摘要:
Abstract.The production rates of intertidal algae at seven study sites in the Saklanha Bay area. South Africa, were measured monthly for 15 months. Algae grew rapidly and formed extensive, permanent mats on shores that were enriched with nutrients from the dissolved guano of seabirds. The most significant correlate of limpet(Patella granulans)growth was the rate of algal production; more rapid limpet growth on nutrient‐rich shores, combined with the effects of predation by African Black OystercatchersHaematopus moquinion limpets, led to differences in the size structures and life‐history patterns of populations of limpets on enriched and unenricheci shores. The rate of primary production affected relationships between intertidal organisms at all trophic levels and influenced patterns of organization within the commun
