Composition, distribution and feeding groups of polychaetes from the coral reefs of Guarajuba beach (Eastern Brazil) were examined to investigate their relationship with the present condition of the reefs. The organisms were randomly sampled from three zones: (1) the landward border of the top of an emergent reef (landward emergent reef -LER); (2) the seaward border of the same reef top (seaward emergent reef-SER); (3) the top of a submerged reef at 5 to 6 m depth (submerged reef-SR). Fifteen replicates of reef blocks (average 680 cm 3 sample size) were collected from each zone, twice a year, making a total number of 90 samples. A total of 1754 individuals comprising 40 species were found. LER samples contained 405 individuals represented by 17 species. Perinereis elenacasoae was the dominant species (58%). SER samples consisted of 1184 specimens, and Eunice wasinensis (73%) was the most abundant of the 30 recorded species. The SR samples contained 165 individuals represented by 22 ...

Sand and mud are the most common bottom sediments surrounding the reefs surveyed in the Abrolhos region. Coarse (gravel) sediments are relatively uncommon. • Previous work reported relatively high levels of siliciclastic-dominated sediments in the Abrolhos region, however high levels were not evident in most samples collected during the current study. The reason for this discrepancy is that bottom samples were collected close to reefs and therefore contained bioclastic material from reef organisms rather than sediment transported from shore. • Muddy sediments were mostly of biogenic origin, probably resulting from bioerosional activities of various boring organisms. • Abrolhos is characterized by a relict coral fauna that apparently has a relatively higher tolerance to muddy conditions than most modern coral faunas.

Coral reefs along the Eastern Brazilian coast extend for a distance of 800 km from 12 degrees to 18 degrees S. They are the largest and the richest reefs of Brazil coasts, and represent the Southernmost coral reefs of the Southwestern Atlantic Ocean. Few reef surveys were performed in the 90's in reef areas of Bahia State, particularly in the Abrolhos reef complex, in the Southernmost side of the state. A monitoring program applying the Atlantic and Gulf Rapid Reef Assessment (AGRRA) protocol was initiated in 2000, in the Abrolhos National Marine Park, after the creation of the South Tropical America (STA) Regional Node of the Global Coral Reef Monitoring Network (GCRMN) by the end of 1999. From that time up to 2005, nine reef surveys were conducted along the coast of the State of Bahia, including 26 reefs, with 95 benthic sites, 280 benthic transects, 2025 quadrats and 3537 stony corals. Eighteen of the 26 investigated reefs were assessed once and eight reefs of Abrolhos were s...
