Data from the Integrated Tracking of Aquatic Animals in the Gulf of Mexico (iTAG) network, and sister networks, were used to evaluate fish movements in the Florida Keys—an extensive reef fish ecosystem just north of Cuba connecting the Atlantic Ocean and Gulf of Mexico. We analysed ~2 million detections for 23 species, ranging from reef fish such as Nassau grouper (Epinephelus striatus, Serranidae) to migratory apex predators such as white sharks (Carcharodon carcharias, Lamnidae). To facilitate comparisons across species, we used an eco-evolutionary movement strategy framework that identified measurable movement traits and their proximate and ultimate drivers. Detectability was species-specific and quantified with a detection potential index. Life stages detected in the study area varied by species and residency varied with life stage. Four annual movement types were identified as follows: high site-fidelity residents, range residents, seasonal migrants and general migrants. The endangered smalltooth sawfish (Pristis pectinata, Pristidae), a seasonal migrant, exhibited the greatest within-ecosystem connectivity. Site attachment, stopover and deep-water migration behaviours differed between individuals, species and annual movement types. All apex predators were migratory. General migrants were significantly larger than fish in the other movement types, a life-history and movement trait combination that is common but not exclusive, as many small pelagics also migrate. Most teleosts exhibited movements associated with spawning. As concerns grow over habitat and biodiversity loss, multispecies movescapes, such as presented here, are expected to play an increasingly important role in informing ecosystem-based and non-extractive fisheries management strategies.

海洋鱼类的移动景观和生态进化运动策略：评估连接热点

来自墨西哥湾水生动物综合追踪 (iTAG) 网络和姊妹网络的数据被用于评估佛罗里达群岛的鱼类运动——佛罗里达群岛是古巴北部连接大西洋和墨西哥湾的广泛珊瑚礁鱼类生态系统. 我们分析了 23 种物种的约 200 万次检测，范围从拿骚石斑鱼（Epinephelus striatus，Serranidae）等珊瑚鱼到大白鲨（Carcharodon carcharias）等迁徙性顶级掠食者, 虱科）。为了促进跨物种的比较，我们使用了一个生态进化运动策略框架，该框架确定了可测量的运动特征及其最接近和最终的驱动因素。可检测性是物种特异性的，并用检测潜力指数进行量化。在研究区检测到的生命阶段因物种而异，居住地因生命阶段而异。四种年度移动类型被确定如下：高现场保真居民、范围居民、季节性移民和一般移民。濒临灭绝的小齿锯鳐（Pristis pectinata, Pristidae) 是季节性迁徙者，表现出最大的生态系统内连通性。站点附着、中途停留和深水迁徙行为因个体、物种和年度运动类型而异。所有的顶级掠食者都是迁徙的。在其他运动类型中，一般迁徙者明显大于鱼类，生活史和运动特征组合很常见，但并非唯一，因为许多小型中上层鱼类也迁徙。大多数硬骨鱼表现出与产卵相关的运动。随着人们对栖息地和生物多样性丧失的担忧日益加剧，这里介绍的多物种移动景观预计将在为基于生态系统和非采掘性渔业管理战略提供信息方面发挥越来越重要的作用。
