A Taxonomic And Ecological Study Of The Desmids Of Lily Lake, James L. Pederson
A Taxonomic And Ecological Study Of The Desmids Of Lily Lake, James L. Pederson
Theses and Dissertations
During the summero f 1964 a taxonomica and ecological study was made of the desmids (microscopic green algae) found in Lily Lake. The study site is a subalpine lake in the Wasatch National Forest of the Uinta Mountains, Utah. The lake is located about one-half mile west of Trial Lake at an elevation of approximately 10,000 feet. The lake is an acidic, cold, lentic bog pond characteristic of this region. Desmids were collected at weekly intervals from seven sampling sites. The water temperature, pH, dissolved oxygen, light conditions and length of day from sunrise to sunset were recorded at the …
Winter Behavior And Population Dynamics Of American Eagles In Western Utah, Clyde C. Edwards
Winter Behavior And Population Dynamics Of American Eagles In Western Utah, Clyde C. Edwards
Theses and Dissertations
The large size, extensive range, and irnporta.nt corrnnunity role of the Golden Eagle (Aguila chrysaetos L.) and the Bald Eagle (Haliae-etus leucocephalus L.) attract considerable scientific interest. Sorne aspects of their life history have been investigated and reported in detail, but their rapidly declining numbers (Sprunt and Ligas 1966, Cottam 1961) necessitate new investigations into all phases of their life history and particularly into population dynamics.

Age And Growth Of White Bass, Roccus Chrysops (Rafinesque), In Mud Lake, Near Provo, Utah, Frederick Edward Trapnell
Theses and Dissertations
This study was conducted to obtain information that could be used in the management of the Utah and Mud lake white bass fishery. It also provides data for evaluating the effect of the loss of Mud Lake on the white bass utilizing it. Determination of age, growth rate, and coefficient of condition of the Mud lake white bass were objectives in this study. The occurrence of organisms in the digestive tracts of 64 white bass as well as the movement of white bass into and out of Mud Lake were also studied. Hoop nets, a continuous mesh gill net, and …

The Fisheries Of Deer Creek Reservoir, Utah, With Special Emphasis On The Yellow Perch (Perca Flavescens Mitchill), Gale R. Lewellen
Theses and Dissertations
This thesis is concerned with the fisheries of Deer Creek Reservoir, Wasatch County, Utah, with special emphasis on the yellow perch. The study period was from May 13 to November 24, 1968. Objectives included the determination of size, age, and food habits of the yellow perch. Parasitic occurrences in the perch population by Ligula intestinalis were also recorded as well as the utilization of the perch by the fishermen. Observations on other species of fish including an analysis of rainbow trout stocking programs were also objectives of this thesis. Data was gathered by means of creel census and fish collection …
A Study Of Aquatic Fungi In Powell's Slough, Chao-Chih Hsiao
A Study Of Aquatic Fungi In Powell's Slough, Chao-Chih Hsiao
Theses and Dissertations
Aquatic fungi in-Powell's Slough were.studied in 1967 & 1968. Collections were made and water temperature, oxygen content & pH values were measured at weekly intervals. For collections, wire baskets containing substrata were submerged in water for one month. After collecting, substrata were brought to the laboratory. Identification was based on the keys of Sparrow, 1960. Aquatic fungi identified included seven orders, nine families, fifteen genera, and thirty species, from thirty-three collections of fifteen types of substrata. The substrata used in this study were: (i) fruits: apples, rose hips, plums, pears, haws; (ii) twigs: poplar, weeping willow, river birch, weeping white …
