Distribution And Abundance Of The Black-Billed Magpie (Pica Pica) In North America, Carl E. Bock, Larry W. Lepthien

Great Basin Naturalist

Analysis of Audubon Society Christmas bird count data and certain environmental variables shows the degree to which the Black-billed Magpie is a bird of cool arid regions in North America. The abundance and distribution of this species appear to be limited by two major climatic barriers: increasing summer temperatures in the Southwest and increasing summer humidity and precipitation on the central plains.

Seven species of Mallophaga have been previously reported from Venezuelan mammals. In this paper an additional 28 species and subspecies, 7 of which are new, are reported from Venezuela; and 21 other species which have not been previously reported from Venezuela are included because their hosts are found there.

The Effect Of Iron Supplementation On The Endurance Capacity Of The Female College Athlete, Barbara B. Sachon

Human Movement Studies & Special Education Theses & Dissertations

The major parameter of interest was the effect of iron supplementation on endurance capacity of female college athletes. Secondary parameters included the evaluation of the effect of iron supplementation on the following hematological variables: white blood cell count, red blood cell count, hemoglobin concentration, and hematocrit. Nineteen volunteer female students enrolled at the College of William and Mary in Williamsburg, Virginia served as subjects, All were members of the swimming team. All test trials and venipunctures were done at the women's gym at the College of William and Mary. There were two test periods.

All nineteen subjects performed a 500 …

The Effect Of Insulin, Fluoride And Methyl Xanthines On The Hypothalamic-Parotid Gland Endocrine Axis, Reagan Ondler

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine the effect of insulin and fluoride on dentinal fluid movement (FM) in high-sucrose fed rats as mediated through the hypothalamic-parotid gland endocrine axis. In conjunction with the fluoride study, the possible involvement of cAMP was examined through the use of several methyl xanthines which are recognized as phosphodiesterase inhibitors.

Twenty-one day old, male Sprague Dawley rats were maintained on a high-sugar diet (62% sucrose) for 8-9 days at which time intravenous or arterial infusions of insulin, fluoride or the methyl xanthines were performed. Additional procedures included collecting plasma from rats which had …

The Histology Of The Pineal Gland In Odocoileus Virginianus, Terry Michael De Villiers

Masters Theses

A total of 26 pineal glands from the white-tailed deer were histologically examined. Five different stains were utilized to determine various cell types present in pineal tissue. Connective tissue septa divide the pineal gland into incompletely separated lobules which are supplied by a very extensive vascular system. The pinealocyte is the most numerous cell in the gland and is most easily recognized by a prominent nucleus approximately 6-8 microns in diameter. The pinealocyte cytoplasm contains many minute granules. A distinct difference was noted in the histology of the oldest age deer pineal (age 7 years) when globular granules were observed …

The Effect Of Various Doses Of Caffeine Upon The Maximal Muscular Endurance Of College Females, Roberta Jane Perkins

Human Movement Studies & Special Education Theses & Dissertations

A limited number of investigations dealing with the effects of caffeine upon human physical performance have been conducted. Since caffeine is a central nervous system stimulant and it is a constituent of the popularly-consumed beverages - coffee, tea, and cola drinks, it would appear that numerous studies would have been conducted in order to determine the effect of caffeine upon human muscular performance. At any rate, there is a dearth of studies on this topic and the findings of the conducted experiments are equivocal and ambiguous.

The purpose of the present study was to determine the effects of various doses …

Bone Regeneration Over Submerged Dental Roots In Dogs, Roger Lee Plata

Loma Linda University Electronic Theses, Dissertations & Projects

Nonendodontically treated roots were submerged 1.5 to 2.0 mm. below the alveolar crest in three dogs. Twelve roots were treated in this manner. Regeneration of alveolar bone can be seen in three weeks with complete bone coverage in five weeks. A complete lamina dura can be seen around the amputated roots.

Bone failed to regenerate over two of the twelve roots. In one case there was delayed healing due to the early loss of some sutures. A sinus tract developed connecting the oral environment with the contents of the pulp. This led to bone resorption and a necrotic pulp. In …

The Dynamics Of Root Growth And The Partitioning Of Photosynthates In Cool Desert Shrubs, Osvaldo Alberto Fernandez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study addresses the nature of physiological and phenological evolutionary strategies of root growth dynamics and energy allocation followed by Atriplex confertifolia, Ceratoides lanata, and Artemisia tridentata growing in their natural cool desert environment.

Root observation chambers with inclined Plexiglass windows were installed in monospecific desert communities of Atriplex confertifolia, Ceratoides lanata and Artemisia tridentata. Soil temperature and water potential measurements taken immediately adjacent to the observation windows indicated a minimal disturbance was caused by the presence of these chambers. For the three species initiation of root growth was observed before initiation of shoot activity, furthermore, active root growth extended …

A Comparison Of Meteorologic Measurements From Irrigated And Non-Irrigated Plots, Provo, Ut, 1970–1972, Ferron L. Andersen, Phil D. Wright, J. Carl Fox

Brigham Young University Science Bulletin, Biological Series

A comparative study of micrometeorologic conditions on irrigated and non-irrigated pasture plots was conducted at Provo, Utah, from 1970 to 1972. Daily measurements were taken of the following: precipitation cither as rain or snow, new snowfall and total snow depth during the winter; relative humidity in a standard weather shelter; number of hours at maximum relative humidity; cloud cover each morning; potential evaporation; total wind 1 m above ground level; temperature extremes in a standard weather shelter; and temperatures both on irrigated and non-irrigated plots with sensing devices located 5 cm beneath soil surface under grass cover, at soil surface …

A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The heterogeneous nature of the collared lizards west of the Colorado River prompted this study. Samples from known populations of C. c. auriceps, C. c. baileyi, and C. c. fruscus were used as a base for defining the western populations. External morphology and cranial morphology were compared by cluster, canonical, and discriminant analyses.

Results of these analyses show a western complex of four populations which are distinct from the three base populations of the collaris complex. Members within the western complex are distinguishable with at least 90 percent reliability by discriminant analysis. Because of intergradation patterns seen in western Sonora, …

A Comparison Of Selected Isokinetic Training Velocities On The Development Of Muscular Power In College Women, Julia P. Knight

Human Movement Studies & Special Education Theses & Dissertations

The purpose of this study was to compare the effects of three different isokinetic velocities on the development of muscular power. Seventy-five college females were matched into four equal groups according to the average of their pre-test scores on the Vertical Power Jump Test and the Power Staircase Test. Group I served as the control group, while all 3 of the experimental groups performed the same isokinetic exercise at different pre-set rates of speed. Groups II, III and IV worked at the selected rates of .8, 2.3 and 3.9 inches per second respectively. All four groups were pre-tested and post-tested …
