A Comparative Study Of Crotaphytus Holbrook (Iguanidae), Wilbur Gerald Robinson

Theses and Dissertations

The anterior myology of Crotaphytus wislizeni and C. collaris is described in detail and a statistical analysis is made of the differences in the relative bone sizes, and the number of eggs per clutch, as well as other taxonomic characters previously applied to these species. The significant differences found with respect to the shape of the skull, that of the body, and the character of the hyoid are correlated with muscular development and habits of the two species. The descriptive material is accompanied by detailed myological and osteological illustrations of C. wislizeni. Comparative notes are made on C. reticulatus which …

Life History Of The Desert Wood Rat, Robert Carr Stones

Theses and Dissertations

A life history field study of the widespread desert wood rat, Neotoma lepida lepida Thomas, was conducted periodically from August, 1959, to June, 1960, eight miles west of Jericho, Juab County, Utah. An estimation of the density of houses and population density of wood rats throughout the general region, accomplished by charted guadrats and a plotless quarter method, revealed an average densityof 4.9 houses of 3.1 adult wood rats per acre in a juniper-sagebrush community of the type frequently found throughout the area. Live-trapping within a well-wooded juniper-sagebrush community (twenty-four acre area) revealed twenty-seven wood rats captured sixty-eight times for …

The Cattle Industry Of San Juan County, Utah, 1875-1900, Franklin D. Day

Theses and Dissertations

The purpose of this study was to learn the reasons for the movement of cattle Into San Juan County, Utah, the development of the Industry, and its contribution to the growth of the county.

The few written accounts in existence of the cattle industry in San Juan are brief and found in widely separate areas. The whole and complete account will likely never be written, but there is need for gathering as much of the scattered information as possible.

A study of the early history of the inhabitants of San Juan was made, along with an examination of the geography …

Studies On The Periodicity Of Certain Plankton Species Of Salem Lake, Gene A. Pratt

Theses and Dissertations

Plankton samples were taken periodically from one station in Salem Lake from the fall of 1955 through the winter of 1957. Other data including the pH, dissolved oxygen content, turbidity, brightness of day, temperature, and time of day were recorded at the time of each collection. The plankton samples were centrifuged and preserved in a 4% formalin solution. They were later examined microscopically, and density, percent density, and percent frequency calculations were made from them for ten selected species and for the five phyla which they represent.

The Incidence Of Nasal Mites In Over-Wintering Red-Wing Blackbirds In The Vicinity Of Utah Lake, Utah, George M. Talley

The Embryology Of The Paradise Fish, Macropodus Opercularis Linnaeus, Lewis M. Mulkay

Theses and Dissertations

The development of Sacropodus opercularis Linnaeus, (Perciformes: Anabantidae), is described from cleavage to five days post hatching. For the most part M. opercularis follows the pattern of typical teleostean development except as noted below: 1. The heart develops under the left eye along the anterior margin of the yolk sac. This is similar to that reported by Ingesoll (1951) for the Blue Gourami, Trichogaster trichopterus. 2. The ear develps from the head mesenchyme alongside the brain rather than from a placode. 3. The gut develops first in the posterior region then differentiates cephalad. It was also learned that: 1. No …
