An Ecological Life History Of Budsage In Western Utah, Benjamin W. Wood
An Ecological Life History Of Budsage In Western Utah, Benjamin W. Wood
Theses and Dissertations
The ecological life history of budsage (Artemisia spinescens D.C. Eaton) was investigated during 1963 and 1964. The field studies were conducted at the Desert Experimental Range in Millard County, Utah. Laboratory studies were done at Brigham Young University. The different community types in which budsage grows were described and the physical site factors, viz. climate, soil texture, total soluble salts, hydrogen ion concentration of the soil, carbonate content and soil moisture were investigated. Phenology of seedlings, root systems, shoot and flower development, and plant longevity were investigated. Studies were also made on the effects of different seasons and intensities of …

Salix In Utah, Alv Dan Youngberg
Theses and Dissertations
This thesis is a study of the native and naturalized species of Salix in Utah, and is based upon the following methods. A review of all available literature was accomplished in order to compile a list of species. Type specimens were obtained from the University of California at Berkeley, the Smithsonian Institution, and the Gray Herbarium of Harvard University, University of Utah, and Utah State University. About five-hundred specimens were collected in twenty counties during the fall fo 1965 and the spring of 1966. The identification of the willows in this study was based upon type specimens, annotations by Carleton …

An Evaluation Of Pricing Practices And Their Effect On The Egg Industry In Utah, Wilbur N. Sherman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The decade from 1953 to 1963 was one of drastic change for the egg industry in Utah. A study conducted at Utah State University shows that in 1952, slightly more than 40 percent of local egg production was s old in distant markets while in 1964, import data gathered from egg handlers in the State indicate that 20 to 25 percent of the eggs consumed in Utah were imported.
The Economic Value Of Forage For Livestock On Public And Private Ranges In Utah, Mardell D. Topham
The Economic Value Of Forage For Livestock On Public And Private Ranges In Utah, Mardell D. Topham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The United States Government controls about 359 million acres of land in the 11 Western States. This vast acreage produces recreation for vacationers, timber for lumbermen, water for city and rural consumption, forage for livestock and wildlife, and minerals for miners. In many cases, the users of these products are competing and are clamoring for a large share of this land. Consequently, land use is continually changing. Since 1941, the amount of timber cut has tripled, recreation has doubled, watersheds now yield a better quality of water (Clawson, 1957), forage for wildlife has increased but forage for livestock use has …

Behavior Patterns Of The Adult Alfalfa Weevil In Cache Valley, Utah, J. Wanless Southwick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The alfalfa weevil, Hypera postica (Gyllenhal), was first found in the United States in Salt Lake City, Utah, during 1904 (Titus, 1910b). It spread form this point of original introduction and partially infested Cache Valley by 1912 (Titus, 1913).
Some Economic Effects Of Irrigation Water Pumping From A Declining Water Table In The Milford Area Of Utah, Duane R. Price
Some Economic Effects Of Irrigation Water Pumping From A Declining Water Table In The Milford Area Of Utah, Duane R. Price
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Surface water is found in very limited quantities in most of southwestern Utah. In order to compensate for a deficit of surface water it has been necessary to use underground water where it is possible and profitable to do so. The Milford pumping area in southwestern Utah is an area where expanded irrigated agriculture has been established by pumping of ground water. It is one of four major pumping areas in the state of Utah.
The Comparative Costs Of Processing Frozen Sour Cherries, Utah County, Utah, 1964, Richard K. Hart
The Comparative Costs Of Processing Frozen Sour Cherries, Utah County, Utah, 1964, Richard K. Hart
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Since 1905 when Professor Henry C. Taylor opened the area of economies of scale for discussion with his observations on the variables affecting farm size, agricultural economists have been concerned with scale of plant in agriculture. Considerable study and discussion have not resolved many of the questions raised in this area, but a basic framework has been constructed which can be used as a planning tool in the efficient organization and operation of plants of various sizes under given conditions.
The Weberian Osteology Of Three Utah Suckers (Catostomidae), William James Stubbs
The Weberian Osteology Of Three Utah Suckers (Catostomidae), William James Stubbs
Theses and Dissertations
The Weberian mechanisms of three Utah Lake suckers (Catostomidae: Catostominae; Catostomini), Catostomus fecundus Cope and Yarrow, Chasmistes liorus Jordan, and Catostomus ardens Jordan and Gilbert, were examined, described, and compared, and a statistical analysis was made of some of their more important differences. The mechanisms were found to be basically similar to one another and to those of other Catostomini as previously described and/or illustrated. They are individually distinct, but each varies within its own limits, the intraspecific variation being greatest in the wider-ranging Catostomus ardens and least in the seemingly most restricted Catostomus fecundus. From the evidence at hand …
Dermacentor Andersoni And Rocky Mountain Spotted Fever In National Forest Recreational Sites Of Utah, C. Selby Herrin
Dermacentor Andersoni And Rocky Mountain Spotted Fever In National Forest Recreational Sites Of Utah, C. Selby Herrin
Theses and Dissertations
The objectives of this study were to determine (1) the prevalence of adult ticks of Dermacentor andersoni in national forest recreational sites of Utah, and (2) the incidence of spotted fever rickettsia, Rickettsia rickettsii, in the ticks of these areas. With the use of a white flannel cloth, 358 adult D. andersoni (135 males and 223 females) were collected from 48 recreational sites during the spring and summer of 1964. Ticks from each collection were put in pools, preserved in non-fat skim milk at -30° C, and subsequently tested for the presence of spotted fever rickettsia by guinea pig inoculations. …
Meadow, Millard County, Utah: The Geography Of A Small Mormon Agricultural Community, Richard H. Jackson
Meadow, Millard County, Utah: The Geography Of A Small Mormon Agricultural Community, Richard H. Jackson
Theses and Dissertations
The agricultural village was the basis of the original economy of Utah established by the Mormon settlers, but it has since been supplanted in importance by the industrial and commercial activities of the large centers of the Wasatch Front counties of Salt Lake, Weber, and Utah. This study was conducted in an attempt to determine the future of those communities removed from industrialized northern Utah. The village of Meadow, Millard County, was chosen as an example and it was subjected to a detailed geographic analysis. From this analysis conclusions have been drawn regarding its future.
