The Effects Of Altered Prey Availability And Shrub Architecture On Spider Community Parameters: A Field Experiment In A Shrub-Steppe Ecosystem, Kathryn Wing

Biology

The effects of altered prey availability and shrub architecture on spider community parameters were studied in a field experiment in northeastern Utah. Treatments of 2 states of foliage density--"normal" and tied (= high density)--and 2 states of insect attractant-- control and baited--were applied to big sage shrubs (Artemisia tridentata) using a factorial experimental design. Temperature and humidity were not significantly different between the 2 types of shrub architecture. The species array and abundance of shrub insects were not significantly altered by the foliage density treatment. Shrubs with insect attractant had significantly larger insects (as measured by body length) …

Isozyme Variation Among Geographic Populations Of The Alfalfa Weevil, Hypera Postica (Gyllenhal), In Utah, John M. Stutz

Biology

The objectives of this study were to estimate the amount of genetic variation present among populations of the alfalfa weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae), and to determine the amount of divergence between these populations. The enzyme products of 25 loci (acid phosphatase, alcohol dehydrogenase-2, alcohol dehydrogenase-3, amylase-1, amylase-2, aldehyde oxidase, esterase-1, esterase-2, esterase-3, fumarase, glucose-6-phosphate dehydrogenase, glutamate dehydrogenase, glutamate-oxaloacetate-transaminase, alpha-glycerophosphate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase, malate dehydrogenase-1, malate dehydrogenase-2, malate dehydrogenase-3, malate dehydrogenase-4, malic enzyme, superoxide dismutase, tyrosinase-1, tyrosinase-2, tyrosinase-3, xanthine dehydrogenase) were examined using polyacrylamide gel electrophoresis for four Utah alfalfa weevil populations; two from the north (Logan and Payson) …

An Electron Microscopic Study Of The Gill Chamber Of A Dragonfly Nymph (Odonata:Anisoptera), Patricia Bohm Trostle

Biology

The respiratory chamber of the dragonfly nymph, Aeshna multicolor, was studied by means of scanning and transmission electron microscopy. Transmission electron micrographs enable several cellular types, includig two epithelial types, to be distinguished within the individual gill fold. Epithelial cells located basally on the gill fold show features of an osmoregulatory tissue. Cuticle limiting these cells is thinner than-that of typical epithelium, the plasmalemmae are infolded enclosing numerous mitochondria, and a system of extracellular channels is located basally with mitochondria and glycogen seen in the basal cellular outfoldings. Tracheoles are rare. Epithelial cells more distally placed are typical of …

The Effect Of Reproductive Phase And Hormone Treatment On Receptor Sites For Reproductive Hormones In The Ewe, Jane R. Mole

Biology

Groups of at least six ewes each during the estrous and anestrous seasons were estrus synchronized using progesterone implants and superovulated using follicle stimulating hormone (FSH) or pregnant mare serum gonadotropin (PMSG), or left as nonsuperovulated controls. Ewes were sacrificed 30 h after removal of implants. The hypothalamus, adenohypophysis and ovaries were removed and frozen in liquid nitrogen. Frozen sections of all tissues were incubated with radiolabeled hormones to determine location and quantity of receptor sites. Slides were dipped in autoradiography emulsion and allowed to self expose 10 days before they were developed and stained. Slides were then examined using …

A Lactic Culture Stimulant Blend From Kluyveromyces Fragilis And Whey, Steven L. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A buffered growth medium was developed that sustained a significantly greater concentration of various strains of Streptococcus lactis and Streptococcus cremoris than did milk. The active buffering ingredients of this medium were magnesium hydroxide, ammonium and sodium salts of phosphate and citrate. This medium was entitled Lactic Culture Buffered Growth medium (LABGRO) and possessed about 8 times the buffering strength between pH 6.6 and 5.1.

Significant differences in growth and acid production rates were noted among Prt+ and Prt- lactic strains evaluated. Also noted were significant differences in cellular acid production rates. The two Prt- strains having the slowest growth …

Plant Gas Exchange Of Two Bunchgrasses In Relation To Herbivory Tolerance, Robert S. Nowak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The occurrence of compensatory photosynthesis was examined in the field during the spring for all foliage elements on two Agropyron bunchgrass species that differ in their evolutionary history of grazing pressure. Compensatory photosynthesis did occur in many individual foliage elements during at least part of their ontogeny. For both species, compensatory photosynthesis was related primarily to delayed leaf senescence and increased soluble protein concentrations, but not to an improvement in the water status of clipped plants. Photosynthetic water use efficiency and photosynthetic rates per unit soluble protein of foliage on partially defoliated plants were not increased following the clipping treatments. …

A Look At Some Grandfather Intergenerational Relationships As Perceived By Their Adult Children, Leonard E. Stout

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate the quality of grandfather's relationships with his adult child and their oldest child. A questionnaire was used to obtain demographic data, determine some personality and interaction patterns that can be observed as the male adult develops in the parent and grandparent roles, and examine how specific variables affect grandfather relationships and behavior. Data were gathered from 165 Utah State University students and their spouses, of which over 75% belong to the Church of Jesus Christ of Latter-day Saints.

