Dramatic And Immediate Improvements In Insular Nesting Success For Threatened Sea Turtles And Shorebirds Following Predator Management, Richard M. Engeman, Anthony Duffiney, Sally Braem, Christina Olsen, Bernice Constantin, Parks Small, John Dunlap, J.C. Griffin

United States Department of Agriculture Wildlife Services: Staff Publications

Predation critically threatens reproductive success of sea turtles and shorebirds at many of Florida's beaches. We examined the biological and bioeconomic results of predator management on two adjacent barrier islands, Cayo Costa and North Captiva, along Florida's west coast. Both islands suffered severe nesting losses due to predation and disturbance due to raccoons, while Cayo Costa also was impacted by a large population of feral swine. In 2006, our initial year of study, neither island received predator management and no least tern production occurred on either island, and sea turtle nest predation was 74% and 60%, respectively, for Cayo Costa …

Acute Toxicity Of Diphacinone In Northern Bobwhite: Effects On Survival And Blood Clotting, Barnett A. Rattner, Katherine E. Horak, Sarah E. Warner, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

The anticoagulant rodenticide diphacinone was slightly toxic (acuteoralLD₅₀ 2014 mg/kg) to Northern bobwhite (Colinus virginianus) in a 14-day acute toxicity trial. Precise and sensitive assays of blood clotting (prothrombin time, Russell’s Viper venom time, and thrombin clotting time) were adapted for use in quail, and this combination of assays is recommended to measure the effects of anticoagulant rodenticides. A single oral sub lethal dose of diphacinone (434mg/kg body weight) prolonged clotting time at 48 h post-dose compared to controls. At 783 mg/kg (approximate LD₀₂), clotting time was prolonged at both 24 and 48 h post-dose. …

Comparison Of Endocrine Response To Stress Between Captive-Raised And Wild-Caught Bighorn Sheep, Sarah Coburn, Mo Salman, Jack Rhyan, Thomas Keefe, Matthew Mccollum, Keith Aune, Terry Spraker, Lowell Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Stress hormones in Rocky Mountain bighorn sheep (Ovis canadensis canadensis), produced in response to environmental changes, road development, or high population density, may impact their immune systems to a threshold level that predisposes them to periodic, large-scale mortality. We compared the stress response to a novel environmental situation and repeated handling between bighorn sheep born and raised in captivity (CR) and bighorn sheep born in the wild (WC) and brought into captivity. We measured plasma epinephrine, norepinephrine, cortisol, and fecal glucocorticoid metabolites (FGM). Three weeks after each group’s arrival we used a one-time drop-net event to elicit an …

The Effect Of Enclosure Type On The Behavior And Heart Rate Of Captive Coyotes, Stacey P. Brummer, Eric M. Gese, John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

The potential for captivity to elicit changes in animal behavior and physiology is well known. Recent research on captive populations has examined the effect of feeding protocols, enclosure types, and enrichment programs on indices of stress and displays of species-typical behaviors. We investigated the impact of enclosure type upon captive coyotes (Canis latrans) by examining differences in coyote behavior and heart rate, among 3.3m² kennels (K), 65.5m² small pens (S), and 1000m² large pens (L). Time budgets and repertoire of species-specific behaviors were compared among each enclosure type and to a sample of wild (W) …

Review Of Issues Concerning The Use Of Reproductive Inhibitors, With Particular Emphasis On Resolving Human-Wildlife Conflicts In North America, Kathleen A. Fagerstone, Lowell A. Miller, Gary Killian, Christi A. Yoder

United States Department of Agriculture Wildlife Services: Staff Publications

This manuscript provides an overview of past wildlife contraception efforts and discusses the current state of research. Two fertility control agents, an avian reproductive inhibitor containing the active ingredient nicarbazin and an immunocontraceptive vaccine, have received regulatory approval with the Environmental Protection Agency and are commercially available in the USA. OvoControl G Contraceptive Bait for Canada Geese and Ovo Control for pigeons are delivered as oral baits. An injectable immunocontraceptive vaccine (GonaCon Immunocontraceptive Vaccine) was registered with the Environmental Protection Agency for use in female white-tailed deer in September 2009. An injectable product (GonaCon Immunocontraceptive Vaccine) is registered for use …

