海洋动物栖息地连接性包括栖息地之间的历史联系，而迁徙连接性评估海洋动物的扩散或迁徙路线对于理解扩散和/或迁徙及其对遗传种群结构形成的影响是重要的。海龟的迁徙性质和长距离移动的报告，而纳塔尔philopatry已被建议在一个相对狭窄的地理范围内的rookeries之间的遗传分化。因此，我们假设，当代长距离的运动有一个有限的影响，在新的rookeries殖民。本研究比较了东南亚绿色海龟（Chelonia mydas）的产卵场之间以及产卵场与觅食地之间的遗传关系。新近测定了来自11个繁殖地的333只海龟的线粒体控制区序列，并与先前报道的印度-太平洋繁殖地相结合，表明托雷斯海峡和西里伯斯海（即菲律宾-苏拉威西）存在遗传屏障。另一方面，对从7个觅食地点新收集的107只海龟进行的分析和混合种群分析表明，当代运动跨越了这一历史遗传障碍，从西巴丹岛的栖息地到西里伯斯海的觅食地（即西巴丹岛和敦萨卡兰海洋公园）。隔离的距离普遍支持的rookeries之间的关系，和高迁移连接并没有导致较低的遗传距离rookeries比从地理距离预测。东南亚绿色海龟的栖息地连接性和迁移连接性之间的差异可能是由于长距离移动后迁移到纳塔尔地。
Integration of the rookery connectivity, which includes historical connections among rookeries, and migratory connectivity assessing dispersal or migratory routes of marine animals are important for understanding dispersal and/or migration and its effect on the formation of genetic population structure. The migratory nature and long-distance movement of sea turtles have been reported, while natal philopatry has been suggested by genetic differentiation among rookeries within a relatively narrow geographic scale. Therefore, we hypothesize that contemporary long-distance movement has a limited effect on colonization in new rookeries. This study compared the genetic relationships among rookeries and between the rookeries and foraging grounds of green turtles (Chelonia mydas) in Southeast Asia. Mitochondrial control region sequences of 333 turtles from 11 rookeries were newly determined, and combination with previously reported Indo-Pacific rookeries indicated the presence of a genetic barrier in the Torres Strait and Celebes Sea (i.e. Philippines–Sulawesi). On the other hand, an analysis of newly collected 107 turtles from seven foraging sites and mixed stock analyses indicated contemporary movement across this historical genetic barrier, from Micronesian rookeries to foraging grounds in the Celebes Sea (i.e. Sipadan Island and Tun Sakaran Marine Park). Isolation by distance was generally supported for relationships among rookeries, and the high migratory connectivity did not result in a lower genetic distance between rookeries than predicted from geographic distance. Differences between rookery connectivity and migratory connectivity in green turtles in Southeast Asia are likely due to migration to natal regions after long-distance movement.
