The Effect Of Insect Damage On Indian Ricegrass (Oryzopsis Hymenoides) In Western Utah, Luis S. Guerra
The Effect Of Insect Damage On Indian Ricegrass (Oryzopsis Hymenoides) In Western Utah, Luis S. Guerra
Theses and Dissertations
Indian ricegrass at the Desert Range Experiment Station forty-seven miles west of Milford, Utah, is damaged by the larvae of Coenchroa illibella, Diatrae sp. and Typoceris ceraticornis, the latter being the most destructive. The biology of the insects and the extent of damage inflicted are discussed. Uninfested plants produced more new stems than infested plants. Plants having a basal diameter of 4 to 6.9 cm and 7 to 9.9 cm were the most frequently infested and, consequently, the most severely damaged.
Population Dynamics Of Fleas (Siphonaptera) On The Uinta Ground Squirrel, Spermophilus Armatus Kennicott, Dennis I. Anderson
Population Dynamics Of Fleas (Siphonaptera) On The Uinta Ground Squirrel, Spermophilus Armatus Kennicott, Dennis I. Anderson
Theses and Dissertations
The Uninta ground squirrel, Spermophilus armatus Kennicott, is the most abundant diurnal rodent in the Wasatch Mountains at the 7,000-9,000 foot level particularly in the campgrounds and picnic areas. Contact between man and the Uninta ground squirrel may be hazardous inasmuch as the causative agent of plague has been isolated from S. armatus and its flea parasites (Public Health Reports, 1937, 1938a, 1938b; Meyer, 1938; Byington, 1940; Allred, 1951; and Beck, 1955). Since these fleas are vectors of sylvatic plague and potential vectors of human plague, detailed knowledge about their population dynamics is desirable.
The Effects Of Channelization And Water Impoundment On The Macroinvertebrates In The Weber River, Summit County, Utah, Parley V. Winger
The Effects Of Channelization And Water Impoundment On The Macroinvertebrates In The Weber River, Summit County, Utah, Parley V. Winger
Theses and Dissertations
Macroinvertebrate populations in the Weber River, Summit County, Utah, were analyzed to determine what effects channelization resulting from Interstate-80 construction and water impoundment had on the standing crop, species diversity and species composition. Bottom samples were collected monthly from riffle areas in channeled and unchanneled sections and above Echo and Wanship Reservoirs. Macroinvertebrate populations in the channeled areas were similar in standing crop, species diversity and species composition to those in unchanged areas within six months following channelization. Species diversities were higher (d=4.1, 3.7) above the reservoirs than below (d=2.0). The reservoirs restricted the distribution of several species of macroinvertebrates. …

Helminths Of Sceloporus Lizards In The Great Basin And Upper Colorado Plateau Of Utah, Richard Carlyle Pearce
Helminths Of Sceloporus Lizards In The Great Basin And Upper Colorado Plateau Of Utah, Richard Carlyle Pearce
Theses and Dissertations
This study was prompted by the scarcity of information on helminths in Sceloporus lizards of Utah. It reports these worms and includes references to parasites of reptiles in the appendix. A microscopic examination of the coelom, mesenteries, liver, lungs, esophagus, stomach, and intestines of 55 lizards was made, but helminths were recovered only from stomachs and intestines. Examination of S. graciosus yielded Opchoristica scelopori, a cestode found in the duodenum, and Cyrtosomum penneri, C. readi, and C. heynemani, three nematodes of the cecum. The latter two are new nematodes for this host species. Examination of S. undulatus yielded three new …
Vegetation Changes Following Fire In The Pinyon-Juniper Type Of West Central Utah, Milo Arnel Barney
Vegetation Changes Following Fire In The Pinyon-Juniper Type Of West Central Utah, Milo Arnel Barney
Theses and Dissertations
A total of 28 burn areas, that varied in age from 3-100+- years, were analyzed in a study of succession following fire, in the pin yon-juniper woodlands of west central Utah. Data were collected by means of the line-point and quadrat methods. These data were subjected to a multiple regression analysis. Canopy cover, basal area (sq. ft./acre) and density (trees/acre) of juniper were highly correlated with age of burn. Percentage dead sagebrush was found to be positively correlated with density of junipers. The stages of succession following fire began with weedy annuals, that reached a peak within 3-4 years. Juniper …
