This study modeled the succession populations of two barnacle species, Tetraclita stalactifera (Lamarck, 1818) and Chthamalus bisinuatus (Pilsbry, 1916), and a bivalve, Brachidontes solisianus (d'Orbigny, 1846), on a sandstone reef at Piedade Beach, Pernambuco State, Brazil. The different stages of the life cycles of these invertebrates are represented by adult and immature forms in this model and are simulated as numbers of individuals per 100cm2. Recruitment rates are represented as forcing functions based on field recruitment experiments with time-steps of 1day. In addition to intraspecific competition, the model takes into account interspecific competition based on reciprocal effects and carrying capacities. Field data from field succession experiments were used to calibrate the model. Recruitment and succession data were collected from random 10×10-cm plots within a 1-m transect on a Brachidontes bed from April to December 2007. Correlation coefficients between field data and simulation results were statistically significant for both populations; sensitivity analysis showed that increases and decreases in invertebrate population densities were always smaller than 10% compared to baseline model values. Patch closure by mussels population growth was one of the main succession processes observed during the rainy season. However, barnacles were the dominant species at the end of both field and simulation succession experiments, with an average density of close to 100 individuals per 100cm2. Cirripedia individuals may inhibit bivalve re-colonization by settling over shells and more efficiently occupying free space in addition to having higher recruitment rates than bivalves during the dry season.
