A Study Of The Fluctuation Of Some Blood Chemical Constituents In Relation To The Reproductive Cycle Of The Mallard Duck, Edward H. Decker

Masters Theses

Introduction

The purpose of this study was to determine normal levels of several blood chemical constituents (the mineral sodium, potassium and calcium and the organic substances serum cholesterol and serum albumin) for the female mallard duck (Anas platyrhynchos) and to examine their relationships as a possible index to reproductive development.

Much research has been done on the chemical composition of the avian egg and only those constituents which are of concern in this study will be discussed in detail. According to Romanoff (1949), studies of the chicken egg have shown that only a few mineral elements are present in relative …

Cesium And Sodium Metabolism By The New Mexico Whiptail Lizard, Margaret Flory

Biology ETDs

The effect of temperature on electrolyte metabolism in the lizard Cnemidophorus perplexus was studied. The biological half-time and tissue distribution were the aspects of cesium and sodium metabolism noted. Increased temperature results in a higher metabolic rate. Measurements were made of the extent oxygen consumption increased with raised temperature in C. perplexus. Radioisotopes sodium-22 and cesium-137 were injected intraperitoneally into lizards kept at several environmental temperatures. Whole body radioactivity counts were taken twice daily on the live animals to determine the retention curves. At 50% retention and 80% retention lizards were sacrificed and tissue radioactivity counts taken to determine electrolyte …

Some Movements Of Black-Tailed Jackrabbits In Northern Utah, Donald H. Rusch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This work describes the extent and pattern of some black-tailed jackrabbit (Lepus californicus) movements and areas of activity in northern Utah and their relationship to sex and age, and season of the year.

Black-tailed jackrabbits are the most common lagomorphs in much of the western United States, particularly in that vegetational association described by McDougal (1908) as the sagebrush desert. Furthermore, Adams and Adams (1959) have suggested a correlation between sagebrush (Artemisia tridentata) incidence and jackrabbit density.

Farmers often regard this species as a liability because of its depredations on alfalfa (Medicago sativa), crested …

Some Morphological And Histological Effects Of The Poison Of Lophopodella Carteri (Hyatt) On Young Ambystoma Opacum (Gravenhorst) And Carassius Auratus (Linnaeus), Eric Justin Collins

Master's Theses

Larvae of the marbled salamander, Ambystoma onscum, and the goldfish, Carassius auratus, were subjected to poi­ soning by homogenates of Lonhopodella carteri. Stock homogenates were prepared by grinding specimens of frozen L. carteri in a rotary blender and adding distilled water to give a 20 percent concentration (wt./vol.); the stock was used to prepare working solutions.

Homogenates from bryozoans collected in 1964 were approximately twice as poisonous as those from the 1963 col­ lection. It ls possible that chemical changes during stor­ age and bacterial action prior to freezing caused deterioration of the poisonous principle in the material from 1963. …

The Origin Of The Grassland Amphibian, Reptilian, And Mammalian Faunas Of The San Juan-Chaco River Drainage, Arthur H. Harris

Biology ETDs

Grasslands of the San Juan-Chaco Drainage are separated from grasslands of other New Mexican drainages by plant associations characteristic of higher altitudes. Connection with other grasslands in the Colorado Drainage is restricted to a narrow corridor in the northwest.

Grassland habitat of the present type was absent from the basin during the last major Pleistocene pluvial as were those amphibians, reptiles, and mammals closely associated with this habitat. An effort has been made to determine which of these vertebrates invaded the area from the northwest in post-pluvial time and which have entered the basin via relatively low-lying areas along the …

A Comparative Study Of Gross Pelvic Anatomy And Renal Histology Of Two Species Of Sparrows, Shirley Ann Hoskins

University of the Pacific Theses and Dissertations

While in no way passing judgments on the quality of the investigations which have been published, there is one conclusion that must be reached and this is that there is room for further investigations. The studies which form the basis of this paper were undertaken to widen the general range of information on the avian kidney and its associated osseous cradle. In addition to the discussion, numerous photographs and diagrams are submitted to clarify and support the text. The present paper deals with with kidney and pelvic girdle of two species of sparrow: Zonotrichia leucophrys and Passer domesticus.

