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

岛屿生态系统由于其形成和生物多样性，自科学早期以来就引起了科学家的关注。尽管淡水资源丰富，但关于 Gökçeada 淡水多样性的数据并不完整，尤其是大型无脊椎动物。这项研究于 2016 年 5 月至 2018 年 9 月期间在 Gökçeada 的广泛淡水生态系统中进行。大型无脊椎动物的采样是使用岛上 34 个预先选择的采样点的手网进行的。共发现水生大型无脊椎动物类群78个，其中46个为全岛新记录。研究期间最常见的物种是 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%。根据其存在和频率值评估岛上的地方性和入侵物种。根据目前的研究结果和之前的数据，可以得出结论，与爱琴海其他岛屿上的水生大型无脊椎动物相比，Gökçeada 具有显着的物种多样性特征。
