Abstract：
Determining the genetic diversity and source rookeries of sea turtles collected from feeding grounds can facilitate effective conservation initiatives. To ascertain the genetic composition and source rookery, we examined a partial sequence of the mitochondrial control region (CR, 796 bp) of 40 green turtles (Chelonia mydas) collected from feeding grounds around the Korean Peninsula between 2014 and 2022. We conducted genetic and mixed-stock analyses (MSA) and identified 10 CR haplotypes previously reported in Japanese populations. In the haplotype network, six, three, and one haplotype(s) grouped with the Japan, Indo-Pacific, and Central South Pacific clades, respectively. The primary rookeries of the green turtles were two distantly remote sites, Ogasawara (OGA) and Central Ryukyu Island (CRI), approximately 1,300 km apart from each other. Comparing three parameters (season, maturity, and specific feeding ground), we noted that OGA was mainly associated with summer and the Jeju Sea, whereas CRI was with fall and the East (Japan) Sea ground. The maturity did not show a distinct pattern. Our results indicate that green turtles in the feeding grounds around the Korean Peninsula originate mainly from the Japan MU and have genetic origins in the Japan, Indo-Pacific, and Central South Pacific clades. Our results provide crucial insights into rookeries and MUs, which are the focus of conservation efforts of the Republic of Korea and potential parties to collaborate for green turtle conservation.
摘要：
确定从饲养场收集的海龟的遗传多样性和来源群可以促进有效的保护举措。为了确定遗传组成和来源，我们检查了线粒体控制区的部分序列(CR，796bp）的40只绿海龟（Cheloniamydas）在2014年至2022年之间从朝鲜半岛周围的饲养场收集。我们进行了遗传和混合库存分析（MSA），并确定了先前在日本人群中报道的10种CR单倍型。在单倍型网络中，六,三,和一个与日本分组的单倍型，印度-太平洋,和中南太平洋进化枝，分别。绿海龟的主要栖息地是两个遥远的偏远地点，小gas原（OGA）和琉球岛中部（CRI），彼此相距约1300公里。比较三个参数(季节，成熟，和特定的馈电地面)，我们注意到OGA主要与夏季和济州海有关，而CRI与秋天和东(日本)海地面有关。成熟度没有显示出明显的模式。我们的结果表明，朝鲜半岛周围饲养场的绿海龟主要来自日本MU，并且在日本具有遗传起源，印度-太平洋,和中南太平洋进化枝。我们的结果提供了对菜鸟和MU的重要见解，这是大韩民国和潜在各方合作保护绿海龟的工作重点。
