A Description Of Anglers And Angling Use In Two Areas Of The Uinta Mountains, John F. Hoagland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The High Uinta Primitive Area, Utah's most popular high mountain recreation area, has a reputation as an excellent trout and grayling fishery. Proposed for inclusion in the National Wilderness Preservation System, the area faces several management dilemmas. The primary problem being that managers must protect the resource from the effects of heavy recreational use without destroying the primitive and aesthetic dimensions of wilderness environment. It appears that much impact on the more accessible lakes is due to fishing use. The objectives of the study were: (1) to determine the proportions of angling to non-angling groups; (2) to describe certain characteristics …

Short-Term Memory For Temporal And Spatial Order Information, Alice F. Healy

Student Theses and Dissertations

The present investigation includes theoretical and experimental comparisons of short-term memory for temporal and spatial order information. Two questions are of central interest: whether short-term memory for letter sequences is limited to a verbal-acoustic coding process and whether the loss of information from short-term memory results from interference or from a mere decay with time. The basic experimental paradigm employed in the present study was the Brown-Peterson design. The items to be recalled were sequences of four consonants presented visually in varying temporal and spatial arrangements. On each trial the to-be-remembered sequence of consonants was followed by an intervening task …

Effects Of Ventromedial Hypothalamic Lesions On Food-Reinforced Fixed Ratio Responding, Ronald Paul Larkin

Student Theses and Dissertations

Previous research has shown that rats with experimental lesions in the ventromedial area of the hypothalamus become obese due to hyperphagia. This striking effect on ad libitum food intake is sometimes accompanied by an increase and sometimes by a decrease in other measures of propensity to eat such as food-rewarded lever pressing. The current experiments attempt to discover the conditions under which these opposite effects on "food-motivated" behavior occur. Rats with ventromedial lesions made with steel electrodes showed a decrease relative to controls in lever pressing on a fixed ratio schedule. This effect was also seen in rats which had …

The Effects Of Acute Stress On Adrenal Ascorbic Acid Levels, Robert Joseph Collier

Masters Theses

The diurnal rhythm of adrenal ascorbic acid (DAR) displays an inverse relationship to the diurnal rhythm of circulating levels of plasma corticosteroids. Alloxan monohydrate, 175 mg/kg body weight was given subcutaneously to albino rats to determine the effect of the diabetic state on the DAR. A total of 200 female albino rats were divided into two study groups. Study Group I was composed of 150 animals divided into populations of 15, each including 3 controls. Study Group II was composed of populations of 5, each group containing all controls or all alloxinated rats. The populations of 15 were sacrificed at …

Critical Flicker Frequency In A Harp Seal, Pagophilus Groenlandicus (Erxleben, 1777), Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) in a free-swimming harp seal (Pagophilus groenlandicus) was investigated using behavioral techniques. The resulting CFF versus intensity contour indicates a definite rod-cone break, confirming a duplex photoreceptor population whose presence had not been observed in previous morphological reports.

Recreation Research—So What?, Perry J. Brown, Allen Dyer, Ross S. Whaley

Forest Management Faculty Publications

The authors contend that most recreation research cannot stand the question, "So what?” From that point the article proceeds to a prescription for a meaningful approach to recreation research, which links recreation research to planning within a systems context. Researchable questions are posed dealing with preferences and behavior, resource capabilities and environmental impacts, and the nature and dynamics of institutions for the original state, process, and desired state segments of a planning system.

Avoidance Learning In Drosophila Melanogaster, William Lucas

University of the Pacific Theses and Dissertations

The importance of showing that Drosophila are capable of learning an instrumental response would, with the information already known from genetic studies, enable researchers to possibly isolate the genetic basis of a simple learning process and thus gain greater insight into this phenomenon. If a reliable technique can be found for earning in Drosophila, a new field of research would be opened which could greatly add to our knowledge of the evolution of behavior.

The following two studies attempted to demonstrate that Drosophila can learn and also investigated which system, vision or olfaction, serves best in this capacity.

An Electromyographic Study Of The Effects Of Lateral Asymmetry On The Upper Leg Muscles Used In Normal Walking On A Treadmill, S. Marie Landmesser

Masters Theses

The purpose of the study was to determine through electromyography whether a non-pathological fault, such as lateral asymmetry at the pelvic level, would hinder, in significant manner, efficient functioning of the body.

A review of the literature revealed that although previous experiments had been conducted to determine the effects certain postural deviations had on the normal, efficient functioning of the body and that previous experiments had been conducted to determine which muscles performed which task as related to walking, none dealt with the specific effects of lateral deviations at the pelvic level on the upper leg muscles used in walking. …

The Development Of Social Interaction, Play, And Metacommunication In Mammals: An Ethological Perspective, Marc Bekoff

Ethology Collection

Analysis of the dynamics of the ontogeny of social interaction is of critical importance in order that behavioral development may be comprehended in its own right, and the relationship between infant and adult behavior understood. In this review, general concepts of behavioral development in mammals are discussed and analyzed, and the many variables that are involved are considered. When it is impossible to control or observe the social interaction of the developing organism in its natural environment, captive subjects should be used. There is increasing evidence that results obtained with the latter are related to social organization observed in the …

The Elusive Tree Quails Of Mexico, Paul A. Johnsgard

Paul Johnsgard Collection

The three species of tree quails or wood-partridges, genus Dendrortyx, of Mexico and Central America are all surprisingly large — weighing up to one pound in the case of the largest species — and have relatively long tails that result in an overall body length of from 9 to 16 inches. Their beaks are large and heavy, and are related to their abilities to tear apart and consume fruits, flower buds, and similar materials.

Three species of tree quails have been described, all of which occur in moist montane forests, especially the mist-shrouded cloud forests that occur at elevations …

Effects Of Dietary Factors And Morphine Administration On Voluntary Alcohol Consumption And Dopamine Metabolism In Rats, Claudia Smithson

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of diet and dietary additives on voluntary alcohol consumption in male Sprague-Dawley rats was studied. Alcohol intake measured weekly and reported as ml of a 10% solution ingested per 100 grams body weight. A four week pre-experimental period was designed to determine individual tendencies to drink and thus to eliminate the high and low drinkers from the study. No difference was found in alcohol intake with either starch or sugar as the carbohydrate source; however, there was a greater weight gain ( p < .025) in those animals consuming sugar-based diets. Rats on poor-quality diets containing minimal amounts of vitamins and minerals continued to gradually increase alcohol consumption during the study. This diet, supplemented with coffee, caused the greatest significant increase in alcohol intake and the lowest weight gains. Addition of coffee to the diets significantly increased alcohol consumption (p< .005) but decreased growth rate (p < .0005) . However, when the poor quality diets were supplemented with vitamins and minerals, alcohol consumption was reduced by about 50% (p < .005) and weight gain was significantly increased (p < .0005).

The daily intraperitoneal administration of morphine sulfate significantly decreased alcohol intake (p < .02) and the per cent of total fluid consumed as alcohol (p < .02) but did not effect water consumption.

An attempt was …
