A Report On Black-Tailed Prairie Dogs In Nebraska-- Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

The Viral Envelope Gene Is Involved In Macrophage Tropism Of A Human Immunodeficiency Virus Type 1 Strain Isolated From Brain Tissue, Zhen-Qian Lou, Charles Wood, Jay Levy, Cecilia Cheng-Mayer

Nebraska Center for Virology: Faculty Publications

Human immunodeficiency virus type 1 (HIV-1) strains isolated from the central nervous system (CNS) may represent a subgroup that displays a host cell tropism different from those isolated from peripheral blood and lymph nodes. One CNS-derived isolate, HIV-l_SFl28A, which can be propagated efficiently in primary macrophage culture but not in any T-cell lines, was molecularly cloned and characterized. Recombinant viruses between HIV-l_SF128A and the peripheral blood isolate HIV-l_SF2 were generated in order to map the viral gene(s) responsible for the macrophage tropism. The env gene sequences of the two isolates are about 91.1% homologous, with variations …

Effects Of Errors In Pedigree On Three Methods Of Estimating Breeding Value For Litter Size, Backfat And Average Daily Gain In Swine, T. E. Long, R. K. Johnson, J. W. Keele

Department of Animal Science: Faculty Publications

Estimated breeding value (EBV) was calculated based on either individual phenotype (SP), an index of individual phenotype and full- and half-sib family averages (SI) or Best Linear Unbiased Prediction (BLUP). Calculations were done with correct data or data with 5, 10, 15 or 20% of the records per generation containing pedigree errors. Traits considered were litter size (LS), backfat (BF) and average daily gain (ADG). When data were correct, BLUP resulted in an advantage in expected genetic gain over SP of 22, 7.2 or 30.8% for LS, BF and ADG, respectively, and over SI of 9.6, 3.8 or 21.4%. When …

Long Term Management Measures For The Cockburn Sound Restricted Entry Fisheries., P. Millington

Fisheries management papers

The objective of this management plan is to introduce rules which will ensure there is a real reduction in professional fishing units and fishing effort in the medium to long term. This reduction should enable a small professional fishery to co-exist with the recreational sector, supply fresh fish to the metropolitan area, ensuring there is no proliferation of "shamateur fishing" and providing a supply of recreational angling bait.

Livestock Budgets And Whole-Farm Economic Analysis: South Dakota Sustainable Agriculture Case Farms, Donald Taylor, Clarence Mends, Thomas L. Dobbs

Economics Research Reports

In this report, livestock budgets for nine sustainable farmers in South Dakota who raise beef cattle and two of the same farmers who raise hogs are presented. Results of whole-farm economic analysis--in which the livestock, sustainable crop rotation, and non-sustainable rotation crop enterprise budgets on the respective farms are integrated with each other--are also presented. The final sections of the report cover results of analyses of (1) livestock price sensitivity and (2) on-farm manure production and disposition.

An Analysis Of Selected Policy Alternative For 1990 Farm Bill On South Dakota's Agriculture Sector, Bashir Qasmi

Economics Research Reports

As the congressional debate for the finalization of 1990 Farm Bill nears, the interest in analysis of the new farm bill is increasing. The continued large federal budget deficits, the GATT negotiations, and the increased momentum of conservation and environmental issues are all expected to exert influence in shaping the 1990 farm bill outcome. Practical options for a 1990 farm bill and its impacts for U.S. agriculture are discussed in Schnittker (1990), Westhoff, et al. (1990a), Westhoff, et al. (1990b) and Meyer (1990). These papers, however, analyze the impacts on a national level. With a recent trend of reducing government …

Implications Of A Mandatory Supply Control Program For Sustainable Agriculture In South Dakota, David Becker, Thomas L. Dobbs

Economics Research Reports

This is one of a series of reports by the authors on implications for "conventional" and "sustainable" farming systems of various public policy options. Previously released was a report by Dobbs, Becker, and Taylor (1990) which provided an overview of the implications of several policy options. The present report focuses specifically on mandatory supply controls. A future report will deal with the implications of flexibility and triple base policy options.

Lake Mead Nutrient Enhancement Project, Peter D. Vaux, Larry J. Paulson, Nevada Department Of Wildlife, National Oceanic And Atmospheric Administration

Publications (WR)

The Lake Mead Fertilization Project is a research program designed to investigate the potential for using large-scale artificial fertilization to enhance the game fisheries of this reservoir through an increase in the population of threadfin shad, the system's primary forage species. A substantial decline in the population of largemouth bass, together with poor condition of adult striped bass, are the two major issues affecting the Lake Mead game fisheries. Both issues have been hypothesized to be a result of an inadequate amount of forage in the reservoir. Previous studies have in turn suggested that a major factor limiting the shad …

Cytokeratin And Desmoplakin Analogues Within An Intracellular Parasite, Earl Weidner, Robin M. Overstreet, Bruce Tedeschi, John Fuseler

