All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rainbow trout lactate dehydrogenase (LDH) B²' B²' , B²' B²" and B²" B²" phenotypes were tested under a variety of conditions for swimming endurance, oxygen consumption rates, and blood pH, pO₂, and lactate. The B²" B²" phenotype exhibited a lower swimming endurance, under a limited oxygen supply, than the B²' B²' and B²' B²" phenotypes. Blood pH at fatigue did not differ among the LOH phenotypes that swam under low oxygen conditions (2 mg/1). …

A Discriminant Function Model Of Gray-Headed Junco Habitat, Andrew R. Grainger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents a description of gray-headed junco habitat in the form of a model based on discriminant function analysis. Junco nests were found by searching randomly located grids on a 7.8 km² study area in central Utah. Vegetation data was gathered on 500 m² circular plots surrounding nests and contrasted with similar data from searched grids where nests were not found. The model explains 28 percent of the between-groups variance and correctly classifies 68 percent of the plots.

Plant cover types are good predictors of areas where gray-headed juncos nest, while plant community type descriptions do not …

Park Visitor Responses To Natural Hazards, Lee H. Rentz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural hazards have been an increasing problem in wildland recreation areas. This study attempted to identify factors affecting park visitor perception of and preparedness for hazards.

A model was formulated incorporating three major independent variables which might affect park visitor responses to hazards. These were: (1) previous experience, (2) information about hazards provided by the park administration (such as warnings located on signs or in brochures), and (3) visitor perception of whether responsibility for hazards rests with the individual or with an outside authority such as government or God. Trip length and knowledge of hazards were also thought to be …

Physiological Response To Hooking Stress In Largemouth Bass (Micropterus Salmoides), A. Wayne Gustaveson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent concern about large initial and delayed mortalities resulting from tournament angling for largemouth bass has indicated that it would be desirable to further evaluate the fate of fish that are released after being captured by angling. This study was designed to evaluate sublethal physiological disruptions caused by hooking stress after largemouth bass were played under standardized conditions (0-5 minutes) and to estimate the time needed for recovery of the homeostatic mechanisms (to 72 hours). Blood lactate was used as a measure of metabolic fatigue; plasma osmolality and chloride measurements were used to evaluate osmoregulatory disturbances and gill ion-exchange; and …

Leaf Development Of Rumex Patientia L. Exposed To Uv Irradiation (280-320 Nm), Judith G. Dickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two factors which affect leaf ontogeny and ultimate leaf size: (1) the rate and duration of cell expansion, and (2) the rate and duration of cell division, were examined for their role in the slowed early growth rate and smaller ultimate leaf size when plants are exposed to ultraviolet-B (UV-B) radiation. Rumex patientia L. was grown in controlled environment chambers under enhanced UV-B radiation (equivalent to daily solar UV-B irradiation at 40°N latitude in mid-May with an atmospheric ozone concentration of 0.20 atm-cm) and control treatments. The pattern of growth as expressed in changes of mean cell size of two …

Population Dynamics And Net Production Of Brown Trout (Salmo Trutta) In Two Areas Of A High Gradient Mountain Stream, Jeffrey C. Gosse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Estimates of the brown trout (Salmo trutta) population were made in two areas of the Blacksmith Fork River, Cache County, Utah, from June 1972 to June 1973. Additional data were obtained on movement, growth, mortality, biomass, production, and yield.

Population density was highly variable in the area where habitat alterations had occurred, but was relatively uniform where the habitat was undisturbed. The brown trout exhibited little movement except during spawning season. Instantaneous growth and mortality rates are provided for each age group.

Mean annual biomass in the two areas was 12.0 and 10.2 grams per square meter and …

Money Saving By Children: The Effects Of Interest And Instructions, James Thomas Northrop

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In two experiments, groups of children received interest money contingent upon their savings; yoked control subjects received identical interest irrespective of their savings. In the first experiment, interest was paid every 3 days by parents for the average savings of the period. In Experiment II, interest was paid on a daily basis and control subjects received instructions concerning the lack of a relationship between interest and their savings.

In both experiments savings and magnitude of expenditures increased systematically across the research phases for contingent and non-contingent interest subjects alike. Neither interest nor subject wealth was found to relate to subject …

The Effect Of Inescapable Shock On Competitive Dominance In Rats, Pamela A. Cheney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experimental examination of the generality of learned helplessness has previously been confined to treatment and tests employing aversive motivators, such as electric shock. In the present study, rats were used to evaluate the effect of inescapable shock on their performance in a water test of competitive dominance which employs no aversive motivator. The subjects were paired and pre-tested for competitive dominance. In the experimental groups one member of each pair was treated with inescapable shock and the pairs were then post-tested for competitive dominance either 48, 72, or 168 hours after treatment. The control subjects were pre- and post-tested with …

Variables Associated With Fluctuations In Response Time On The Rorschach Test, Dean L. Gregg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A sample of 61 subjects from an introductory psychology class was administered a battery of psychological tests, among them the Rorschach and the MMPI.

The purpose was to determine the behavioral correlates, if any, of the two Rorschach variables, Mean Reaction Time, and Fluctuation in Time of First Response. This was accomplished by using multivariate statistical techniques, i.e. a factor analysis followed by a stepwise multiple regression.

The results were ambiguous. While not statistically significant, they suggest that the MMPI variables of Social Introversion and Psychopathic Deviant are more closely related to the two dependent variables than previous literature would …

Bait Shyness And Neophobia In Several Species Of Osteichthyes: An Extension Of Taste Aversion Studies To The Superclass Pices, Brent W. Roberts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three experiments were conducted with five species of tropical fish to investigate the phenomena of taste aversion and food neophobia. In addition, an experiment determined specifically if position in the tank could acquire conditioned aversive properties.

