Analysis Of Hunter Characteristics And Attitudes Relating To Utah Shooting Preserves, John T. Ratti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper evaluates the present status of Utah shooting preserves with special reference to attitudes and characteristics of hunters using and not using the shooting preserves system. Data were gathered primarily by a mail questionnaire survey.

Compared to non-users, shooting preserve users were more frequently raised in a suburban or city area, better educated, and had higher yearly incomes. Shooting preserve users were commonly employed as professionals or proprietors, while non-users were often employed as craftsmen, proprietors, or operators.

Most shooting preserve hunters hunted after the state game bird season was closed, and were generally satisfied with Utah preserves. Most …

The Effects Of Elevation And Vegetation Type On Snow Accumulation And Melt In Logan Canyon, Utah, Paul R. Thies

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Snow accumulation and melt characteristics were studied in Logan Canyon, Utah. Three replications of aspen, conifer, and open field types at 6300, 7100,and 8000 feet were measured for snow depth and water content during 1972. Elevation was found to have the greatest effect on snow water content. The gradient of increasing water content with rise in elevation was found to be .51 inches/100 feet in the zone from 6300 to 7100 feet and 1.9 inches/100 feet from 7100 to 8000 feet. The cooler temperatures at higher elevations partially account for the 8000 foot zone beginning to melt 40 days after …

This review also provides an opportunity to compare and contrast natural and social laws. From this examination of the problem of pollution and the interface between natural and social law emerge certain ideological concerns confronting Americans as a people.

Development Of An Interpretive Document For The Bear River Migratory Bird Refuge, William R. Burbridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since its inception, the National Wildlife Refuge System has been administered for management and restoration of habitat essential to the propagation and welfare of resident and wintering wildlife species. Acquisition of additional System units has been primarily directed to the benefit of the migratory bird resource. As of July 1, 1968 about 250 of the 321 refuge units were managed for the waterfowl resource (U. S. Department of Interior, 1968a). However, this growth of the System has been accompanied by an increase in recreational use of the refuges. In 1962, Public Law 87-714, the Refuge Recreation Act, was passed to …

Aquatic Invertebrate Consumption By The Major Fish Species In The Blacksmith Fork River, Theodore F. Meyers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Exponential rates of digestion are described for brown trout and whitefish for July, October, December (1969), and April (1970). The slope of the line fitted to the digestion data from each month was defined as the instantaneous rate of digestion and applied to an exponential growth model to determine the instantaneous consumption rate.

The digestion and consumption rates were applied to field measurements of percent fullness to determine the amount of food material ingested during a 24 hour period. Brown trout consumed 127, 24, 19, and 84 mean percent of their stomach capacity in the July, October, December, and April …

The Effects Of Available Water Upon Populations Of Chukar Partridge On Desert Mountains Of Utah, William W. Shaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of surface water to chukar partridges (Alectoris graeca) and the feasibility of rain-catchment devices for improving chukar habitat were studied on the Thomas and Dugway Mountain Ranges in western Utah during 1969 and 1970.

Sources of surface water were removed from one mountain range, and chukar populations on that range were compared with populations on an adjacent range with permanent sources of water.

Providing drinking water did not improve chukar productivity, survival, or availability to hunters. Although most birds concentrated around water supplies in the summer, some chukars appeared to live completely independent of any permanent …

The Coalville Deer Herd In Northeastern Utah: Its Ecology And Management, Gary L. Hickman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study on the Coalville Deer Management Unit adjacent to the corner of Wyoming in Utah was to determine the condition of the deer herd in relation to its range and population characteristics.

Postseason doe-fawn ratio was 100:77, while an adjusted doe-fawn ratio accounting for the unproductive female yearling segment was 100:105. The approximate net-productivity for 1964 was 44 percent compared to 27 percent in 1965. In 1964-65, the average age-class mortality rate for the male and female segments was 45 and 35 percent respectively. Preseason and postseason sex ratios were 64:100 and 60:100 respectively.

