A Comparison Of The Root Systems Of Bitterbrush And Cliffrose, Morris G. Cline
A Comparison Of The Root Systems Of Bitterbrush And Cliffrose, Morris G. Cline
Theses and Dissertations
A root study was undertaken to learn about bitterbrush (Purshia tridentata (Pursh) DC) and cliffrose (Cowania stansburiana torr.) to gain some clues, perhaps, as to the causes of their present distribution. In a period extending from July 1959 to July 1960, twenty-four plants were excavated on six different sites in the Wasatch foothill belt in Utah County, Utah. Root and some soil characteristics were analyzed, described and compared.
Observations On The Hibernation Of Culex Tarsalis Coquillett In Utah Valley, Utah, Dennis W. Trent
Observations On The Hibernation Of Culex Tarsalis Coquillett In Utah Valley, Utah, Dennis W. Trent
Theses and Dissertations
Culex tarsalis Coquillett is a common evening pest mosquito throughout the summer in most of temperate Western North America. Present evidence indicates this mosquito as the principal naturally infected vector of western equine encephalomyeltic (WEE) viruses. Certain interrelationships of WEE epidemiology and tarsalis bionomics are basically understood; however, in areas where winters are severe little is know of tarsalis hibernation, and the survival mechanism for WEE viruses in unknown. The purpose of this study, conducted from 1 September 1959 to 20 May 1960, was to gather ecological information on the hibernation of Culex tarsalis in Utah Valley, and secondly to …

Lichens Of The Wasatch Mountains In Central Utah, Harry Stewart Nielsen Jr.
Theses and Dissertations
The purpose of this study is to conduct an intensive investigation of the lichen flora of the Wasatch Mountains in central Utah. The approach followed is that of compiling into one account keys, descriptions, illustrations and ecological notes of lichens that are found in this region of the state.
The Aquatic Plants Of Central Utah And Their Distribution, Gerald E. Bessey
The Aquatic Plants Of Central Utah And Their Distribution, Gerald E. Bessey
Theses and Dissertations
It was the purpose of this study to determine what aquatic plants were common to central Utah and to outline the ecological factors that control their distribution. The main emphasis throughout has been upon the more macroscopic aquatic plants. Such algae were included as was warranted by their size,, abundance and importance in the various habitats in which they grew. As this study progressed it became evident that there was a need for a broad survey-type study of the aquatic plants that would include essentially all of the wet lands of the central Utah region. The area of study closely …
