On The Notion That Insectivory Is A Specialized Condition, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Insectivory as a specialized feeding condition in mammals has not been explored as has been carnivory or herbivory. Insect-feeding, non-edentate mammals have dilambdodont teeth and modifications in the craniomandibular joint which distinguish them from other mammals such as carnivores, herbivores, and omnivores. Variation in a family of insectivorous bats, Molossidae, can be likened functionally to the kinetic-inertial and static-pressure jaw systems noted in rhipidistians, amphibians, and reptiles. Food data show that the bats with the kinetic-inertial system eat moths and ones with the static-pressure system eat beetles. Not only do these insectivorous mammals eat insects, they also are modified to …

Address Given At The Annual Convention Of The Ground Water Management Districts Association, Clayton K. Yeutter

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

It is good to be back in Nebraska. As many of you know, water resources was my major field of endeavor a dozen years ago when I was on the faculty of University of Nebraska. My Ph.D. dissertation involved water law and water administration in the central United States, and I know you have a number of states represented here that were involved in that particular study. Those states were Kansas, Colorado, Iowa and Nebraska, but with some spillover into other geographic areas as well. At that time, of course, I spent a lot of time with people like Don …

Observation Of Davydov Splitting In Pts Polydiacetylene Crystal Spectra, Hans Muller, Craig J. Eckhardt

Craig J. Eckhardt Publications

The electronic spectra of polydiacetylene crystals have often been typified by poly-2, 4-hexadiyne-1, 6-diol-bis-(p-toluene sulfonate) (PTS). The spectra of crystals of this polydiacetylene have been unique in that they have displayed a pronounced “doubling” of the 300 K spectral bands at temperature below 170 K. The reflection bands are also observed to undergo a continuous red shift with continued decrease of temperature. The reflection band observed at lowest energy at 300 K is resolved at 77 K into two clearly separated bands at 15,700 cm^-1 (Ib) and 16,050 cm^-1(IIb). A recent study by modulated piezoreflection …

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 …

Brief Summary Of Prebaiting Study For Prairie Dog Control, Ken Seyler

Great Plains Wildlife Damage Control Workshop Proceedings

Attached are two tables summarizing data collected during a pre-baiting study for prairie dog control. The study was conducted in the Pryor, Montana area of Big Horn County, July 13-21, 1977, and in the Tongue River area of Custer County, Montana, August 24-September 3, 1977, and October 17-24, 1977. Applications of strychnine oats (Sebesta's .44%) and zinc phosphide oats (U.S. Fish and Wildlife Service, Pocatello Suppy Depot, 2%) with and without prebait (steamrolled oats) were compared for effectiveness in the control of prairie dogs.

Trapper Education And Furbearer Management, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

Modern concepts of furbearer harvest on a controlled, sustained-yield basis are in accordance with recognized principles of wildlife management and natural resource conservation. Steel traps, in the hands of private citizens and regulated by state fish and game agencies, have been the primary tools used in this country for managing furbearers. Fur resource managers recognize that traps are important tools not only in furbearer management, but also in some programs of wildlife damage or disease control. Traps also provide a major source of outdoor recreation for many people.

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

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?

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.

Depredations Control Research Of The U.S. Fish And Wildlife Service, Denver Wildlife Research Center, James R. Tigner

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 …

Predation On Furbearers And Management Alternatives, Ronald D. Andrews

Great Plains Wildlife Damage Control Workshop Proceedings

Most of the presentations from other members of the panel have discussed direct predation of one animal upon another with evidence and data to support it. Their presentations indicate that in some instances, considerable data has been collected that substantiates the fact that predation has been and can be a limiting factor in sustaining certain local animal populations. Suggestions have also been made concerning management alternatives that might help to reduce this predatory impact when desirable. Predation on furbearers and its impact is considerably more ambiguous and abstract. Facts and data concerning significant predation on furbearers, except for mink on …

Long-Term Education Program In Predator Damage And Damage Control, Major L. Boddicker

Great Plains Wildlife Damage Control Workshop Proceedings

The models for long-term education programs in predator damage and damage control are the Missouri and Kansas systems. We owe a great deal of gratitude to the founders and successors of these programs. most of the other efforts going today in the Extension animal damage control programs are modifications of those efforts.

