Master's Theses, Dissertations, Graduate Research and Major Papers Overview
Anthropogenic eutrophication of coastal estuaries impacts these vital ecosystems by increasing primary production, hypoxic conditions, pathogen concentration, and greenhouse gas emissions, all of which are leading to the degradation of shorelines, disease transmission, and hypoxia-related fish kills. Narragansett Bay is a prominent feature of Rhode Island, making up over 500 km of coastline and acting as a watershed for over 2,000 square meters of land in both Massachusetts and Rhode Island. This estuary is important to both the economy of the state of Rhode Island and its fringing ecosystems are necessary for a healthy shoreline. The beaches of Narragansett Bay …

Investigating The Leaf Cuticle Of The Moss Physcomitrella Patens, Eric John Ricci
Master's Theses, Dissertations, Graduate Research and Major Papers Overview
To minimize water loss, the aerial parts of vascular land plants are covered with a hydrophobic layer called a cuticle. The cuticle typically consists of two major components: cutin and waxes. In contrast to vascular plants, research reports indicate that some primitive nonvascular plants, such as mosses, lack a cuticle. This study attempts to reconcile contradictory literature reports about the presence of a waxy cuticle on the leaves of the moss Physcomitrella patens.
Histochemical staining was utilized to investigate the presence of a cuticle on Physcomitrella leaves. Experiments employing dyes that stain hydrophobic substances were generally consistent with the …
