Ovarian Follicular Development In Prepubertal Heifers Is Influenced By Level Of Dietary Energy Intake, E. G. M. Bergfeld, F. N. Kojima, Andrea S. Cupp, M. E. Wehrman, K. E. Peters, M. Garcia-Winder, J. E. Kinder

Department of Animal Science: Faculty Publications

Objectives were twofold: 1 ) to determine the chronology of development of dominant ovarian follicles during the peripubertal period in heifers and 2) to determine whether feeding a diet with low energy content that delays onset of puberty alters chronology of dominant ovarian follicular development in peripubertal heifers. Ten heifers of composite breeding ( 1/4 Angus, 1/4 Hereford, 1/4 Red Poll, 1/4 Pinzgauer) were randomly assigned, at 8 mo of age, to receive a diet designed to produce 0.9 (n = 5) or 0.3 (n = 5) kg body weight gain per day for the duration of the experiment.

Water-Nymphs Of The Platte, Patricia W. Freeman, Keith Perkins

University of Nebraska State Museum: Mammalogy Papers

Little known, but hauntingly beautiful and valuable to the environment as well, clams and mussels inhabit many Nebraska lakes and rivers. In the first survey of the entire Platte River, the authors found 11 species.

We surveyed mollusks (clams and snails) of the Platte River during the summers of 1990 and 1991. With the exception of the Big Bend reach of the river in Dawson, Buffalo, and Hall counties, no mussels were found in the river's main channel. But in backwaters, lakes and sand-pits along the river, we found 11 species of mussels at 49 different sites from east to …

Luteinizing Hormone Has A Role In Development Of Fully Functional Corpora Lutea (Cl) But Is Not Required To Maintain Cl Function In Heifers, K. E. Peters, E. G.M. Bergfeld, Andrea S. Cupp, F. N. Kojima, V. Mariscal, T. Sanchez, M. E. Wehrman, H. E. Grotjan, D. L. Hamernik, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

We tested the hypothesis that endogenous pulses of LH have a role in development and maintenance of CL during the estrous cycle of the bovine female. Twenty heifers were synchronized to estrus by treating two times with prostaglandin F_2α 11 days apart (Day 0 = behavioral estrus). Heifers were then randomly assigned to one of four treatments (n = 5/group). Heifers were treated with an antagonist to LHRH (LHRH-Ant; N-Ac-D-Nal[2]¹,4C1-D-Phe² ,D-Pa[3] ³,D-Cit ⁶,D-Ala¹⁰-LHRH; 10 μg/kg body weight) or vehicle (5% mannitol) once every 24 h: 1) LHRH-Ant Days 2-7, 2) LHRH-Ant Days …

The Identification And Reporting Of Physical Abuse By Physicians: A Review And Implications For Research, Jody E. Warner, David J. Hansen

Department of Psychology: Faculty Publications

Identification and reporting of possible cases of child physical abuse are critical precursors to intervention with maltreating families. Professionals from a variety of disciplines are mandated to report suspected cases of child maltreatment. Unfortunately, not all physically abused children are identified or reported. This paper reviews the literature that has examined factors that may influence the identification and reporting of physical abuse by physicians. The literature review is preceded by an overview of the multistep, multibehavior process of identification and reporting. The factors that may influence identification and reporting are discussed according to their association with the case, physician, or …

Extra-Legal Factors And Product Liability: The Influence Of Mock Jurors’ Demographic Characteristics And Intuitions About The Cause Of An Injury, Brian H. Bornstein, Michelle Rajki

Department of Psychology: Faculty Publications

Two experiments were performed to investigate the role of extra-legal factors in a simulated product liability trial. In cases where the factual evidence was identical, subjects’ liability judgments varied as a function of the case-specific factor of the alleged source of the plaintiff’s injury. In deciding cases differently depending on the alleged cause, subjects relied on intuitions about what injury sources are more or less likely to cause a certain kind of injury. Juror- specific factors also influenced subjects’ verdicts. There was no difference between students and non-students, but race and SES—factors that are often correlated with student status—did affect …

Wild Medicine: Review Of Medicinal Wild Plants Of The Prairie By Kelly Kindscher, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

I am highly enthusiastic about this book as a reference work. It summarizes the literature on the medicinal uses for more than 103 prairie plants. For 43 species, Kindscher gives common, Indian, and scientific names; description; habitat; parts used; Indian uses; medical history; scientific research and cultivation; and information on about 100 of their relatives. Another 60 entries are condensed to 24 paragraphs. Full-page line drawings by William S. Whitney of the major species are generally excellent, and all 103 entries have distribution maps. The introduction discusses the region covered, with helpful maps. There's an index, a glossary and a …

