The Relationship Between Weight Restoration and Maturity Fears in Women with Anorexica Nervosa

High maturity fears predict poor treatment outcomes in women with anorexia nervosa (AN). The purpose of this study was to determine if weight gain predicts decreases in maturity fears (MF) for AN patients. Fifty-six patients in an eating disorders partial hospitalization program were administered a series of psychological tests at intake and discharge. R2 values indicate that percent change in weight restoration will not accurately forecast the change in MF scores, although a positive trend was identified between the two variables. The weak predictive relationship suggests that weight restoration alone is not adequate to address the psychological components of AN.

Restoration Efforts and Prairie Dog Management at the Rocky Mountain Arsenal National Wildlife Refuge

The Rocky Mountain Arsenal National Wildlife Refuge is being re-seeded to native shortgrass prairie, but the effects of prairie dog colonization on some sites may be limiting successful native plant establishment. This Capstone Project compares vegetation monitoring data and prairie dog distributions in four refuge sites to evaluate the effects of prairie dog colonization on restoration. In general, native plant abundance has increased on study plots since initiation of restoration. Localized changes in plant abundance have occurred among transects, but prairie dog densities could not be correlated with the changes. Future prairie dog expansion is cause for concern due to intensified burrowing and grazing effects. Seven recommendations are presented to aid future restoration efforts.

The Rio Salado Riparian Habitat Restoration Area: Managing the Southwestern Willow Flycatcher

The following document identifies the impact to the current management plan of the Rio Salado Riparian Habitat Restoration Area in the event the endangered Southwestern Willow Flycatcher is found nesting at the project site. Rio Salado is managed by the City of Phoenix Parks and Recreation Department, and consists of a low-flow channel with native vegetation and wildlife along the Salt River. This paper analyzes the regulatory responsibilities of project site management and discusses the necessary adjustments to the management plan. Despite the current absence of the Southwestern Willow Flycatcher from Rio Salado, management should enter into a Safe Harbor Agreement with the U.S. Fish and Wildlife Service to legally protect themselves from the regulations stipulated in the Endangered Species Act.

Policy Development at a Local Level to Mitigate Depositing Endocrine Disruptors into Aquatic Ecosystems

Endocrine disruptors are suspected to cause disruption to organisms in aquatic environments. Intersex fish and skewed populations of females outnumbering males have been found where effluents from municipal wastewater treatment plants enter into receiving waters. The science needed to substantiate a link of these suspected pollutants as the cause of problems to human health or the environmental is in its infancy. Empirical research was used to identify suspected endocrine disruptors, their sources, and the difficulties involved in regulating these emerging contaminants. This project examined entities that are addressing endocrine disruption and provides cost-effective recommendations for municipalities to develop policies to mitigate the amount of endocrine disruptors entering into receiving waters and limiting the effects caused by endocrine disruption.

The Adequacy of Wildlife Management on an Endangered Species: A Design Template for Ecosystems Management in Alabama

The Alabama beach mouse (ABM) was listed an an endangered species in 1985. The ABM has been cited as being minimally managed since its listing. The Sierra Club points out the lack of Primary Consituent Elements (PCE) that are required by the Endangered Species Act of 1973. While traditional habitat status is mired in legal and bureaucratic delays, effective management remains less than optimal. Ecosystem management presents with it, new observable and technological tools that may present a panacea in the ABM's paradox. This Capstone looks at the possible implementation of an ecosystems management alternative in aiding the persistence of a small isolated and endangered species.

Mangrove, Crab and Shorebird Activity as Bioindicators to the Health Status of Mangrove Ecosystems along the Surinamese Coastline, South America

This study focused on the shorebird activity along the Surinamese coast in relation to the mangrove ecosystem health. The health of three estuarine mangrove areas was assessed using important bioindicators of the mangrove ecosystem: crabs, birds and mangroves. Mangrove vegetation was measured at Weg Naar Zee, Matapica canal delta and Coronie coast. Crab activity was measured by burrow and crab counts. Occurring shorebirds were also counted at these areas. The results show that mangrove regeneration and shorebird activity is significantly related to the health of the ecosystem. Weg Naar Zee was the most damaged and highest at risk. Matapica canal delta and the Coronie coast were the least damaged, with Coronie coast showing greatest health and biodiversity of the indicators.
