UW Botany research findings published in PNAS

Botany department's research scientist Jane Zelikova and professors Dave Williams and Elise Pendall along with scientists from the US Department of Agriculture (USDA) studied the effect of elevated CO2 and warming on grassland vegetation which will provide insights that Wyoming ranchers and land managers need to make grassland ecosystems more resistant to wide fluctuations in rainfall and temperatures. Under elevated atmospheric CO2 concentrations, they found that "grasslands changed from being dominated by two very common species now (western wheatgrass, an intermediate grass, and blue grama, a short grass) toward other gramonoids and forbs that aren't as dominant now".  These findings, commented Dave Williams, "will help us refine models used to predict how our grasslands will function and function 100 years from now".