Some Effects Of Photoperiodicity On The Temperatures And Weights Of Bobwhites, Bernard J. Cripps

Masters Theses

Introduction

In recent years there have been a number of studies that have dealt with body temperature and body weight variations in gallinaceous birds under various field or controlled conditions. Wilson (1948) studied the reactions of pullets to different environmental temperatures. In a laboratory experiment Bajpai (1962) observed that a change in the cloacal temperature of adult Rhode Island Red males was effected by manipulating the photo-period. In a report on the sexual maturation of Coturnix quail Wilson et al. (1962) discussed several aspects of variation in body weight, which resulted from changes in photo-period. Hamilton (1957) studied the weights …

An Investigation Of The Influence Of The Suprapharyngeal Ganglia Upon Water Balance And On Osmoregulation In Lumbricus Terrestris, Richard M. Dennany

Masters Theses

Chapter I

Introduction

In the central nervous system of most animals which have been examined some neurons show cytological characteristics of gland cells. These cells are now recognized as a specialized cell type and designated neurosecretory cells.

These neurosecretory cells are capable of elaborating secretory material which is accumulated as granules in the body of the nerve cell and in the axon-endings. They release complex organic substances, neurohormones, which act as hormones and are often liberated into the blood stream (Welsh, 1958). These specialized neurons are capable of receiving impulses from other neurons although their axons do not end in …

Comparative Myology Of The Pectoral Girdle Of Microtus Pennsylvanicus And Pedomys Ochrogaster, Marie Hagerman

Masters Theses

Introduction

The meadow vole Microtus pennsylvanicus (Ord) and the prairie vole, Pedomys ochrogaster (Wagner) are two species of grassland-dwelling, slightly fossorial rodents which are very similar in appearance and general body size and proportions. The objective of this study was to prepare a detailed description of the muscles of the pectoral girdle of M. pennsylvanicus and to compare them to P. ochrogaster. It was hoped that the study might indicate similarities and dissimilarities in the ways in which the two species have adapted to their mode of life and show whether or not they share common adaptations of the pectoral …

Studies Of Cs137 Metabolism In Several Mammals During Cold Exposure And Hibernation, Yu-Chong Lin

Biology ETDs

Experiments were conducted to define the extent to which lowered body temperature changes biological half-time and distribution of radiosotopes in tissues.

Metabolism of radioisotopes may be expected to be temperature dependent as the metabolism of many electrolytes has been demonstrated to involve temperature dependent mechanisms such as enzymatic transfer.

The effect of temperature on Cs 137 distribution in the mammalian hibernator, Citellus lateralis (Golden mantled ground squirrels) was studied. Experiments were conducted at the whole body and tissue levels. Radioactivity was measured with a small animal gamma scintillation detector. Whole body counts of animals given a single intraperitoneal injection of …

Geographic Variation Of The Pocket Gopher Thomomys Bottae In The Rio Grande Valley Of New Mexico, Thomas H. Follingstad

Biology ETDs

The geographic variation of the pocket gopher Thomomys bottae in the Rio Grande Valley of New Mexico and Conejos County, Colorado were studied. The pocket gophers were collected and prepared as standard museum skins and skulls. Various dimensions of the pocket gophers are measured, treated statistically, and plotted as Dice squares. Four groups of geographically related and like-sized animals were noted. These groups could be associated with four previously described subspecies of T. bottae. It was possible to observe a correlation between the mean size of each sample of gophers and the soil type in which they were found. The …

Relation Between Use Of Lincomycin And Outgrowth Of Yeast, Howard W. Clapp

Masters Theses

Introduction

The use of antibiotics has increased the average life expectancy of mankind. They have prevented and cured infectious diseases that previously terminated in death. Consequently, recovery is often prompt and complete.

Though a benefit to mankind, the use of antibiotics in the treatment of infectious disease has also been accompanied by new problems. For example, treatment of a primary infection such as a bacterial pneumonitis with a broad spectrum antibiotic, may result in the death of some of the bacteria. More than one species of bacteria, however, are often found in the infected area. If such be the situation, …

The Water-Bath As A Tool In Evaluating Responses Of Small Mammals To Thermal Stress, John T. Yelverton

Biology ETDs

The rate of heat loss from an animal to the environment is dependent upon multiple factors. External or environmental factors include the temperature gradient between the animal end the environment, humidity, and air velocity. With a water-bath technique these variables are eliminated by keeping the skin temperature of the animal nearly equal to that of the water.

