Biology faculty candidate to present seminar Ana Davidson will present a seminar titled "Interactive Effects of Small and Large Herbivores on the Structure of Grassland Ecosystems" at noon Friday, Dec. 11, in 141 Starcher Hall. Davidson received her Ph.D. from the University of New Mexico in 2005, working on the effects of keystone rodents and mammalian herbivores on grassland community structure and biodiversity. She has conducted field-based experiments at the Sevilleta National Grassland Refuge, an NSF-funded long-term research site in New Mexico, as well as at the Janos Biosphere Reserve in northern Mexico. She also works on global-scale questions using large scale bioinformatics databases to address extinction risk in mammals. Davidson is currently a postdoctoral NSF International Research Fellow and a candidate for the Grassland Ecology/Wildlife Biology faculty position in Biology at UND. -- Robert Newman, associate professor & Search Committee chair, Biology, robert.newman@und.edu, 777-4290
