Abstract

Abstract Island ecosystems have attracted the attention of scientists since the early days of science because of their formation and biodiversity. Despite their abundant freshwater resources, data on freshwater diversity of Gökçeada are incomplete, especially for macroinvertebrates. This study was conducted in a wide range of freshwater ecosystems on Gökçeada between May 2016 and September 2018. Sampling of macroinvertebrates was performed using a hand net from 34 pre-selected sampling sites on the island. A total of 78 aquatic macroinvertebrate taxa were found, 46 of which are new records for the island. The most common species during the study were Gammarus komareki and Bythinella gokceadaensis with a frequency of 25.93%, followed by Tubifex tubifex, Gammarus sp. and Caenis sp. with a frequency of 22.22%. Endemic and invasive species on the island were assessed according to their presence and frequency values. Based on the results of the current study and previous data, it can be concluded that Gökçeada is characterized by a remarkable species diversity compared to aquatic macroinvertebrates on other Aegean islands.

Gökçeada岛(北爱琴海，土耳其)淡水大型无脊椎动物的生物多样性

岛屿生态系统的形成和生物多样性从科学发展之初就引起了科学家们的关注。尽管其淡水资源丰富，但Gökçeada的淡水多样性数据不完整，特别是大型无脊椎动物。该研究于2016年5月至2018年9月在Gökçeada上的广泛淡水生态系统中进行。从岛上34个预先选定的采样点使用手网对大型无脊椎动物进行了采样。共发现水生大型无脊椎动物类群78个，其中46个为岛上新记录。研究中最常见的种是Gammarus komareki和Bythinella gokceadaensis，频率为25.93%，其次是Tubifex Tubifex, Gammarus sp.和Caenis sp.，频率为22.22%。根据岛上特有物种和入侵物种的存在和频率值进行了评估。根据目前的研究结果和以往的数据，可以得出结论，Gökçeada与其他爱琴海岛屿上的水生大型无脊椎动物相比，具有显著的物种多样性。
