The Ecological Role of Rhizophytic Green Algae in Soft-bottom Habitats

TL;DRAbstract

Rhizophytic algae are large, abundant primary producers throughout tropical and subtropical areas worldwide where they grow as an understory in seagrass beds, as well as form mixed or monospecific beds of exclusively rhizophytic algal species. In this dissertation, "rhizophytic algae" refers to coenocytic green algae (Chlorophyta) in the order Bryopsidales that use a net of rhizoids to anchor in unconsolidated sediments. In the development of seagrass beds, rhizophytic algae colonize bare patches and are thought to facilitate seagrass colonization by stabilizing sediments and providing organic matter. However, despite their prominence little is known about many aspects of the ecology of rhizophytic algae.\nDetailed information on the abundance and biomass of rhizophytic algae at the species level is scarce and the belowground components are seldom quantified. Moreover, rhizophytic algal communities located along the central west coast of Florida have received very little study. At thre
