Population Studies of Ulmus Crassifolia in Flood-Plain Forests of Denton County, Texas

Koch, Linda S. 08 1900 (has links)
The problem with which this investigation was concerned was the comparison of cedar elm populations in different stands along creeks in Denton County, Texas, and the relationship of certain population parameters to various substrates present at stand sites, Parameters investigated eluded average basal area, basal-area density, transect-segment density, intertree distance, lateral distance, frequency, diameter breast-high, diameter breast-high size-class distribution, and immature-tree density. Variations among populations of Ulmus crassifolia Nutt were noted and analyzed in terms of soil particle size and existing community conditions.

Seasonal Survey of Actinomycetes in Twenty Denton County, Texas, Soils

Hudgins, Gladys 01 1900 (has links)
This investigation has had for its aim a further study of actinomycete flora of twenty Denton County, Texas, soils. The problem has evolved itself into, first, a seasonal analysis for the number of actinomycetes in each of the twenty soils; second, a determination of the types of soils that contain the greatest number of actinomycetes in each cultivated and uncultivated land; third, a determination of soil moisture and pH; and fourth, an attempt to correlate these factors with the number of actinomycetes found in each soil type.

Retail Change and Light Rail: an Exploration of Business Location Changes Accompanying Commuter Rail Development in Denton County, Texas

Yarbrough, Trevor S. 08 1900 (has links)
Within the past few decades, commuter rail routes in several major metropolitan areas have been implemented to provide an alternative to automobile transportation. Urban planners in these cities are looking to commuter rail to mitigate congestion and pollution. However, research on the impacts of commuter rail development on the surrounding retail landscape is still needed. In metropolitan Dallas-Fort Worth, the Denton County Transportation Authority recently opened its new A-Train light rail service linking suburban Denton and downtown Dallas. This thesis examines urban changes that occurred in the years before and after the A-Train line's 2011 opening, with a focus on restaurant and retail development in the vicinity of the A-Train stations in Denton County. This analysis evaluates changes in retail density and type, the population surrounding stations, and municipal initiatives that shape the retail landscape of station vicinities. This was done by gathering field data, retailer listings, population data, and conducting interviews with local businesses and city planners. The findings suggest that A-train stations have had a differential impact on the surrounding landscape, depending on the existing retail landscape, the types of retailers present, and the current state of municipal infrastructure that promotes accessibility. Overall, results suggest that urban planners play a vital role in harnessing the potential of commuter rail to promote nearby retail growth.

Determining the Suitability of Functional Landscapes and Wildlife Corridors Utilizing Conservation GIS Methods in Denton County, Texas.

Sales, Joshua 08 1900 (has links)
Denton County's unique cultural and natural landscape has undergone dramatic transformations during the past two centuries due to agricultural, urban and suburban processes which accelerated the loss and removal of native habitat and wildlife. This research sought out to identify the remaining natural areas which retain their natural features and support wildlife. Research methodology included fundamental principles of Conservation Planning, Geographical Information Systems, and Habitat Evaluation Procedures for identifying remnant functional landscapes and wildlife corridors. The final results suggest that Denton County's rural landscape retains the functional properties and elements suitable for habitat conservation and wildlife corridors, while also pointing to the fundamental obstacles to conservation posed by continued growth and private landownership.

An environmental justice assessment of the light rail expansion in Denton County, Texas.

Moynihan, Colleen T. 08 1900 (has links)
This study analyzes the proposed passenger rail line expansion along US Interstate Highway 35 in Denton County, Texas. A multi-dimensional approach was used to investigate potential environmental justice (EJ) consequences from the expansion of the transportation corridor. This study used empirical and historical evidence to identify and prioritize sites for potential EJ concerns. Citizen participation in the decision making process was also evaluated. The findings of this research suggest that the southeast Denton community has the highest potential for environmental justice concerns. This study concludes by offering suggestions for an effective public participation process. These include the incorporation of a community's local history into an environmental justice assessment, and tailoring the public planning process to the demographics and culture of the residents.

A Case Study of Social Transformation in Medical Care at the Community Level

Lensing, Willene (Willene Crowell) 05 1900 (has links)
This descriptive case study of the transformation in medical care at the community level was carried out with a triangulation approach. Data from documents and surveys using both semi-structured and unstructured interviews were gathered to evaluate and explain how medical care delivery changed from a primarily public system to one predominantly private.

To Determine the Extent to Which the Denton County Library is Meeting the Recreational Reading Interests of the Elementary Pupils of the Rural Schools of Denton County, Texas

Lambert, Benjamin Carter 08 1900 (has links)
"In order to determine the extent to which the Denton County Free Library is meeting the needs of the elementary school children for recreational reading, an analysis was made of the reading interests of the elementary-school children of twelve common school districts of Denton County, Texas. The ages of these children ranged from nine to fourteen years. A second analysis was made by checking various acceptable authors in the field of children's reading interests as read by the children in this group and age level. This information was secured by having each child in the schools check the items listed in a school survey sheet. This information was tabulated and the results are shown in tables presented in Chapter III. A third analysis was made of library material found in the reading lists that were supplied by the county; and lastly, a comparison was made of the results of the last analysis with the two preceding ones." -- leaf 3

Identifying Cultural and Non-cultural Factors Affecting Litter Patterns in Hickory Creek, Texas

Carpenter, Evan S. 08 1900 (has links)
Plastic deposition in hydrological systems is a pervasive problem at all geographic scales from loci of pollution to global ocean circulation. Much attention has been devoted to plastic deposition in marine contexts, but little is known about inputs of plastics into local hydrological systems, such as streams. Any attempt to prevent plastic litter must confront people’s behaviors, so archaeological concepts are used to distinguish between various cultural inputs (e.g., littering) and non-cultural forces (e.g., stream transport) that affect litter patterns on the landscape. Litter surveys along Hickory Creek in Denton, TX, are used to assess these factors.
