Structure And Petrography Of The Tertiary Volcanic Rocks Between Death Creek And Dairy Valley Creek (Box Elder Co.), Utah, E. Matthew Hare

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several volcanic flows lie between Death Creek and Dairy Valley Creek, near Etna, Utah. The major, central portion of the volcanic flows is composed of dacite and dacite vitrophyre. An elongate ridge in the southeastern corner of the study area and several small outcrops in Death Creek Valley are composed of rhyolite and rhyolite vitrophyre. Additional rock types include conglomerate, volcanic ash, and tuffaceous sedimentary rock of the Tertiary Salt Lake Formation, Paleozoic limestone, and Tertiary basalt.

Dacite and dacite vitrophyre samples are porphyritic, containing phenocrysts of plagioclase, quartz, biotite, amphibole, orthopyroxene, and iron-titanium oxides. Rhyolite and rhyolite vitrophyre samples …

Comparison Of Fishery Policies And Management Techniques Of The United States And Iceland, Ted I. Lillestolen

Marine Affairs Theses and Major Papers

In 1976, the United States enacted the Fishery Conservation and Management Act (FCMA), presently referred to as the Magnuson Fishery conservation and Management Act (MFCMA). The legislation is a complex and detailed document establishing for the first time a national fishery policy. The Act also created an organizational structure designed to implement this new policy. Since the Act's implementation, there has been a great deal of controversy, especially generated by the commercial fishermen. This paper focuses on Iceland, primarily because of its great economic dependency on its fisheries resources, unlike the United States.

The Aquatic Toxicity Of Organic Compounds To Embryo-Larval Stages Of Fish And Amphibians, Jeffrey A. Black, Wesley J. Birge, Willaim E. Mcdonnell, Albert G. Westerman, Barbara A. Ramey, Donald M. Bruser

KWRRI Research Reports

Aquatic toxicity tests were conducted on 11 organic compounds considered hazardous to water resources. The toxicity of each compound was evaluated using embryo-larval stages of two to eight fish and amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. The animal test species exhibited varying degrees of sensitivity to the selected toxicants. Combined frequencies for mortality and teratogenesis at 4 days posthatching gave LC₅₀ ranges of 3.66 to 8.25 mg/L for benzene, 1.16 to 22.42 mg/L for carbon tetrachloride, 0.11 to 1.20 mg/L for chlorobenzene, 2.03 to > 68 mg/L for chloroform, 3.01 to 5.56 mg/L …

Snares For Predator Control, Major L. Boddicker

Vertebrate Pest Conference Proceedings: 10th (1982)

The use of snares predates recorded history. The snare was first used when ancient man realized that an association between a tightening loop of vine and an ensnared animal was something which he could construct and repeat. The current increased interest in snares has been a result of restricted chemical tools in animal damage control resulting in a new look at old mechanical methods. The increased value of pelts of predators has brought efforts by private trappers to improve snaring as a tool. As a result, the ancient art of snaring has been greatly improved over the last decade. New …

Predator Problems When Using Sheep And Goats In Managing Brush On Rangelands, James E. Bowns

Vertebrate Pest Conference Proceedings: 10th (1982)

Rangelands occupy a large portion of the western United States and the world. Grazing by ruminant animals provides the only means of obtaining usable products from these lands. Sheep and goats are more efficient producers, better adapted to many ranges, and are useful in controlling or manipulating shrubs and other undesirable vegetation which results in improved range conditions and increased water yields. There has been a general decline in sheep and goat numbers and a shift toward cattle. Predation has been a major factor in the abandonment of many sheep and goat operations and the shift to other livestock. A …

Rodent Problems Relative To Mechanical Harvesting, A. Charles Crabb, Ronald L. Riddle

Vertebrate Pest Conference Proceedings: 10th (1982)

As the number of crops that are mechanically harvested increases, the reports of rodent problems associated with those crops increase also. This report examines the rodent problems in mechanically harvested tomatoes and reports on work done in studying the effects of various border crops on rodent populations. It also looks at possible rodent management options available to growers of mechanically harvested crops.

