摘　　要：珊瑚礁体中隐藏着大部分珊瑚礁生物,其中软体动物是重要的组成部分之一,它们对珊瑚礁生物群落结构和功能至关重要。为了解涠洲岛珊瑚礁区隐居软体动物的种类组成,本研究于2017年5月至2020年5月,采用标准化自主珊瑚礁监测装置(Autonomous Reef Monitoring Structures,ARMS)对涠洲岛珊瑚礁区的隐居软体动物进行收集和分析。ARMS被分别放置在涠洲岛西南部、北部和东部海底,3年后取回,从ARMS中分类鉴定出隐居软体动物53种,其中多板纲(Polyplacophora)2科2属2种,腹足纲(Gastropoda)21科26属33种,双壳纲(Bivalvia)11科15属18种;53种隐居软体动物中有18种为空壳,其中腹足纲9科11属15种,双壳纲2科2属3种。优势种为豆荚钳蛤(Isognomon legumen),其次依次为粗糙真蹄螺(Euchelus scaber)、头巾牡蛎(Booneostrea subucula)和布纹蚶(Barbatia decussata)。香农威纳(Shannan Wiener)多样性指数(H′)、马格列夫(Margalef)丰富度指数(d)和皮洛(Pielou)均匀度指数(J′)分别为3.51、9.59和0.99。本研究初步获得了涠洲岛珊瑚礁区隐居软体动物的种类组成和多样性,丰富了该海域的底栖生物数据,可为涠洲岛的珊瑚礁生态监测和保护提供数据来源。Most coral reef organisms are hidden in the structure of coral reefs,among which mollusks are one of the important components,which are crucial to the structure and function of coral reef communities.In order to understand the species composition of cryptic mollusks in coral reef area of the Weizhou Island,this study collected and analyzed the cryptic mollusks in the coral reef area of the Weizhou Island by using the standardized Autonomous Reef Monitoring Structures(ARMS)from May 2017 to May 2020.ARMS was placed in the southwest,north and east of the Weizhou Island,and retrieved after 3 years.53 species of cryptic mollusks were identified from ARMS,in which,2 families,2 genera and 2 species of Polyplacophora,21 families,26 genera and 33 species of Gastropoda,11 families,15 genera and 18 species of Bivalvia.Among the 53 species of cryptic mollusk,18 species were empty shells,in which,9 families,11 genera,15 species of Gastropoda,and 2 families,2 genera,3 species of Bivalvia.The dominant species were Isognomon legumen,followed by Euchelus scaber,Booneostrea subucula,and Barbatia decussata.Shannon Wiener diversity index(H′),Margalef richness index(d)and Pielou evenness index(J′)was 3.51,9.59 and 0.99,respectively.This study preliminarily obtained the species composition and diversity of cryptic mollusks in the coral reef area of the Weizhou Island,enriched the benthic data of the sea area,and provided data sources for the ecological monitoring and protection of coral reefs in the Weizhou Island.