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

A significant amount of the total protein in the spore sacs of the microsporidian Thelohania sp. consisted of the cytoskeletal elements, cytokeratin intermediate filaments, and the desmosomal analogues. The cytokeratin and desmosomal analogues were organized as cage envelopes surrounding the spores within the spore sac stage. Thelohania sp. parasitizes the skeletal muscle of Callinectes sapidus, a crustacean that does not appear to have cytokeratins or desmosomes. Immunoprobe data indicate Thelohania sp. has a 240 kDa desmoplakin protein and 48, 51, 54 and 56 kDa cytokeratin polypeptides responsive to antibodies developed against bovine cytoskeletal counterparts. The cytoskeletal envelopes within the …

Habitat Requirements For The Softshell Clam, Mya Arenaria In The Chesapeake Bay, Patrick Baker, Roger L. Mann

Reports

Large populations of softshell clams persist only in relatively shallow, sandy. mesohaline portions of Chesapeake Bay. These areas are mostly in Maryland, but can also occur in the Rappahannock River. Virginia. In some other portions of the bay, especially polyhaline portions. sparse populations of soft shell clams persist subtidally. Restricted populations exist intertidally.

Softshell clams grow rapidly in Chesapeake Bay, reaching commercial size in two years or less. They reproduce twice per year, in spring and fall, but probably only fall spawnings are important in maintaining population levels. Major recruitment events do not occur in most years. despite heavy annual …

Nebraska Bird Review

1990 FALL FIELD DAYS

The registration for the1990 Fall Field Days, held 7 to 9 September at the 4-H Camp in the National Forest near Halsey, was 57. The weather was clear, in the 80's during the day, but cool nights, and even during the day the Lodge was pleasant because of the ventilation and the fans. Friday night there was a slide show, Saturday night Gerry Toll told about the Peregrine Falcon project in Omaha, with slides. Mrs. Green banded birds, as usual, showing interesting specimens to those who were near. On Saturday some took a canoe trip down …

Laughing Gull In Cedar County, Nebraska, Mark A. Brogie

Nebraska Bird Review

Laughing Gull in Cedar County, Nebraska

Johnsgard's (1986) A Revised List of the Birds of Nebraska and Adjacent States considers the Laughing Gull (Larus atricilia) an extremely rare vagrant in Nebraska. Bray, Padelford, and Silcock (1986), in The Birds of Nebraska: a Critically Evaluated List, consider this species as accidental, with only one of 13 records accepted - the description of a specimen of one taken 2 April 1915 at Inland, Clay Co. This specimen was once in the Hastings Municipal Museum, but was sold and its current location is unknown.

Significant (?) Modifications In Bird Sightings At Wolff Lake (Fall 1979 To Spring 1990), Thomas A. Hoffman

Nebraska Bird Review

One of the problems of having a computer handy is that you begin to start organizing your notes. Recently I began to organize the notes I had taken since 1979 for the Nebraska Bird Review's semi- annual occurrence reports. Partly I wanted to verify my suspicions about variation in the occurrence of several species during that period of time. I try to visit the area called Wolff Lake (a sand-arid-gravel operation on the south side of the Platte River in northwestern Saunders Co. each weekend. But there are many variations, and there are periods of prolonged absences. I average about …

"Notes," From Nebraska Bird Review (December 1990)

Nebraska Bird Review

THE TABLES FOR THE 1990 SPRING OCCURRENCE REPORT were poorly printed, for unexplained reasons. The tables did not match across the "gutter"; it will help to draw a line from the first line on one page to the first line on the facing page, and then draw a line across for every third line. That way, the line for each species will either have a line across, or be just above or just below one. The headings for the left-hand pages after page 60 were omitted. The headings for pages 58 and 60 are correct for the rest of the …

A Linear Analysis Of Equatorial Atlantic Ocean Thermocline Variability, Robert H. Weisberg, T. Y. Tang

Marine Science Faculty Publications

Observed variations in the Atlantic Ocean's equatorial thermocline are compared at four locations with simultations using an analytical reduced-gravity model. The comparison shows the essential features of the seasonal wind-forced thermocline response to be accounted for by a linear superposition of equatorial long waves, evolving basinwide, tending to bring the zonal pressure gradient into balance with the wind stress. A frequency response function is derived whose properties provide a basis for discussing the large scale features of the equatorial Atlantic Ocean's seasonal cycle-for example, its evolution along the equator, the maximum upwelling region observed in the Gulf of Guinea and …

Mountain Plover Sighted In Kimball County, Mary Clausen

Nebraska Bird Review

In late April of 1990 I went to Kimball Co. to search for Mountain Plovers. Over a period of a week I walked several sections where Mountain Plovers have been sighted in the past. No Plovers were found at that time.

After I returned to my office in Lincoln, Fritz Knopf (Avian Studies Biologist, U.S. Fish and Wildlife Service, Colorado) contacted me to discuss Mountain Plover nesting habitat and behavior. Fritz offered to make a quick drive around Kimball Co. to see how the habitat in Nebraska compared to that used by nesting Mountain Plovers in Colorado.
