Water Quality Sampling and Monitoring of the Pawcatuck River Watershed

The Pawcatuck River and the Pawcatuck River Estuary and Little Narragansett Bay form part of the boundary between the States of Connecticut and Rhode Island. Both states have identified water quality impairments within these waters related to nutrients (insufficient oxygen) and bacteria. Studies of the eutrophication potential of Long Island Sound embayments have identified that the Pawcatuck...

A hierarchical analysis of habitat area, connectivity, and quality on amphibian diversity across spatial scales
