| Abstract: |
| The varied topography and large elevation gradients that characterize the arid and
semi-arid Southwest create a wide range of climatic conditions - and associated biomes
- within relatively short distances. This creates an ideal experimental system in
which to study the effects of climate on ecosystems. Such studies are critical givien
that the Southwestern U.S. has already experienced changes in climate that have altered
precipitation patterns (Mote et al. 2005), and stands to experience dramatic climate
change in the coming decades (Seager et al. 2007; Ting et al. 2007). Climate models
currently predict an imminent transition to a warmer, more arid climate in the Southwest
(Seager et al. 2007; Ting et al. 2007). Thus, high elevation ecosystems, which currently
experience relatively cool and mesic climates, will likely resemble their lower elevation
counterparts, which experience a hotter and drier climate. In order to predict regional
changes in carbon storage, hydrologic partitioning and water resources in response
to these potential shifts, it is critical to understand how both temperature and soil
moisture affect processes such as evaportranspiration (ET), total carbon uptake through
gross primary production (GPP), ecosystem respiration (Reco), and net ecosystem exchange
of carbon, water and energy across elevational gradients.We are using a sequence of
six widespread biomes along an elevational gradient in New Mexico -- ranging from
hot, arid ecosystems at low elevations to cool, mesic ecosystems at high elevation
to test specific hypotheses related to how climatic controls over ecosystem processes
change across this gradient. We have an eddy covariance tower and associated meteorological
instruments in each biome which we are using to directly measure the exchange of carbon,
water and energy between the ecosystem and the atmosphere. This gradient offers us
a unique opportunity to test the interactive effects of temperature and soil moisture
on ecosystem processes, as temperature decreases and soil moisture increases markedly
along the gradient and varies through time within sites.Data for this project can
