Scorpions Of Utah, John D. Johnson

Theses and Dissertations

Scorpions from Utah were collected and studied to determine species present, geographic distribution, seasonal occurrence, sex ratio, and some morphological variations associated with distribution. Nine species were identified--Anuroctonus phaeodactylus, Centruroides sculpturatus, Hadrurus arizonensis, H. spadix, Vejovis becki, V. boreus, V. confusus, V. wupatkiensis, and an undescribed species of Vejovis, subgenus Paruroctonus. Five species--C. sculpturatus, H. arizonensis, V. becki, V. confusus, and V. wupatkiensis--are reported from Utah for the first time. Most specimens were collected from May through October, with greatest numbers taken in May, June, and July. Sex ratios differed with the species. Two species--A. phaeodactylus and V. boreus--showed statistically …

The Ecology And Life History Of Sceloporus Occidentalis Longipes Baird On Rainier Mesa At Nevada Test Site, James Mark Hopkin

Theses and Dissertations

The study was undertaken to learn the life history of Sceloporus occidentalis longipes and its environmental adaptations on a high plateau (Rainier Mesa) with an elevation of 2,286 meters, at the Atomic Energy Commission's Nevada Test Site in Nye County, Nevada. The lizards emerge from hibernation in April with the males preceeding the females by a period of one to two weeks or more. Mating occurs in late April, May, and perhaps early June. Eggs are laid between 10 June and 15 July. Clutches of 9 to 15 eggs are laid with the younger females usually laying 9 eggs. No …

Overwintering Sites And Winter Mortality Rates Of Certain Predaceous Mites In Central Utah Orchards (Phytoseiidae: Typhlodromus), John Wayne Leetham

Theses and Dissertations

The overwintering habitats and winter mortality rates of predaceous mites (Phytoseiidae: Typhlodromus) were investigated during three successive winters, 1965-66, 1966-67, and 1967-68. Three species were predominant in derelict apple orchards, Typhlodromus mcgregori Chant on twigs and spurs and rough bark of scaffold limbs and trunk, Typhlodromus occidentalis Nesbitt on rough bark of scaffold limbs and trunk, and Amblyseius cucumeris Oudemans in ground cover. Other species (Typhlodromus columbiensis Chant, Typhlodromus caudiglans Schuster, Amblyseius fallacis (Garman), Amblyseius ovatus (Garman), Amblyseius floridanus (Muma), and Amblyseius rosellus Chant) were collected only incidentally. Substantial numbers of T. mcgregori and T. occidentalis were found to fall …

Nesting Ecology Of The Ferruginous Hawk (Buteo Regalis) In West-Central Utah, John Bradford Weston

Theses and Dissertations

During the spring seasons of 1967 and 1968 ecological studies were made of nesting Ferruginou.s Hawks (Buteo regalis) in a 325 square mile area in west-central Utah. In the springs of 1967 and 1968 a systematic search was conducted throughout the study area for Ferruginous Hawk nests. When active nests were located they were kept under observation throughout the study. The density of nesting pairs in 1967 and 1968 ranged from 7 to 15.4 square miles per pair. An annual seasonal displacement was exhibited, with Ferruginous Hawks being present in the study area only during the nesting season, which lasted …

Inhibition Of Planarian Regeneration, Douglas Pierre Bingham

Theses and Dissertations

This thesis describes my study of inhibition of brain regeneration in planaria. The flatworm (Dugesia tigrina) possesses a remarkable ability to regenerate lost parts, including the head. The primary objective of my study was to determine the extent to which an inhibiting substance, located in the head, would prevent regeneration of the brain. A secondary objective was to study whether DMSO (Dimethyl Sulfoxide) would facilitate the action of the inhibitor.

A Study Of The Channel Catfish, Ictalurus Punctatus (Rafinesque), In Mud Lake, Utah, Horst Friedrich Siewert

Theses and Dissertations

From June to November 1967, a study on channel catfish, lctalurus punctatus (Rafinesque), in Mud Lake, Utah Co., Utah was undertaken. The objectives were (I) to estimate if channel catfish are increasing or decreasing in Mud Lake, (2) to estimate the mean size of adult channel catfish in Mud lake, (3) to determine which environmental factors effect the catch of channel catfish, and (4) to determine if the channel catfish in Mud lake are residents year round. A total of 310 mature channel catfish and 920 carp were collected with four hoop nets. Two fingerling were captured by seining. Ratios …

The Effect Of Follicle-Stimulating Hormone And Testosterone Propionate On The Reproduction Of The Bull Snakes, Pituophis Melanoleucus Catenifer And Pituophis Melanoleucus Affinis; Accompanied With Analysis Of Changes In Blood Protein Constituents Following Stimulation, Jack Bradford

All Master's Theses

The bull snake, Pituophis melanoleucus, was chosen for this experimentation for several reasons; (1) it is relatively abundant in Central Washington (2) it is a large snake, well able to withstand the effects of the frequent blood samplings which were necessary in this experimentation ... (3) the bull snake is an oviparous snake and ova development is rapid and after dissection, obvious.

