Abstract: (234 Views)
This study investigated the structure and biodiversity indices of bivalves in the intertidal zone along the northern coast of the Persian Gulf at Bushehr port. Sampling was conducted seasonally in summer and winter 2016 across five stations. In rocky areas, 50 × 50 cm quadrats and a metal spatula were used, while sandy beaches were sampled with a corer to a depth of 5 cm. In total, six families and ten bivalve species were identified. The highest relative abundances were recorded for Corbulidae (30%), Psammobiidae (25.5%), Arcidae (18%), and Tellinidae (13.5%). One-way ANOVA indicated no significant differences in mean bivalve abundance among stations or seasons (p > 0.05). During the study, particularly in winter, Corbula sulculosa and Gari maculosa were the most abundant species. Shannon diversity index values differed significantly among stations (p < 0.05). Overall, species richness and diversity of bivalves were higher in winter, likely due to the high summer temperatures in the northern Persian Gulf and more favorable winter conditions. The Shannon index ranged from 1.46 to 2.01 across the study period, indicating that the examined stations were generally of poor to very poor ecological quality.
