| الوصف: | Wrack deposits are a common feature of sandy beaches worldwide. Despite their relevance, the habitat features of wrack debris and their potential influence on the distribution of upper shore arthropods remain poorly understood. In this study, the distribution of supralittoral arthropods was analysed by sampling areas covered and not covered by wrack on two tidal levels during winter and summer from two sandy beaches of south-western Spain. Despite the differences between beaches and seasons, density, species richness and diversity were significantly higher in wrack patches than in bare sand. Moreover, community structure and composition varied between both microhabitats due to the influence of wrack deposits on the habitat selection by arthropod species. Food availability combined with temperature or moisture mostly explained the distribution pattern of assemblages. Moreover, these habitat features varied between wrack bands, the lower band being fresher and wetter than upper band. The density of the main species inhabiting wrack was correlated mainly with moisture. The present study provides evidences about the role of algal wrack structuring diversity and composition of supralittoral arthropods stressing the importance of the habitat heterogeneity to maintain abundant and diverse communities on exposed sandy beaches. |
