Systems Ecology Laboratory

The Systems Ecology Laboratory (SEL) is focused on understanding the biocomplexity associated with environmental change and plant and ecosystem structure and function in extreme environments – namely Arctic tundra and the Chihuahuan Desert. We use a variety of plant ecological and physiological methods in combination with aerial and satellite remote sensing and Geographic Information systems (GIS) to examine and model changes in plant and ecosystem structure and function over a range of spatial and temporal scales. The SEL is also committed to maintaining long term environmental observations and improving the capacity for cross disciplinary and international cooperation in monitoring the impacts of environmental change. To facilitate the latter we are partnered to several projects described below that are developing novel internet based portal, mapping and information management systems that facilitate access to distributed information systems.

The SEL has five primary research projects that are currently underway. Most projects are funded by the US National Science Foundation (NSF) and include:

  1. Biocomplexity associated with the response of arctic tundra carbon balance to warming and drying across multiple spatial and temporal scales. NSF Biocomplexity Program: –September 2004 – August 2007. PI’s: W.C. Oechel, J.S. Kimball and C.E. Tweedie. ($2,000,000 total, $205,121 UTEP).
  2. Rapid assessment of recent changes in land cover and carbon balance in Beringia. NSF OPP – Arctic Natural Sciences Program: March 2005 – February 2008. PI’s: P.J. Webber and C.E. Tweedie. ($452,263 total, $294,912 UTEP).
  3. Maintenance, development and Innovation of the Barrow Area Information Database and Internet Map Server (BAID-IMS). NSF OPP – Arctic Research Logistic Support Program: September 2005 – August 2008. PI’s: P.J. Webber, C.E. Tweedie and Allison Gaylord. ($465,914 total, $236,133 UTEP).
  4. Developing and implementing the Circum-arctic Environmental Observatories Network (CEON). NSF OPP – Arctic Research Logistic Support Program: March 2005 – February 2008. PI’s: P.J. Webber and C.E. Tweedie. ($749,981 total, $365,134 UTEP).
  5. Assessing the impact of land cover change on ecosystem structure and function in the Chihuahuan Desert. UTEP – Incentive award: June 2005 – June 2006. PI: C.E. Tweedie ($1000).