Ecology Of The Morgan Creek And East Fork Of The Salmon River Bighorn Sheep Herds And Management Of Bighorn Sheep In Idaho, James K. Morgan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An ecological study on the Morgan Creek and the East Fork of the Salmon River, Idaho, Bighorn Sheep herds was conducted from July 1, 1966 to February 28, 1970.

The Morgan Creek population numbered about 100 animals upon termination of the study. The trend of this population was downward. The East Fork population numbered about 50 animals and the trend appeared to be stable or slightly downward.

Productivity of both herds was low. Lamb mortality was high and recruitment to the breeding herd low. Low recruitment rates coupled with hunting pressure caused a decline in the ram component of both …

Pheasant Raising, P Smetana

Journal of the Department of Agriculture, Western Australia, Series 4

THERE has been increased interest in pheasant raising in Western Australia over the past few years, mainly as a result of more sophisticated eating habits and the associated restaurant boom, as well as farmers in country areas looking for more profitable sidelines.

An Evaluation Of Factors Affecting Establishment And Survival Of Russian Wildrye (Elymus Junceus Fisch.) On Foothill Ranges In Utah, Dale Lynn Drawe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several factors affecting establishment and survival of Russian wildrye were studied in the greenhouse and in the field.

Greenhouse studies conducted at Utah State University examined (1) the effects of competition on vigor and production of Russian wildrye, (2) moisture use by Russian wildrye and four weeds, and (3) effects of moisture level on emergence and seedling vigor.

During 1967 and 1969 at Tintic Valley field experiments were initiated to study effects on germination and seedling establishment of (1) seasons, (2) methods, and (3) intensities of seeding Russian wildrye. In 1968 and 1969 studies were made of phenology and root …

Seasonal Utilization Of Sago Pondweed By Waterfowl At Bear River Migratory Bird Refuge, Utah, Michael R. Sterling

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seasonal utilization of sago pondweed (Potamogeton pectinatus L.) by waterfowl was studied at Bear River Miqratory Bird Refuge by comparing amounts of sago production on a series of plots on Unit Four. One plot was available to carp and waterfowl; one only to carp; and one available to neither.

The cage used to eliminate carp and waterfowl use of a plot caused a significant increase in sago production. The increase was attributed to less turbidity and less wind and wave action within the cage.

Carp distribution was limited to deep-water portions of Unit Four, a small area, and …

The Role Of Agonistic Behavior In Regulation Of Density In Uinta Ground Squirrels (Citellus Armatus), Richard J. Burns

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agonistic behavior of ground squirrels was studied for two years in north-eastern Utah at an elevation of 6,300 feet. The main objective was to determine what role agonistic behavior had in regulating density in a population. All individuals in an unconfined population were trapped I marked I and observed from towers. Detailed data on behavior and density were recorded.

Though loss from a variety of factors occurred throughout the year I agonistic behavior had an important role in regulating the population at least twice during the year. In spring some squirrels I usually yearling males and late emerging yearling females, …

The Abundance, Migration And Management Of Mule Deer In Dinosaur National Monument, Robert W. Franzen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dinosaur National Monument, in northwestern Colorado and northeastern Utah, is comprised of 206,409 acres and contains several deer winter ranges. A need for deer studies developed because of winter deer mortality and deteriorating range conditions on some parts of the Monument.

Approximately 500 deer winter on the Yampa Bench and approximately 300 deer winter on the Island Park winter range. These are the two main winter ranges within the Monument.

Deer on the Yampa Bench migrated an average of 7.3 air miles to the south and summered on the Blue Mountain Plateau during the summer of 1966. This Plateau is …

Waterfowl Ecology And Utilization Of Uinta Mountain Water Areas, Steven Roger Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Waterfowl utilization was recorded by observing study units at different elevations from the time water areas were thawed in the spring until they were frozen in the fall.

Sixteen species of waterfowl were observed in the Uinta Mountain; mallards, green-winged teal, pintails, and ring-necked ducks were breeders.

Ninety-eight percent of all waterfowl observed were below 10,000 feet.

Waterfowl numbers were highest during migratory periods and lowest in the breeding season.

Adult waterfowl were observed most often on natural water areas and beaver ponds greater than one acre.