Pulsed Baiting —A New Technique For High Potency, Slow Acting Rodenticides, Adrian C. Dubock

Vertebrate Pest Conference Proceedings: 10th (1982)

The disadvantages of the acute, fast-acting, rodenticides are well understood by the specialist. However, despite poison-shyness and consequent short-lived, low efficacy rodent control, many users prefer "acutes" such as zinc phosphide to "first-generation" anticoagulants of the warfarin type. The techniques necessary for efficient use of the first-generation anticoagulants are often inappropriate, particularly in agriculture. High labour and bait inputs required are unacceptable and are, together with the need for area coordinated control programs, significantly responsible for lack of widespread use of anticoagulants, even in those countries with a long history both of disastrous rodent damage to crops and rodent damage …

The Cliff Swallow—Biology And Control, W. Paul Gorenzel, Terrell P. Salmon

Vertebrate Pest Conference Proceedings: 10th (1982)

Cliff swallows (Petrochelidon pyrrhonota) nesting in colonies on man-made structures can cause aesthetic problems and health hazards. Cliff swallows are migratory, wintering in South America and breeding throughout most of North America. Cliff swallows have a homing tendency to old colonies and are attracted to the gourd-shaped mud nests. Egg laying begins before nest construction is finished; clutch size averages 3 or 4 eggs. Re-nesting is common if a nest fails and some pairs may raise 2 broods in 1 nesting season. Cliff swallows may be present at a colony for up to 132 days. Cliff swallows are protected by …

A Tiger Problem In India, Walter E. Howard

Vertebrate Pest Conference Proceedings: 10th (1982)

During the past decade, India has done wonders in re-establishing populations of rare and threatened wildlife. Project Tiger, initiated in 1973, has stimulated a successful conservation movement in India. But tigers, like all animals, do not recognize man's property lines and, as populations increase in the forest reserves, more and more tigers forage outside of the parks, killing livestock and people. The current methods and regulations of dealing with troublesome tigers (and elephants) that stray from the sanctuaries due to overpopulation social pressures, lack of food, old age, or other reasons may soon become inadequate as the value of human …

Twentieth Anniversary Of Vertebrate Pest Conferences In California, Walter E. Howard

Vertebrate Pest Conference Proceedings: 10th (1982)

It is difficult for some of us to realize that the Vertebrate Pest Conferences in California were started 20 years ago. We have come a long way since the first one in Sacramento in 1962 to the very successful 3-day Tenth Vertebrate Pest Conference (VPC) opened by Chairperson Rex E. Marsh on 23 February 1982, in Monterey, California. When closing the Tenth Conference, incoming Chairperson for the 1984 VPC, Dell 0. Clark, pointed out that there were easily 550 people in attendance from 31 states, District of Columbia, and 15 foreign countries.

The Urban Coyote Problem In Los Angeles County, Robert G. Howell

Vertebrate Pest Conference Proceedings: 10th (1982)

Extensive, urban development of hillside areas in Los Angeles County has created an undesirable human interface with coyotes (Canis latrans). Plentiful, readily available household garbage, pet foods, and water have spawned abnormal numbers of bold coyotes that have adopted residential properties and the human environment as ideal habitat. Consequently, at least six persons have been attacked, including the death of a three-year old child, during the past three years. Selective use of padded steel traps, shooting, and public education are presently being used in problem areas by the Agricultural Commissioner in an attempt to reindoctrinate these predators into returning to …

Problem Vertebrate Management In Zimbabwe, Mike J. F. Jarvis, Mike La Grange

Vertebrate Pest Conference Proceedings: 10th (1982)

Zimbabwe is the second largest agricultural producer in Africa and is responsible for the regional food security plan of the Southern Africa Coordination Conference member countries (SADCC). Problem vertebrate management and research is an important function of the Department of National Parks and Wildlife Management, which is also responsible for conservation of natural resources in national parks. The country still contains large populations of wildlife species that at times conflict with man and his agricultural interests. Problem vertebrates and methods of control are briefly outlined.