Identification And Characterization Of A Human Herpesvirus 6 Gene Segment Capable Of Transactivating The Human Immunodeficiency Virus Type 1 Long Terminal Repeat In An Spl Binding Site-Dependent Manner, Jinhai Wang, Clinton J. Jones, Michael Norcross, Ernst Bohnlein, Abdur Razzaque

School of Veterinary and Biomedical Sciences: Faculty Publications

The human immunodeficiency virus type 1 (HIV-1) long terminal repeat (LTR) is transactivated by various extracellular signals and viral cofactors that include human herpesviruses. These transactivators are capable of transactivating the HIV-1 LTR through the transactivation response element, NF-KB, or other regulatory binding elements. Human herpesvirus 6 (HHV-6) is a potential cofactor of HIV-1. Here, we report that an HHV-6 gene segment, ZVH14, which can neoplastically transform NIH 3T3 and human keratinocytes, is capable of transactivating HIV-1 LTR chloramphenicol acetyltransferase constructs in an Spl binding site-dependent manner. Transactivation increased synergistically in the presence of multiple Spl sites and was dramatically …

Policy Considerations For Contraception In Wildlife Management, Wendy A. Sanborn, Robert H. Schmidt, Herbert C. Freeman

Vertebrate Pest Conference Proceedings: 16th (1994)

Managing wildlife populations by manipulating their birth rates is a promising technology. However, the use of contraceptive technologies will involve the development of new wildlife management policies. We designed and implemented a survey that was intended to gather information on the range of perspectives of concerned publics on contraceptive use in wildlife management. There appears to be considerable confusion and mistrust regarding the application and appropriateness of this new technology. We recommend that promoters of contraception use in wildlife management be careful to explain what this new technology can and cannot do in order to avoid the pitfalls associated with …

The Prospects And Associated Challenges For The Biological Control Of Rodents, Grant R. Singleton

Vertebrate Pest Conference Proceedings: 16th (1994)

Biological control using macro- or micro-parasites is a promising research area for control of rodents. The largest impediment to progress is a dearth of high quality research, under field conditions, on wild rodents and their diseases. A major challenge is to identify a candidate control agent which is sufficiently pathogenic, has a high transmission rate and is target specific. Once this has been done, ecological studies of both the host and the disease agent, and of the epidemiology of transmission, are required. Whether the desired pathogenicity is via increased mortality and/or reduced fertility will depend on the agent and on …

Wild Carnivores As Plague Indicators In California - A Cooperative Interagency Disease Surveillance Program, Charles R. Smith

Vertebrate Pest Conference Proceedings: 16th (1994)

A cooperative interagency program of sampling and testing wild carnivores for plague antibody has been utilized as an important component of an integrated plague surveillance program in California since 1974. The carnivore serology program involves the California Department of Health Services, the U.S. Department of Agriculture, APHIS/Animal Damage Control, the U.S. Department of Health and Human Services, Centers for Disease Control, and various other cooperators. This paper summarizes the results of the testing of wild carnivores, opossums, and feral pigs over the past two decades from 49 of California's 58 counties, and discusses the importance of the program to the …

Ground Squirrel Management In The Angeles National Forest, Robyn K. Spano

Vertebrate Pest Conference Proceedings: 16th (1994)

In 1987 and 1988 there was a sharp rise in epizootics in the ground squirrel (Spermophilus beecheyi) population in the Arroyo Seco District of the Angeles National Forest. In response to these incidents, a proactive rather than a reactive approach was implemented in this area. This was the beginning of a ground squirrel management program in the Angeles National Forest. From 1988 to 1993 the program developed into a joint management program between the United States Department of Agriculture, Forest Service (USFS), Los Angeles County Department of Health Services (DHS), Los Angeles County Agricultural Commissioner's Office-Weights and Measures …

Effects Of Initial Rat Captures On Subsequent Capture Success Of Traps, Mark E. Tobin, Robert T. Sugihara, Richard M. Engeman

Vertebrate Pest Conference Proceedings: 16th (1994)

Trapping records from studies conducted in Hawaiian sugarcane fields were analyzed to determine the effects of rat captures on subsequent capture success of Rattus norvegicus, R. rattus, and R. exulans. Traps that captured rats were subsequently more likely to capture another rat of the same species. We detected no differences in trap responses of males and females, nor did we observe any evidence that capture success of Polynesian rats and roof rats was affected by previous captures of Norway rats. This increased trap success may have been due to residual trap odors, or to greater success of traps …

Activity Patterns Of The Pocket Gopher Pappogeomys Merriami Merriami In A Mexican Rangeland, Desley Whisson, Beatriz Villa-C.

