Rapid Response Of A Grassland Ecosystem To An Experimental Manipulation Of A Keystone Rodent And Domestic Livestock, Ed Frederickson
Rapid Response Of A Grassland Ecosystem To An Experimental Manipulation Of A Keystone Rodent And Domestic Livestock, Ed Frederickson
Ed L. Frederickson
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 relationships between cattle and prairie dogs and their independent and interactive effects is essential to understanding the ecology and important conservation issues affecting North American grassland ecosystems. To address these needs, we established …
