A Study Of Certain Community Relationships Of Eriogonum Corymbosum Benth In Dc In The Uintah Basin, Utah, Jack D. Brotherson

Theses and Dissertations

Eriogonum corymbosum Benth. in DC is a low-growing perennial shrub which is found in many cold temperate desert shrub regions of Colorado, Utah, and Nevada.. It is a species which grows on numerous soil types and/or geological formations. Specific objectives of the investigation were to study and describe certain community relationships of ten different plant communities where E. corymbosum was found. Each community was sampled to determine the amount of ground cover, percent composition, frequency, and density of each participating species. Physical site factors viz. soil texture, total soluble salts, pH, cation exchange capacity, and amount of calcium, magnesium, potassium, …


Changes In Hemoglobin During Metamorphosis Of The Salamander, Harvey Dee Mecham Aug 1967

Changes In Hemoglobin During Metamorphosis Of The Salamander, Harvey Dee Mecham

Theses and Dissertations

Analysis of hemogobins were conducted on animals of the species Ambystoma tigrinum. Separation of hemoglobin types was performed with a Carboxy-methyl-cellulose column (6 X 50 mm.) and pH gradient (pH 6 thru 8) of .01 M phosphate buffer. The hemoglobins in the effluent were detected and analysed with a micro-flow cell in a Beck-man DB-G spectrophotometer attached to a Photovolt Varicord 43 recorder. Two major components of hemoglobin were observed: larval and adult. These two components varied in concentration with the stage of development of the individual. In addition, it was noted that minor peaks ansd shoulders appeared on each …


A Comparative Study Of The Sulfhydryl Groups In The Gastrocnemius Of The Normal And X-Irradiated Pet Mouse, Robert Edward Shervette Aug 1967

A Comparative Study Of The Sulfhydryl Groups In The Gastrocnemius Of The Normal And X-Irradiated Pet Mouse, Robert Edward Shervette

Master's Theses

It has been recognized that hyperpigmentation of the skin is the result of eliminating the. -SH inhibition when treatment is by x-irraidiation. The results of a. study by fieams and Schaeffer indicate : a progressive increase of melanocytes in the skin with an increasing dosage of x-irradiation. However, it was also noted that the effect of x-irradiatin on the gastrocnemius of the PET mouse resulted in a decrease in the number of intramuscular melanocytes. The present study was designed to determine whether the changes in the x-irradiated muscle is related to possible changes in -SH concentration.The technique employed is a …


The Ultrastructure Of The Vibratory Muscle Of Crotalus Horridus, Louis Pastore Aug 1967

The Ultrastructure Of The Vibratory Muscle Of Crotalus Horridus, Louis Pastore

Master's Theses

A comparison of the vibratory and epaxial muscles of Crotalus horridus horridus Linnaeus wa smade. muscle fibers, fibrils, filaments, mitochondria and sarcoplasmic reticulum were described in this study. The sarcomeres of the epaxial muscle were almost three times the length of those of the vibratory muscle. The A band was observed to be about twice the length of the I band in the vibratory muscle. As seen in cross section the vibratory muscle had fibrils arranged in discrete packets with a limited number of thick myofilaments. In contrast, the fibrils of epaxial muscle were less conspicuously separated from each other …


Hematological Variation Associated With Altitude, Season, Sexual Activity And Body In The Uinta Ground Squirrel, Ralph Theodore Kinchloe Aug 1967

Hematological Variation Associated With Altitude, Season, Sexual Activity And Body In The Uinta Ground Squirrel, Ralph Theodore Kinchloe

Theses and Dissertations

Hematological comparisons were made on the Uinta ground squirrel (Citellus armatus) trapped at different altitudes and during vari ou s stages of seasonal activity in 1965 and 1966. Hematological variation due to sex, sexual activity and body weight were also analyzed. Ground squirrels were secured from the Mt. Timpanogos area near Provo, Utah County, Utah. Erythrocyte count, hematocrit, total blood hemoglobin, mean erythrocyte volume, mean erythrocyte hemoglobin and reticulocyte counts were measured using standard procedures; banding patterns of hemoglobin and serum proteins wer e determined by means of electrophoresis with polyacetate strips.


