A study of the humus content and the water content of San Saba clay and Denton clay. Studies show that the physical properties of soil are conducive to moisture retention and the availability of moisture to plants.

This thesis describes the growth and feeding habits of large mouth bass (Huro salmoides) as observed in North Texas.

This thesis presents the results of a three year study devoted to discovering the life and phenomena found in Lake Worth near Fort Worth, Texas.

This thesis presents the results of an investigation conducted to determine the maturation stages and chromosomal composition of the Homophron americanum (Sand Beetle) found in North Texas.

This study is an attempt to determine the relationship between humus and the water found in it and how both effect soil in Denton county, Texas.

This thesis presents the results of an examination conducted to determine the status of mourning doves in Throckmorton County, Texas.

This thesis explores the feeding habits of sunfish and bluegill in Texas lakes. Data gathered for this study is aimed to aid conservation of these pan fish by making a contribution toward a greater life history understanding of each species.

This thesis describes the vertical distribution, quality, and quantity of the fauna found at the bottom of Lake Worth in Texas.

The average level of sexual knowledge and attitudes about sexual situations among surveyed high school seniors in Gregg County, Texas are presented in this thesis.

This thesis resulted from an examination of Lake Worth plankton in comparison to plankton found in similar bodies of water throughout the United States.

A study of hypersensitivity of high school students to the oleoresins of fifty common North Texas plants.

This thesis presents a comparison of zoos and zoological gardens in the United States, Europe, and Asia. After an examination of these entities, the appeal and educational value of particular species is determined.

Etheostoma spectabile, E. punctulatum, and Cottus carolinae were sampled Mar., 1983, - Feb., 1984, in Flint Creek, Oklahoma. Immature E. spectabile ate primarily microcrustaceans, while mature fishes relied more on mayflies and amphipods. Juvenile E. punctulatum fed upon mayflies, amphipods, and Asellus. Mature E. punctulatum ate primarily mayflies, and other relatively larger prey. Cottus carolinae consumed chironomids almost exclusively in Jan. - Feb., 1984, while mayflies were predominant the remainder of the year. No significant habitat partitioning between the two darters, and seasonal habitat segregation between C. carolinae and the two darters was found. Dietary overlap between the darters was significantly correlated (p<0.0005) to differences in x prey sizes.

The purpose of this research was to determine the relationship of the slime layer antigen(s) to the "101" or LPS antigens and to attempt to evaluate the role of antibodies against the latter in protection against experimental infections in mice with the homologous strain of Pseudomonas aeruginosa. Results from agglutination tests, chromatographic separations, passive protection tests, and characterizations of the antigens by gel double diffusion do not support the concept that LPS is a necessary portion of the immunogenic material. The immunogenicity of LPS can be attributed to co-purification of residual amounts of slime layer antigens on the washed cells from which LPS was extracted.
