FORA.tv Speaker - Elizabeth Hadly
Elizabeth Hadly is Associate Professor, Department of Biological Sciences and Departmen of Geology and Environmental Sciences, Stanford University.
The research of Elizabeth Hadly probes how perturbations such as climatic change influence the evolution and ecology of Neogene vertebrates. She uses a combined field and laboratory approach to examine how ecological perturbations link or decouple levels of biological organization, because understanding the links among ecosystems, species, populations and genes is central to understanding how organisms exist, evolve and become extinct. She addresses problems in organismal biology from both evolutionary and ecological perspectives, primarily using extant mammals. One of the unique aspects of her overall approach is the focus on the decadal to millennial time scale, a scale that is little studied, although it is a scale that is integral to understanding links between ecology and evolution.
Professor Hadlyâ€™s field research involves excavation of finely stratified Holocene paleontological sites and collection of modern specimens in western North America and Patagonia. Construction of a state-of-the-art ancient DNA laboratory has made possible the study of genetic structure of populations through time. Laboratory work includes morphometric and molecular analyses with the intent to extend the level of investigation down to the population and genetic levels. Ongoing projects at the macroecological scale include the study of the ecological and evolutionary factors influencing biological diversity through a comparison of temperate terrestrial vertebrate faunas in North and South America.