Nesting Ecology Of The Great Horned Owl Bubo Virginianus In Central Western Utah, Dwight Glenn Smith

Theses and Dissertations

Information was collected on the nesting ecology of the Great Horned Owl, with particular emphasis placed on aspects of its population and distribution, territoriality and predation. The study was conducted for the two years, 1967 and 1968 in the Thorpe and Topliff hills of central western Utah. Nesting densities on the study area were .36 pairs per square mile in 1967 and .40 pairs per square mile in 1968. Nests averaged one mile apart and were distributed in the periphery of the hills, overlooking the desert valleys. Favorite nest sites were cliff niches, but abandoned quarries and junipers were also …

The Cat Flea, Ctenocephalides Felis, As A Potential Vector Of Trypanosoma Lewisi, Robert Patrick Belihar

Theses and Dissertations

The first hemoflagellate was discovered by Valentine in 1841; two years later Gruby established the genus Trypanosoma for a flagel-late in the blood of frogs, and in 1879 Lewis in India described Try-panosoma lewisi Kent of the rat (Belding, 1965:141).

Fall And Winter Population Study Of The Macro-Invertebrate Fauna Of Lincoln Beach, Utah Lake, With Notes On Invertebrates In Fish Stomachs., Ralph Buckly Brown

Theses and Dissertations

Due to the inconveniences associated with under ice population studies, most aquatic population studies are made during the spring, summer, and fall seasons. Like most lakes little is known about the fall and winter popu-lations of the Utah Lake invertebrates. The purpose of this study is to classify, determine quantitative fall and winter population fluctuations, and obtain life history and ecological information of the macro-invertebrates at . Lincoln Beach, Utah Lake. This lake is the largest, natural occurring body of fresh water in the state and has a high potential for the production of gamefish and water-fowl. As Smart (1960) …

Some Phage Associated Properties In Salmonella Potsdam, Thomas B. Seifert

Loma Linda University Electronic Theses, Dissertations & Projects

The non-lysogenic strain and several lysogenic strains of S. potsdam were tested biochemically and antigenically to detect any possible phage related property.

Fermentation reactions and citrate utilization tests were identical for all strains.

Tubes agglutination tests showed the non-lysogenic and lysogenized strains of SP2-S to be similar, and different from the naturally lysogenic strains SP3, SP4, SP9, and SP10. Absorption tests confirmed the SP2-s strains, either non-lysogenic or lysogenized, to possess an additional antigen SP3 and SP4 did not possess. SP9 and SP10 may contain small amounts of this antigen. From variation may explain the antigenic difference between these strains. …

The Transfer Of Hydrogen In The Reduction Of Progesterone, William H. Kersey

Loma Linda University Electronic Theses, Dissertations & Projects

Experimental female rats were given daily injections of synthetic estrogens for six months. The effect on rat ovarian 20α-OH-SDH was not definitive. Diethylstilbestrol and 17α-ethynylestradiol caused a significant drop in activity as compared with controls while mestranol caused a slight increase in activity. A synthetic progestin, medroxyprogesterone, had no apparent effect on the activity of the enzyme.

Rat ovarian 20α-OH-SDH was purified fivefold by ammonium sulfate fractionation and chromatography on DEAE-cellulose.

The homogeneity of the enzyme was checked by means of disc gel electrophoresis. At pH 8.2 no significant contamination appeared in the electrophoretic pattern, but at pH 9.0 five …

Measuring Milk Flow Of Dairy Cows, G. H. Schmidt, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Milk flow measurements on 124 cows were analyzed to determine how they are affected by vacuum level, pulsation rate, pulsation ratio of the milking machine, and the breed, age, stage of lactation, and milk yield of the cow. Average rate of flow prior to machine stripping, yield during the first minute, and yield during the first 2 rain of milking were highly correlated with maximum rate of milk flow. These measurements were significantly increased by days in milk, vacuum level, pulsation rate, pulsation ratio, and total yield. Age at calving had a slight effect on yield during the first minute …

Relative Selection Efficiency In Retrospect Of Selected Young Sires, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The indexes used in retrospect in estimating one-half genetic value (daughter superiority) of progeny of 541 Holstein matings contracted by Eastern Artificial Insemination Cooperative were determined. A set of information on relatives to be complete would include records of paternal sisters, the dam, paternal sisters of the dam, maternal sisters, maternal grandam, and maternal sisters of the dam. The average index of daughter superiority for the 541 progeny was between 406 and 455 kg of milk, depending on which combination of relatives was used. Paternal sisters accounted for 45 to 50% of the total daughter superiority. Records of maternal relatives, …

An Investigation Of A Thyroidal Control Of Water Balance In The Leopard Frog, Rana Pipiens, Scott Mcclung Martin

Theses and Dissertations

A possible thyroidal control of water balance in the leopard frog, Rana pipiens, was investigated by (1) chemically thyroidectomizing intact animals by chronic injections of the goitrogen, 6-n-propyl-2-thiouracil (PTU ), or making animals hyperthyroid with thyroxine injections, and (2) dehydration of the frogs in a flow of air to enhance the rate of water loss through the skin, followed by rehydration in tap water until the animals regained their former weight. Radioiodine was employed in limited studies on the frog thyroid gland to ascertain the effects on thyroidal function caused by PTU. The frogs were dehydrated in desiccators in which …
