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.

Mechanisms of shrub encroachment under climate and land use change investigated using a cellular automata model

Here's a cool approach to modeling shrub encroachment by creosotebush. Further encroachment is likely under future climate scenaarios. Here's the abstract:

Tallgrass prairie is relatively resistant to increased precipitation variability

Three Cheers for Syd Jones! Chapter 1 of her PhD dissertation has just been published in Scientific Reports. Here's the abstract:

Research Day

Another great Research Day in the Biology Department at UNM. Congratulations to Renee Brown for winning best undergraduate poster for her presentation on her Senior Thesis, "Soil Nitrogen Availability Following Rainfall Pulses in a Desert Grassland During the Summer Monsoon." Additional congratulations go to Amy Bennett for her 3rd Place grad student poster, "Examinging Patterns in Precipitation Pulses and Carbon Fluxes." Three cheers for Renee and Amy, and all the other participants.
