An Assessment Of The Coyote Problem In The Great Plains States, Dale A. Wade

Great Plains Wildlife Damage Control Workshop Proceedings

It has now been 21 months since President Nixon's Executive Order #11643 was issued and there has been a complete annual reproductive cycle in the coyote population of the western states without any major influence by chemical controls. The use of mechanical controls, including non-lethal methods, and greater emphasis on removing only specific offending animals has been advocated during this time as a solution where coyotes prey on domestic animals. With this brief look back, what have been the results?

We do not have absolute data on coyote numbers and livestock depredations resulting from this change in coyote management programs. …

Captan Toxicity To Fathead Minnows (Pimephales Promelas), Bluegills (Lepomis Macrochirus), And Brook Trout (Salvelinus Fontinalis), Roger O. Hermanutz, Leonard H. Mueller, Kenneth D. Kempfert

United States Environmental Protection Agency: Publications

The toxic effects of capt an on survival, growth, and reproduction of fathead minnows (Pimephales promelas) and on survival of bluegiIIs (Lepomis macrochirus) and brook trout (Salvelinus fontinalis) were determined in a flow-through system. In a 45-week exposure of fathead minnows, survival and growth were adversely affected at 39.5 μLg/Iiter. Adverse effects on spawning were suspected but not statisticaIly demonstrated at 39.5 and 16.5 μLg/Iiter. The maximum acceptable toxicant concentration (MATC), based on survival and growth, lies between 39.5 and 16.5 μLg/liter. The lethal threshold concentration (LTC) derived from acute exposures was 64 μLg/liter, …

Preliminary Interpretations Of Coyote Population Mechanics With Some Management Implications, Frederick F. Knowlton

Great Plains Wildlife Damage Control Workshop Proceedings

The need for control of coyote (Canis latrans) depredations and a simultaneous demand for recognition of the aesthetic and ecologic values of the species create a conflict in resource utilization that should be resolved through more intensive management. A coyote population model is proposed from current estimates of density, reproduction, population structure, and mobility. Densities of 0.5 to 1.0 coyote per square mile are frequently suggested, with occasional estimates of 4.0 or more per square mile. Reproductive rates fluctuate as functions of the proportion of females that ovulate, the average number of ova shed, and in utero viabilities. …

Ethnoscience As A Methodology In Indian Education: A Sioux And Apache Example, Elizabeth S. Grobsmith

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The utility of ethnoscience as a methodology to improve American Indian education programs is discussed. Data from two native American communities is presented, focusing on the cultural conflict prevalent in their schools. The San Carlos Apache, a reservation-tribe of Western Apache in Arizona and an off-reservation community of Oglala Sioux from North-western Nebraska, are compared, emphasis being placed on the linguistic and cultural problems prohibiting effective education. Specific ethnosemantic studies are cited for their illumination of cognitive dissonance between native Americans and non-Indian teachers.

The Role Of The Professional Geographer In Geographic Learning, Salvatore J. Natoli

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Professional geographers have had a traditional interest and role in geographic learning. Specifically, the professional geographer referred to is the university or college professor who considers upper division teaching, graduate level teaching, and research as his primary responsibilities.

Experiences and attitudes occupy key positions in determining broader participation of professional geographers in geographic learning.

The professional geographer must view his role within a broader context .. that of the entire educational experience. In addition he must reexamine the goals of education and his roles within them rather than rest upon his scholarly credentials. He must help to provide the public …

A Brief History Of Extension Predator Control In Missouri, Dan F. Dickneite

Great Plains Wildlife Damage Control Workshop Proceedings

Missouri, like many of its neighbors, has long had to content with complaints of damage caused by predatory wildlife. Unlike some other states, however, in Missouri the control, management, restoration, etc. of all bird, fish and game and other wildlife resources of the state is vested in a Conservation Commission to an exclusive degree. Because of this Constitutional mandate, the Conservation Department in Missouri has been the agency primarily responsible for assisting farmers and ranchers with their various wild animal damage control problems. Poisons and explosive or chemical devices are not legal. This legal prohibition not withstanding, Missouri's relatively dense …

Summary, Dan F. Dickneite

Great Plains Wildlife Damage Control Workshop Proceedings

During this workshop we have heard from some of the leading animal damage control and livestock management specialists in the Great Plains and adjoining states. It appears that western states personnel will likely be involved in wild animal damage control to a greater extent than before as control activities are passed from federal to the separate state agencies--hopefully, with financial assistance for both implementation and research.

