Garth Spellman, PhD

As the Curator of Ornithology, Dr. Garth Spellman's research focuses on how recent and ancient environmental changes have affected bird species. Bird species are products of their environment and therefore are constantly evolving in response to environmental change. The response of a species to environmental change leaves lasting footprints in its DNA. Dr. Spellman uses genetic tools to examine “bird DNA footprints” and determine just how a species or multiple species that make up a modern community have responded to past environmental change.

CURRENT PROJECTS

This project examines how past climate change related to the Pleistocene glacial cycles affected biological and genetic diversity in North American birds.

This project investigates how genes move across or are prevented from moving across contact zones (zones where two species of bird come together and interbreed). Studying how these zones are maintained or disintegrate over time can tell us a lot about the evolutionary processes that promote species formation.
