A Descriptive Ecological Study of Selected First Admissions to a Private Psychiatric Hospital 1960 through 1963

Description: Following Hawley's point of view regarding the definition and inclusiveness of human ecology, ecological data must include both a population and its characteristics and some measurements of the environment of this population. Following Hawley, an ecological investigation must select from available data and examine at least some of the relationships that may exist among these measurable population and environmental characteristics, in an effort to find and isolate the causes of mental disorders, particularly of those now called "functional."

An Ecological Survey of the Herpetofauna of Palo Pinto County, Texas

Description: The purpose of this research was to compile a presence list of reptiles and amphibians that occur in Palo Pinto County, Texas, and to investigate the ecological distributions and zoogeographic affinities of these herpetiles. The study area was chosen primarily because of its location in North Central Texas and its rugged topography, which sets it apart from the surrounding area.

The Impact of Chinese Privet (Ligustrum Sinense) on the Survival and Re-Establishment of Native Plants at the Dallas Floodway Extension

Description: Invasive woody shrubs are a problem when they displace native species and threaten habitats, especially those that harbor rare or endangered species. They not only compete with native plants, but also alter habitat and food that many organisms depend upon. Invasive plants undergo a release from their specialist predators in the nonnative range, providing them advantages over native species. Because modes and pathways of how invasive species spread are not fully understood, predicting spread and implementing restoration ecological controls remain inexact. Due to the lack of comparative studies on woody shrubs, especially invasive privets, we understand very little about conditions affecting their invasiveness. A study was conducted near Dallas, Texas to determine if privet has allelopathic properties that influences growth of native plants. Soil nutrients and other analyses were made and compared between field plots supporting privet, plots in which privet has been removed, and plots where privet has not been observed. In some field plots, natives were planted under the three previously mentioned conditions, and their survival and condition were monitored to evaluate effects of privet on their establishment and growth. It was found that Chinese privet did hinder seed germination in red mulberry, soapberry and beautyberry and root formation in beautyberry cuttings. The soil in the sites were found to be normal for bottomland forests that endured two flooding events within one year.

An evaluative study of the grasslands of the R.J. McMurry Ranch, Denton County, Texas

Description: It is the purpose of this problem to classify the four major pastures of the McMurry ranch using the discussed classification system. The definite measurable qualities characterizing each condition of the system are used extensively in this study. The problem is concerned also with the observation of results of misuse, the present practices that could result in further depletion of portions of the McMurry ranch, and procedures being employed at the present time aimed toward the restoration of these depleted portions.

Wetlands: An Overview of Issues

Description: The report documents recent changes in wetland acres. The U.S. Fish and Wildlife Service released its most recent periodic survey of changes in wetland acreage nationwide in March 2006. Covering 1998 to 2004, it concluded that during this time period there was a small net gain in overall wetland acres for the first time that this survey has been conducted. Others caution, however, that much of this gain was in ponds, rather than natural wetlands.
