Phenotypic Expression And Genetic Analysis Of A New Drosophila Melanogaster Mutant (Eyes-Reduced) Exhibiting A Structural Eye Abnormality, James W. Edwards

Biology

During experiments involving the addition of copper sulfate to the food medium (Turner, 1959), some flies from the tu¹⁵⁰/Cy strain of Drosophila melanogaster exhibited a structural eye abnormality. By inbreeding those flies a new mutant stock was developed. Phenotypically the flies of this new stock resembled the established fourth chromosome eyeless mutants of D. melanogaster, and the new mutant was tentatively designated as eyeless-prime (ey'). Turner described the morphology of ey', and he also superficially investigated the genetic basis of the trait. The purpose of this investigation was to locate the genes associated with …

Bear Lake And Its Future, William F. Sigler

Faculty Honor Lectures

Even in such a wide-ranging and eternally changing field as biology, a few statements about certain aspects can be made with a minimum likelihood of their being refuted. In this class are the following: No two lakes are identical. Any given lake is simultaneously many things to many people. A lake is never static. The influence of a lake reaches far beyond its shores.

Bear Lake, Utah-Idaho, can be used to good advantage to exemplify the truth of these statements. It defies meaningful comparison with other lakes unless a mass of detailed statistics is employed. To the fisherman and water …

A Study Of The Relationship Of Potassium Accumulation To Metabolism In A Sodium Rich Yeast, Thomas H. Strunk

Biology

Physiological phenomena such as glandular secretion, intestinal and tubular absorption, nervous activity and bioelectric potentials are all closely related to the movement of sodium (Na) and potassium (K) across cell membranes. The movement of the ionic forms of Na and K across biological membranes has been of special interest to investigators because the movements fail to conform to the predictions of diffusion and thermodynamic law (35). This behavior has been referred to as active transport when the following conditions are met: i) the transport exceeds or is opposite to that to be expected from electrochemical gradients; ii) the transport depends …

The Entomological Aspects Of Seed Chalcid Bruchophagus Roddi Gussakovsii Resistance In Alfalfas, Wayne A. Rowley

Biology

The alfalfa seed chalcid has been recognized as an important pest of alfalfa seed since 1891 (Urbahns, 1920). Heavy concentrations of seed chalcid in the alfalfa seed producing regions of the western United States pose a serious threat to the production of alfalfa seed. Experiments designed to study bionomics and plant resistance of this pest are part of a regional project at the Experiment Stations of many western universities. Several states and workers are testing a number of chemicals for possible use in controlling the alfalfa seed chalcid.

Biology And Control Of The Rose Stem Girdler, Agrilus Rubicola Communis Obenb., On Raspberry, Nuggehalli N. Raghuvir

Biology

The first red raspberries were cultivated in Europe 400 years ago. They were grown for the first time in the United States some time before 1800 (Gourley and Howlett, 1941). The cultivation of raspberries is limited largely to the northern part of the United States, chiefly in the cool, temperate areas. Areas from which extensive quantities of red raspberry are shipped are located in southern New Jersey, in the Hudson river valley, in western Michigan, in the Puyallup valley of Washington, and near Sebastopol, Washington.

A Study Of Sprinkler Uniformity Evaluation Methods, Baha Dabbous

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water in homes, on farms, by factories, and for recreational purposes has been increasing rapidly. Water use has doubled in the last three decades. By 1980, water use is expected to be double the current use. In arid and semi-arid regions, the practice of successful profit-yielding agriculture often depends on irrigation. Irrigation is, in turn, dependent upon a water supply which is limited. The highest possible efficiency should be maintained if maximum utilization of the available water resources for irrigation is desired. Sprinkler irrigation allows, among other things, high water application efficiencies with good distribution uniformities.

The Effects Of Radium On Certain Goldfish Blood Constituents And Organs, D. Wayne Linn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background radioactivity from radium has long existed in ground and surface waters of the United States, but in the last 15 years radium has become a consequential unnatural contaminant of waters (Coulomb, 1955; Rone, 1952; Schlundt, 1910; Scott and Barker, 1956; Scott, 1961; and Tsivoglou et al., 1958). The onset of the atomic age initiated the increased processing of uranium ore for its uranium content. Radium is a daughter product and a by-product of uranium ore and its purification (Glasstone, 1958; and Tsivoglou et al., 1958). The uranium refinery wastes are released into streams in which all forms of aquatic …

Effect Of Sweeteners On The Acceptability Of Selected Processed Fruits, Richard Lee Mclaughlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1959 Abbott Laboratories estimated (3) that every year 60 million persons go on controlled diets. Of these about 34 million have serious obesity problems, 3 million are diabetics and the rest have disorders that demand strict dietary measures.