Fine-Scale Genetic And Social Structuring In A Central Appalachian White-Tailed Deer Herd, Brad F. Miller, Randy W. Deyoung, Tyler A. Campbell, Benjamin R. Laseter, W. Mark Ford, Karl V. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Spatial genetic structure in white-tailed deer (Odocoileus virginianus) has been examined at regional scales, but genetic markers with the resolution to detect fine-scale patterns have appeared only recently. We used a panel of microsatellite DNA markers, radiotelemetry data, and visual observations of marked deer to study fine-scale social and genetic structure in a high-density population of white-tailed deer (12–20 deer/km²). We collected genetic data on 229 adult females, 102 of which were assigned to 28 social groups. Our results were consistent with the conceptual model of white-tailed deer social structure, where philopatric females form social groups …

Potential Attractants For Detecting And Removing Invading Gambian Giant Pouched Rats (Cricetomys Gambianus), Gary W. Witmer, Nathan P. Snow, Patrick Burke

United States Department of Agriculture Wildlife Services: Staff Publications

BACKGROUND: Native to Africa, Gambian giant pouched rats (Gambian rats; Cricetomys gambianus Waterh.) are a threatening invasive species on a Florida island, Grassy Key. Gambian giant pouched rats shifted from a domestic pet to invading species after suspected release from a pet breeder. Because of the large size of Gambian rats (weighing up to 2.8 kg), they pose a serious threat to native species (particularly nesting species) and agricultural crops, especially if Gambian rats invade mainland Florida. Also, Gambian rats pose a threat from disease, as they were implicated in a monkeypox outbreak in the mid-western United States in 2003. …

Effect Of Channel Catfish Stocking Rate On Yield And Water Quality In An Intensive, Mixed Suspended-Growth Production System, Bartholomew W. Green

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This study was conducted to determine the effect of stocking rate on yield of channel catfish Ictalurus punctatus and water quality in a mixed suspended-growth (biofloc) production system with zero water exchange. Channel catfish (National Warmwater Aquaculture Center 103 strain; average fish weight -- 13 g) were stocked into nine 35-m² tanks (28 m³/tank) at a rate of 2.9, 5.7, or 8.5 fish/m² for a 238-d grow-out period. One 1.865-kW blower for every three tanks supplied air continuously through a diffuser grid (constructed of 2.5-cm-diameter polyvinyl chloride pipe) on the bottom of each tank. Well water …

T Cell Receptor Cross-Reactivity Directed By Antigen-Dependent Tuning Of Peptide-Mhc Molecular Flexibility, Oleg Y. Borbulevych, Kurt H. Piepenbrink, Brian E. Gloor, Daniel R. Scott, Ruth F. Sommese, David K. Cole, Andrew K. Sewell, Brian M. Baker

Food for Health: Publications

Tell mediated immunity requires T cell receptor (TCR) cross-reactivity, the mechanisms behind which remain incompletely elucidated. The αβ TCR A6 recognizes both the Tax (LLFGYPVYV) and Tel1p (MLWGYLQYV) peptides presented by the human class I MHC molecule HLA-A2. Here we found that although the two ligands are ideal structural mimics, they form substantially different interfaces with A6, with conformational differences in the peptide, the TCR, and unexpectedly, the MHC molecule. The differences between the Tax and Tel1p ternary complexes could not be predicted from the free peptide-MHC structures and are inconsistent with a traditional induced-fit mechanism. Instead, the differences were …

Assuming Elder Care Responsibility: Am I A Caregiver?, Lindsey E. Wylie, Eve M. Brank

Department of Psychology: Faculty Publications

Caregivers of the elderly face conflicting legal demands; they must make certain the elder’s needs are being met while not forcing undesired care on an adult capable of informed decisions. This dichotomy may be a reason a large volume of reported elder abuse derives from unintentional neglect on behalf of informal familial caregivers. The current research examines this possibility with exploratory interviews and an experiment. The interviews between elders and their family (30 dyads) revealed that many did not intend for the living arrangements to become permanent, and the nonelders were largely unprepared for the magnitude of changes and responsibilities …

Analysis Of Higher Education Employee Exercise Behaviors, Michele Linder

College of Education and Human Sciences: Dissertations, Theses, and Student Research

With the introduction of technology into our daily lives, the need for physical exertion has decreased, which has led to an increase in sedentary lifestyles. Sedentary lifestyles lead to the state of obesity, and nearly two-thirds of the Unites States’ adult population is considered overweight or obese. This has resulted in a reduced quality of life, adverse health effects that strain the health care system, and tension on the financial condition of American companies. Current literature indicates that organizations that had implemented exercise or wellness programs reported healthier and more productive employees, an improved morale within the company, and significant …

