Diurnal activity patterns and habitat use of juvenile Pastinachus ater in a coral reef flat environment

Stingrays are thought to play important ecological roles in coral reef ecosystems. However, little is known about juvenile stingray movement patterns and habitat use in coral reefs. This study used active acoustic telemetry to determine fine-scale movement patterns and habitat use of juvenile cowtail stingrays (Pastinachus ater) in a coral reef flat environment.The dataset consists of an Excel spreadsheet including the active tracks of seven cowtail stingrays (4 males and 3 females). Tracking occurred between April and December 2016. Each individual was tracked over 2 days, generating a total of 14 active tracks ranging from 4.91 to 9 h.Depth and tide height values are in cm; Distance from start, total distance and distance from shore are in m; and Rate of Movement (ROM) in m.min-1.Tracking data were analysed using the adehabitatLT, adehabitatHR and glmmTMB packages in R.

刺魟在珊瑚礁生态系统中被认为发挥着重要的生态功能。然而目前学界对珊瑚礁生境中幼刺魟的运动模式与栖息地利用特征仍知之甚少。本研究采用主动声学遥测（active acoustic telemetry）技术，探究了珊瑚礁坪生境中幼年牛尾刺魟（Pastinachus ater）的细尺度运动模式与栖息地利用特征。本数据集包含一份Excel表格，记录了7尾牛尾刺魟（4雄3雌）的主动追踪轨迹。追踪工作于2016年4月至12月间开展，每尾个体的追踪周期为2天，最终共得到14条追踪轨迹，单条轨迹时长介于4.91至9小时之间。数据集中的水深与潮高单位为厘米（cm）；起始点距离、总移动距离及离岸距离单位为米（m）；移动速率（Rate of Movement, ROM）单位为米·分钟⁻¹（m·min⁻¹）。本研究基于R语言中的adehabitatLT、adehabitatHR与glmmTMB软件包对追踪数据进行了分析。