The Bottom Fauna Of Fish Lake, Utah And Its Relationship To The Trout Fishery, Dennis L. Shirley
The Bottom Fauna Of Fish Lake, Utah And Its Relationship To The Trout Fishery, Dennis L. Shirley
Theses and Dissertations
One-hundred and three bottom samples taken at Fish Lake, Utah from July, 1969 to June, 1970 were analyzed to determine the abundance, distribution, and standing crop of the bottom fauna species and to relate their availability to the amount of food eaten by the trout. Twenty-three taxa, representing three phyla and 19 families were collected. An amphipod, Gammarus limnaeus, in the littoral zone, and a tubificid worm, Rhyacodrilus coccineus, in the sublittoral and profundal zones, were the most abundant species. All 23 species were unevenly distributed in the littoral zone, whereas, only eight were found in the sublittoral and five …
Small Rodent Populations And Biomass In Three Sagebrush Communities Of Rush Valley, Utah, David W. Nichols
Small Rodent Populations And Biomass In Three Sagebrush Communities Of Rush Valley, Utah, David W. Nichols
Theses and Dissertations
Three desert Artemisia tridentata communities in Rush Valley, Utah were trapped for small rodents during the summer of 1970 in a mark-recapture study. Population densities were estimated using several indices for each population category. Animals were weighed and rodent biomass calculated for each species throughout the summer. Populations, biomass, and other data were then analyzed to gain a better understanding of A. tridentata community types of the Great Basin. Peromyscus maniculatus, Eutamias minimus, and Reithrodontomys megalotis were common to area 1. Peromyscus maniculatus, E. minimus, and Perognathus parvus were common to areas 2 and 3. The peak estimated standing crops …
An Evaluation Of Instructional Television In The Brigham Young University College Of Religious Instruction, James Frank Killian
An Evaluation Of Instructional Television In The Brigham Young University College Of Religious Instruction, James Frank Killian
Theses and Dissertations
The purpose of this study was to make an evaluation of Instructional Television in the College of Religious Instruction at the Brigham Young University.
The overall findings of the study indicate that there was much discontent manifest, from both students and faculty, with the present TV enrichment program. This discontent seemed to be strongest in the areas of the types of presentations made on TV, the quality of the productions, and that the TV presentations were required and not optional. The discontent was manifested by the fact that one third of the students did not attend half the TV enrichment …
The Development Of Municipal Government In The Territory Of Utah, Alvin Charles Koritz
The Development Of Municipal Government In The Territory Of Utah, Alvin Charles Koritz
Theses and Dissertations
In 1846 the Mormons were expelled westward from Nauvoo, Illinois. Beyond the borders of the United States, the Mormon Church absorbed the civil functions of municipal government, a pattern which continued in the Great Basin and received the sanction of state authority in 1849 under Deseret.
As the political arm of the "Kingdom of God," the Council of Fifty influenced local political development as its members simultaneously occupied elective offices in both the territorial legislature and municipal government.
During the first decade as a territory, Utah's city charters generally followed the pattern established by Nauvoo in 1840. However, in the …
Dixie Wine, Dennis R. Lancaster
Dixie Wine, Dennis R. Lancaster
Theses and Dissertations
The area along the Virgin River, known as Utah's Dixie, is ideal for the culture of grapes. To utilize the natural resources, provide a cash crop for the Dixie communities, and make wine to be used in the Sacrament service; Mormon Church leaders called several expert horticulturists and vinters to Dixie. Great amounts of wine were produced in Dixie. The Church became the largest producer due to the great amounts of grapes paid as tithing. Wine was used in the Sacrament, and was a common drink in Dixie.
The mines at Silver Reef were the principle market for Dixie wine. …
