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.

Sonoran desert winter annuals respond to nitrogen addition and rainfall variability in preserves around Phoenix

Check out our recent paper in Ecological Monographs on Sonoran Desert annual plant communities. Here's the abstract:

Soil seed banks, alternative stable states and restoration ecology

Very happy to see our conceptual paper on soil seedbanks and restoration ecology within the context of alternative stable state theory published in BioScience. here's the abstract:

Our recent contribution to alternative stable state theory and hysteresis

Hysteresis is hard to demonstrate at realistic scales in terrestrial ecosystems. But fortunately, the NSF Long-term Ecological Research Program supports research, like that at Konza Prairie, that can be applied to challenging ecological theory. Here's the abstract from the paper published in Ecology Letters:
