“…4). This finding implies that species found in subtropical areas had been affected by late Quaternary environmental fluctuations, as had those in areas of higher latitude (Suzuki et al 2015;Hanazaki et al 2017;Honda et al 2019).…”

“…The cluster exhibited a star-like structure and possessed significant signals of rapid expansion, with a τ value of 6.79 (1140 bp; Table 2). Using an evolutionary rate of 0.047 substitutions/site/myr for Cytb sequences (Honda et al 2019), the expansion time was estimated as 63,000 years BP (CI: 44,000-77,000 years ago), corresponding to the rapid warming period during early MIS 3, following a bottleneck event during the colder period of MIS 4 (e.g., Woltering et al 2011) (Fig. 4).…”

“…Previously, we addressed rapid expansion events seen in local populations of wood mice and voles occurring in the Japanese archipelago and applied biogeographic events as LGM, early MIS 3, and post PGM. Accordingly, we chose the evolutionary rate (μ') as one of the options based on the obtained 0.11, 0.047, or 0.028 substitutions/site/myr, respectively (Honda et al 2019). Data for this study are available in the Dryad Digital Repository: https://doi.org/10.5061/dryad.7pvmcvdqm.…”

“…Population expansion events have been deduced for rodents dwelling in temperate forests (genus Apodemus) (Hanazaki et al 2017). In addition, population expansion events have been inferred for subarctic grassland-dwelling rodents (genus Myodes) (Kohli et al 2015;Honda et al 2019) during the intermediate period 50,000-60,000 years ago, when warmer conditions were beginning during early marine oxygen isotope stage 3 (MIS 3) after a substantially colder period (MIS 4) (e.g., Sawagaki et al 2004;Shang et al 2018). Therefore, we sought to determine whether these critical periods of drastic environmental change during the late Quaternary affected the population dynamics of species in subtropical areas.…”

We addressed the spatiotemporal characteristics of four commensal rodent species occurring in Myanmar in comparison with other areas of the Indo-Malayan region. We examined sequence variations of the mitochondrial cytochrome b gene (Cytb) in the Pacific rat (Rattus exulans), roof rat (Rattus rattus complex, RrC), lesser bandicoot rat (Bandicota bengalensis), and house mouse (Mus musculus) using the recently developed time-dependent evolutionary rates of mtDNA. The Cytb sequences of RrC from Myanmar were shown to belong to RrC Lineage II, and their level of genetic diversity was relatively high compared to those of the other three species. RrC was found to have experienced bottleneck and rapid expansion events at least twice in the late Pleistocene period in Myanmar and a nearby region. Accordingly, paleoclimatic environmental fluctuations were shown to be an important factor affecting rodents in the subtropics of the Indo-Malayan region. Our results show that human activities during the last 10,000 years of the Holocene period affected the population dynamics of the rodent species examined, including introducing them to Myanmar from neighboring countries. Further study of these four commensal rodents in other geographic areas of the Indo-Malayan region would allow us to better understand the factors that drove their evolution and their ecological trends.

This study investigated the relative influences of environmental, spatial, and historical factors, including the island‐specific history of land connectivity, on bat assemblages in the Japanese Archipelago. We collected bat distribution data from 1408 studies and assigned them to Japan's First Standard Grid (approximately 6400 km2). Japanese bat assemblages were analyzed at two scales: the entire Japanese Archipelago comprised 16 islands and exclusively the four main islands. At first, we calculated taxonomic and functional total beta diversity (βtotal) by Jaccard pairwise dissimilarity and then divided this into turnover (βrepl) and richness‐difference (βrich) components. We conducted hierarchical clustering of taxonomic beta diversity to examine the influence of the two representative sea straits, Tsugaru and Tokara, which are considered biogeographical borders. Variation partitioning was conducted to evaluate the relative effects of the three factors on the beta diversity. Clustering revealed that the Tokara Strait bordered the two major clades; however, the Tsugaru Strait did not act as a biogeographical border for bats. In the variation partitioning, shared fraction between spatial and historical factors significantly explained taxonomic and functional βtotal and taxonomic βrepl at the entire archipelago scale, but not at the four main islands scale extending only Tsugaru Strait but not Tokara Strait. Pure environmental factors significantly explained functional βtotal at both scales and taxonomic βtotal only at the four main islands scale. These results suggest that spatial and historical factors are more pronounced in biogeographical borders, primarily structuring assemblage composition at the entire archipelago scale, especially in taxonomic dimension. However, current environmental factors primarily shape the assemblage composition of Japanese bats at the main island scale. The difference in results between the two scales highlights that the primary processes governing assemblages of both dimensions depend on the quality of the dispersal barriers between terrestrial and aquatic barriers for bats.
