Segraves /faculty-experts/kari-a-segraves/ Thu, 23 Feb 2017 17:58:51 +0000 /?post_type=faculty-experts&p=115053 Dr. Kari Segraves is an evolutionary ecologist and researches how species interactions increase biodiversity. Understanding biodiversity requires more than identifying the number of species on earth and Dr. Segraves’ research examines how species interactions govern the dynamics of communities, ecosystems and species diversity. Her research and  uses a broad combination of approaches including experimental ecology, field observations, molecular phylogenetics and population genetics to understand the role that interspecific interactions play in creating diversity.

Frank /faculty-experts/douglas-a-frank/ Thu, 23 Feb 2017 17:12:29 +0000 /?post_type=faculty-experts&p=115042 Professor Frank studies and explores factors that regulate the structure, species composition, biodiversity and energy, and nutrient metabolisms in terrestrial ecosystems. Since 1988, he has researched the effects of grazing ungulates, such as elk, bison, and pronghorn, on the grasslands of Yellowstone National Park, which is home to highly coevolved plant-grazer-soil microbe systems.

He and his team investigate important interactions among these trophic levels, which, in turn, facilitate energy and nutrient flows in Yellowstone grasslands and foster stability of this ecosystem that experiences high chronic levels of grazing.

The Frank Lab utilizes field and laboratory experiments. In the field, he and his team erect ungulate enclosures to create an un-grazed treatment and then compare plant growth and soil processes in grazed versus un-grazed grasslands. In the lab, experiments are conducted in the greenhouse or environmental chambers to determine how mycorrhizae, nutrient availability, and soil microbial composition and diversity may mediate the effect of grazing on plant growth.
