Research Spotlight


The Frank Lab studies and explores factors that regulate the structure, species composition, biodiversity and energy, and nutrient metabolisms in terrestrial ecosystems. The 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.
