Abstract

The present study was conducted with the aim of identification of macrobenthos in the Yekshabe estuary in Persian Gulf. Sampling of macrobenthos was performed from spring 2015 for one year. It was carried out seasonally by the Van Veen Grab (0.04 m2) at four stations, with three replications. The identified macrobenthos belonged to 51 families, 70 genera, 80 species, 4 classes (including Polychaeta, Malacostraca, Bivalvia, Gastropoda) and 5 Phyla. The average total density of macrobenthos was 760±614 per square meter. The most frequently observed classes of macrobenthos belonged to Polychaeta (67.8%), Malacostraca (18.5%), Bivalvia (11.6%) and Gastropoda (1.2%), respectively. According to the results of the Kruskal–Wallis test, there was no significant difference between the macrobenthos classes among the different sampling stations. The highest values of the Shannon-Wiener index of diversity (3.07) and the Margalef's richness index (4.66) were observed in spring, whereas the highest value of the Pielou's evenness index (0.95) was observed in autumn. The values of all indices at station 4 were the highest as compared to those of the others. The results of ANOVA test showed that the mean values of the indices were significantly different (p <0.05) in different seasons, whereas the mean values were not significantly different at stations

大型底栖动物对波斯湾叶沙别河-河口生态状况的指示作用

本研究旨在识别波斯湾耶克沙贝河口的大型底栖动物。从2015年春季开始对大型底栖动物进行为期一年的采样。由Van Veen Grab（0.04 m2）在四个站点进行季节性试验，进行三次重复。已鉴定的大型底栖动物分属4纲51科70属80种4纲5门。大型底栖动物的平均总密度为每平方米760±614只。最常观察到的大型底栖动物类别分别为多壳纲（67.8%）、马六甲纲（18.5%）、双壳纲（11.6%）和腹足纲（1.2%）。根据Kruskal–Wallis检验的结果，不同采样站的大型底栖动物类别之间没有显著差异。Shannon Wiener多样性指数（3.07）和Margalef丰富度指数（4.66）在春季最高，而Pielou均匀度指数（0.95）在秋季最高。与其他监测站相比，4号监测站的所有指数值最高。ANOVA检验结果显示，不同季节的指数平均值有显著差异（p<0.05），而站点的平均值没有显著差异
