Nesting Ecology Of The Ferruginous Hawk (Buteo Regalis) In West-Central Utah, John Bradford Weston

Theses and Dissertations

During the spring seasons of 1967 and 1968 ecological studies were made of nesting Ferruginou.s Hawks (Buteo regalis) in a 325 square mile area in west-central Utah. In the springs of 1967 and 1968 a systematic search was conducted throughout the study area for Ferruginous Hawk nests. When active nests were located they were kept under observation throughout the study. The density of nesting pairs in 1967 and 1968 ranged from 7 to 15.4 square miles per pair. An annual seasonal displacement was exhibited, with Ferruginous Hawks being present in the study area only during the nesting season, which lasted …

Elevational Occurrence Of The Ticks Dermacentor Andersoni And Dermacentor Parumapertus In Utah County, Utah, William J. Despain

Theses and Dissertations

Considerable research on ticks has been done since it was discovered that the Rocky Mountain wood tick, Dermacentor andersoni Stiles, was a principal vector of Rocky Mountain spotted fevero Additional disease agents of man are also transmitted by D. andersoni. This tick and a closely related species, Dermacentor parumapertus Neuman, occur commonly in Utah. The two species are often closely associated, although D. andersoni is believed to occur in the mountains, whereas D. parumapertus is in the desert valleys. Diseases affecting animals in nature are transmitted by ticks of both species. Consequently, any interaction between the two may be influential …

A Taxonomic And Ecological Survey Of The Algae Of Lilly Lake, Ann C. Palmer

Theses and Dissertations

A taxonomic and ecological survey of the algae of Lilly Lake in the Uinta Mountains, Utah, was carried on from June 1967 to November 1967. The lake is a typical acid bog lake with an average pH range of 4.5 to 6.9. Extremes of pH in the alkaline range were present due to additional factors. Algae identified included 96 genera and 208 species. These were found in many different types of microenvironmental niches. The main factors which limited the algae to definite areas of the lake were pH, water temperature, light available, and type of substrate. The predominant algal genera …

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, …

An Ecological Study Of The Algae And Mosses Of Cascade Springs, Wasatch County, Utah, Deanna Lynn Mccoard

Theses and Dissertations

An ecological study was conducted at Cascade Springs, Wasatch county, Utah from August 1965, to June 1967. The algae and aquatic moss species were determined and ecological information about these organisms was obtained. Physical data were also collected: bicarbonates, carbonates, free carbon dioxide, hydroxides, oxygen, pH, and temperature. The physical environment of the water was found to be very constant. Tests taken at the different study sites were consistently similar, not only during each day, but all year around. No great variation of any kind was found in the water. In contrast to the water environment, the topography of the …

Investigations Into The Spawning Ecology Of The White Bass Roccus Chrysops, (Rafinesque) In Utah Lake, Utah, Frédérick Vinvent

Theses and Dissertations

Utah Lake, located in Utah County, north-central Utah, is one of the most important natural fishing lakes in the state. The spawning ecology of the white bass (Roccus chrysops) was studied in Utah Lake between 1964 and 1966. Gill nets and seining were the primary means of sampling. The spawning location was sampled every other day throughout the spring and early summer of 1966. Three major winter schooling areas were found: Provo Bay - Creer Access south to the mouth of Spanish Fork River, Lincoln Beach, and off Ludlow Barn. There appears to be extensive winter feeding and movement among …

Life History And Ecology Of The Colorado Chipmunk (Eutamias Quadrivittatus Hopiensis), Carl Eugene Wadsworth

Theses and Dissertations

Observations of reproductive behavior, growth and development of the young, food habits, habitat preference, and daily and seasonal activity patterns of the Colorado chipmunk are presented for the first time. The breeding cycle is as follows: mating occurs in late February or early March; the young are born in early to mid-April and first appear above ground in May, but do not reach breeding age until the following spring. There is only one litter of young per year. The mean number per litter was 5.7 for three litters born in captivity. The sex ratio of the animals born in captivity …

Summer Soil And Air Temperatures In Four Plant Communities, Paul W. Conrad

Theses and Dissertations

Temperature, one of the most influential factors controlling the growth and distribution of plants, was measured during a three month summer period within several stands of vegetation. The stands represented four distinct plant communities: sagebrush-grass, mountain brush, aspen, and conifer. Measurements were obtained by a sucrose inversion method which gave exponential average or effective mean temperature (eT) values. Registerants, small glass vials filled with a sucrose-buffer solution, were placed in the air 10 decimeters above the ground level and in the soil 1, 5, and 10 decimeters below the ground level. The sites were carefully described with respect to plant …

It provides not only a faunistic and floristic study of areas having a high and low surface radiation, but also includes a consideration of their general ecology. Major emphasis is placed on the variation of the external characteristics of the small vertebrates of these areas with a statistical analysis of those characters examined in the lizards. The study was conducted in southeastern Utah (Tanner 1963, see map) from October 1959 through 1964, and was conducted as a test of the variation effects of natural …

Tularemia And Deer Flies In The Environs Of Utah Lake, Utah, Kaye B. Cox

Theses and Dissertations

Deer flies have been implicated as mechanical veotors of tularemia in Utah. Although infected flies heretofore have not been tound in nature, there is little doubt of their importance in transmitting tularemia to man. Two species present in this area, Chrysops discalis Williston and Chrysops noctifer Osten Sacken, have been shown experimentally to transmit the disease. The presence of deer flies in the environs of Utah Lake where tularemia is endemic oftera a potential health threat to man, and the expanding human population and development ot recreational facilities adjacent to the lake inorease this potential. Despite the taot that deer …