Rodent Repellents For Planted Grain, Ron J. Johnson, Ann E. Koehler, Orvin C. Burnside

Vertebrate Pest Conference Proceedings: 10th (1982)

Thirteen-lined ground squirrels (Spermophilus tridecemlineatus) and other small rodents damage corn (Zea mays) stands by digging and consuming planted seeds and young seedlings, particularly in reduced-tillage fields. The use of reduced-tillage systems such as ecofarming provides greater dryland crop yields, conserves moisture, reduces soil erosion and provides suitable habitat for ground-nesting birds. The habitat available in these fields also allows various species of rodents to thrive. Reduced-tillage farming is expected to increase markedly in the years ahead; thus, rodent problems will increase as well. Seed repellents offer a promising and cost-effective method of controlling rodent damage to planted corn in …

A Review Of The Secondary Poisoning Hazard Potential To Wildlife From The Use Of Anticoagulant Rodenticides, Dale Kaukeinen

Vertebrate Pest Conference Proceedings: 10th (1982)

The utility and characteristics of the family of anticoagulant rodenticides are reviewed, including the new members difenacoum, bromadiolone and brodifacoum. General considerations are given in investigating the likelihood of nontarget poisoning with rodenticides. The literature dealing with secondary poisoning studies and concerns with the use of anticoagulant rodenticides is reviewed. The utility of laboratory toxicity data versus field-generated exposure data is compared. Considerations of secondary poisoning by anticoagulants are reviewed as regards parameters such as specific predator-prey systems, biotopes, rodenticide use patterns, and risk-benefit assessments. Finally, examples of appropriate field studies proposed to assess specific secondary poisoning risk situations associated …

Pigeon Control: An Integrated Approach, Colleen M. Martin, Lee R. Martin

Vertebrate Pest Conference Proceedings: 10th (1982)

Reducing a pigeon population to a tolerable or minimal impact level is a subject about which one can find much antiquated and impractical information. Most technical literature reports on the biology of pigeons and associated disease factors. The intention of this paper is to describe the practical application of large-scale pigeon population reduction programs that have been at least 90% effective in 45 out of 46 cases over the past four years. Human relations, exclusion, trapping, toxic perches and Avitrol are discussed.

Traditional Approaches For Protecting Cereal Crops From Birds In Africa, P. Ruelle, R.L. Bruggers

Vertebrate Pest Conference Proceedings: 10th (1982)

Despite the recent emphasis in Africa by national and regional plant protection organizations to control pest birds, traditional farmers usually are still left to their own initiative, as they have been for centuries, to protect their crops. These farmers employ many ingenious visual and oratory frightening techniques, barriers, agronomic planting or harvesting modifications, and bird population-suppression methods. Under some circumstances these methods can reduce damage. However, their effectiveness is subject to such variables as the season of the year, the type and maturation stage of the crop, the pest species and its abundance, the size and ownership of the field, …

Mountain Lion Predation On Domestic Livestock In Nevada, H. Russell Suminski

Vertebrate Pest Conference Proceedings: 10th (1982)

The mountain lion has long been considered a serious predator on domestic livestock, primarily sheep, in the state of Nevada. For the past five years (FY77-81), documented losses to lions have averaged 375 animals. While this number is not large, most losses are sustained by only a few individual livestock operators, and the losses constitute a serious economic hardship for these individuals. An average of 23 lions have been taken in response to livestock depredation complaints during each of these five years. Controlling livestock loss to mountain lions is the responsibility of the Animal Damage Control branch of the U.S. …

The Use Of Fences For Predator Damage Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 10th (1982)

The development of exclusion fencing has been extensive in Australia in attempts to reduce losses of crops and livestock to rabbits (Oryctolagus cuniculus), dingos (Canis familiaris Var. dingo) and other species. Restrictions on other damage control methods have led to increased efforts in the United States to utilize such fences for protection of crops and livestock from dogs (Canis familiaris), coyotes (Canis latrans) and other species. Electric fences have occasionally been used to protect apiaries from black bears (Ursus americanus) and to protect some wildlife species from carnivores. Varied fence types include conventional net-wire or combinations of net and barbed …

Bird Problems And Their Solutions In Britain, Ernest N. Wright

Vertebrate Pest Conference Proceedings: 10th (1982)

The background and organization of research on bird pests in Britain are described and the main projects are outlined. Work is currently concentrated on bullfinches, starlings, rooks and woodpigeons together with behavioral studies aimed at developing better bird scarers.

A Comparison Of Selected Rodenticides For The Control Of The Common Valley Pocket Gopher (Thomomys Bottae), Barry R. Tickes, Lloyd K. Cheathem, John L. Stair

Vertebrate Pest Conference Proceedings: 10th (1982)

The common valley pocket gopher (Thomomys bottae) has become a serious agricultural pest in certain regions of the Lower Colorado River Basin. The mechanical burrow-builder is the most economical and effective method of controlling this pest although many growers and some researchers have reported less-than-satisfactory results when using this technique with currently available rodenticides. Six formulations of three toxicants including strychnine, zinc phosphide and diphacinone were applied with the burrow-builder to assess their efficacy. Results indicated that negligible control is achieved with 0.35 and 0.5% strychnine although these are the most commonly used formulations in Arizona. Diphacinone also produced negligible …

Data Flow Program Graphs, Alan L. Davis, Robert M. Keller

All HMC Faculty Publications and Research

Data flow languages form a subclass of the languages which are based primarily upon function application (i.e., applicative languages). By data flow language we mean any applicative language based entirely upon the notion of data flowing from one function entity to another or any language that directly supports such flowing. This flow concept gives data flow languages the advantage of allowing program definitions to be represented exclusively by graphs. Graphical representations and their applications are the subject of this article.

Conductance In Restricted-Dimensionality Accumulation Layers, A. B. Fowler, A. Hartstein, Richard A. Webb

Faculty Publications

Conductance has been studied in metal-oxide-silicon field-effect transistor accumulation-layer samples in which it is possible to constrict the channel to small dimensions both perpendicular to the surface and perpendicular to the channel. A temperature-dependent conductance σ=σ₀exp[-(T₀/T)ⁿ] is observed, where n=1/2 for small channel widths and n=1/3 for larger channel widths. It is believed that this behavior arises from a transition from one-dimensional to two-dimensional variable-range hopping in the sample.

A Theory Of Small Program Complexity, Kenneth I. Magel

Computer Science Faculty Research & Creative Works

Small programs are those which are written and understood by one. person. Large software systems usually consist of many small programs. The complexity of a small program is a prediction of how difficult it would be for someone to understand the program. This complexity depends of three factors: (1) the size and interelationships of the program itself; (2) the size and interelationships of the internal model of the program's purpose held by the person trying to understand the program; and (3) the complexity of the mapping between the model and the program. A theory of small program complexity based on …

Traditional Small Craft: Motivations For Renewed Interest, Ruth Ann Boragine

Marine Affairs Theses and Major Papers

The revival of interest in traditional small craft during the past decade is evidenced in the growth of related associations, museums, and publications and is shown to be reflective of much broader socio-cultural trends. No study has yet been done, however, to determine what motivates the interest of small craft enthusiasts. Are they athletes, retired people, cruising boat owners, or craftsmen? Can they be defined by income level or occupation?

These questions, among others, are addressed through analysis of an interest survey which was distributed randomly to members of two Newport, Rhode Island, yacht clubs, and also to attendants at …

A Preliminary Assessment Of Nutrient Loading Into Narragansett Bay Due To Urban Runoff, Lynne Carter Hanson

Marine Affairs Theses and Major Papers

This study is a component of a more comprehensive investigation at the Marine Ecosystems Research Laboratory, (MERL), University of Rhode Island, that was undertaken in order to assess the potential for eutrophication in both its meanings as a natural and man-induced process occurring in the upper portions of Narragansett Bay and its watershed. This assessment required identification and quantification of the various inputs in order to establish the annual loading and eventual effects of the four important nutrients; ammonia, nitrate-nitrite, silicate and phosphate.
