Relationship Of Certain Environmental Factors To Benthic Fish Densities In Bear Lake, Idaho-Utah, Thomas J. Hassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The project was initiated in June of 1958 and financed by the National Science Foundation and the Wildlife Management Department of Utah State University.

The broad aspects of the study were to determine if a relationship exists between certain physical and biological factors and benthic fish densities. The project vas divided into two parts: (l) to determine the time and extent of thermal stratification, zooplankton densities, conductivity changes within the lake and conductivity differences between the lake and its tributaries; (2) to determine it a relationship exist between benthic fish densities, temperatures, depths, conductivities and benthic zooplankton densities. The data …

Limnological Studies On Hyrum Reservoir, In Northern Utah, Royal A. Rich

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With an ever increasing fishing pressure on our natural and artificial lakes every measure possible must be taken to preserve the sport for its many thousands of participants.

Hyrum Reservoir is easily accessible to the fishermen of northern Utah. In recent years the lake has offered little in the way of fishing. It is hoped that the information accumulated in this study will help pave the way to a successful stocking program and that Hyrum Reservoir will be one of the productive fishing areas available to Utah anglers.

The objectives of this investigation were:

1. To determine the extent of area …

The Effect Of Feeding Various Levels Of Fluoride To Dairy Cattle On Their Pepsin Activity, Hassan Sabeti-Rahmati

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In certain industrial areas fluorides are present in various amounts in the atmosphere. These fluorides are liberated by industrial processes at high temperature in treatment of materials containing fluoride, either as a natural impurity, or as added material for technical purposes. Equipment and procedures have been installed in many plants to reduce the output of fluorides significantly, yet forage and hay grown near the plants may contain elevated amounts of fluorides. The feeding of such material to young livestock for many months may cause fluorosis or chronic fluoride poisoning. Some springs contain a high concentration of fluorides and the continuous …

A Study Of Hot Brine Treatment In Making Cheese From Antibiotic Milk, Robert E. Howe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The cheddar cheese industry is continually confronted with the problem of manufacturing cheese from milk in which tile acid development is slow or non-existent. In recent years, many antibiotics have been used as a treatment for mastitis. Penicillin, streptomycin, and aureomycin are some of the more prominent antibiotics used for this purpose.

Life History Notes On The Walleye, Stizostedion Vitreum Vitreum (Mitchill) In A Turbid Water, Utah Lake, Utah, Billy B. Arnold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early in 1952, walleye fry were stocked for the first time in Utah Lake. Subsequent plants were made in 1954, 1955 and 1956. Altogether, over two million fry have been stocked.

By January, 1958, it was felt sufficient time had elapsed for the species to establish patterns of growth, reproduction, food habits and consequent relationships to the new environment. Thus, on January 1, 1958, a Federal Aid to Fisheries project, number DJ F-4-R-5, job T, was initiated. This project was entitled "investigations of Yellow Pikeperch and Channel Catfish of Utah Lake, Utah County." Although the closing date was December 31, …

Studies In Iron Chlorosis Of Leaves, Narayan Gunderao Perur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Normal healthy growth and development of plants is controlled by certain factors known as factors of plant growth. They are soil, climate, and plant inheritance. The soil contains many nutrient elements needed by plants both in macro and micro quantities. Iron is one of the essential elements required by plants in small amounts.

When plants are starving for any of the essential nutrients, characteristic symptoms usually appear as certain abnormalities, discoloration and deformation of leaves, fruits, and other parts. The deficiency symptoms, though not easily recognizable in some cases at the beginning, are quite apparent in advanced stages of plant …

A Political Study Of Federal Aid To Education At Utah State University, Richard Yates Merrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the present-day world of change, every time we pick up the paper we read of something new in our society. We now have new rockets, new satellites, new computers, and new methods or destruction. There are also many "new" things in the field of education. One of these is federal aid to education. As yet, there seems to be no consensus on the merits of this supposedly new approach to educational finance. Some view it as a kind or plague; others see it as an unmixed blessing. Actually, federal aid to education is quite old and quite common.

A Comparison Of Daughters Of Sires In Artificial Breeding At Different Levels Of Management, Richard C. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the largest problems facing the successful dairyman of today is selection of proper sires to mate to his high producing cows. Many breeders and dairymen have the impression that proven sires will give the same increase in production regardless of the dam's production or the level of environment present. Even though sires come from high producing herds, some as high as 600 pounds of butterfat, the average production of all cows in the state of Utah remains at a much lower figure. The average for all cows in Utah is about 250 pounds of butterfat and the average …

Interaction Of Riboflavin With Molybdenum, Jacques Tocatlian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum may function as a catalyst in promoting and controlling some of the complex chemical reactions that go on in living systems. The lack of understanding which exists about these reactions is due to their obvious complexity and to the extremely minute quantities of molybdenum involved. Traces of molybdenum have been shown to have spectacular results on the growth of plants when added to certain soils. This metal is also required for the growth of azobacter, the nitrogen-fixing bacteria (1).