Vertebrate Pest Conference Proceedings: 16th (1994)

Pocket gophers (Pappogeomys meiriami merriami) are a problem in both crops and rangelands of Mexico. In rangelands, damage results from the animals burrowing habits which cause much soil disturbance, and their feeding on rangeland vegetation. Although considered a pest, to date there have been no quantitative studies of the activity and damage caused this species. This study was initiated to document fluctuations in activity of P. m. merriami throughout the year in a Mexican rangeland.

Natural History And Protection Of Burrowing Owls, Clark S. Winchell

Vertebrate Pest Conference Proceedings: 16th (1994)

Burrowing owls (Speotyto cunicularia) were monitored over a four year period at Naval Air Station North Island, a developed area at the north end of San Diego Bay, California. Protection of the nest burrows and a burrow marking program were initiated in 1991. The breeding population increased from 14 to 27 nests after this marking program began. Burrow types and ways to differentiate burrows used by owls from those used by California ground squirrels (Spermophilus beecheyi) are outlined. The importance of burrows and their management is discussed with reference to the natural history of the owl.

Supplemental Bear Feeding Program In Western Washington, Georg J. Ziegltrum

Vertebrate Pest Conference Proceedings: 16th (1994)

Black bear (Ursus americanus) damage to trees is a severe problem in the Pacific Northwest. Significant damage has been observed for many years, especially in highly managed private industrial forests in western Washington. The introduction of intensive silvicultural techniques resulted in higher yields, but may have also made trees more vulnerable to black bear destruction. Early lethal control efforts lost public support and the forest products industry investigated different methods that concentrated on non-lethal management tools. In 1985, the Washington Forest Protection Association introduced supplemental bear feeding as a damage prevention program in high damage areas during the …

We hope we have provided adequate opportunities for informal networking, as this can be equally valuable as the scheduled papers and presentations.

Rodent Pests In Colombian Agriculture, Danblo Valencia, Donald J. Elias, Jorge A. Ospina

Vertebrate Pest Conference Proceedings: 16th (1994)

The tropical zones of Latin America are sources of a great faunal richness. A significant number of mammals are associated with damage to the agricultural and livestock industries of Colombia. Some studies have indicated that rodents cause serious economic and social damage in the agricultural, livestock, and stored product sectors of the Colombian economy. Evaluations of this damage have been based on three criteria: 1) the characteristics of the damage; 2) the species of rodent involved; and 3) the loss of production at harvest. Cereals and oil-producing crops are most affected as standing crops; in the livestock area, poultry and …

Using Geographic Information Systems For Tracking An Urban Rodent Control Program, Matt Von Wahlde, Bruce A. Colvin

Vertebrate Pest Conference Proceedings: 16th (1994)

Geographic information system technology is being used to help coordinate an urban rodent control program initiated as part of the Central Artery/Tunnel Project in Boston. Databases with neighborhood survey data, surface and subsurface baiting data, sanitation code violations, and public complaints are linked to base mapping, land parcel, and utility graphics. This integrated approach helps Project biologists plan control strategies and evaluate the relatedness of rodent activity to environmental conditions. Spatial querying techniques and the ability to graphically display and map variables, such as bait stations and sanitation deficiencies, help ensure that control resources are effectively targeted and tracked. This …

Zinc Phosphide: Implications Of Optimal Foraging Theory And Particle-Dose Analyses To Efficacy, Acceptance, Bait Shyness, And Non-Target Hazards, Ray T. Sterner

Vertebrate Pest Conference Proceedings: 16th (1994)

The U.S. Department of Agriculture (USDA), Animal Plant and Health Inspection Service (APHIS) maintains six federal registrations for zinc phosphide (Zn3P2); three of these address the control of eight rodent species using steam-rolled oats (SRO) or wheat grains in diverse applications. Optimal foraging theory (OFT) and "particle-dose analysis" (PDA) afford predictions relevant to the efficacy, acceptance, bait shyness, and non-target hazards of these Zn₃P₂ baits. For PDA, numbers of SRO groats or whole wheat grains associated with acute oral median lethal (LD^) or approximate lethal (ALD) doses of Zn3P2 were compared among nine target rodent and eleven …

Registration Requirements For Non-Toxic Natural Products As Animal Damage Control Agents, Stephen A. Schumake

Vertebrate Pest Conference Proceedings: 16th (1994)

Plant extracts, animal glandular secretions and excretions, and natural food flavoring agents are common sources of natural products that can be used in animal damage control applications. Such products can be used either by themselves (e.g., coyote urine as a rodent repellent), or in combination with other control agents (e.g., food odor or flavor enhancer at baiting sites). The Environmental Protection Agency registration requirements are described for a variety of potential applications of natural products including bird and rodent repellents. In some applications, the product chemistry or other data requirements could make the registration process prohibitive due to the cost …
