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.

Check out these two recent publications on drivers and indicators of state change and recovery. This is pretty interesting. Although the models and empirical data are mostly from mesic systems, these ideas definitely apply to aridland systems as well.

Here's a cool summary of our ~10 years of research comparing a tallgrass prairie in North America (Konza) to grasslands in South Africa (Kruger Park and Ukulinga Research Farm). Check it out in BioScience (Smith et al. 2016). The abstract says:
