1998 Midwinter Eagle Survey For Nebraska Including Summary Tables For The 1980-1998 Period From The Nebraska Game And Parks Commission, John J. Dinan

Nebraska Bird Review

Mild temperatures were prevalent in the weeks prior to this year's survey; however, temperatures cold enough to form a thin layer of ice on some reservoirs and lakes occurred between aerial surveys. Three of the aerial surveys were conducted on the 6th and 7th of January and one was conducted on the 13th. The survey route that includes the Platte River from Kearney to Plattsmouth and the Loup River was not surveyed this year because of persistent foggy conditions.

Temperatures recorded during the 1998 survey were variable, ranging from 5 to 40 degrees F. The Niobrara River was 50 to …

Book Review: Baby Bird Portraits By George Miksch Sutton: Watercoiors In The Field Museum By Johnsgard, P. A. (1998), John J. Janovy Jr.

Nebraska Bird Review

George M. Sutton's baby bird portraits are his most captivating works. The subjects are isolated against a stark, raw-paper background, and they stare out at the viewer with eyes typically naive but alert. Sutton's artistic mastery of the foot is integral to the underlying biology in these pictures: sturdy and sure against the table for a ruffed grouse, curled inward and near useless for a gallinule on dry land, and almost casually clutching a twig, the hallux resting loosely, for a newly fledged grosbeak. The match between these pictures and Paul Johnsgard's text is perfect. In his first two paragraphs, …

"A Half-Century Of Winter Bird Surveys At Lincoln And Scottsbluff, Nebraska", Paul A. Johnsgard

Nebraska Bird Review

Since 1900, the National Audubon Society has sponsored annual "Christmas bird counts" during the two-week period encompassing Christmas; and as a result, long-term data on winter bird populations have accumulated, especially for some locations. The first two such counts in Nebraska were made in 1909 and in 1912 in Lincoln. While similar counts were made in Omaha from 1909 to 1911, no further counts were conducted elsewhere in the state until the 1940's. Beginning in 1947 and continuing to the present, an unbroken series of counts were made in Lincoln, usually by members of the University Place Bird Club, the …

The Mortenson Ranch: Cattle And Trees At Home On The Range. A Restoration Guidebook, Susan E. Boettcher, W. Carter Johnson, Scott Kronberg, F. Robert Gartner, Clarence Todd, Jeff Mortenson, Scott Fausti

Natural Resource Management Faculty Publications

Early agriculture on western rangeland met with little success and resulted in serious consequences including soil erosion, loss of native woodlands and wildlife, and economic ruin. The Mortenson family in Stanley County, South Dakota, has been engaged in restoring degraded rangeland on their ranch for more than 50 years. Their primary goal has been to return the land to its condition prior to white settlement while maintaining a profitable cattle ranching operation. In recent years the ranch has served as a model of successful ranching based on a conservation ethic. This guidebook summarizes the restoration techniques and grazing regime used …

Bats Of The Antillean Island Of Grenada: A New Zoogeographic Perspective, Hugh H. Genoways, Carleton J. Phillips, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

The island of Grenada is the southernmost of the Lesser Antilles, lying 130 km north of Trinidad and 135 km north of the Venezuelan mainland. It measures 34 km north to south and 19 km east to west and has an area of 312 square km. Grenada and the Grenadines northward to Bequia stand on the large submarine Grenada Bank. At 183 m depth, the bank is 179 km long. The Grenadines cover the bank to its northern end, but the bank extends for 39 km south of Grenada with no islands.

The Effect Of Calf Morbidity On Feedlot Performance And Profitability, Jessica Gentry

Masters Theses & Specialist Projects

Two "Value-Added Calf (VAC) Programs were evaluated relative to feedlot performance and profitability. Two hundred seventy-three head of feeder calves were included in this study. Ninety-five Certified: Preconditioned for Health (CPH), ninety KCA Gold Tag and eighty-eight "Sale Barn" cattle were fed at Horton's Research Feedyard in Fort Lupton, Colorado. No background information regarding the health status of the Sale Barn cattle was known. Cattle were purchased in December 1997 and were entered in the Rocky Mountain Ranch-to-Rail program on January 6, 1998. The cattle were checked daily for illness and taken to a hospital pen for treatment if symptoms …

Radiocarbon From Nuclear Testing Applied To Age Validation Of Black Drum, Pogonias Cromis, Steven E. Campana, Cynthia M. Jones

OES Faculty Publications

Radiocarbon ((14)C) in the world's oceans increased sharply between 1950 and 1970 as a result of the atmospheric testing of nuclear weapons. Through comparison with the (14)C time series reconstructed from atmospheric measurements and marine carbonates, Kalish, in 1993, used the (14)C concentration measured in fish otolith cores as a means of confirming the annulus-based age estimates for some South Pacific fish species. Here we report the pre-and postbomb (14)C chronology of North Atlantic adult black drum (Pogonias cronis), assumed to be between 15 and 42 yr of age on the basis of otolith annulus counts. According to …

Winter Macroinvertebrate Communities In Two Montane Wyoming Streams, Christopher M. Pennuto, Frank Denoyelles Jr., Mark A. Conrad, Frank A. Vertucci, Sharon L. Dewey

Great Basin Naturalist

Macroinvertebrate communities were examined on 4 winter dates over a 4-yr period in 2 high-altitude Rocky Mountain streams to document overwintering assemblages potentially experiencing spring acid pulses. Taxa richness values were comparable to other published lists for alpine and montane stream systems despite the fact that most literature reflected summer collections. Mean benthic density ranged from 1406 to 19,734 organisms/m², and drift rates ranged from 0 to 1740 organisms/100 m³. Benthic collections showed higher taxa richness than drift collections while the Ephemeroptera and Plecoptera occurred in greater proportions in drift than in benthos. The Nemouridae (Plecoptera), …

Comparison Of Observed And Simulated Grow-Finish Swine Performance Under Summer Conditions, Larry W. Turner, Thomas C. Bridges, Richard D. Coffey, Richard S. Gates, Gary R. Parker, Tami M. Brown-Brandl, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

As a part of a National Pork Producers Council educational program, our research and extension team at the University of Kentucky was linked with an independent commercial swine producer to test the NCPIG model against observed commercial on-farm data. This experience provided improved information for model development as well as increased producer insight into the data input needs and potential benefits of modeling. Detailed production information comparisons between the NCPIG model and producer data are presented for summer time conditions to assess the validity of the NCPIG model for simulation of grow-finish swine performance. Results demonstrated that the NCPIG model …

Review Of A Guide To The Nests, Eggs, And Nestlings Of North American Birds, Paul A. Johnsgard

Papers in Ornithology

In 1978, during a visit to England, I purchased a copy of the first edition of this book, then called a field guide. It was written by Colin Harrison, published by Collins, and produced in standard field guide size. It never was effectively distributed in North America, which was unfortunate, because it was far better than the guide to bird nests by Hal Harrison in the well-known Peterson field guide series. Not only did it illustrate the eggs of about 550 species, in color and life size, but it also offered nestling paintings of nearly 150 species, plus numerous line …

Abundance And Seasonal Distribution Of The Marbled Murrelet In Puget Sound And Hood Canal In Fall And Winter, Richard Anthony Jensen Merizon

Dissertations and Theses

The greater Puget Sound area is home to a diversity of seabirds, however with encroaching human recreational and economic use of these areas these birds are facing unique threats. It is vitally important that we understand where these seabirds occur in order to minimize the risks associated with human influences. Intensive and extensive transects were used to collect data on seasonal distribution and abundance of seabirds, specifically marbled murrelets (Brachyramphus marmoratus), in Puget Sound and Hood Canal. Surveys were conducted from the water during the fall and winter in 1995 and 1996 and summer of 1997. Marbled murrelets were abundant …

Fmri Of Monkey Visual Cortex, Lisa Stefanacci, Paul Reber, Jennifer Costanza, Eric Wong, Richard Buxton, Stuart Zola, Larry R. Squire, Thomas D. Albright

Neurology Collection

While functional magnetic resonance imaging (fMRI) is now used widely for demonstrating neural activity-related signals associated with perceptual, motor, and cognitive processes in humans, to date this technique has not been developed for use with nonhuman primates. fMRI in monkeys offers a potentially valuable experimental approach for investigating brain function, which will complement and aid existing techniques such as electrophysiology and the behavioral analysis of the effects of brain lesions. There are, however, a number of significant technical challenges involved in using fMRI with monkeys. Here, we describe the procedures by which we have overcome these challenges to …

In the first section, an option for enhancing the catch value by transferring lobsters …

Fisheries Research Report No. 110 - A Research Vessel Survey Of Bottom Types In The Area Of The Abrolhos Islands And Mid-West Trawl Fishery., C. J. Dibden, L. M. Joll

Fisheries Research Reports

To address the concern expressed by Commercial rock lobster fishers operating in the Abrolhos Islands area, that expanding saucer scallop trawl activity was damaging the sea floor biota in areas which they considered good rock lobster habitat and poor scallop habitat, an underwater video survey was conducted by the Fisheries Department Research Division, with the following objectives:

1. Examine, classify and map the benthic habitat of areas currently and historically trawled for scallops in the Abrolhos Islands area and adjacent waters;

2. Examine, classify and map the benthic habitat of areas adjacent to these trawled areas, where potential for conflict …

In Memoriam: Charles G. Sibley, Paul A. Johnsgard

Nebraska Bird Review

On April 12 this year, Dr. Charles Sibley passed away in California. Although a Nebraskan by neither birth nor occupation, his work on hybrid zones among various passerines in the Platte Valley of central Nebraska during the 1950s became a model for modern studies in field approaches to both evolutionary biology and species-level taxonomy. His study also identified for the first time the Platte Valley as a major evolutionary "suture zone" between eastern and western avifaunas. When I arrived at Cornell in 1955, all of Dr. Sibley's graduate students were doing their fieldwork in Nebraska, collecting specimens of the various …

Wild Primate Populations In Emerging Infectious Disease Research: The Missing Link?, Nathan D. Wolfe, Ananias A. Escalante, William B. Karesh, Annelisa Kilbourn, Andrew Spielman, Altaf A. Lal

Harold W. Manter Laboratory of Parasitology: Library Materials

Wild primate populations, an unexplored source of information regarding emerging infectious disease, may hold valuable clues to the origins and evolution of some important pathogens. Primates can act as reservoirs for human pathogens. As members of biologically diverse habitats, they serve as sentinels for surveillance of emerging pathogens and provide models for basic research on natural transmission dynamics. Since emerging infectious diseases also pose serious threats to endangered and threatened primate species, studies of these diseases in primate populations can benefit conservation efforts and may provide the missing link between laboratory studies and the well-recognized needs of early disease detection, …

Genetic Parameters For Sex-Specific Traits In Beef Cattle, R. K. Splan, Larry V. Cundiff, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Data from 3,593 beef heifers and 4,079 of their steer paternal half-sibs were used to estimate genetic parameters of and among female growth and reproductive traits and male carcass traits. Estimates of heritability for adjusted 205-d weight, adjusted 365-d weight, age at puberty, calving rate, and calving difficulty measured on females were .16, .38, .47, .19, and .18, respectively; estimates for calving rate and calving difficulty were expressed on a normal scale. Estimates of heritability for hot carcass weight; retail product percentage; fat percentage; bone percentage; rib eye area; kidney, pelvic, and heart fat percentage; adjusted fat thickness; marbling score; …

Major Histocompatibility Complex Class I- And Ii-Deficient Knock-Out Mice Are Resistant To Primary But Susceptible To Secondary Eimeria Papillata Infections, Marco L. Schito, Bill Chobotar, John R. Barta

Faculty Publications

Two distinct mechanisms seem to function in reducing oocyst output during Eimeria papillata infections in mice. For naive mice, immunity was afforded by a T-cell-independent gamma-interferon (IFN-γ) response mediated by natural killer (NK) cells. On reinfection, resistance was associated with T-cells and, to a lesser extent, perforin. To determine if antigen presentation with major histocompatibility complex (MHC) molecules was required to control oocyst production by NK cells during primary infection or by T-cells during secondary infection, mutant mice that lacked H2-IAβb (Aβb(-/-)) or β2-microglobulin (β2m(-/-)) were used. Since MHC molecules are required for the maturation of αβ T-cells, Aβb(-/-) and …

The Effects Of Pool Size On The Microinvertebrate Populations Of Chaney Lake, An Ephemeral Wetland Located In Bowling Green, Kentucky, Shannon Gaines

Mahurin Honors College Capstone Experience/Thesis Projects

Studies concerning the microinvertebrate communities of differing pool sizes were conducted at Chaney Lake, an ephemeral, karst wetland located in Bowling Green, Kentucky. As the lake begins to dry in the early summer, smaller, isolated ponds begin to form. Several ponds of various sizes were marked for analysis. Microinvertebrate samples and physiochemical readings were taken at each of the sites and were counted in the lab. T-tests were performed on the samples to determine if the microinvertebrate densities differed between ponds that dried later in the season as opposed to those that dried earlier. Ostracoda densities of the late dry …
