracked their preferred habitat throughout North America as climate changed in the Miocene.
