The Use Of Aversive Agents For Predator Control, M.P. Botkin

Great Plains Wildlife Damage Control Workshop Proceedings

The studies have continued in the search for potentially aversive compounds and mixtures. To date, undecenovanillylamide is the most effective substance found and is most effective in a mixture with p-dichlorobenzene. Three materials which have been tested actually appear to stimulate attack by coyotes on the treated animal. These are: Skatol (a fecal compound), Naphthalene and Thiomalic acid ( a foul sulpher-like odor).

The Extension Approach To Wildlife Damage, Dr. H.G. Geyer

Great Plains Wildlife Damage Control Workshop Proceedings

The Extension Service is the educational arm of the U.S. Department of Agriculture. It is recognized as the largest, most successful informal educational organization in the world. Funded and guided by a partnership of federal, state, and local governments, it delivers information to help people help themselves through the land-grant university system. Programs embrace broad categories of agriculture, natural resources and environment, home economics, 4-H and other youth, and ocmmunity resource development. Extension programs are non-political, objective, and based on factual information obtained from university, government, and other sources to hellp people make their own decisions. Extension is also unique …

Usda Research On Impacts Of Predation, Russell L. Gum, Richard S. Magleby

Great Plains Wildlife Damage Control Workshop Proceedings

This research by the U.S. Department of Agriculture, Economic Research Service, was done at the direct request of Congress, and with special funding in fiscal years 1974 and 1975.
Basic questions guiding the research were:
1. How sizable are predation losses? How many producers are effected?
2. What effect has predation had on the decline of the sheep industry?
3. What are benefits and cost of predator control programs?

Skunk Rabies Control And Surveillance In Central And Eastern Montana, Gary Nesse, Kenneth Seyler

Great Plains Wildlife Damage Control Workshop Proceedings

A skunk rabies control and surveillance program was initiated by the Department of Livestock, Vertebrate Pest Control Bureau, within designated areas of Fergus, Fallon and Richland counties between January 1, 1975 and July 30, 1975. The use of strychnine eggs employed by trained, licensed government pesticide applicators plus cooperation of local citizens proved to be a safe and selective method for conducting such a program. Of the 83 skunks diagnosed rabid by the Fluroescent Antibody Test as the Department of Livestock Diagnostic Laboratory in Bozeman, 72 percent were taken from control areas; however, of 284 skunks examined from control areas, …

The Effects Of Coyote Control Operations On Non-Target Species In New Mexico, Gary Lee Nunley

Great Plains Wildlife Damage Control Workshop Proceedings

In February of 1972 the use of compound 1080, sodium cyanide, and strychnine in Federal coyote control programs and on Federal lands was halted as directed by Executive Order 11643. Shortly thereafter, the Environmental Protection Agency cancelled the registration of these same toxicants as used in predator control. These actions were taken at the recommendation of the Advisory Committee on Predator Control in their report to the Council of Environmental Quality and to the Department of the Interior.

An Extension Trapper Program, Jerry Riedel

Great Plains Wildlife Damage Control Workshop Proceedings

South Dakota's Extension Trapping Program originated in July 1971 when the Department of Game, Fish and Parks initiated this type of animal damage control program for the eastern one-half of South Dakota. The funding for this program is derived by assessing a surtax on all farmers and ranchers at a rate of 1 cent per head on all cattle and 4 cent per head on all sheep. The monies gained here is then annually matched by the Game, Fish and Parks through hunting, fishing and trapping license by the Game, Fish and Parks. However, for the last two years a …

Great Plains Wildlife Damage Control Workshop Proceedings

Research to control predator depredations is one of three projects within the Section of Predator Damage. The project is directed from Denver, with several biologists and technicians at field stations located in Twin Falls, Idaho; Uvalde, Texas; and Rawlins, Wyoming, as well as in Denver. This is a brief summary of our efforts during the past 12 months and should be considered an informal progress report.

