Emergence trap sampling of gnathiid isopods at Lizard Island, GBR, Australia from 2016-2018

This dataset contains abundance data for Gnathiid isopods, as well as collection metadata. These data were collected as part of a long-term monitoring study of fish-parasitic gnathiid isopods on shallow patch reefs at Lizard Island, Great Barrier Reef, Australia. The data cover the period from 2000 to 2018. Gnathiid isopods, which spend most of their life free-living, were collected using 1-meter square by 1-meter high pyramid-shaped emergence traps placed randomly on the substrate. The total soak time for the traps was approximately 24 hours, divided into day vs night periods. Some of the patch reefs had cleaner fish, which are known predators of gnathiid isopods, removed over the course of the study (removal) while for others, cleaner fish remained (control).

本数据集包含颚虱科等足类（Gnathiid isopods）的丰度数据及其采集元数据。该数据集源自澳大利亚大堡礁蜥蜴岛浅海斑块礁上的鱼类寄生颚虱科等足类长期监测研究，采样时段为2000年至2018年。颚虱科等足类的一生多数时段营自由生活，研究采用随机布设于底质上的1米见方、高1米的金字塔形出土诱捕器进行采集。诱捕器总采样时长约为24小时，分为日间与夜间两个采样阶段。研究期间，部分斑块礁移除了被证实为颚虱科等足类天敌的清洁鱼（移除组），其余斑块礁则保留清洁鱼（对照组）。