An Electrophoretic And Chromatographic Study Of The Hemoglobin From Adult And Fetal Pigs, Donald William Green Aug 1967

An Electrophoretic And Chromatographic Study Of The Hemoglobin From Adult And Fetal Pigs, Donald William Green

Theses and Dissertations

Hemoglobin, from the erythrocytes of adult and fetal pigs, was isolated and analyzed by carboxymethylcellulose column chromatography and electrophoresis on polyacetate. These techniques demonstrate the existence of four fetal components (F0, F1A, F1B, F1C) and two adult components (A0, A1) based on their elution pH values and electrophoretic mobilities. The shift from-fetal to adult forms is initiated sometime between eight weeks after birth and one year. The change is not completed until sometime after one year and the major fetal forms (F0, F1A) maintain a 15% level in a mature adult. This report is in contrast with the results of …

The Status Of The Common Crow Corvus Brachyrhynchos Brehm In The Great Basin, Gerald Low Richards Aug 1967

The Status Of The Common Crow Corvus Brachyrhynchos Brehm In The Great Basin, Gerald Low Richards

Theses and Dissertations

Due to a lack of taxonomic and distributional information concerning the Common Crow Corvus brachryhynchos Brehm inhabiting the Great Basin of North America, Johnston (1961) in one of the most recent revisions on crows, was unable to include this area in his work. Between 1965 and 1967, field trips were taken throughout the Great Basin to secure specims, and to determine to what extent the area was being utilized by crows. Ecological information such as habitat prference, nesting behavior, and interactions with other species was collected where possible. Forty-eight birds were collected from the Great Basin. From a comparison of …

A Study Of Hybridization And Behavioral Characters In Percina Notogramma (Rany And Hubbs) And Percina Peltata (Stauffer), Family Percidae, Jules J. Loos Jul 1967

A Study Of Hybridization And Behavioral Characters In Percina Notogramma (Rany And Hubbs) And Percina Peltata (Stauffer), Family Percidae, Jules J. Loos

Master's Theses

In view of the close phylogenetic relationship between the two sym­patric species of darters, Percina notogramma (Raney and Hubbs) and Percina peltata (Stauffer), placed in the subgenus Alvordius by Bailey and Gosline (1955), it is of interest to compare them in more detail than has been done in the past. Percina notograrnma occurs only in the Chesapeake Drainage in Virginia, Maryland and West Virginia whereas P. peltata ranges from Virginia to New York. Adequate comparisons of their external. morphological characters have been presented by Raney and Hubbs (1948) in their original description of P. notogramma. Supplementary data were provided by …


Electrical Response Of Frog Skin Epidermis To Sodium Ions, James H. Martin Jul 1967

Electrical Response Of Frog Skin Epidermis To Sodium Ions, James H. Martin

Master's Theses

Presently, the theory is held that the total frog skin potential (P.D.) is generated within the epidermis at two borders, the "outer border" and the "inner border, " which are said to be specifically permeable to Na+ and K+, respec­tively. This thesis concerns itself only with the electrical response of the "outer border" to varying Na+ concentrations in the solutions at the epidermis, [Na+]o. Contrary to expectation from the Nernst equation, the P.D. changes by only 17 to 35 mV, instead of theoretically 58 mV upon a 10 fold change in [Na …


Respiratory Activity Of Vibratory, Tail Epaxial And Midbody Expaxial Muscle In Crotalus Horridus, Aqkistrodon Contortrix, And Thamophis Sirtalis., James E. Forbes Jul 1967

Respiratory Activity Of Vibratory, Tail Epaxial And Midbody Expaxial Muscle In Crotalus Horridus, Aqkistrodon Contortrix, And Thamophis Sirtalis., James E. Forbes

Master's Theses

The purpose of this study was to determine if the muscles associated with tail vibration in snakes are physiologically specialized for vibration. Timber rattle­ snakes (Crotalus horridus) , copperheads (Agkistrodon contortrix) and garter snakes (Thamnophis sirtalis) were used. The copperhead represented a species which vibrates its tail but has no vibratory apparatus comparable to that of the rattlesnake. The garter snake does not vibrate its tail. A comparison of respiratory activities was made between the vibratory and tail epaxial muscle and the mid­ body epaxial muscle within and between the three species. Oxygen consumption of teased muscle fibers and muscle …
