NDLI: Energy flow and functional compensation in Great Basin small mammals under natural and anthropogenic environmental change

Abstract	Small mammals play a critical role in the maintenance of desert ecosystems. Using Quaternary fossils from the Great Basin, we show that energy flow through a small mammal community during today’s heightened climate warming differs from that experienced during natural rapid warming in the past. This discrepancy highlights a modern breakdown in energetic compensation among functional groups, and stresses the importance of novel anthropogenic impacts, such as the replacement of shrublands by invasive annual grasses introduced to North American deserts more than a century ago. Use of the fossil record to untangle the effects of climate and anthropogenic habitat change on ecosystem function today is thus critical for understanding how ecosystems will respond to future environmental change.
