Average Well Color Development (AWCD) data based on Community Level Physiological Profiling (CLPP) of soil samples from 120 point locations within limestone cedar glades at Stones River National Battlefield near Murfreesboro, Tennessee This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset contains information on soil microbial metabolic response for soil samples obtained from certain quadrat locations (points) within 12 selected cedar glades. This information derives from substrate utilization profiles based on Biolog EcoPlates (Biolog, Inc., Hayward, CA, USA) which were inoculated with soil slurries containing the entire microbial community present in each soil sample. EcoPlates contain 31 sole-carbon substrates (present in triplicate on each plate) and one blank (control) well. Once the microbial community from a soil sample is inoculated onto...

Soil respiration data for 120 point locations within limestone cedar glades at Stones River National Battlefield near Murfreesboro, Tennessee This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset contains measurements of soil respiration at certain quadrat locations (points) within 12 selected cedar glades. Field measurements were made of soil respiration (carbon dioxide efflux) using a LICOR Infrared Gas Analyzer (IRGA), LI-6400 XT portable photosynthesis device (LICOR Inc., Lincoln, NE, USA), fitted with a soil-chamber attachment. At least 48 hours prior to soil respiration measurement, three soil collars (plastic rings of approximately 2 inches depth) were inserted into the soil surface at each point and the height of each soil collar above the soil...

Volumetric soil water content measured by thermogravimetric analysis (oven drying) for 120 point locations within limestone cedar glades at Stones River National Battlefield near Murfreesboro, Tennessee This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset contains measurements of volumetric soil water content at certain quadrat locations (points) within 12 selected cedar glades. All soil water content measurements in this file were performed by thermogravimetric analysis (oven-drying) using the following procedure. First, soil samples were obtained using a brass cylinder of height 5 centimeters (cm) and interior diameter 4.9 cm. The cylinder was partially inserted into the soil, using a hammer if necessary, to a depth of roughly 2 to 3 cm. Soil adjacent to the inserted cylinder was removed and a flat plastic spatula...

Soil pH data for 120 point locations within limestone cedar glades at Stones River National Battlefield near Murfreesboro, Tennessee This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset contains measurements of soil pH at certain quadrat locations (points) within 12 selected cedar glades. These measurements were obtained according to the following protocol: (1) for each quadrat location (point), one soil sample was obtained under sterile conditions, using a trowel wiped with methanol and rinsed with distilled water, and was placed into an autoclaved jar with a tight-fitting lid and placed on ice, (2) soil samples were transported to lab facilities on ice and immediately refrigerated, (3) soil samples were transferred to clean aluminum trays and...

Soil nitrate data for 120 point locations within limestone cedar glades at Stones River National Battlefield near Murfreesboro, Tennessee This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset contains measurements of soil nitrate (parts per million) at certain quadrat locations (points) within 12 selected cedar glades. These measurements were obtained according to the following protocol: (1) for each quadrat location (point), one soil sample was obtained under sterile conditions, using a trowel wiped with methanol and rinsed with distilled water, and was placed into an autoclaved jar with a tight-fitting lid and placed on ice, (2) soil samples were transported to lab facilities on ice and immediately refrigerated, (3) soil samples were transferred to...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