In this study Citellus lateralis vas the only animal able to endure hypothermic conditions (25 C water) in either swimming or confined states by increasing metabolic rate. It is apparent that Mesocricetus auratus and Dipodomys ordi are more dependent upon passive temperature regulation …

The Effects Of Cobalt-60 On A Desert Root System, Mary G. Mayes

Biology ETDs

Tribulus terrestris L. (T. terrestris) is a late summer annual inhabiting relatively dry areas of southwestern United States. In the more northern latitudes of the Southwest, seeds do not germinate until about the middle of July when both day and night temperatures are high and the seasonal rains have started. The vinelike plant grows prostrate with a prominent deep penetrating taproot and even-numbered, pinnately compound leaves. The leaflets vary from three to seven pairs, are oblong, entire, folding together along the leaf axis at night or in windy or unusually cool weather. The flowers are usually lemon yellow, solitary, and …

On The Behavioral Responses Of Free Uinta Ground Squirrels To Trapping, David F. Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biologists often trap animals to obtain information on them. If trapping is selective toward some animals, the information may be inaccurate. Most mammalogists know or suspect that their trapping techniques (reviewed by Hayne, 1949; and Stickel, 1954) contain sources of bias. Since trapping remains the only feasible way to obtain information on many animals, researchers have tried to discover sources of sampling error and refine their techniques. They have found that one major source of difficulty may lie in the behavior of animals. Individual animals seem to respond differently to trapping, both initially and through learning (Geis, 1955; Crowcroft and …

Some Effects Of Accumulated Radium On The Productivity Of Algae, Joseph W. Angelovic

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ionizing radiation from natural occurring radionuclides and cosmic rays has always been a part of man's environment, but at such low levels as to have had virtually no effect. However, with the advent of the atomic age and the advancement of nuclear technology, background activity has measurably increased all over the world. Fallout from nuclear weapons testing, wastes from nuclear reactors, and wastes from the milling of radioactive ores have all contributed to this increase. Due to this increase, many ecosystems and their individual components are now subjected to radiation levels as high as a million times natural background. What …

Canada Goose Production And Population Stability, Ogden Bay Waterfowl Management Area, Utah, Norman H. Dey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the development of Ogden Bay Waterfowl Management Area in 1937, the Canada goose (Branta canadesis moffitti) population increased to a peak in 1949 and then declined slightly. Nelson (1954) noted that the decrease in population was probably due to either a change in habitat or increased hunting pressure. In recent years, direct band returns have indicated a high mortality rate in the population. This project was initiated to determine the relative stability of the Canada goose population and to measure, as closely as possible, the effect of a high mortality rate upon the nesting population.

Respiration Studies Of Rattus Rattus And Citellus Lateralis Brain Tissue Slices At 20 And 37 C, Sonja Hyduke

Biology ETDs

The purpose of this study is to investigate the extent of temperature and substrate dependence of brain tissue metabolism in hibernating animals. Possible cellular adaptations to low temperatures may indicate mechanisms possessed by the hibernator to maintain neural functions at low temperature. Oxygen consumption of brain tissue slices from homeothermic rats and active and hibernating ground squirrels (Citellus lateralis) was to describe the effect of temperature on rates of utilization of several substrates.

Ecology Of Summer Aquatic Invertebrate Populations In A Marsh Area Of Utah Lake, David A. White

Theses and Dissertations

Mud Lake marsh lies east of Utah Lake between the cities of Provo and Springville in Utah County. Since 1936 it has become a polluted, odiferous, silted area. A study was conducted on the aquatic invertebrates during the summer of 1962 (June 19 to September 20). An .01 meter2 bottom sampler was used at 30 random stations. Each station was sampled once a week. Water depth, mud, water and air temperatures were taken at each station. Dissolved oxygen (Winkler method) and ion resistance (Wheatstone bridge) were taken each day. The aquatic invertebrate community consisted of benthic (Diptera, Oligochaeta, Nematoda), interphashic …
