The Pattern Of Esterase Variation In The Mimulus Glabratus Complex (Scrophulariaceae), Sun Szen Hsu, Robert K. Vickery Jr. Mar 1976

The Pattern Of Esterase Variation In The Mimulus Glabratus Complex (Scrophulariaceae), Sun Szen Hsu, Robert K. Vickery Jr.

Great Basin Naturalist

Disc gel electrophoretic assays of Mimulus plants showed young stems to contain at least 15 esterase bands. The 6 bands in the center of the gels were highly reproducible. Eighty-one populations representative of all the cytotaxonomic groups and of the Western Hemisphere geographic range of the Mimulus glabratus complex were assayed for those 6 bands. There was no apparent correlation between the distribution of the esterase bands and important environmental parameters such as elevation and latitude. Hence, their distribution did not appear to reflect environmental adaptive values. Each population was monophonic for its particular combination and intensity of esterase bands …

The Comparative Toxicity Of Developmental Inhibitors And Organophosphates On Mosquitoes, Richard L. Orr Feb 1976

The Comparative Toxicity Of Developmental Inhibitors And Organophosphates On Mosquitoes, Richard L. Orr

Theses and Dissertations

Four developmental inhibitors (Altosid, Altozar, ZR-619 and ZR-777) and two organophosphates (Parathion and Abate) were tested on Aedes aegypti under laboratory conditions. When applied to fourth-instar larvae, the organophosphates were more toxic than the developmental inhibitors. Concentrations required for standard kills (LC50 and LC95) were lower for Altosid and ZR-619 than for Altozar and ZR-777. Field applications of Altosid SR-10 controlled Culiseta inornata for two weeks at 4 ounces per acre. With the exception of Dolichopodidae, most non-target aquatic organisms showed little response to Altosid SR-10. Although the developmental inhibitors Altosid and ZR-619 require higher concentrations for mosquito control, they …

New Hope: A Mormon Colony In Central California, Clint Mccready Jan 1976

New Hope: A Mormon Colony In Central California, Clint Mccready

Theses and Dissertations

New Hope was a small Mormon agricultural community in Central California. It was founded in 1846, by Samuel Brannan, on the hope that Brigham Young would make it the center stake of The Church of Jesus Christ of Latter-day Saints. The approximately twenty farmers at New Hope labored diligently under the illusion that thousands of their brethren would shortly join them. When President Young decided to settle in the Great Basin, the New Hope settlement was terminated that same year: 1847.

Orem, Utah: A Study In Urban Land Use, George G. Shaw Jan 1976

Orem, Utah: A Study In Urban Land Use, George G. Shaw

Theses and Dissertations

Orem, Utah, is a rapidly growing city that is changing from rural to urban land uses. A present inventory of land is important in determining the land use characteristics of the city, the degree of development, and future use of land. A field survey was made of the city and the resultant land use information was computerized for data analysis.

Although Orem City is rapidly changing to urban uses, the city is still largely undeveloped, especially when compared to major urban centers. Agriculture is still the most dominant use of land comprising almost thirty-nine percent of the city. Approximately forty …

The Impact Of Polygamy Upon The Life Of James Yorgason: A Nineteenth-Century Mormon Bishop, Blaine M. Yorgason Jan 1976

The Impact Of Polygamy Upon The Life Of James Yorgason: A Nineteenth-Century Mormon Bishop, Blaine M. Yorgason

Theses and Dissertations

On August 2, 1875, James Yorgason, soon to be the Bishop of the Fountain Green Utah Ward of the Church of Jesus Christ of Latter-day Saints, took his first plural wife. In doing so he joined a rather elite group of Mormon men who were known as polygamists. Over the next thirteen years, as he built a financial empire to support them, he took five more plural wives, making him exceptional even among the elite.
But then in 1887 the Edmunds-Tucker law was passed and "The Raid" against Mormon polygamists began, the United States entered a time of monetary crisis …

Reproductive Cycle Of The Belding Ground Squirrel (Spermophilus Beldingi Beldingi): Seasonal And Age Differences, Martin L. Morton, John S. Gallup Dec 1975

Reproductive Cycle Of The Belding Ground Squirrel (Spermophilus Beldingi Beldingi): Seasonal And Age Differences, Martin L. Morton, John S. Gallup

Great Basin Naturalist

The reproductive cycle in Belding ground squirrels was studied in the Sierra Nevada Mountains at two locations, one at 2,100 m elevation, the other at 3,000 m. Adults emerged from hibernation completely prepared physiologically for reproduction. Males tended to emerge slightly ahead of females and yearlings tended to emerge later than adults. Yearling females were fertile but produced smaller litters than adults, 4.48 vs. 6.31. Yearling males were infertile. They exhibited a slight seasonal cycle in testicular growth but did not reach sexual maturity. Testicular growth and spermatogenesis were incipient in many adults and in yearlings prior to hibernation.

