TOWARDS AN ECOLOGICALLY MEANINGFUL CLASSIFICATION OF MARINE ALGAL MATRICES
Coral reefs. Ecological implications. Epifauna. Macroalgae. Phase shifts.
Algal matrices have become dominant benthic features with the decline of corals caused by anthropogenic impacts. Here, we propose a new approach for classifying these microhabitats and their potential implications for associated epifauna based on a framework for terrestrial vegetation classification. In total, 75 random algal matrices and associated epifauna samples were collected from five locations on the southern coast of Pernambuco/Brazil. The analysis indicated five clusters distinct on the dominant functional forms of algae, along with a putative sixth category. The associated epifauna presented major differences in composition relative to the clusters. The analytical approach outlined here can provide more effective and ecologically significant descriptions of algal matrices, allowing the of more informative and comparable ecological studies of benthic communities on coral reefs.