Water areas at lower elevations had high indices of aquatic invertebrates and contained …

The Influence Of Salinity On The Growth And Reproduction Of Marsh Plants, D. K. Kaushik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The water resources of the State of Utah are rapidly being developed for agriculture and industry. They are so extensively exploited that their continued and additional use must be justified on the basis of need and efficiency of utilization. To determine more accurately the quantity and quality of water needed to operate a marsh, a project was undertaken by the Utah Department of Fish and Game, the Engineering Experiment Station and the Cooperative Wildlife Research Unit at Utah State University. The study was divided into the two phases, one on quantity and one on quality of water. The present report …

Abundance, Movements, Harvest, And Survival Of Brown Trout And Mountain Whitefish In A Section Of Logan River, Utah, David W. Bridges

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Comprehensive population studies in the field of fisheries are in great demand. Many of our fishable waters are being changed, and we need to be able to predict the results of these habitat alterations. We must know how to include beneficial modifications in readjustments of habitat in order to create a fishery or prevent destruction of an existing one.

The acceptable situations for good fish production in large mountain streams are not well-known. A fishery can be properly managed only if the manager has sufficient knowledge of the carrying capacity of the habitat, the survival and mortality of the population, …

Farmers' Reactions Toward Upland Bird Hunting In Two Utah Counties, 1957, Frank J. Calkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Proof that public hunting on private lands is a growing Utah problem is, perhaps, most easily found by driving down any country lane. “No Trespassing" signs come one to a fence post or so it must seem to the pheasant hunter. His quarry is the most popular of Utah's farm game species and, unfortunately, the most popular subject of farmer-sportsmen disputes.

Reasoning that short seasons reduce hunter nuisances and property damage, landowners have long advocated three- to five-day pheasant seasons. And because of this and a former game department concern about overshooting the birds (Utah Fish and Game Commission, 1946) …

Selected Insecticides In The Control Of Invertebrates Possibly Associated With Avian Botulism, J. Larry Haddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Avian botulism or ''western duck sickness" has long been a major problem on duck marshes in the western part of the United States. This has been demonstrated to result from the ingestion of products of metabolism of bacterial cells of Clostridium botulinum type C. These products when ingested by waterfowl act as neurotoxins (Coburn, 1942). Studies have shown that many animal tissues are readily utilized as culture media by Cl. botulinum type C (Bell et al., 1955).

Since 1955 investigations have indicated a close relation between the occurrence of avian botulism and invertebrate population levels. It is thought that when …

An Introduction To The Ethology Of The Uinta Ground Squirrel (Citellus Armatus), David F. Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study describes behavior of the Uinta ground squirrel (Citellus armatus) in a free-living population. Its objective is to provide basic behavioral information on a small mammal which can fill in part of the gaps in our knowledge of behavior and social organization of the vertebrates. This would contribute to the long-term goal of viewing the progressive evolutionary changes in behavior from lower forms to man.

The Care Of The Breeding Sow, P C. Beck

Journal of the Department of Agriculture, Western Australia, Series 4

PIG-RAISING is a specialised field of animal production, which, to be profitable must incorporate both a scientific and a practical approach.

These two factors must be complementary, for without a sound practical approach, the value of the scientific principles involved, e.g., in breeding and compounding rations would accordingly be reduced.

The Airplane In Unit Sampling Of Mule Deer Populations In Harding County, South Dakota, Karl B. Kuhlmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The prairie deer region of South Dakota extends west from the Missouri River to the Black Hills. The region borders the states of Nebraska, Wyoming, Montana, and North Dakota, and is approximately 40,000 square miles in extent. Biologists believe that present deer numbers on these prairies are similar to those of pre-homestead days. The present large numbers of deer in certain counties have given many prairie ranchers and farmers cause for concern. The region's first deer season (bucks only) in 1952 resulted from earlier increases in mule and whitetail herds. After a closed season in 1953, a hunter's choice of …

Survey And Evaluation Of Big Game Exclosures In Utah, Stanford Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An "exclosure" is defined by Daubenmore (1940) as an experimental area which is protected from the activities of a particular class of animals by a barrier such as a fence or screen thereby controlling a single factor of environment, namely, the animal influence.