In Experiment 1 , four habituated fish were fed novel meat-flavored pellets on the treatment day. Six were made ill within 30, 60, or 90 minutes (2 subjects each) by intragastric administration of syrup or Epicac. The following day all were fed familiar commercial pellets. On the second day after treatment, all were offered the meat-flavored pellets. Results showed longer latencies, more tasting, and …

The Temporal Distribution Of Short-Duration Keypecks In Variable-Interval Schedules Of Reinforcement, Joseph G. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An experiment was conducted in order to determine the duration of pigeons' keypecks during three separate variable-interval schedules of reinforcement. Pigeons were exposed to variable interval (VI) 30 sec, VI 60 sec and VI 120 sec schedules of reinforcement for twenty sessions each. Response durations were analyzed in terms of VI schedule, location in time during the inter-reinforcement interval and any pattern of short and long duration pecks. Mean duration of response was reliably different for three out of four birds for VI 30 sec and VI 120 sec schedules of reinforcement. The VI 30 sec schedules produced longer durations. …

Potential For Cattle Grazing On Sheep Range In Southwest Utah, Jose Salvador Gutierrez-Garza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was conducted on pastures grazed by sheep in late winter at the Desert Experimental Range in southwest Utah. Estimates of plant cover and herbage production were obtained in 1977 and used to examine long-term trends in the vegetation.

The nutritional value of the six most important species of the area was assessed by chemical analysis. In addition, a management strategy was developed for obtaining some utilization of the range during the spring and summer months without affecting the traditional winter use by sheep.

Long-term records (since 1937) in cover suggest a modest increase in grasses and a decrease …

A History Of John W. Young's Utah Railroads, 1884-1894, Marlowe C. Adkins Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This is the story of three narrow gauge, short line railroads. Had fate been kinder, they might have become the hub of a major mountain west rail network. But this thesis will deal with facts, not possibilities, as it investigates the justification, construction, financing, and politics that surrounded these railroads and their location.

The locale was in and near Salt Lake City, Territory of Utah, during the decade between 1883-1894. Both location and time period have significance, for anti-Mormon feelings, within and without the the Territory, were very strong.

The visible cause of the anti-Mormon movement was polygamy.¹ For, …

Reduced Recruitment In Utah Mule Deer Relative To Winter Condition, Phillip J. Zwank

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reduced recruitment rates in Utah mule deer (Odocoilus hemionus) showed that significant losses in production were accruing during pregnancy, the neonatal period or during the first few months after birth. The primary objectives of the study were to determine the time, extent and possible causes of these losses.

Corpora luteal and fetal rates were estimated by examining the reproductive tracts of 125 carcasses collected on selected herd units in Utah and by observing the reproductive tracts of 136 female deer captured in Spanish Fork Canyon. A laparotomy was performed on each captured female to allow visual examination of the reproductive …

The Effect Of Architectural Variation In Habitat On A Spider Community: An Experimental Field Study -- With Special Reference To Resource Partitioning, James Vincent Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spider community acceptance of, and segregation by, architectural configuration was investigated for the spiders of Green Canyon in northern Utah. Modular habitat units consisting of 30.48 centimeter (1 foot) cubes of chicken wire supporting internal strands of macrame jute tied in different orthogonal configurations were used. Configurations including all three axes were tested at two strand densities.

The primary null hypothesis tested, that spider species use structures independent of architecture, was rejected in favor of the alternate hypothesis that spider species differentially use structures dependent upon architecture. Of the eight most abundant species, two showed preferences for horizontal substrata and …

The Combined Effects Of Air Temperature, Wind, And Radiation On The Resting Metabolism Of Avian Raptors, Steven R. Hayes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

American kestrels, Falco sparverius; red-tailed hawks, Buteo jamaicensis; and golden eagles, Aguila chrysaetos, were perched in a wind tunnel and subjected to various combinations of air temperature, wind, and radiation. Oxygen consumption was measured under the various combinations of environmental variables, and multiple regression equations were developed to predict resting metabolism as a function of body mass, air temperature, wind speed, and radiation load. Heat transfer analysis of the bird-thermal environment relationship was conducted to produce a biophysical model describing resting metabolism as a function of feather thermal conductance.

Because of differences in surface area to mass …

Analysis Of Ecosystem Models, Walter Dewey Valentine

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent attempts to apply frequency response analysis to compartmental models of ecosystems are flawed by the failure to define terms in an unambiguous and ecologically meaningful way, and by the failure to distinguish between information feedback and closed material loops. Analysis of the sensitivity of linear models to changes in the A matrix has shortcomings too: elements of the A matrix are often derived from more fundamental parameters and thus do not have a direct relationship to the parent model; only sensitivities to the fundamental parameters will be unconfounded and readily interpretable. A more serious problem with these techniques is …

Public Land Grazing: Going, Going, Gone?, E. Bruce Godfrey

Economic Research Institute Study Papers

America's publicly owned rangelands have been and will continue to be a major focal point of interest of members of the society. Recently, these lands have also become of interest to user groups which differ from the major traditional use of these lands--domestic livestock. The NRDC suit which spawned the environmental impact statements being written by BLM per- sonnel, the Resources Planning Act, and the Organic Act have focused attention on these lands to a greater degree that has not existed for some time. Much of the interest in these lands has questioned the role and impact of livestock grazing …
