Abstract

Abstract: Limpet shells can harbour a high diversity of species. Individuals of four limpet species ( Patella depressa, Patella ulyssiponensis, Patella vulgata and Siphonaria pectinata ) were collected monthly during one year in southern Portugal. Epibiont organisms were identified, counted and the percentage cover of facilitator taxa was also recorded. A total of 86 taxa were identified with abundance reaching 674 epibionts on a single basibiont shell. P. ulyssiponensis showed the highest epibiont species diversity and richness while P. depressa and P. vulgata showed similar diversity and richness. P. depressa had a more even epibiotic community mainly due to higher densities of Chthamalus sp. Overall, basibiont species was the key factor determining the epibiotic community, followed by month/season and erect algae. The presence of erect algae potentiated the epibionts diversity on limpet shells, whereas the occurrence of barnacles tended to decrease it and the presence of crustose algae had no significant effect on epibionts diversity. These findings shed further light on the biological and ecological complex relationships among keystone species inhabiting intertidal rocky shores. Graphical abstract: Image 1 Highlights: Limpet shells can carry a high diversity and huge number of epibiont taxa. The type of facilitator species influenced epibionts richness and abundance. The presence of erect algae on limpet shells promoted epibionts attachment. Epibionts diversity and abundance is directly related to limpet shell size.