Organizing And Motivating Public Groups To Support Rational And Positive Wildlife Management Efforts, Major L. Boddicker

Great Plains Wildlife Damage Control Workshop Proceedings

One of the privileges of working in wildlife management is working with positive people who still support the American dream of hope and opportunity. They call a spade a spade and fight adversity with enthusiasm. They genuinely express themselves.

Youth Fur Harvest Programs, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

Youth fur harvest programs in Kansas have been developed as one phase of an overall series of youth education projects on ecology and the environment. Currently, the series includes Ecology, Acres for Wildlife, Kansas Mammals, Birds Around You, Reptiles and Amphibians, Fur Harvest, and Fishing. Basically, the fur harvester project was developed because, although many young people in the state are interested in trapping, few good sources of information or instruction were available to most young trappers. Because many objectionable trapping abuses are unintentionally caused by young or inexperienced trappers, it was hoped that this project would encourage ethical and …

Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe

Great Plains Wildlife Damage Control Workshop Proceedings

Distribution of the bobcat includes the 48 contiguous United States and limited occupance of southern Canada and northern Mexico. There are 11 subspecies, the one in Wyoming being Lynx rufus pallescens. Bobcats inhabit an amazing variety of habitat types, from northern boreal forests, southern swamp, and cane regions to the below sea level desert of Death Valley, California. Throughout this vast area, they utilize a wide variety of prey species. One study in Wyoming revealed at least 18 different species in the stomachs of bobcats; the cottontail rabbit being predominant. A similar study in New England revealed 20 different …

A Matter Of Understanding: An Environmental Protection Agency Film On Coyotes, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

This movie gives facts concerning the coyote. A better understanding of other living things will determine how responsibly we make adjustments in the environment and govern the earth we share with the coyote and other creatures.

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.

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, …

Coyote And Dog Depredations, Joe Schaefer, Ronald D. Andrews

Great Plains Wildlife Damage Control Workshop Proceedings

The objective of this study is to determine the impact of coyote and dog depredation on the sheep industry in southern Iowa and to evaluate the livestock husbandry practices associated with these losses. In order to obtain background information on sheep management practices and the number of alleged livestock losses caused by coyotes and dogs in southern Iowa, a questionnaire was sent to 3,173 sheep producers. Sixty-nine percent of the 1,260 respondents indicated that they did not have any problem with coyote depredations during 1975. However, the major cause of mortality was reported to have been coyote predation which accounted …

Great Plains Wildlife Damage Control Workshop Proceedings

Investigation by Fish and WIldife Srevice research biologist, Conrad Hillman and Department of Game, Fish and Parks have resulted in a five-month preliminary study of the swift fox in Shannon County, South Dakota. Thirteen fox were captured, marked, measured and released. Future plans will include an ecological study of the swift fox, introductions on private land for prairie dog control and a captive breeding program.

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.

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.

1977 Fall Field Day

Nebraska Bird Review

1977 Fall Field Day

The 1977 Fall Field Day started Saturday night with a get-together at the home of the George W. Browns in Kearney. Sunday, 2 October, started out gray and chilly, but eventually developed into the fine fall day which had been ordered and promised. The trip started at the Newark Township building and went north on Nebraska 10 to the north bank of the Platte River and explored eastward along the river. After that area had been covered the group went to an area northeast of Fort Kearney. After the lunch at the Newark Township building, at …

Sixty-Five Years Of Whooping Crane Records In Nebraska, Paul A. Johnsgard, Richard Redfield

Nebraska Bird Review

In 1933, Myron Swenk determined the status of the Whooping Crane in Nebraska by summarizing all of the records then available to him, and established the general pattern of timing and geographic distribution of Whooping Crane occurrence in this state. Although the population of this species has remained very low since that time, a sufficient number of observations have been made to warrant updating his analysis and comparing the more recent records with these earlier ones. During the summer of 1977 the junior author undertook such a summary as a class project, by extracting such records from all of the …
