Our group investigates the ecological impacts of climate variability and climate change on ecosystems in the US desert southwest, tallgrass prairie in Kansas, and savanna grasslands in South Africa.

Congratulations to Lisa Garcia and Mariah Patton!

The reintroduction of bison at the Konza Prairie Biological station has resulted in a steady increase in native plant species richness, and this increase was resilient to an extreme drought. Cattle grazing also increased diversity, but not as much as bison and the grasslands were less resistant to drought. Here's the significance statement from the paper (https://doi.org/10.1073/pnas.2210433119):