Several different types of exclosures are employed by the land management agencies in Utah. Small portable "paddocks" a few feet square are extensively used to gauge seasonal grazing pressure by livestock. Permanently fenced areas, ranging up to many acres in size, serve to demonstrate the effects of livestock use on the range. Another modification is the "big …

An Economic Evaluation Of Selected Treatments For Avian Botulism In Waterfowl On Utah Marshes, 1953-54, Donald A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Each year thousands of western waterfowl succumb to disease, predators, mechanical injury and other decimating factors . Based on a review of records it is conservatively estimated that an average of 25,000 ducks have succumbed to botulism on western marsh areas annually.

In a recent study, the United States Fish and Wildlife Service valued each duck and goose at $8.00 (McLeod, 1950). Applying this value to the estimated annual numerical loss, a total of $200,000 has been lost each season in mortality of western waterfowl from botulism. Control of this malady would reduce annual waterfowl and monetary losses.

Prevention and …

Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildlife management has been defined as lithe manipulation of wild populations of vertebrate animals in their relation to man and his interests" Wildlife management, then, could not exist in the absence ot either wildlife or humans. Converting this idea to the waterfowl situation, we can say that there are no waterfowl problems other than as they exist in the minds of men. (Wil1s, 1951) These words by the Chief of the IllinoIs Natural History Survey precede a plea for fundamental facts and a basic understanding of waterfowl upon which sound management can in turn be based. l"or only through sound …

The Status And Management Of Pheasant Posted Hunting Areas In Utah, William G. Parsons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since 1900 the ringneck pheasant Phasianus colchicus torquatus Gmelin has assumed major importance in the United states as an upland game bird. This is particularly evident in Utah where, in 1951, 76,000 hunters bagged an estimated one quarter million pheasants (8).

Some Of The Relationships Between Livestock Grazing And Duck Nesting In The Saltgrass Vegetation Type In Utah, Horatio W. Murdy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Little is known of the relationships between livestock grazing and duck nesting. This dearth of information occurs in spite of the fact that an understanding of these relationships is necessary in order to evaluate duck production on range land, and to formulate grazing policies for lands devoted to the production of ducks.

Recognizing the need for information on this subject, the Utah Cooperative Wildlife Research Unit and the Wildlife Management Institute jointly sponsored a study, during 1948-1949, of livestock grazing-duck nesting relationships in the saltgrass vegetation type in northern Utah. The study was financed by the Institute and supervised by …

A Survey Of Extension Work In Wildlife Management And The Development Of A Guide To Wildlife Extension Work In Utah, Edwin V. Rawley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The most efficient wildlife research programs and the most satisfactory methods of applying their results are greatly enhanced if the information is present in such an interesting and understandable manner that it becomes of practical value of the people. Extension education has the function of translating the results of research into usable form and presenting it to the people. The development of a wildlife extension program is based on the needs of the people, and the various phases of the program are designed to meet and solve wildlife problems confronting the people. The purposes of this study are: 1. To …

Biology Of The Boxelder Bug In Cache Valley, Arab Bakir Al-Tikrity

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The boxelder bug, Leptocoria trivittatue (say), is a hanipterous insect belonging to the family corisidae. Although it rarely is a pest of agricultural crops, its habit of invading homes and other buildings for hibernation and to warm itself has made it an annoying household pest. It has proven to be a difficult insect to control. Only a few of the contact insecticides, useful in control of related insect pests, have given satisfactory control of the Boxelder Bug. Because it has not been considered a critical problem, it has not received detailed attention from the scientific investigators. Its close association with …

An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turkey raising has become big business. During the period 1942 to 1946, the average annual return in Utah amounted to about nine and one-half million dollars (4). This amount would have been increased considerably if the death loss among poults had been lower. As an example, using the percentage of mortality given by Miner (9, p. 5), it is estimated that the death-loss of turkeys in 1944 resulted in a loss of gross income by the farmers of Utah of more than four million dollars provided that the price the farmer received had remained the same.

Among the prevalent causes …
