Tom Morrison

 

Tom_Morrison_mugshot.jpgTom is a postdoctoral researcher, now studying savannah tree dynamics in Serengeti National Park, Tanzania with Michael Anderson of Wake Forest University. Tom recently finished a 2-year postdoc working with Matt Kauffman and the Wyoming Game and Fish Department, and got his PhD in the Ecology and Evolutionary Biology program at Dartmouth College. Prior to his PhD research, he spent a year studying elephant behavior and genetics in Amboseli National Park, Kenya as a field assistant for Beth Archie and Susan Alberts (Duke University). This project was in collaboration with the Amboseli Trust for Elephants, which is one of the longest continuous studies of a single wild population. Tom's Ph.D. dissertation, under Doug Bolger, examined patterns of spatial demography and site fidelity in a declining population of wildebeest in Northern Tanzania (the Tarangire Ecosystem, Tanzania). This ongoing project uses a non-invasive photographic identification software program (Wild-ID) developed at Dartmouth to individually identify wildebeest by their shoulder stripe patterns. In 2009, with support from WCS-Tarangire Elephant Project, he initiated a wildebeest GPS collaring effort to help characterize fine-scale movement patterns and larger-scale migratory pathways within the Tarangire Ecosystem. As a postdoc in Wyoming, Tom examined different approaches for collecting and modeling ungulate population monitoring data, in collaboration with the Wyoming Game and Fish Department.
