“…Taiwan is situated in southeastern Asia and is a component of the west Pacific Island arc. The enormous drop in sea level during the Pleistocene glacials formed land bridges that connected Taiwan, mainland Asia, and the Ryukyu Archipelago and accelerated organism colonization of Taiwan (e.g., weasels [62], freshwater fish [63], and damselfly [64]) and movement from Taiwan (e.g., Ophiorrhiza japonica [65]). Accordingly, all of the Taiwanese skullcaps are morphologically close and might be of single origin [29].…”

Diversification, Biogeographic Pattern, and Demographic History of Taiwanese Scutellaria Species Inferred from Nuclear and Chloroplast DNA

2012

The ragged topography created by orogenesis generates diversified habitats for plants in Taiwan. In addition to colonization from nearby mainland China, high species diversity and endemism of plants is also present in Taiwan. Five of the seven Scutellaria species (Lamiaceae) in Taiwan, for example, are endemic to the island. Hypotheses of multiple sources or in situ radiation have arisen to explain the high endemism of Taiwanese species. In this study, phylogenetic analyses using both nuclear and chloroplast markers revealed the multiple sources of Taiwanese Scutellaria species and confirmed the rapid and recent speciation of endemic species, especially those of the “indica group” composed of S. indica, S. austrotaiwanensis, S. tashiroi, and S. playfairii. The common ancestors of the indica group colonized first in northern Taiwan and dispersed regionally southward and eastward. Climate changes during glacial/interglacial cycles led to gradual colonization and variance events in the ancestors of these species, resulting in the present distribution and genetic differentiation of extant populations. Population decline was also detected in S. indica, which might reflect a bottleneck effect from the glacials. In contrast, the recently speciated endemic members of the indica group have not had enough time to accumulate much genetic variation and are thus genetically insensitive to demographic fluctuations, but the extant lineages were spatially expanded in the coalescent process. This study integrated phylogenetic and population genetic analyses to illustrate the evolutionary history of Taiwanese Scutellaria of high endemism and may be indicative of the diversification mechanism of plants on continental islands.

“…Therefore, these 2 populations are substantially distinct and should be regarded as different subspecies. According to Hosoda et al [6], divergence time of M. sibirica in Taiwan from the continent is estimated to be 0.63Ma (middle Pleistocene). Compared to this, divergence time between the S-Korea and Tsushima populations seems to be more recent [6,11].…”

ABSTRACT. We compared craniodental morphology among 5 populations of the Siberian weasel Mustela sibirica including 2 insular ones (Tsushima and Taiwan). Skulls of the insular individuals tended to be smaller than those of continental ones. Shape differences were also detected, but not so pronounced. Considering these results, the Taiwan population should be regarded as a distinct subspecies M. s. taivana from the mainland ones. The Tsushima population may also possibly be a distinct subspecies from the mainland ones, but more detailed studies using a larger number of specimens are needed for a conclusion. The introduced population in Honshu is also differentiated from the source population. This suggests a high morphological plasticity in M. sibirica. The Siberian weasel Mustela sibirica is one of the most widely distributed species among East Asian species of the Carnivora. Due to its wide distribution and habitat diversity, there should be considerable geographic variations. In fact, several authors have reported geographic variation in the skulls [2,18]. In addition, the fact that many subspecies have been described should reflect their high morphological variability. However, the whole picture of geographic variations has not been clarified, and morphological differences among subspecies have not been well defined. Descriptions of subspecies in many cases have been based on comparisons of a small number of specimens, and statistical analyses have not been conducted. Therefore, re-examinations of subspecies considering variations within each population are needed.The focus of this study is on insular variation, an important characteristic in M. sibirica. In many species of Carnivora, insular populations are often differentiated from mainland ones [9,[12][13][14], and have often been described as distinct subspecies. Two subspecies of M. sibirica from islands (M. s. taivana from Taiwan and M. s. quelpartis from Cheju Island, Korea) have been described [22,23]. Furthermore, the Tsushima population is possibly an independent subspecies [1, 2]. However, comparative morphological studies using these insular and nearby mainland populations have not been done. In this study, the craniodental morphology in insular and mainland populations of M. sibirica, which belong to different (or possibly different) subspecies, was compared. MATERIALS AND METHODS Study specimens:In this study, specimens of M. sibirica from 5 localities (Fig. 1) were compared. It is well known *CorrespondenCe to: Kimura, J.,

The least weasel (Mustela nivalis) is one of the most widely distributed carnivorans. While previous studies have identified distinct western and eastern mitochondrial DNA (mtDNA) lineages of the species in the western Palearctic, their broader distributions across the Palearctic have remained unknown. To address the broad-scale phylogeographical structure, we expanded the sampling to populations in Eastern Europe, the Urals, the Russian Far East, and Japan, and analyzed the mtDNA control region and cytochrome b, the final intron of the zinc finger protein on Y chromosome (ZFY), and the autosomal agouti signaling protein gene (ASIP). The mtDNA data analysis exposed the previous western lineage (Clade I) but poorly supported assemblage extending across Palearctic, whereas the previous eastern lineage (Clade II) was reconfirmed and limited in the south western part of the Palearctic. The ZFY phylogeny showed a distinctive split that corresponding to the mtDNA lineage split, although less phylogeographical structure was seen in the ASIP variation. Our data concur with the previous inference of the Black Sea-Caspian Sea area having an ancestral character. The Urals region harbored high mitochondrial diversity, with an estimated coalescent time of around 100,000 years, suggesting this could have been a cryptic refugium. Based on the coalescent-based demographic reconstructions, the expansion of Clade I across the Palearctic was remarkably rapid, while Clade II was relatively stable for a longer time. It seems that Clade II has maintained a constant population size in the temperate region, and the expansive Clade I represents adaptation to the cold regions.
