Community Structure and Biodiversity of Intertidal Sandy Beach Macrofauna in Chabahar Bay, Northeast of Oman Gulf, IR Iran
Authors
Abstract:
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 at pre-monsoon while minimum (181 ind/m2) was obtained at monsoon. The highest and lowest value of diversity and richness indices were obtained at pre-monsoon and during monsoon, respectively. Also, multivariate analysis separated monsoon season from pre and post monsoon clearly. Our results show that monsoon can be the most important factor on biodiversity and community structure of macrofauna at Chabahar Bay and intertidal of this bay have not favorable environment for macrofauna development.

Correction: Environmental Control on Fish and Macrocrustacean Spring Community-Structure, on an Intertidal Sandy Beach
The inter-annual variability of the fish and macrocrustacean spring community on an intertidal sandy beach near the Canche estuary (North of France) was studied from 2000 to 2013 based on weekly spring sampling over an 11-year period. Twenty-eight species representing 21 families were collected during the course of the study. The community was dominated by a few abundant species accounting for ...

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...