The results support good intergenerational relationships. Proximity of grandfather and extended family members was …

Initial Assessment Of The Introduction Of Spottail Shiner (Notropis Hudsonius) And Delta Smelt (Hypomesus Transpacificus) Into Willard Bay Reservoir, Utah., Thomas E. Sommerfeldt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spottail shiner (Notropis hudsonius) and delta smelt (Hypomesus transpacificus) were introduced into Willard Reservoir to improve the forage base for walleye (Stizostedion vitreum vitreum) and black crappie (Pomoxis nigromaculatus). Spottail shiners were stocked in early spring in 1981, 1982, and 1983. Hauling mortality was generally great and an estimated 34,500 live fish were stocked in the 3-year period. Spottail shiner reproduction occurred each year of stocking. Delta smelt were introduced in 1982 with the stocking of 15,000 adult spawning fish. Stocking survival was estimated at 99%. Freshly spawned eggs were also obtained …

Effects Of Clearcutting On Forage Production, Quality And Decomposition In The Caatinga Woodland Of Northeast Brazil: Implications To Goat And Sheep Nutrition, Robert D. Kirmse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Clearing of trees from the so-called caatinga woodland that characterizes the vegetation of the semi-arid region of northeast Brazil offers possibilities for increasing forage production. This research analyzed the first-year effects of clearing caatinga on dry season forage for goats and sheep. In addition, factors affecting litter decomposition on cleared and uncleared caatinga were assessed to evaluate the viability of deferring grazing of forages during the wet season for use later in the dry season.

Removing the trees resulted in a sixfold increase in production of herbaceous vegetation, however, 88 percent of the increased yield on the cleared areas was …

Petrology Of The Middle Jurassic Twin Creek Limestone, Lincoln And Sublette Counties, Southwestern Wyoming, David R. Raubvogel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Twin Creek Limestone of Middle Jurassic age was studied in the Tunp, Salt River, and Wyoming Ranges in southwestern Wyoming. Modern carbonate environments and their ancient analogs were compared with information obtained from field study and petrographic analysis of samples of the Twin Creek Limestone in order to delineate environments of deposition, paleogeography, and diagenetic history.

Six major lithofacies were recognized: (1) carbonate mudstone; (2) carbonate mudstone breccia; (3) fossiliferous wackestone; (4) packstone-grainstone; (5) terrigenous mudstone; and (6) sandstone. These lithofacies were deposited in a variety of environments, including outer shelf platforms (carbonate mudstone and fossiliferous wackestone), oolitic sand …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A computer model for use in predicting the impact of various improvement options on command area expansion of a deep tubewell irrigation system has been developed. A field study was conducted on 11 selected deep tubewells located at two sites, namely Dhamrai and Thakurgaon, in Bangladesh to collect necessary physical data to provide irrigation engineering insight and a basis for testing and application of the model. The results of the investigation revealed that the actual discharge of most of the deep tubewells was lower than the design or rated capacity. The duration of pump operation in the majority of the …

The Effects Of A Commons Simulation And Fines On A Generalization Test, William Boyle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study investigated the effect of a commons simulation and fines on a generalization test that incorporated several features important in the real world. Two hundred and seventy-five volunteer college students in groups of seven participated in this study. Approximately one-half received exposure to the commons simulation and one-half did not. One-half of the groups in each treatment level received two posttests with a fine option available and the other one-half received two posttests without this option. The two posttests differed in that one was played with a large unknown referent group and the other was played with the …

Eeg And Evoked Potential Measured Of Age And Sex Differences In Central Nervous System Processing, Judith Ann La Marche

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Age and gender differences in CNS information processing were investigated with EEG measures of power spectral analysis and cortical coupling, and evoked potential measures of brainstem auditory evoked potentials (BAEPs), visual evoked potentials (VEPs), pattern reversal evoked potentials (PREPs), and P300 evoked potentials. Eighty normal volunteers comprised four subgroups of 20 subjects: young females and young males (25-35 years); old females and old males (55-70 years).

