SGS-LTER CO2 Elevation Study: Weights of roots from Open Top Chamber root coring on the Central Plains Experimental Range, Nunn, Colorado, USA 1997 - 2001

dataset
posted on 2023-11-30, 10:21 authored by Jack Morgan

This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. Additional information and referenced materials can be found: http://hdl.handle.net/10217/82454. At the end of the 5-year OTC study, root cores were taken from ambient and elevated-CO2-chambered plots and unchambered controls and sectioned at 10cm intervals for root scanning and weighing. There was a trend for higher root weight under elevated CO2, which corresponded to greater root length, but only in the 0-10cm depth interval. This research was conducted at the Central Plains Experimental Range, near Nunn, CO; lat.40degrees 40 minutes N; long. 104 degrees 45 minutes W in the shortgrass steppe region of NE Colorado, USA and as a collaboration between SGS-LTER and USDA-ARS researchers.

Significant funding for these data was provided by the National Science Foundation Long Term Ecological Research program (NSF Grant Number DEB-1027319). The SGS-LTER project (1980-2014) was established as one of the first sites in the US LTER Network and has produce a rich legacy of digital materials including reports, proposals, images, and data packages. Data, products and other information produced from the SGS-LTER are curated as a collection within the Digital Collections of Colorado ().

Geographic location - description

The Short Grass Steppe Site Encompasses A Large Portion Of The Colorado Piedmont Section Of The Western Great Plains. The Extent Is Defined As The Boundaries Of The Central Plains Experimental Range (cper). The Cper Has A Single Ownership And Landuse (livestock Grazing). The Png Is Characterized By A Mosaic Of Ownership And Land Use. Ownership Includes Federal, State Or Private And Land Use Consists Of Livestock Grazing Or Row-crops. There Are Ngo Conservation Groups That Exert Influence Over The Area, Particularly On Federal Lands.
