The Divergence History of Two Japanese <i>Torreya</i> Taxa (Taxaceae): Implications for Species Diversification in the Japanese Archipelago by Qian Ou, Xin Huang, Dingguo Pan, Shulan Wang, Yuting Huang, Sisi Lu, Yujin Wang, Yixuan Kou

“…These results demonstrate that vicariant allopatric speciation due to sea-level fluctuations may be a common mode of speciation in the Japanese archipelago. This finding provides insights into the understanding of species diversification in the Japanese Archipelago and even East Asian flora under climatic oscillations during the Quaternary.…”

Phylogeography and genetic relationship within Erebia neriene (Böber, 1890) in eastern Asia inferred from mitochondrial DNA sequences (Lepidoptera: Nymphalidae) by Hisato Nagaoka, Xiaoshuan Bai, Dmitry Goshko, Batzorig Baljinnyam, Toshiaki Yamamoto, Kaneaki Edo, Shigeru Kitanishi

“… Little is known about the genetic relationships within Erebia neriene (Böber, 1890) complexes inhabiting areas outside the Japanese Archipelago. In this study, we investigated genetic variations in E. neriene individuals collected from eastern Asia using mitochondrial sequences to reveal the phylogeny and genetic relationships among E. neriene complexes inhabiting areas outside the Japanese Archipelago. …”

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. …”

Model selection for the sound speed perturbation of GNSS-A using the widely applicable Bayesian information criterion (WBIC) by Shun-ichi Watanabe, Tadashi Ishikawa, Yuto Nakamura, Yusuke Yokota

“…Applying the WBIC-based model selection method to the actual data obtained at the seafloor GNSS-A sites along the Japanese archipelago by the Japan Coast Guard, we found that a simpler model, where the perturbation field is characterized by a uniformly inclined layer is more preferable than models with more degrees of freedom, especially in regions, where the Kuroshio current is strong. …”

Unveiling the vertical ionospheric responses following the 2024 Noto Peninsula Earthquake with an ultra-dense GNSS network by Weizheng Fu, Yuichi Otsuka, Nicholas Ssessanga, Atsuki Shinbori, Takuya Sori, Michi Nishioka, Septi Perwitasari

“…Abstract This paper leverages total electron content (TEC) perturbations obtained from an ultra-dense Global Navigation Satellite System (GNSS) receiver network across the Japanese archipelago to reconstruct the three-dimensional (3-D) structures of ionospheric responses following the 2024 Noto Peninsula Earthquake (Mw7.5). …”

Curiosités géographiques et missions jésuites en Asie du Sud-est dans la première moitié du XVIIe siècle : La Descripsão do Reyno dos Laos, e dos circumvizinhos a ella by Dejanirah Couto

“…This one tried to establish a mission in Laos in order to open a “missionary road” east of Tonkin, heading to the Chinese border, far from the Middle Kingdom coast and the Japanese archipelago, where a succession of political, religious and military events created serious problems to the Society of Jesus at the beginning of the 17th century, and forced it to rethink the strategies of setting up in South-East Asia. …”

Performance Analysis of a Strong Constraint 4DVar and 4DEnVar on Regional Ionosphere Imaging by Nicholas Ssessanga, Wojciech Jacek Miloch, Lasse Boy Novock Clausen, Daria Kotova

“…Preliminary assimilation is performed only with ubiquitous Global Navigation Satellite System observables from ground‐based receivers, with a focus on moderately stable mid‐latitudes, specifically the Japanese archipelago and neighboring areas. Using a simulation analysis, we find that under model space localization, 30 member Ensembles are sufficient for regional SC4DEnVar. …”
