The paper reports on a study of the dynamics of fouling communities and the distribution of wood-boring organisms along the coast of Rio de Janeiro, Brazil, which was motivated by the great number of wooden structures usually employed in marinas, wharves, fishing and pleasure crafts, and shipyards. Experiments were independently carried out in four areas which are described in this study. The first one took place at two stations, Portogallo and Piraquara, in Ilha Grande Bay. The second one took place in the Tijuca Lagoon; there, five stations were selected according to a decreasing salinity gradient. At Itajuru Inlet, the third experiment was conducted, using three stations chosen according to an increasing salinity gradient. In Guanabara Bay, two experiments were carried out. The wood-boring organisms were collected using 10 pine-wood sheets (Araucaria angustifolia) of 10 × 10 × 0.08 cm each. Study methods and results are discussed.
