摘要:
利用2022年12月、2023年2月和5月在庙岛群岛10个岛屿的砂质潮间带采集的大型底栖动物样品, 对其物种组成、优势种、数量分布、多样性以及群落结构特点进行了研究。3个季节潮间带定性和定量调查共采集到大型底栖动物118种, 定量调查物种数春季(57种)>秋季(45种)>冬季(39种), 软体动物和甲壳动物为主要类群。庙岛群岛潮间带以弱固着型和游走型底栖动物占优势, 3个季节调查共发现5种优势种: 潮间海钩虾(Pontogeneia littorea)、短滨螺(Littorina brevicula)、葛氏囊须虫(Pharyngocirrus gabriellae)、单齿螺(Monodonta labio)和锈凹螺(Chlorostoma rustica)。Kruskal-Wallis检验结果显示,丰度和生物量的季节间和岛屿间差异均不显著。双因素方差分析结果显示, H′季节间差异和站位间差异均显著, J′只季节间差异显著。南部岛屿多样性指数较高, 而丰度和生物量的空间分布无明显规律。聚类和非度量多维标度排序(NMDS)分析表明, 10个岛屿潮间带群落结构的相似性较低, 这可能是庙岛群岛诸岛自然环境差异大, 受人类活动影响程度不同所致。

Abstract:
Species composition, dominant species, quantitative distribution, diversity, and community structure of the macrozoobenthic samples collected from the sandy intertidal zones of the 10 islands of Miaodao Archipelago collected in December 2022 (autumn), February 2023 (winter), and May 2023 (spring) were studied. A total of 118 macrozoobenthic species were collected by qualitative and quantitative surveys during the three seasons, with the highest number in spring (57), followed by autumn (45) and winter (39). Mollusks and crustaceans were the main groups. The Miaodao Archipelago intertidal zones were dominated by weakly attached and mobile macrozoobenthos. The five predominant species identified included Pontogeneia littorea, Littorina brevicula, Pharyngocirrus gabriellae, Monodonta labio, and Chlorostoma rustica. The Kruskal-Wallis test indicated no considerable differences in abundance and biomass among seasons and islands. A two-way ANOVA showed that both seasonal and station differences were significant in H', while only seasonal differences were significant in J'. The diversity indices of the southern islands were higher; however, the spatial distribution of abundance and biomass revealed no clear pattern. Cluster analysis and nonmetric multidimensional scaling (NMDS) analysis indicated that the similarity of the community structures of the intertidal zones among the 10 islands was low, which may be attributed to the large environmental differences and varying degrees of human impact on the islands.
Key words:  Island intertidal zones  Macrozoobenthos  Biodiversity  Community structure