Factors Affecting The Waterfowl Hunter Utilization And The Waterfowl Kill At The Bear River Migratory Bird Refuge, 1960-61, Stephen V. Goddard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1960 there were 1,955, 000 waterfowl hunters in the United States. These hunters spent $89,431, 000 (an average of $45.74 per individual) and 15,158, 000 hunter days in the field. The hunting population will increase 35 percent by 1975 (Anonymous, 1960).

The large increase in hunters will bring a proportional increase in the demand for places to hunt. Many states face the problem of providing enough public hunting for such an army of sportsmen. Studies by Kozlik (1958) in California, Gordinier (1957) and Friley (1959) in Michigan, and Bednarik (1957, 1961) in Ohio point out some of the problems …

Biochemical Studies On The Effect Of Fluoride On Higher Plants, Shang-Fa Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluoride occurs naturally in plants, but its presence has attracted attention primarily in certain industrial areas where concentrations are elevated above normal by accumulation from the atmosphere. Certain plant species have been observed to be injured as a result of accumulation of excessive fluoride from the atmosphere. The general symptoms of fluoride injury are necrotic lesions and burning which appear first in the leaf tips and margins.

An Evaluation Of Antibiotics Upon Selected Dairy Organisms, Roy Brog

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to answer a three-fold purpose. Primarily, it has endeavored to measure the inhibitory effect of three antibiotics (potassium pencillin, dihydrostreptomycin, and oxytetracycline) on lactic acid producing organisms. The lactic acid-producing organisms include Streptococcus lactis, Streptococcus thermophilis, and Lactobacillus bulgaricus.

The determination of an effective dose of a given antibiotic which will inhibit 50 percent of the lactic acid-producing organism (E.D.₅₀) will be established. A 50 percent cut in acid development will certainly lead to an inferior product.

The secondary purpose has related to the detection of inhibitory substances (antibiotics) in milk. What is …

An Evaluation Of Social Stars, Regulars, Neglectees, And Isolates In Ability-Grouped And Random-Grouped Classrooms, Benjamin W. Standing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education in the United States attempts to present maximum opportunities for learning in a democratic atmosphere. Many great educators have sought means to accomplish this end. Today, because of the stimulating force of other nations, even greater pressure is being brought to bear to achieve these goals. The plan of grouping pupils according to their abilities has been presented as one way to facilitate learning.

Ability grouping is the assigning of pupils who are essentially alike to special grade levels and to parallel sections of the same grade. Although it may be thought that ability grouping is a new procedure, …

A Comparative Analysis Of The Effects Of Heterogeneous And Homogeneous Elementary School Grouping Practices On Selected Personality Variables, Clarence D. Swaner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relative advantages or disadvantages associated with the practice of grouping school children according to ability level has long been the subject of considerable discussion among educators. The general tendency has been for educators to divide into two camps: Those who expound the various merits of homogeneous grouping, and those who favor and support heterogeneous grouping practices. Less common, but acknowledged, are those educators who favor a combination of the two methods. Research dealing with the relative value of either method has usually been concerned with only one aspect of the problem--that of academic achievement. However, the efforts of several …

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 …

Ecology Of Spring Fed Salt-Marshes, Eric George Bolen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any marsh is a distinctive land-form of varied interest. To the agriculturist it is wasteland to be reclaimed; to the naturalist, a habitat of aesthetic value. To the ecologist, however, a marsh represents a complexity of vegetation under the influences of many and often inseparable factors. It becomes a place of challenging study.

Complexing Of Sugars And Polyhydroxy Alcohols With Molybdenum (Vi), Su Chin Kiang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum is very important in the life processes of both plants and animals. It acts as a catalyst in promoting and controlling many biological reactions in living cells, but exactly what it does and how it functions are not well understood. In the past because of the obvious complexity of the reactions concerned and the extremely minute quantities of molybdenum involved, its presence was long undetected. Lately, molybdenum has drawn special attention on account of its effects on metabolic processes, particularly of plants. In this regard, molybdenum has been shown to be present in four enzymes: nitrate reductase (JJ), xanthine …

Molybdenum Chelates Of 8-Hydroxyquinoline-5-Sulfonic Acid, Ellis Ray Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Man has had an intense interest in the role of enzymes in biological reactions for many years. The basic question -- how enzymes are able to function so efficiently -- remains as yet largely unanswered.

