The effect of the study region on GIS models of species geographic distributions and estimates of niche evolution; preliminary tests with montane rodents (genus Nephelomys) in Venezuela
Various niche-based techniques exist to model a species' potential geographic distribution in a Geographic Information Systems (GIS) framework. These models compare the environmental conditions of localities of a species' occurrence versus those of the overall study region. In addition to uses in …

Evolutionary perspectives on plant responses and sensitivity to environmental change
… change can shed light on the potential evolutionary outcomes and sensitivity of species to future environmental change. These processes are especially relevant to highly diverse, evolutionarily rich, and ecologically vulnerable alpine ecosystems. My PhD aims to narrow the uncertainty …
