“…Our principal component analysis and multidimensional ordination approach revealed that space influenced the distribution of macroalgae in the Itacimirim reef, with the number of taxa decreasing in regions with less hydrodynamics (FR D 24, PR D 21, and TP D 18). This finding agrees with data presented in studies carried out on different beaches along the coast of Bahia, revealing that large numbers of taxa occur in the reef front, where the energy of the waves is greater, and that less taxa occur as hydrodynamics decreases, for instance in tide pools (Lucio and Nunes, 2002;Lyra et al, 2007;Nunes and Guimarães, 2010). The high taxonomic richness identified and the differences in species composition between habitats reflected the environmental heterogeneity of the Itacimirim reef.…”

This study aimed to inventory the species of marine macroalgae and analyze the distribution and biomass patterns of their communities along a short coastal reef gradient in northeastern Brazil. Samples were collected using the technique of random squares, distributed in the three habitats: reef front region (FR), tide pools (TP), and reef plateau (RP). These three make up the reef gradient from the sea to the beach. A total of 56 taxa were identified, with Ochrophyta and Rhodophyta standing out as the phyla with the greater taxonomic richness, and the largest biomass represented by the species Sargassum vulgare (30 % of total biomass) and (16 %). The key emergening patterns along the reef gradient were the occurrence of groups of exclusive taxa in each habitat, and significant variation in biomass, greater in the TP (166.1 g m-2) and lower in the RP (70.5 g m-2). Despite being an environment under marked anthropogenic influence (i.e., tourism and development), we observed a high diversity of species, with a distribution pattern that reflects a high environmental heterogeneity and substantial ecological integrity.