Molybdenum has been shown to be present in four enzymes: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4) and aldehyde …

Observations On The Life History Of Channel Catfish, Ictalurus Punctatus (Rafinesque) In Utah Lake, Utah, Robert E. Lawler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The channel catfish, Ictalurus punctatus (Rafinesque), was first introduced into Utah Lake in the summer of 1911, and has since been stocked in the lake on numerous occasions. It has only been in the last few years that the channel catfish has become an important game fish in Utah. As the value of the channel catfish, as a game fish, increased, it has become increasingly important to the state to maintain this species for present and future generations. This study was initiated in 1958 and completed in 1960, and was financed by the Utah State Department of Fish and Game. …

The Effects Of Flouride Ion On Some Blood Constituents Of Rainbow Trout, Salmo Gairdneri, Linnaeus, Richard H. Alger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past quarter of a century there has been considerable investigation into the effects of fluorides on living organisms. It has been well established, as a result of these studies, that both small and elevated amounts of fluorides present in the environment may have a marked toxic effect upon gaining entry into the organism. Much of the research involving fluorides and the living organism has been confined to experimentation with animals, although considerable evidence indicates that plants are also subject to injury if fluorides are present in the atmosphere or the soil.

The great majority of the research dealing …

A Morphological Description Of The Trichomonad Found In The Stomach Of Swine, Floyd M. Caskey

Biology

As far as is known, no morphological study of the stomach trichomonads of swine has been made. The majority of investigators have assumed that the trichomonads found in the cecum and stomach are identical. It has been reported that the nasal form is different from that of the cecum and that the nasal form is simlar to Trichomonas foetus. The relationships among the trichomonads from these three locations have yet to be determined.

Comparison Of The Influence Of 17-Hydrocortisone And 2-Methyl 9a-Fluorohydrocortisone Acetate On The Involution Of The Thymus Gland In Mice, Gerald K. Wallace

Biology

Previous studies have shown that the adrenal cortical hormones play an important part in lymphatic tissues physiology. Several authors have demonstrated alterations in blood leukocytes and decreased thymus weight following administration of extracts or purified preparations of adrenal cortical hormones. For this reason the thymus gland weight and lymphocyte response have been used as a method of determining activity of several of the corticoids.

The Influence Of An Artificial Medium Upon The Morphology Of Swine Cecal Trichomonads, Charles P. Hibler

Biology

As yet no thorough studies of the trichomonads living in the cecum of swine have been made. In fresh preparations the trichomonads from the nose, stomach, and cecum appear distinct. After a period of cultivation In an artificial medium, however, the flagellates from the cecum became morphologically similar to the cultured porcine nasal and stomach trichomonads. The cultivation of the trichomonads from the cecum apparently results in either a morphological change in the trichomonad or in a selection among different species or types present in the cecum.

The Effect Of Copper And Iron Salts On The Expression Of Eye Abnormalities And Melanotic Tumors In Different Stocks Of Drosophila Melanogaster, J. Howard Turner

Biology

Phenotypes in Drosophila can be altered by subjecting the developing larvae to environments containing an exess of heavy metal salts (34, 36). Such alterations, which resemble the effects of mutant genes but are not inherited, have been called phenocopies. The mechanism through which the phenocopy is produced may suggest a process through which a mutant gene influences a phenotype. In cases where such parallels are drawn, it is assumed that a mutant gene and an environmental agent have a similar effect on a particular step in an established metabolic pathway. It would seem less likely but not impossible for the …

Studies In Transmission In Ovine Vibriosis, William H. Rose

Biology

Vibrio fetus, Smith and Taylor, is the principle etiological agent of ovine infectious abortion in the United States. During the 1952 lambing season, the lamb abortions were estimated at 50,000 in Colorado, 30,000 to 40,000 in Idaho, and from 10,000 to 15,000 each in Utah and Wyoming. A conservative estimate of premature lamb losses due to V. fetus infections in the western states for this year was 100,000. In infected flocks the incidence of mortality in aborting ewes may be as high as 10 percent. Since 1952 the incidence of vibrosis among sheep has remained high.