Parental Perceptions Of Body Mass Index Referrals And Overweight School-Age Children, Misty Schwartz

Department of Educational Administration: Dissertations, Theses, and Student Research

It is well documented that there is a worldwide epidemic of obesity in children. To address obesity in children, emphasis must be on factors within family, school, and community environments. Although most parents and school officials are aware of the problem of overweight children, there is little data available to guide decision making about the acceptability of school-based Body Mass Index (BMI) screening and referral programs. As states mandate BMI screening and referral, parental insight is essential to determine the efficiency and effectiveness of BMI notification.

The purpose of this multiple case study was to explore the perceptions of parents …

In Case You Missed It: China’S Monetary Challenges, Maura Dykstra

China Beat Blog: Archive 2008-2012

When I first left to study in China, I asked around about what presents to bring. I took the advice of a professor, and boarded a plane to Shanghai with two bottles of Johnny Walker and two cartons of Marlboro cigarettes. I had heard tales of men and women in China beseeching their foreign friends to purchase such items at Friendship Stores, and had been reassured that these name-brand products would be eagerly consumed by deprived whiskey-drinkers and smokers on the mainland. I wasn’t in China for more than a week when, stepping into a local convenience store, I was …

The College Experience: Exploring The Relationships Among Student Socioeconomic Background, Experiences Of Classism, And Adjustment To College, Autumn Loreene Backhaus

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of this study was to investigate the relationships between 1) student Socioeconomic (SES) background and adjustment to college, 2) SES background and experiences of classism and 3) experiences of classism and adjustment to college. It was predicted that 1) students from low-SES backgrounds would be less well adjusted than their peers from higher-SES backgrounds, 2) students from low-SES backgrounds would report higher levels of experiences of classism than higher-SES peers and 3) experiences of classism at college would be negatively related to overall adjustment to college. Study participants were first year college students from a large Midwestern University. …

Killing Of Treponema Denticola By Mouse Peritoneal Macrophages, P. Gaibani, C. Vocale, S. Ambretti, F. Cavrini, Jacques Izard, L. Miragliotta, M. T. Pellegrino, V. Sambri

Department of Food Science and Technology: Faculty Publications

Treponema denticola has been identified as an important cause of periodontal disease and hypothesized to be involved in extra-oral infections. The objective of this study was to investigate the role of T. denticola cell length and motility during mouse peritoneal macrophages in vitro uptake. Macrophages, incubated under aerobic and anaerobic conditions, produced a similar amount of TNF-α when stimulated with Escherichia coli LPS. The uptake of FlgE- and CfpA-deficient mutants of T. denticola was significantly increased compared with the wild-type strain, due to cell size or lack of motility. Opsonization with specific antibodies considerably improved the treponemes’ uptake. …

Defining And Measuring Poverty In Nebraska, Randolph L. Cantrell

Cornhusker Economics

Data recently released by the Census Bureau estimate that 47.4 million Americans, or about one-insix, are living in poverty. This latest estimate has drawn criticism from some observers who see it as an attempt to artificially inflate the magnitude of poverty in America. The criticism results from a change in methodology that included not just income (the Whitehouse Office of Management and Budget (OMB) poverty threshold for 2009 is $22,050 a year for a family of four), but also made adjustments, taking into account such things as region, out-of-pocket medical expenses and child care costs, that in total add about …

Five New Species Of Peltonotus Burmeister (Scarabaeidae: Dynastinae: Cyclocephalini) From Southeast Asia, Mary Liz Jameson, Kaoru Wada

Insecta Mundi

The Southeast Asian scarab beetle genus Peltonotus Burmeister (Scarabaeidae: Dynastinae) is associated with aroid flowers and possesses a unique, articulated maxillary tooth. We describe five new species of Peltonotus: P. animus and P. cybele from Sumatra, P. favonius from Vietnam, P. mushiyaus from Borneo, and P. tigerus from Thailand. The circumscription of P. karubei Muramoto is broadened to include new color variation, and the body size range for the genus is increased with Peltonotus mushiyaus, n. sp., now being the smallest member of the genus. We provide an amended key to species, distribution maps, diagnoses and accompanying comparative …