Only in recent years has it been discovered that molybdenum is essential for certain biological processes. For example, traces of molybdenum added to certain soils have resulted in spectacular plant growth (1). Four enzymes are known to contain molybdenum: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4), and aldehyde oxidase (5). In each of these enzymes riboflavin is also present as the coenzyme FAD (flavin …

Food Availability And Selective Utilization By Juvenile Mallards (Anas Platyrhynchos Platyrhynchos L.) On The Bear River Migratory Bird Refuge, Utah, Nicholas J. Chura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This investigation was devoted to a study of food availability and the selective utilization by juvenile mallards (Anas platyrhynchos platyrhynchos L.) from hatching through the flight stage. Such information furnishes basic knowledge which may be used for determining the effects of chemical poisons on these organisms, how breeding ground habitats could be manipulated for their most efficient use by duckling species, what nutrients occur in natural duckling foods, and the digestibility of these items. The Bear River Migratory Bird Refuge, Utah, was used as the study area during the waterfowl breeding seasons of 1959, 1960, and 1961. Mallard ducklings …

A Study Of A Bacterial Cause Of The Late Gas Defect In Cheddar Cheese, Rulon A. Chappell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

More of the manufacturing milk purchased from Utah's dairy farms is used for the production of cheese than for any other product. Approximately eleven and one-half million pounds of cheese were produced in Utah in 1959, of which more than half was cheddar. Many problems are encountered in the production of A-grade cheddar cheese. One of the most important causes of the reduction in grade is the late gas defect which accounts for about 50 percent of the cheese grading below A-grade. To increase the percentage of A-grade cheddar cheese in Utah, the late gas problem should be solved. The …

The Effect Of Feeding Fluoride On Some Enzymes Of Bovine Tissues, Prasertsri Sitachitt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluorides are usually found in nature as constituents of soils, water, and the tissues of animals. Fluorite or fluorspar (CaF₂), cryolite (Na₃AlF₆), apatite (3 Ca₃ (PO₄)₂ CaF₂) and sedimentary phosphate rocks are among the principle minerals containing fluorides found in nature. Traces of fluorides also occur in domestic water supplies in nature and also by induction in vegetation and animal feeds. From 0.5 ppm to 1.5 ppm of fluorides in drinking water is the range found to be beneficial in reducing the incidence of tooth decay in man. …

A Comparison Of Cock Pheasant Harvests Among Areas Having Different Hunting Pressures, Cache County, Utah, James C. Bartonek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parsons (1953) found Utah's posted hunting unit system regulated hunting pressures over much of the state's pheasant range. He found inequalities of hunting pressure among the posted hunting units because of their individualistic methods used to determine the number of hunting permits to be sold. Utah State Department of Fish and Game personnel recommend the number of permits to be sold by the hunting unit; but often, the hunting unit officers use the desired level of hunting pressure, size of cock harvest, and revenue from permit sales as decisive factors. By regulating hunting pressure on their own lands the posted …

Influence Of Age On Milk Production Of Holstein Cows In Utah, Marvin R. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of dairy cows is influenced by many factors, among which are: genetics, nutrition, management, disease and age. Most of these factors can be modified to maintain a high level of production. Age, however, is beyond the influence of mankind; therefore, it is important to understand the effect of age on milk and butter-fat production.

Cuterebra (Diptera: Cuterebridae) Of Utah And The Neighboring States, Charles L. Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cuterebra are robust flies, which in flight resemble large black bees. Little is known about the bionomics of most of the species included in this genus. Nearly all members of this group parasitize rodents and lagomorphs. Some species have a wide host range, others seem to be specific or semi-specific to a single host. Accidental parasitism of animals other than specific host animals does occur. In such cases the larvae or the host usually die before the larvae can mature. There is a wide variation in the effect of of the parasite on its host. If the parasite is found …

Alfalfa Seed Production Studies, M. W. Pedersen, William P. Nye

All PIRU Publications

From a practical standpoint, the culture to use is the one that gives the greatest net return. The study indicates that planting alfalfa for seed production in 24-inch rows at a rate of 1.5 pounds of seed per acre and thinning in the fall of the year after planting is best. For example, a field planted in the spring of 1963 should be thinned in the fall of 1964. Cutting out approximately every other foot within the row seems advisable. While there appears to be considerable latitude in the extent of thinning, weed problems are encountered if the stand is …