There is no widespread agreement on numbers or severity of damage, or on the best damage control techniques to use. What works in one area of the country will not necessarily work in another. …

Extension Wildlife Damage Control In Arkansas, Rocky Lynch

Great Plains Wildlife Damage Control Workshop Proceedings

With the curtailment of a service type predator control program that existed in Arkansas for 29 years, the Arkansas Game and Fish Commission in 1970 initiated a Nuisance Animal Control Section within the framework of the Commissions' Game Division. This extension - demonstration type wildlife control unit was named such because of the increase in rodent control (beaver and muskrat) within the state. Their numbers were spawned by the habitat inhancement in the delta and timber growing regions of Arkansas.

A Game Biologist visited the Missouri Department of Conservation and observed the technique of their predator control agent. With ideas …

Extension Wildlife Damage Control In Colorado, Dale A. Wade

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife damage control in Colorado may be more varied and difficult than in some other states. Colorado has a widely diversified agricultural, industrial and recreational business base and a great range of human density from the Denver Metropolitan area containing approximately half of the state population to the semi-desert and mountain areas where the population density is extremely low.

Approximately 40 percent of the land is federally owned, much of this in large tracts in the western two-thirds of the state. Privately owned land in this western area is primarily distributed along the more accessible valleys of major drainages. It …

Department of Animal Science: Faculty Publications

Data involving 505 Gene Pool boars, barrows and gilts and 126 Hampshire boars and gilts fed two nutritional diets were presented. One diet consisted of high lysine corn, minerals and vitamins (10% protein) while the other diet was a 14% protein corn-soy diet.

Eutrophication Of Small Reservoirs In Eastern Nebraska, Mark J. Hammer, Gary L. Hergemader

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Numerous small reservoirs constructed in Nebraska are used for recreation and many more are being planned. While these impoundments seemingly alleviate the long standing need for recreational waters, many existing impoundments exhibit symptoms of accelerated eutrophication after only a few years of existence. It is natural that such lakes, impounding nutrient-rich water, should be productive and generate nuisances that interfere with projected recreational uses. Unfortunately, neither this fact nor the lack of feasible methods for nutrient control were perceived prior to providing recreational facilities at the reservoir sites.

Rates of eutrophication, nutrient sources, and eutrophication control have been examined in …

Critical Flicker Frequency In A Harp Seal, Pagophilus Groenlandicus (Erxleben, 1777), Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) in a free-swimming harp seal (Pagophilus groenlandicus) was investigated using behavioral techniques. The resulting CFF versus intensity contour indicates a definite rod-cone break, confirming a duplex photoreceptor population whose presence had not been observed in previous morphological reports.

Collard Insect Control, E. A. Heinrichs, E. E. Burgess, Charles A. Mullins

Department of Entomology: Faculty Publications

Collards, Brassica oleracea var. viridis, because of their nutritional value, are important vegetables in the diets of many Tennesseans. According to a survey conducted by R. D. Freeland of the University of Tennessee Institute of Agriculture, Tennessee produced 1,544 acres of fresh and 4,405 acres of processor collards in 1971. Most were grown on the Cumberland Plateau and in West Tennessee. Many insects attack collard foliage. Flea beetle feeding causes "shot holes" in the leaf. Various caterpillars such as the cabbage looper, Trichoplusia ni (Hubner) , and the imported cabbageworm, Pieris rapae (L.), are capable of severe defoliation (Figure …

Ovulation, Fertility And Prenatal Mortality In Heifers Treated With Pmsg Or Porcine Fsh, D. B. Laster

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

Ovulation rate, fertilization rate and prenatal mortality were studied in yearling beef heifers treated with PMSG or FSH and in non-treated controls. Oestrus was synchronized in 50% of the animals in each treatment with an oral progestagen. The gonadotrophin injections were given during the normal oestrous cycle or during the progestagen-administration period. All heifers were inseminated 6 to 10 hr after observation of standing oestrus.

