Macrobenthos community structure in coastal waters of Qeshm Island

Abstract

Introduction: The aim of this study was to determine the density, distribution and diversity of the structure of macrobenthic communities in the coastal waters of Qeshm Island.
Materials & Methods: The structure macrobenthos communities in the Coastal waters of the Qeshm Island was studied seasonally in 6 station during 2010. The data analysis using SPSS software version 16 and calculate the diversity in dices of the Primer software version 4.5 was used.
Result: In general, this study of 49 families and 86 genera of macrobenthos were identified. In this study relative abundance Pitar and pronospio genus, equal to 28.44% and 11.46%, respectively. Spearman correlation test showed that the significant correlation between the abundance of macrobentoses and total organic matter. Spatial Cluster Analysis showed that the similarity between the nearest station to station 5 and 6 (45.7%) and 1 and 2 (44.3%), respectively. The result showed that Maximum diversity in station 2 And lowest at Station 6 respectively. Annual change in diversity indices of passenger jetty and coastal parks showed that both areas of moderate pollution (3-1) respectively and the ecological conditions are also in the moderate rank.
Conclusion: Two-way ANOVA that Spatial and temporal of abundance and diversity indices were not significant at between stations or different seasons (P<0.05).