A Mammalogist's View Of Current Mammal Damage Control Trends, Sydney Anderson

Great Plains Wildlife Damage Control Workshop Proceedings

Different mammalogists have different views on this subject. The following are mine. Historically, there was considerable controversy in the American Society of Mammalogists around 1930 on the question of predator control. The primary reasons for these different views, then and also now, are different value judgements. Science without non-scientific value judgements is not sufficient to lead one to a single view or set of views. Science embodies certain value judgments such as honesty, the public value of human knowledge, objectivity, the desirability of formulating testable hypotheses, and the examination of all relevant and available evidence. Scientists are human beings and …

Coydogs In Nebraska, Brian R. Mahan

Great Plains Wildlife Damage Control Workshop Proceedings

Skulls of 44 suspected coyote (Canis latrans) x dog (C. familiaris) hybrids, "coydogs" were collected in Nebraska from September 1975 through April 1976. Each skull was compared statistically with skulls of known coyotes, dogs, coydogs, gray wolves (C. lupus), and red wolves (C. rufus) for identification. Thirty-two males were identified as: 5 coyotes, 2 dogs, 25 coydogs; 12 females were identified as: 4 coyotes, 2 dogs, 6 coydogs. Three concentrations of hybrids were located in southeastern Nebraska.

Prairie Dog Management: Educational Assistance To Local Governmental Units, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

There is a long history of involvement between Kansas State University (formerly Kansas State Agricultural College) and township governmental units regarding control of prairie dogs. In 1901 and 1903, the Kansas legislature passed laws authorizing townships to conduct prairie dog control programs and providing funds for the College to conduct experiments on methods of controlling prairie dogs and gophers. The acts also directed the College to procure and furnish to the townships the proper prepared materials for prairie dog control. The Experiment Station began supplying strychnine baits in January of 1902 and continued this practice until 1970.

Predation On Big Game And Its Management, Samuel L. Beasom

Great Plains Wildlife Damage Control Workshop Proceedings

This paper summarizes information from the literature and personal observation to present an overview of the effects of predators on big game populations. Specifically it examines control of prey populations, culling of inferior prey, and stimulation of prey productivity. Food habit investigations were omitted because of the impossibility of evaluating the impact of predation by this approach because of a lack of population data.

Major Issues Facing Agriculture As Our Nation Moves Toward A Domestic And International Food And Agricultural Policy, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

It is a pleasure for me to speak this evening before such a distinguished group of agribusiness and academic representatives, all of whom have a common interest. Twenty years ago, that interest would have been denominated as "agricultural policy". Today it would be called "food policy", which presumably is a broader term. Food policy is usually defined to encompass the interests of everyone in the production and marketing process from producer to consumer. It is by no means limited geographically, but encompasses people and firms who are involved -- directly or indirectly, domestically and internationally - in the food business. …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examination of over 3,000 fish, all sciaenids, has shown that plerocercoids of Poecilancistrium caryophyllum infect Cynoscion nebulosus, Bairdiella chrysura, Sciaenops ocellata, C. arenarius, Micropogonias undulatus, and Pogonias cromis in Mississippi Sound. In addition to P. caryophyllum, a pseudophyllidean-like trypanorhynch also infected C. nebulosus and M. undulatus. Pseudogrillotia pleistacantha selectively infected large P. cromis, Pterobothrium heteracanthum infected M. undulatus, and Pterobothrium lintoni infected Menticirrhus americanus. Prevalence and intensity of infections of P. caryophyllum in C. nebulosus from Mississippi, roughly 40% of the fish each possessing an average of about two worms, …

Myxosoma Funduli Kudo 1918 (Protozoa: Myxosporida) In Fundulus Kansae: Summer Epizootiology, Stephen A. Knight, John J. Janovy Jr., William L. Current

John J. Janovy, Jr. Publications

The occurrence and distribution of the myxosporidan Myxosoma funduli on the gills of the plains killifish (Fundulus kansae) were investigated; Fundulus kansae is reported as a new host. Host samples from various sites on the South Platte River, Nebraska, were collected during the summer months of 1975 and 1976. The protozoan parasite population was shown to be overdispersed within the host population, and this distribution was similar to that described by the negative binomial equation. Demographic characteristics of the infected fish subpopulation were virtually identical to those of the whole fish population. Infection intensity was independent of gill …

Foods Of Juvenile, Brood Hen, And Post-Breeding Pintails In North Dakota, Gary Krapu, George Swanson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Pintail (Anas acuta) is a common to abundant nesting species in North Dakota, becoming more numerous during years of favorable water conditions and less so during drought. Stewart and Kantrud (1974) estimated breeding-populations of 304,000, 111,000 and 379,000 pairs in the Prairie Pothole Region of North Dakota during 1967-69, respectively. We studied food habits of juvenile and adult Pintails during the brood-rearing and post-breeding periods in North Dakota to learn their food requirements during these phases of the life cycle. Food habits of flightless juveniles have been studied in Alberta (Sugden 1973) and limited information on downy …

Beef Cattle Feedlot Runoff And Control In Eastern Nebraska, L. P. Schram, Lynn R. Shuyler

United States Environmental Protection Agency: Publications

This study was initiated to determine operational characteristics of runoff control facility components for beef cattle feedlots.

