Possible uses of North Texas Plants and Animals in Elementary Science
Date: May 1937
Creator: Millican, Addie
Description: This thesis aimed to study plants and animals of North Texas which are adaptable for use in elementary science. In this study, 15 groups of plants and animals were selected as representative ones and among other benefits, each group of organisms was examined for its contributions to a limited understanding of bilogical principles.

A Comparative Study of the Bottom Fauna of four Texas Lakes
Date: August 1938
Creator: Lamb, Leonard D.
Description: This thesis attempted to study the bottom productivity both qualitatively and quantitatively with reference to the distribution of bonthos. The study of the bottom fauna in large reservior lakes is a relatively new field. This work will give more information on an unknown field than previously existed, although its scope is not intend to be exhaustive.

A Study of Plankton Dilution in Source Streams Compared with that of Lake Dallas Proper
Date: August 1936
Creator: Evans, Archibald A.
Description: This study was a comparative study of Plankton of Lake Dallas and the three main source streams. Based on the analysis of data, which was presented relative to the organisms taken from the lake and from the source streams, the results obtained are discussed, the Plankton seem to be largely autogenetic in Lake Dallas, the source streams Elm Fork and Clear Creek form a dilution process.

A correlation of the Edaphic Factors with the Vegetation of the Woodbine sands, Denton County, Texas
Date: August 1936
Creator: Graham, H. L.
Description: The purpose of this study was to correlate the Vegetation of the Woodbine Sands with the edaphic factors. In the laboratory an analysis of the edephic factors was made of the twenty-two soil types collected from the three formations. The results of these and other analysis are shown in tables and graphs. The results indicate that the vegetational cover of an area that is uniform in its origin and in its resident soil factors is determined by the edaphic factors present.

Moisture Relations of the Soils of Denton County
Date: August 1936
Creator: Laufer, Hymie.
Description: In this research, study was made of representative soils of denton County (Texas) with the aim of correlating various soil-moisture factors through experimental analyses. Two accepted hypotheses of soil-moisture relations have been substantiated by experiment with Denton County soils.
