Global diversity patterns in sandy beach macrofauna: a biogeographic analysis
Unlike the advances generated on land, the knowledge of global diversity patterns in marine ecosystems is limited to a small number of studies. For sandy beaches, which dominate the world's ocean shores, previous meta-analyses highlighted the role of beach morphodynamics in explaining species richness patterns. Oceanographic variables and historical processes have not been considered, even thou...
متن کاملCommunity Structure and Biodiversity of Intertidal Sandy Beach Macrofauna in Chabahar Bay, Northeast of Oman Gulf, IR Iran
Biodiversity and community structure of macrofauna of the intertidal sandy beach at Chabahar Bay were studied for a period of ten months in 2007. A total of 32 species were observed and identified in this study so that polychaete with 16 species was numerically dominant. The results showed changing densities were influenced by monsoon season so that maximum density (1935.47 ind/m2) was observed...
متن کاملSuccession of macrofauna on macroalgal wrack of an exposed sandy beach: effects of patch size and site.
In this study, we used experimental manipulation of algal wrack to test hypotheses about influences on macrofaunal assemblages inhabiting the upper shore level of different sites along an exposed sandy beach. First, we hypothesized that decomposition of algal wrack depends on wrack patch size and site. With respect to macrofauna, we tested the hypotheses that (1) abundance of colonising individ...
متن کاملThe Influence of Tidal and Rainfall Cycles on Intertidal Nematodes: a Case Study in a Tropical Sandy Beach
The present study describes the nematode assemblage of the bay of Tamandaré (Brazil), a tropical sandy beach, during the low, flood, high and ebb tides of two consecutive tidal cycles in four different months of the year (May, July, September and November). The nematode assemblage was dominated by Metachromadora and Perepsilonema and varied significantly between months and tides. Densities were...
متن کاملGolden opportunities: A horizon scan to expand sandy beach ecology
Robust ecological paradigms and theories should, ideally, hold across several ecosystems. Yet, limited testing of generalities has occurred in some habitats despite these habitats offering unique features to make them good model systems for experiments. We contend this is the case for the ocean-exposed sandy beaches. Beaches have several distinctive traits, including extreme malleability of hab...
