The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum Jun 1952

The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum

Theses and Dissertations

To an entomologist, the Orthoptera1 is in a state of confusion with respect to the available literature. Work has been done, and is now being done on the orthopteran fauna, but manuals tor identification of most species are not available for all sections or the country. Exclusive of a few lim-ited groups, Utah is among the areas that has no complete keys for taxonomic workers. In biological ivenstigations identification is essential: The species being studied must be definitely known. The primary purpose of this study, therefore, is to list the Utah Orthoptera and provide the keys necessary to their critical ...


An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield May 1952

An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield

All Graduate Theses and Dissertations

Turkey raising has become big business. During the period 1942 to 1946, the average annual return in Utah amounted to about nine and one half million dollars (4). This amount would have been increased considerably if the death loss among poults had been lower. As an example, using the percentages of mortality given by Miner (9, P. 5), it is estimated that the death-loss of turkeys in 1944 resulted in a loss of gross income by the farmers of Utah of more than four million dollars provided that the price the farmer received had remained the same.

All Graduate Theses and Dissertations

The California Quail is native to the coastal and semi-arid regions of California extending north into Oregon. Two subspecies are commonly recognized. the California Quail (Lophortyx californica brunnescens Ridgway), and the Valley Quail (Lophortyx californica californica Shaw) 0 The two forms are very similar in coloration and habits and, for the purpose of this study, no effort is made to distinguish the two.


The Consumptive Use Of Water In Milford Valley, Utah, Terrel R. Tovey May 1952

The Consumptive Use Of Water In Milford Valley, Utah, Terrel R. Tovey

All Graduate Theses and Dissertations

Consumptive use, as used in this thesis, is defined as the sum of the volumes of water used by the vegetative growth of a given area in transpiration and building of plant tissue and that evaporated from adjacent soil, snow, or intercepted precipitation of the area in any specified time, divided by the given area. If the unit of time is small, the consumptive use is expressed in acre-inches per acre or depth in inches, whereas, if the unit of time is large, such as growing season or a 12-month peiod, the consumptive use is expressed as acre-feet per acre ...