A runoff control facility was designed and constructed for a 3,000 head capacity feedlot in eastern Nebraska. Components of the runoff control facility included debris basins inside the pen and outside the pen, a holding pond, and a disposal system.

Results indicated that design volumes for the debris basins and holding ponds were effective in controlling runoff from the lots caused by snowmelt and rainfall for climatic conditions within eastern Nebraska. Characteristics of runoff transported solids from this large lot compared favorably with …

The History Of The Beach Erosion Board, Us Army, Corps Of Engineers, 1930-1963, Mary-Louise Quinn

Nebraska Water Center: Faculty Publications

The Beach Erosion Board (BEB) was an agency originally set up to deal with civil functions assigned to the Corps of engineers. However, Dr. Quinn describes how the agency’s expertise lead to it being assigned to prepare reports on possible landing beaches of interest to the allies during World War II.

Because the wartime effort was very successful the Beach Erosion Board continued to perform intelligence functions after the war. The staff engaged to intelligence work grew in size and importance.

In the fall of 1962, the military intelligence division was absorbed by the newly-created US Army Area Analysis Intelligence …

Sex And Violence: Can Research Have It Both Ways?, Richard A. Dienstbier

Department of Psychology: Faculty Publications

During the last decade, the literature on media exposure has been dominated by a single theoretical system of personality functioning—the social learning model. The model emphasizes that the disinhibition of already-learned behavior, the learning of new behaviors, and the establishment of patterns of personality result from observing the behavior of other people (models) and from vicarious reinforcement upon viewing those models successfully engaging in rewarded sequences of behavior.

It is a tribute to the degree to which social learning oriented psychologists have successfully influenced intellectual and governmental thinking that the model is seldom questioned as providing the appropriate basis for …

Stability Of Perceived Tension As A Function Of The Menstrual Cycle, Paula Englander-Golden, Keith A. Willis, Richard A. Dienstbier

Department of Psychology: Faculty Publications

The stability of tension judgments among males and females who were either taking or not taking combination low-progestin oral contraceptive pills was investigated. Judgments of interpersonal pressure in videotaped vignettes provided tension measures. The vignettes were presented in two sessions separated by two weeks. Correlations between pressure judgments of .94 for males, .79 for pill females and .40 for non-pill females (all sig < .002) supported the prediction that non-pill females experience the largest fluctuations in tension across the menstrual cycle. A significant number of non-pill females who changed their scores and who changed from midcycle to premenstrual-menstrual phases or vice versa between the two experimental sessions shifted their tension scores in the predicted direction (p < .04). As predicted, non-pill females scoring in the lower half on premenstrual-menstrual symptomatology were more consistent in pressure judgments than those high on symptomatology, with correlations of .51 (sig < .004) and .24 (NS) respectively. Analysis of pressure judgments as a function of menstrual phase and high-low symptomatology indicated a main effect for symptomatology (sig < .01) with the high group perceiving more pressure. Lack of a main effect for menstrual phase was attributed to large individual variations in tension scores. Results were interpreted as indicating physiological causality underlying the variability in tension across the menstrual cycle. Substituting the Repression-Sensitization dimension for symptomatology yielded no significant results which could lead to a psychological interpretation of such variability.

An Epornitic Of Avian Cholera In Waterfowl And Common Crows In Phelps County, Nebraska, In The Spring, 1975, Joseph Zinkl, Norm Dey, Joseph Hyland, James Hurt, Kenneth Heddleston

Nebraska Game and Parks Commission: Staff Research Publications

In the spring of 1975, many species of waterfowl and common crows (Corvus brachyrhynchos) were found dead in Phelps County, Nebraska. About 25,000 waterfowl and at least 3,000 crows died in the epornitic. Few waterfowl were seen dying, but the crows experienced a chronic illness during which they became debilitated and were lethargic and dyspneic. Gross and microscopic lesions in the waterfowl were typical for acute avian cholera. The crows had dank, firm areas within the lungs, a loosely adhered yellow fibrous material in the pericardial sac and air sacs and, occasionally, liver abscesses. Microscopically, focal punulent pneumonia …
