Natural disturbances are an important driver of population dynamics. Because it is difficult to observe wildlife during these events, our understanding of the strategies that species use to survive these disturbances is limited. On October 10, 2018, Hurricane Michael made landfall on Florida's northwest coast. Using satellite and acoustic telemetry, we documented movements of 6 individual turtles: one loggerhead sea turtle, one Kemp's ridley sea turtle, three green sea turtles and one diamondback terrapin, in a coastal bay located less than 30 km from hurricane landfall. Post-storm survival was confirmed for all but the Kemp's ridley; the final condition of that individual remains unknown. No obvious movements were observed for the remaining turtles however the loggerhead used a larger home range in the week after the storm. This study highlights the resiliency of turtles in response to extreme weather conditions. However, long-term impacts to these species from habitat changes post-hurricane are unknown.
自然干扰是种群动态的一个重要驱动因素。由于在这些事件中很难观察野生动物，因此我们对物种在这些干扰中生存所使用的策略的理解是有限的。2018 年 10 月 10 日，飓风迈克尔在佛罗里达州西北海岸登陆。使用卫星和声学遥测技术，我们记录了 6 只海龟的活动：一只红海龟、一只坎皮海龟、三只绿海龟和一只玳瑁，它们在距离飓风登陆点不到 30 公里的一个沿海湾。除了坎皮海龟外，所有海龟都在风暴后幸存下来；最后那只海龟的情况仍然未知。然而，其余海龟没有明显的移动，但是红海龟在风暴后的一周内使用了更大的家域。这项研究强调了海龟对极端天气条件的恢复力。然而，飓风后对这些物种的栖息地变化的长期影响尚不清楚。
