Spatiotemporal variation of high-temperature events and its relation to coral bleaching in the Ryukyu Islands, Japan by Sayaka Yasunaka, Haruko Kurihara, Takeshi Doi

“…The central-to-eastern equatorial Pacific displayed a negative sea surface temperature anomaly, and the eastern Indian Ocean did a positive anomaly following high-temperature events near the Ryukyu Islands. These findings indicated that the high-temperature events around the Ryukyu Islands show correlation with La Niña and a negative Indian Ocean Dipole. …”

Evolutionary Relationship between Two Firefly Species, Curtos costipennis and C. okinawanus (Coleoptera, Lampyridae), in the Ryukyu Islands of Japan Revealed by the Mitochondrial and Nuclear DNA Sequences by Masahiko Muraji, Norio Arakaki, Shigeo Tanizaki

“…The phylogenetic relationship, biogeography, and evolutionary history of closely related two firefly species, Curtos costipennis and C. okinawanus, distributed in the Ryukyu Islands of Japan were examined based on nucleotide sequences of mitochondrial (2.2 kb long) and nuclear (1.1-1.2 kb long) DNAs. …”

East Asian Gene flow bridged by northern coastal populations over past 6000 years by Juncen Liu, Yichen Liu, Yongsheng Zhao, Chao Zhu, Tianyi Wang, Wen Zeng, Bo Sun, Fen Wang, Hui Han, Zhenguang Li, Xiaotian Feng, Peng Cao, Fengshi Luan, Feng Liu, Qingyan Dai, Junfeng Guo, Zimeng Wang, Chengmin Wei, Qiaowei Wei, Ruowei Yang, Weihong Hou, Wanjing Ping, Fan Bai, Bo Miao, Wenjun Wang, Melinda A. Yang, Qiaomei Fu

“…We found that ancestry related to ShanDong populations likely explains the mainland East Asian ancestry observed in post-Yayoi populations from the Japanese archipelago, particularly recent populations who lived in the Ryukyu Islands after ~2800 BP. In the ShanDong region, we observed gene flow from populations to the north and south of this region by at least ~7700 BP, and two waves of gene flow associated with the inland Yellow River populations into the ShanDong region during the DaWenKou cultural period (6000-4600 BP) and in the early dynastic period (3500-1500 BP). …”