Sexual Dimorphism In Malpighian Tubules Of Pteronarcys Californica Newport (Plecoptera), Ralph R. Hathaway Dec 1975

Sexual Dimorphism In Malpighian Tubules Of Pteronarcys Californica Newport (Plecoptera), Ralph R. Hathaway

Great Basin Naturalist

The Malpighian tubules in female nymphs and adults of Pteronarcys californica Newport are larger and whiter than in males. This difference is detectable in nymphs as small as 300 mg in live weight (final instar nymphs weigh 800 to 1600 mg depending on sex), and is most pronounced in late nymphs and adults. These differences are thought to be related to the increased excretory load imposed by the synthesis of ooplasm in the late female nymph and adult.

Efficacy Of Bunamidine Hydrochloride Against Immature And Mature Stages Of Echinococcus Granulosus, Lauritz A. Jensen Dec 1975

Efficacy Of Bunamidine Hydrochloride Against Immature And Mature Stages Of Echinococcus Granulosus, Lauritz A. Jensen

Theses and Dissertations

A study was conducted to determine the efficacy of bunamidine hydrochloride against the immature and mature stages of Echinococcus granulosus found in Utah. Twenty-seven dogs were obtained from local animal shelters and experimentally infected with the parasite. The drug was given at dosage levels of 25 mg/kg to 50 mg/kg of bodyweight. It was from 85.9 to 98.8% effective against the immature stage, and 100% effective against the adult stage. The results suggest that this drug can feasibly be used under field conditions where hydatid disease is endemic.

Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton Oct 1975

Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton

Brigham Young University Science Bulletin, Biological Series

The results of an extensive survey of spinturnicid mites of bats from Venezuela are presented in this paper. Approximately 30,000 bats were collected from a wide variety of life zones and localities. A representative sample was searched for ectoparasites. There are 3 genera of the family Spinturnicidae in Venezuela: Cameronieta, Periglischrus, and Spinturnix. Three previously described species of Cameronieta were found in the Venezuelan collection. Of the 7 species of Spinturnix previously described from the New World, 4 are reported from Venezuela. The genus Periglischrus constitutes by far the most significant segment of the Venezuelan collection. It is represented by …

Photoperiodic Responses Of Phenologically Aberrant Populations Of Pierid Butterflies (Lepidoptera), Arthur M. Shapiro Sep 1975

Photoperiodic Responses Of Phenologically Aberrant Populations Of Pierid Butterflies (Lepidoptera), Arthur M. Shapiro

Great Basin Naturalist

Two local pierid populations in western North America showing regionally aberrant phenologies were investigated in the laboratory. Neither a partially bivoltine Pieris napi from the Sierra Nevada foothills in El Dorado County, California (surrounded by univoltine populations), nor a vernal-univoltine P. occidentalis from a foothill outlier of the Colorado Front Range (below bivoltine populations) showed unusual responses to controlled developmental regimes in the laboratory. Their unusual phenologies are hypothesized to be the product of microclimate. Failure to undergo genetic adaptation to unusual microclimates is discussed with particular reference to the presence or absence of gene flow from nearby normal populations.

Body Size, Organ Size, And Sex Ratios In Adult And Yearling Belding Ground Squirrels, Martin L. Morton, Robert J. Parmer Sep 1975

Body Size, Organ Size, And Sex Ratios In Adult And Yearling Belding Ground Squirrels, Martin L. Morton, Robert J. Parmer

Great Basin Naturalist

A five-year study of Belding ground squirrels was conducted at high altitude in the Sierra Nevada. Body weight and body length varied seasonally depending upon the fat depletion-deposition cycle, age, and sex. Adult males tended to be heavier and longer than adult females, particularly in the last half of the active season. A similar pattern was present in yearlings. Yearling squirrels were often distinguishable from adults on the basis of body size. Mean body weights were greater in adults throughout the season, and mean body lengths were greater in adults through the first half of the season. Adults also had …

Invasion Of Big Sagebrush (Artemisia Tridentata) By White Fir (Abies Concolor) On The Southeastern Slopes Of The Warner Mountains, California, Thomas R. Vale Sep 1975

Invasion Of Big Sagebrush (Artemisia Tridentata) By White Fir (Abies Concolor) On The Southeastern Slopes Of The Warner Mountains, California, Thomas R. Vale

Great Basin Naturalist

White fir (Abies concolor) appears to be invading vegetation dominated by big sagebrush (Artemisia tridentata) on the southeastern slopes of the Warner Mountains of extreme northeastern California. The time of initial tree establishment within the shrubs was determined by increment borings. Possible causes of the invasion involving specific climatic conditions, fire history, and grazing use of the area during years of the establishment were explored. Heavy grazing by domestic livestock, particularly sheep, appears responsible for altering the sagebrush-grass vegetation and allowing tree invasion.
