Executive Summary

The Northern Great Plains Inventory & Monitoring Network (NGPN) was established to develop and provide scientifically credible information on the current status and long-term trends of the composition, structure, and function of ecosystems in thirteen parks located in five northern Great Plains states. NGPN identified upland plant communities, exotic plant early detection, and riparian lowland communities as vital signs that can be used to better understand the condition of terrestrial park ecosystems (Gitzen et al. 2010). Upland and riparian ecosystems are important targets for vegetation monitoring because the status and trends in plant communities provide critical insights into …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

We investigated magnetic susceptibility (MS) variations in hydrocarbon contaminated sediments. Our objective was to determine if MS can be used as an intrinsic bioremediation indicator due to the activity of iron-reducing bacteria. A contaminated and an uncontaminated core were retrieved from a site contaminated with crude oil near Bemidji, Minnesota and subsampled for MS measurements. The contaminated core revealed enriched MS zones within the hydrocarbon smear zone, which is related to iron-reduction coupled to oxidation of hydrocarbon compounds and the vadose zone, which is coincident with a zone of methane depletion suggesting aerobic or anaerobic oxidation of methane is coupled …


Homestead National Monument Of America, Geologic Resources Inventory Report, J. Graham Sep 2011

Homestead National Monument Of America, Geologic Resources Inventory Report, J. Graham

United States National Park Service: Publications

Executive Summary

This report accompanies the digital geologic map data for Homestead National Monument of America in Nebraska, produced by the Geologic Resources Division in collaboration with its partners. It contains information relevant to resource management and scientific research. This document incorporates preexisting geologic information and does not include new data or additional fieldwork.

Established as a memorial to pioneer life and the Homestead Act of 1862, Homestead National Monument of America preserves approximately 92 ha (228 acres) of terraced grassland and riparian, floodplain environments. Included in the monument are about 40 ha (100 acres) of restored tallgrass prairie and …

Executive Summary

Homestead National Monument (HOME) was created at the to celebrate the significance of the Homestead Act of 1862 which granted 160 acres of free land to claimants and was one of the most significant and enduring events in the westward expansion of the United States. The National Monument encompasses 184 acres in Gage County, west of Beatrice, Nebraska. This unique site also hosts the oldest prairie restoration in the National Park system, and the second-oldest tallgrass prairie restoration known. This park unit also has a small remnant of native tallgrass prairie and remnants of bur-oak forest.

Northern Great Plains Network (NGPN)

National maps of atmospheric sulfur (S) and nitrogen (N) emissions and deposition are provided in Maps A through D as context for subsequent network data presentations. Maps A and B show county level emissions of total S and total N for the year 2002. Maps C and D show total S and total N deposition, again for the year 2002.

There are three parks in the Northern Great Plains Network that are larger than 100 square miles: Badlands (BADL), Missouri (MNRR), and Theodore Roosevelt (THRO). In addition, there are 10 smaller parks.

Settlement And Growth Of Quagga Mussels (Dreissenia Rostriformis Bugensis Andrusov, 1897) In Lake Mead, Nevada-Arizona, Usa, Wai Hing Wong, Shawn Gerstenberger, Wen Baldwin, Bryan Moore

Environmental & Occupational Health Faculty Publications

Settlement and growth of quagga mussels Dreissena rostriformis bugensis were monitored in Lake Mead, NV, USA, where the first dreissenid occurrence was confirmed in the western United States. To measure the settlement rate of these invasive mussels, seven acrylonitrile butadiene styrene (ABS) pipes were attached to a line in shallow water (7.7 m below the surface) since November 23, 2007; eight ABS pipes were placed on another line in deep water (13.4 m below the surface) since January 3, 2008. Quagga mussels were sampled from these pipes on March 19, May 21, July 9, October 20, and December 19, 2008. …