Trends were generally consistent across evoked potential measures: women and young people produced faster latency responses; females and oldsters produced larger amplitude responses. Old age was associated with reduced variability of electrophysiological responding across …

Adolescent Identity Status In Current Familial Relationships During Separation, Eugene E. Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

College students were assessed as to ego identity status and perceptions of their relationships with parents during their first year away from home. Each parent was also asked to rate the relationship. There was general agreement between parents and adolescents although the data indicate that mothers and adolescents share a more similar view of their relationship than did the fathers and adolescents.

The hypothesis that females would report more affection and communication with their parents than would males was partially supported. Daughters were more communicative with their mothers and were more affectionate toward both parents than were sons.

Several proposed …

An Economic Analysis Of Food Policy In The Ivory Coast, Yao Prao Felix

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ivory Coast covers an area of 124,000 square miles with reasonable rainfall for food crops production. But besides what has been called the economic "miracle," the country relies on increasing food imports (rice, wheat, meat, and milk products). At the same time, the country's earnings from the major export commodities are shrinking. So the primary objective was to identify the main causes and circumstances that have resulted in reductions in food production. The major hypothesis was that the present situation is simply the result of policies that have favored cash crops relative to good products. A formal treatment and an …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A feeding trial was conducted comparing four finishing diets, typically fed in this area, two hormone implants zeranol (Ralgro) and estradiol 17-beta (Compudose), and a feed additive. Thirty-two Hereford steers were fed in individual pens to maintain accurate intake records. The four diets compared were: 1) a whole corn diet with a small amount of corn silage as roughage; 2) a high energy ground barley diet using corn silage and chopped alfalfa as roughage; 3) a total diet consisting of rolled barley, beet pulp, and ground alfalfa hay; and 4) a high energy rolled barley diet using corn silage and …

The Cost Effective Acquisition And Dissemination Of Market Information: A Computerized Approach, Tammy Burton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Clearly, many of the developments in computerized market systems are regarded as revolutionary in an industry which has undergone diminutive changes in marketing its products and acquiring current market information. Cognizance of the agricultural market situation is pertinent for maximum production efficiency, bargaining strength, and financial success for producers.

Collectively, producers in Utah face the dilemma of receiving approximately ten percent less in cash receipts for their commodities than their counterparts in surrounding states. Market information that was attainable by producers was often obsolete, redundant, expensive, and irrelevant to the market situation in Utah.

The implementation of a Computerized Market …

Effects Of 3, 5, 6-Trichloro-2-Pyridinol On Thyroid Function, Charles Franklin Luke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

3,5,6-trichloro-2-pyridinol, when administered in the diet, increases the feed efficiency (the ratio of weight gain to feed consumed) in various species of domestic animals and also appears to be retained in the liver at low concentrations, possibly by binding to a specific macromolecule. Because of its structural similarities to the outer ring of the thyroid hormones, trichloropyridinol and three structural analogs (2,4,5-trichlorophenol, 4-bromo-2,5-dichlorophenol, or 4-iodo-2,5-dichlorophenol) were tested for ability to compete in vitro with 3,5,3'-triiodothyronine (T₃) for nuclear receptors specific for the thyroid hormones. All four of the halogenated compounds were found to be weakly competitive for the …

Vocal Behavior And Interactions Among Parents And Offspring In The American Dipper, Mary Kathleen Fite

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The American Dipper (Cinclus mexicanus), an inhabitant of rapidly flowing mountain streams, is an aquatic passerine whose vocalizations have previously been undescribed. This study examines the spectrographic characteristics and contexts of calls and song in a color-banded population of Dippers. Calls of adults are the Jih, Weep and Grawk calls; calls of nestlings and fledglings are the Chip and Beg calls. Adult Dippers have a limited number of call types which occupy a middle range of frequencies (3 to 6kHz) and have structural characteristics which enhance detection of vocal signals. Gradation is present between call types. Possible explanations …

Fear Of Crime Within The Boomtown Setting, Jerry Bartlett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this thesis is to explore the phenomenon of fear of crime in the context of two highly distinct small town environments: one characterized by extremely rapid population growth due to energy development, and the other characterized by relative stability and slow population expansion. Although in general prior fear of crime research has indicated relatively low levels of fear in rural small towns, the altered social environment of the rapid growth community may result in substantially heightened fear of crime. Using survey data collected from random samples of households in each of the study communities, the relationships between …

The Value Of Microcomputers In Agriculture, John P. Gibney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was two-fold. To examine the hardware and software purchased, training taken, and benefit recieved by farmers recently purchasing micro computers and to demonstrate a systematic approach of evaluating software. Over five hundred farmers that use microcomputers were surveyed on farm size and type, personal and computer system characteristics, and perceived benefit from the computer. Farmers that use computers were found to be younger, have higher incomes and benefit more from their computer systems with time than averages for all farmers. The use of printers and/or modems appeared to be justified for all levels of income. …
