Sediment Phosphorus Cycling In A Managed System Irondequoit Bay, N.Y., Daniel J. White Dec 2006

Sediment Phosphorus Cycling In A Managed System Irondequoit Bay, N.Y., Daniel J. White

Biology Master’s Theses

The current status of internal phosphorus loading was evaluated in Irondequoit Bay, NY, an embayment of Lake Ontario. Sediment core incubation experiments and phosphorus water column profiles were used to quantify the release rate of phosphorus from the deepwater sediments of Irondequoit Bay during summer periods of low hypolimnetic oxygen. The top 25 cm of sediment cores collected monthly from May 2004 through September 2004 were analyzed for total phosphorus, total manganese, total iron, and total aluminum. Phosphorus fractionation of the sediment cores was determined through sequential extraction. Phosphorus water column data collected during the summer of 2003 and 2004 ...


A Comparison Of Created And Natural Wetlands And The Effect Of Landscape Characteristics On Vegetation, Amphibian And Bird Variables In Freshwater Marshes Of Upstate New York, David W. Porter Aug 2006

A Comparison Of Created And Natural Wetlands And The Effect Of Landscape Characteristics On Vegetation, Amphibian And Bird Variables In Freshwater Marshes Of Upstate New York, David W. Porter

Biology Master’s Theses

Wetlands provide a number of ecological and social functions, including flood abatement, improvement of water quality, recharge ground water and support for a great diversity of flora and fauna. Despite their many functions and values, wetlands have not always been appreciated. Since the 1780s, it is estimated that 53% of wetland acreage in the United States has been lost due to draining, filling and the subsequent development of land for roads or farms.

In 1972, the Clean Water Act (CWA) was established to try to reverse declining wetland acreage in the U.S. According to Section 404 of the CW ...


Evaluation Of The Basis And Effectiveness Of Habitat Assessments In Wetland Functional Assessment Methods, Amy Elizabeth Gardner May 2006

Evaluation Of The Basis And Effectiveness Of Habitat Assessments In Wetland Functional Assessment Methods, Amy Elizabeth Gardner

Biology Master’s Theses

I studied the basis and effectiveness of wetland assessment methods in providing habitat assessments. While it is well understood that wetlands and riparian areas provide important ecological functions and habitat for a wide variety of wildlife species, much is still to be learned about providing meaningful, accurate and repeatable methods for assessing them. I examined and evaluated four assessment methods to determine their accuracy and usefulness in assessing a site's provision of habitat.

One hypothesis I tested is that if the assessment methods studied provide an accurate assessment of wetland functions, then the resulting site scores for the methods ...
