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.
1992年至1995年期间不定期监测了热带地点(蓬塔德拉洛马，哥伦比亚加勒比地区)的大藻潮间带群落。在较小的空间尺度(平方厘米)上，大藻群落的盖度、分类群和生物量相对稳定。然而，在较大的空间尺度(平方米)上，优势度和组成有一个小而确定的季节性脉冲。在干旱季节，岩石潮间带上的沙粒入侵是一种强烈的干扰，减少了大型藻类的覆盖。年际变化也被发现。La Punta de La Loma似乎受到区域上升流条件的影响。
