Abstract

Seagrasses are essential in coastal ecosystems by providing important ecological benefits, including improved water quality, support for complex food webs, and stabilization of sediments which can reduce shoreline erosion. Increased nutrient concentrations can cause seagrass decline through light reduction caused by the overgrowth of epiphytes, macroalgae, or phytoplankton. Previous research has shown significant epiphyte biomass, nitrogen fixation and diazotroph abundances associated with seagrasses. Phytoplankton contain unique combinations of chlorophyll compounds. Chlorophyll analysis can provide biomass and be used to estimate general phyla information based on presence and abundance of certain chlorophyll compounds. This study will examine biomass, abundance and community composition of epiphytes associated with two species of seagrasses, Thalassia testudinum and Halodule wrightii.
