Welcome! Our research focuses on the impact of natural disturbances and global environmental change on mesic and arid grassland ecosystems. We are particularly interested in the interactive effects of fire, grazing and drought in mesic grasslands in North America and South Africa, and how rainfall variability, temperature change, and shrub encroachment affect aridland ecosystems in the southwestern US.

Rapid recovery of ecosystem function following extreme drought in a South African savanna grassland

Check out our recent paper in Ecology led by Kevin Wilcox on recovery of ANPP following extreme drought under different fire frequencies in Kruger Park, South Africa. Here's the abstract:

Sensitivity of primary production to precipitation across the United States

We are very pleased that our paper analyzing the sensitivity of aboveground net primary production to climate variation has been published in Ecology Letters. This work is the product of a Distributed Graduate Seminar sponsored by the DroughtNet RCN. We got reviewed and booted by three "high impact" journals and in each case the reviews were pretty lame and sometimes irrelevant, with no chance to respond. The Ecology Letters reviews were tough, thoughtful and challenging. They made this a better paper. Here's the abstract:
