Formatted abstract
The macroalgal intertidal community at a tropical location (Punta de la Loma, Colombian Caribbean) was monitored at irregular intervals from 1992 to 1995. The highly diverse macroalgal community was relatively invariant in cover, taxa and biomass from small spatial scales (square centimeters). At larger spatial scales (square meters), however, there was a small but definitive seasonal pulse in dominance and composition. Sand intrusions over the rocky intertidal represents a strong disturbance reducing macroalgal cover during the dry season. Interannual variation was also detected. La Punta de la Loma appears to be influenced by the regional upwelling conditions.

La comunidad macroalgal intermareal en una localidad tropical (La Punta de la Loma, Caribe colombiano), fue monitoreado a intervalos irregulares entre 1992 y 1995. La altamente diversa comunidad macroalgal presentó pocos cambios en cobertura, número de taxa y biomasa a la escala espacial de los cuadrantes (centímetros cuadrados). Sin embargo, a la escala espacial del paisaje (metros cuadrados) se detectó un pulso estacional en dominancia y composición, pequeño pero definido. Invasiones parciales de arena en la época seca constituyen fuertes eventos de perturbación que reducen la cobertura macroalgal. También se detectó variación interanual. La Punta de la Loma parece estar sujeta a las condiciones locales de sur gencia.
