Description
Summary:Despite their ecological and social-economic importance, coral reefs are under constant threat and thus require proper management practices. Data on the spatial structure of these ecosystems are essential for good quality conservation projects in such areas. This study aimed to quantitatively analyze the spatial distribution of benthic macroorganisms from the reef environment of Porto de Galinhas Beach, with special focus on its corals and calcified hydroids. Reef flats of the area were surveyed by scuba diving, using 10m line transects. A high cover of macroalgae was verified, averaging 53% of the observations. Zoanthids were the second most representative group (11%). A total of 173 colonies of corals and calcified hydroids were observed and 40% of these colonies were partially or totally bleached.