Ovulation rate and percentage fertility were determined in approximately a third of the animals in each treatment group. The reproductive tracts of the remaining animals were examined 81 to 104 days after insemination for number …

Lice Of Public Health Importance And Their Control, Harry D. Pratt, Kent S. Littig

Harold W. Manter Laboratory of Parasitology: Library Materials

Lice have been intimately associated with man for centuries. Infestations with lice occur today in the United States and many other countries despite great efforts to maintain high standards of public health. Public health agencies are often called upon if infestations include or expose large groups of people, particularly those in public institutions such as schools, jails, hospitals, or homes for the aged.

The three sucking lice that infest humans are: the body louse (Pedlculus humanus humanus), the head louse (Pediculus humanus capitis), and the crab louse (Pthirus pubis). The body louse is the …

Control Of Leaf-Feeding Insects On Yellow-Poplar, E. A. Heinrichs, E. E. Burgess, Ellis L. Matheny Jr.

Department of Entomology: Faculty Publications

Yellow-poplar, Liriodendron tulipifera L., also known as the tulip-poplar, is an important source of pulpwood and saw timber, and it is widely used as a shade tree. Numerous insect species attack the foliage of yellow-poplar. In 1965, Odontopus calceatus (Say) was first observed seriously damaging yellow-poplar in Tennessee (Russell and Stanley 1967). Defoliation was so severe at the University of Tennessee Oak Ridge Forest Experiment Station that growth reduction was attributed to this pest (Buckner 1972). In 1967, observations by one of us (E.A.H.) indicated that several other insects attack yellow-poplar leaves during the spring. Infestations of the aphid Macrosiphum …

Two Species Of Bats New To The Fauna Of Trinidad, Hugh H. Genoways, Robert J. Baker, R. S. Loregnard

University of Nebraska State Museum: Mammalogy Papers

Goodwin and Greenhall (1961) in their monograph of the bats of Trinidad and Tobago recorded 58 species of chiropterans from the island of Trinidad. In two subsequent publications (Goodwin and Greenhall, 1962, 1964) these authors recorded Mesophylla macconnelli, Prornops nasutus, and Phylloderma stenops from Trinidad bringing the number of species known from the island to 61. In August 1967, one of us (R. J. Baker) and Larry Deaven netted bats on Trinidad in connection with ongoing studies of chiropteran karyology, and obtained two species not previously recorded.

An Incident Of Fenthion Mosquito Control And Subsequent Avian Mortality, Robert Seabloom, Gary Pearson, Lewis Oring, James Reilly

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

Mass mortality among migratory birds at Grand Forks, North Dakota, was attributed to a mosquito control operation employing the insecticide fenthion. The factors involved may have included the toxicity of the pesticide for birds, the method of application and coincidence with the peak of the spring warbler migration.

Device For Obtaining From Small Ponds Water Samples Or Lagoons, J. Kent Mitchell, Elbert C. Dickey

Department of Agricultural and Biological Systems Engineering: Faculty Publications

A research project was recently initiated which requires that water quality samples be taken from small ponds and lagoons in west-central Illinois. A method for obtaining these pond water samples was desired that could be handled conveniently by one person and would not require a small boat. The pond water sampler described here was developed to satisfy this need.

The sampler developed allows one person to obtain a water sample at any desired depth while remaining on the shore. After assembling the device it may be floated to any position on the pond surface, lowered to the desired depth, and …
