SGS-LTER 1998 supplemental proposal
Shortgrass Steppe Long Term Ecological Research (SGS-LTER), author
The Shortgrass Steppe Long Term Ecological Research (SGS LTER) project occupies an important position among LTER sites. The SGS lies at the western end of the east-west grassland productivity gradient and the northern end of the north-south semi-arid grassland gradient (SGS, Sevilleta, Jornada). This position allows us to evaluate ecosystem properties and processes between the SGS and other sites on these two gradients. In this supplemental proposal, we propose to initiate collaborative efforts across LTER projects and sites by conducting integrated field and laboratory studies that cross precipitation (an east-west transect between SGS and Konza) and temperature gradients (a north-south transect between SGS and Sevilleta). These two transects will allow us to integrate knowledge of ecosystem processes by assessing systematic variations in biotic and abiotic properties across these climatic gradients. The proposed transect studies involve a collaborative project with the Konza LTER group, a collaborative effort with the Sevilleta project, and a pilot study to develop methodologies for study of terrestrial weathering and biogeochemical cycles across the two climatic gradients. In addition to these transect studies, we are requesting funds for a replacement site vehicle.
The SGS-LTER research site was established in 1980 by researchers at Colorado State University as part of a network of long-term research sites within the US LTER Network, supported by the National Science Foundation. Scientists within the Natural Resource Ecology Lab, Department of Forest and Rangeland Stewardship, Department of Soil and Crop Sciences, and Biology Department at CSU, California State Fullerton, USDA Agricultural Research Service, University of Northern Colorado, and the University of Wyoming, among others, have contributed to our understanding of the structure and functions of the shortgrass steppe and other diverse ecosystems across the network while maintaining a common mission and sharing expertise, data and infrastructure.
