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.
