Responses of Sagebrush-Steppe Ecosystems
to a Changing Climate
salmon river room
Monday
1:30 p.m. – 4:50 p.m.
Program organizers: Kevin P. Feris and Marie-Anne de
Graaff (Department of Biology, Boise State University).
Program sponsored by the Pacific Division section on Ecology,
Organismal Biology, and Environmental Sciences.
Semi-arid and arid ecosystems cover approximately 53,000
km 2 of land, estimated to be more than 35% of Earth’s land
surface and equivalent of the areas of North America, South
America, Europe, and Australia combined (McGinnies et
al. 1968). Additionally, these ecosystems are estimated to
contain 33% of above and below ground terrestrial carbon
reserves (Stone et al., 2008). In the U.S., semi-arid ecosystems
comprise over 60 million hectares in land mass (West
and Young, 2000). Given the large spatial extent of these
ecosystems, small changes in biogeochemical cycling under
climate change may have large ramifications for global carbon
budgets.
Current rapid increases in greenhouse gas emissions
are expected to lead to warming and altered precipitation
regimes in the semi-arid ecosystems of the Intermountain
West (IPCC, 2007). These changes will alter the pool of terrestrial
soil carbon by changing the decomposition rates of
soil organic matter (SOM) (Davidson and Janssens et al.,
2006).
This session will explore the intricate and interactive
responses of semi-arid sagebrush-steppe ecosystems to
changes in climate forcing factors.
