The Effect Of Pregnancy And Lactation On The Iodine Compounds In The Tissues And Plasma Of The Rat, Harry Jay Lyons

Theses and Dissertations

An isotopic equilibrium method was employed, based on the chronic feeding of an 125I-labeled diet of known specific activity, to determine the distribution and quantitation of endogenously labeled iodine-containing compounds in the female rat at various periods during gestation and post-parturition. A decrease was associated with gestation in the total iodine, which was significant in all extrathyroidal tissues except the brain and muscle, and a fall in thyroxine concentration which was significant in all extrathyroidal tissues except the heart. The triiodothyronine level decreased from the control values in gestation but not as consistently. There was also a significant decrease in …

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 …

Tumbleweeds: Ecology And Abscission, Donald A. Becker

Theses and Dissertations

A study of tumbleweeds in North Dakota, conducted from June, 1964 to October, 1968, was concentrated on two common species: Psoralea arqophvlla Pursh (silver leaf psoralea) and Kochia scoparia (L.) Schrader (kochia). The objectives were to determine the internal or external factors regulating stem abscission, and to describe the niche of each species through the ecological life history approach. Anatomical and histochemical studies were conducted on the basal portions of stems at various stages of plant maturity. Ecological life history aspects of silver leaf psoralea were studied both in the field and under controlled environmental conditions, while those of kochia …

The Nonpartisan League : A Quest Of Community, Leonard Wentz

Theses and Dissertations

The purpose of this thesis is the examination and appraisal of the rise and decline of the Nonpartisan League as a mass movement in North Dakota. Previous interpretations have been mostly economic in nature. This study interprets the League members I situation from the socio-psychological view. This thesis will attempt to show the editorial directions of leading newspapers with regard to the agrarian situation from 1916 to 1920.

The procedure involved a study of the sociological conditions of the North Dakota farmers before they accepted the Nonpartisan League ideology. The Nonpartisan Leader's editorial policy was viewed to show its interpretation …

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.
