Intermediate Rings Between A Local Domain And Its Completion, Ii, William Heinzer, Christel Rotthaus, Sylvia Wiegand
Intermediate Rings Between A Local Domain And Its Completion, Ii, William Heinzer, Christel Rotthaus, Sylvia Wiegand
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
We present results connecting flatness of extension rings to the Noetherian property for certain intermediate rings between an excellent normal local domain and its completion. We consider conditions for these rings to have Cohen-Macaulay formal fibers. We also present several examples illustrating these results.

Escherichia Coli O157:H7 In Free-Ranging Deer In Nebraska, David G. Renter, Jan M. Sargeant, Scott E. Hygnstrom, Jeff D. Hoffmann, Jerry R. Gillespie
School of Natural Resources: Faculty Publications
In order to determine the prevalence and distribution of the human pathogen, Escherichia coli O157:H7, in free-ranging deer, hunters were asked to collect and submit fecal samples from deer harvested during a regular firearm season (14–22 November 1998). Prior to the season, 47% of the hunters with permits in the southeastern Nebraska (USA) study area indicated a willingness to participate in the study. Approximately 25% of successful hunters in the area submitted deer fecal samples. Escherichia coli O157:H7 was cultured from four (0.25%) of 1,608 total samples submitted. All of the fecal samples that were properly identified (1,426) and all …

Remote Estimation Of Vegetation Fraction In Corn Canopies, D. Rundquist, Anatoly A. Gitelson, D. Derry, J. Ramirez, R. Stark, Galina P. Keydan
School of Natural Resources: Faculty Publications
The aim of the paper was to test two new techniques that make use of channels in the visible range of the spectrum only to estimate vegetation fraction in corn canopies. High spectral resolution radiometers were employed to measure spectral reflectance, and the information content of spectra was investigated. Radiances in spectral channels of MODIS and MERIS were used to calculate Visible Atmospherically Resistant Indices, VARIgreen=(Rgreen- Rred)/(Rgreen+Rred-Rblue) and VARI700=(R700-1.7*Rred+0.7*Rblue)/(R700+2.3*Rred-1.3*Rblue). The indices allowed for estimation …

Yellow Jackets (Vespula Spp.) Disperse Trillium (Spp.) Seeds In Eastern North America, Jennifer A. Zettler, Timonthy P. Spira, Craig R. Allen
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Approximately 70 plant families worldwide have ant-dispersed seeds (myrmecochory). In this putative ant-plant mutualism, ants are attracted to and disperse seeds that have a lipid-rich elaiosome. We observed yellow jackets (Vespula spp.) dispersing seeds of three elaiosome-bearing species-Trillium cuneatum, T. undulatum and T catesbaei-in the Blue Ridge Mountains of North Carolina and South Carolina. Moreover, we estimated the mean distance yellow jackets dispersed seeds of T. cuneatum by placing intact fruits on index cards and recovering dispersed seeds on sheets placed on the ground surface. Of the seeds presented, 41% were recovered and the average dispersal distance …

Inventory Of Parks Division Lands For Threatened And Endangered Species Habitats And Exemplary Natural Communities, Steven B. Rolfsmeier
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The Nebraska Natural Heritage Program is responsible for environmental review of state projects, including those on Parks division properties, to determine if they may impact state-listed threatened and endangered species. In addition, the Program maintains a statewide database on natural communities and rare and imperiled species. This information is used to inform conservation decision-making, including land management decisions, with a goal of conserving Nebraska’s flora and fauna, our natural legacy. The two main objectives of this inventory project were first to improve the Nebraska Game and Parks Commission’s knowledge of threatened and endangered species and their potential habitat on Parks …
Composting Of Feedlot And Dairy Manure: Compost Characteristics And Impact On Crop Yields, Galen E. Erickson, Terry J. Klopfenstein, Walker Luedtke, Mark Schroeder, Charles A. Francis, Gary Lesoing
Composting Of Feedlot And Dairy Manure: Compost Characteristics And Impact On Crop Yields, Galen E. Erickson, Terry J. Klopfenstein, Walker Luedtke, Mark Schroeder, Charles A. Francis, Gary Lesoing
Nebraska Beef Cattle Reports
Since 1993, approximately 17,600 tons of beef feedlot and dairy compost have been spread on 1,100 acres. Crop yields were measured to determine the impact of a one-time compost application by using no-compost check strips in large-scale production fields. Adding compost to irrigated corn, irrigated soybeans, and dryland corn acres significantly increased yields, with four-year average increases of 2.3, 1.5, and 2.7%, respectively. For all crops measured, the response to compost was greatest the first year following application and declined linearly in subsequent years. The increased yield from compost application offsets spreading costs using average prices for crops.
