科学家通过卫星追踪发现，加拉帕戈斯群岛的黄形绿海龟打破了同类的远距离迁徙习性，选择在岛屿附近的沿海栖息地活动。1阿尔玛学院的研究团队自2015年起对9只成年海龟（其中7只雄性、2只雌性）进行了追踪，追踪周期最长418天，结果显示没有一只被标记的海龟离开面积为198,000平方公里的加拉帕戈斯海洋保护区。1
研究团队发现，这些海龟的平均活动范围约为1,498平方公里，最远仅距岛屿约25公里。1研究还揭示了这些海龟在季节上的移动模式——岛屿间的迁移仅在4月至10月的较冷时期发生。1项目负责人约翰·W·罗威教授表示："我们预期它们会迁移到西太平洋的远处海滩进行繁殖，但有趣的是，在我们三年的研究中，没有一只被卫星标记的海龟甚至离开加拉帕戈斯海洋保护区。"1这些发现强调了这些海龟对特定岛屿和沿海生境的依赖对其生存的重要意义。1研究成果已发表在《两栖爬行动物科学前沿》期刊上。1
A three-year satellite tracking study has revealed that yellow-bellied sea turtles in the Galápagos Islands exhibit behavior contrary to what scientists anticipated, staying within coastal habitats near their home islands rather than undertaking the long-distance migrations typical of their species.1 Researchers monitored nine adult sea turtles—seven males and two females—beginning in 2015, with some tracking periods extending up to 418 days.1 Notably, none of the tagged turtles left the Galápagos Marine Reserve during the entire study period.1
The findings challenge previous assumptions about the species' migratory patterns. "We expected them to migrate to distant beaches in the western Pacific for breeding, but interestingly, over our three years of research, not a single satellite-tagged sea turtle even left the Galápagos Marine Reserve," said Professor John W. Rowe of Alma College, who led the research team.1 The tracked turtles maintained an average home range of approximately 1,498 square kilometers, with maximum distances of about 25 kilometers from the nearest island.1 Movement between islands occurred only during the cooler months from April to October.1 These findings underscore the critical importance of specific islands and coastal habitats for the survival and persistence of this turtle population.1 The research was published in Frontiers in Amphibian and Reptile Science in 2026.1
