rapid response of a grassland ecosystem to an experimental manipulation of a keystone rodent and domestic livestock.	megaherbivores and small burrowing mammals commonly coexist and play important functional roles in grassland ecosystems worldwide. the interactive effects of these two functional groups of herbivores in shaping the structure and function of grassland ecosystems are poorly understood. in north america's central grasslands, domestic cattle (bos taurus) have supplanted bison (bison bison), and now coexist with prairie dogs (cynomys spp.), a keystone burrowing rodent. understanding the ecological re ...	2010	21141180
