We examined sequence variation in the mitochondrial cytochrome b gene (1140 bp, n = 73) and control region (842–851 bp, n = 74) in the Eurasian harvest mouse (Micromys minutus (Pallas, 1771)), with samples drawn from across its range, from Western Europe to Japan. Phylogeographic analyses revealed region-specific haplotype groupings combined with overall low levels of inter-regional genetic divergence. Despite the enormous intervening distance, European and East Asian samples showed a net nucleotide divergence of only 0.36%. Based on an evolutionary rate for the cytochrome b gene of 2.4%·(site·lineage·million years)–1, the initial divergence time of these populations is estimated at around 80 000 years before present. Our findings are consistent with available fossil evidence that has recorded repeated cycles of extinction and recolonization of Europe by M. minutus through the Quaternary. The molecular data further suggest that recolonization occurred from refugia in the Central to East Asian region. Japanese haplotypes of M. minutus, with the exception of those from Tsushima Is., show limited nucleotide diversity (0.15%) compared with those found on the adjacent Korean Peninsula. This finding suggests recent colonization of the Japanese Archipelago, probably around the last glacial period, followed by rapid population growth.

Phylogenetic relationships among the East Asian species of the genus Crocidura (Mammalia, Insectivora, Soricidae) were inferred from the partial sequences (402 base pairs) of the mitochondrial cytochrome b gene. Six species of Crocidura and one representative of another insectivoran genus Suncus were examined. In the neighbor joining tree, four distinct lineages were recognized: C. lasiura from northeastern China and Korea, and C. dsinezumi from the main-islands of Japan; C. attenuata from Taiwan; C. watasei from the Amami and Okinawa Groups, and S. murinus from the Miyako Group; and C. suaveolens from Tsushima and Taiwan, and C. sibirica from Central Asia in Russian territory. All these lineages excluding C. lasiura and C. dsinezumi were also recognized by the maximum parsimony analysis. Clustering of C. watasei with S. murinus suggested the non-monophyly of the genus Crocidura as of the present definition. Biogeographical implications of the present results were also discussed.

We sequenced the cytochrome b gene from two little-studied mammal species from the highlands of Southwest China, the long-tailed mole Scaptonyx fusicaudus and the gracile shrew-like mole Uropsilus gracilis. This data was used to examine the phylogenetic relationships among 19 talpid species within the family Talpidae (Mammalia: Eulipotyphla). Cytochrome b gene trees supported a basal placement of shrew-like moles (Uropsilus) within the Talpidae, and suggested that fossorial specializations arose twice during talpid evolution. To assess the evolutionary relationships of moles endemic to this region, we additionally sequenced the 12S rRNA gene and the nuclear recombination-activating gene-1 from eight and ten East Asian taxa, respectively. Analyses of these single and concatenated data sets suggested that East Asian shrew moles diverged prior to the evolution of fossorial Eurasian moles. However, we were unable to determine whether semi-fossorial shrew moles are monophyletic. In contrast, fossorial Eurasian genera (Talpa, Mogera and Euroscaptor) were consistently found to form a monophyletic clade, with Mogera and Euroscaptor representing sister taxa. Furthermore, this fossorial clade grouped with the semi-aquatic Desmana, although with fairly low (35-62%) bootstrap support. Mogera imaizumii was found to be more closely related to M. wogura than to M. tokudae. This implies that the ancestors of these three species entered Japan from the Asian continent in this order via a series of migration events, suggesting that the Japanese Islands have played an important role in preserving mole lineages from ancient to recent times.

Taxonomic analysis has previously revealed that the species of moles that inhabit Japan are characterized by exceptional species richness and a high level of endemism. Here, we focused on the evolutionary history of the four Japanese mole species of the genera <i>Euroscapter</i> and <i>Mogera</i>, examining mitochondrial cytochrome <i>b</i> (cyt <i>b</i>) gene sequences and comparing them with those of continental <i>Mogera wogura</i> (Korean and Russian populations), <i>M. insularis</i> from Taiwan, and <i>Talpa europaea</i> and <i>T. altaica</i> from the western and central Eurasian continent, respectively. Our data support the idea that in a radiation center somewhere on the Eurasian continent, a parental stock evolved to modern mole-like morph and radiated several times intermittently during the course of the evolution, spreading its branches to other peripheral geographic domains at each stage of the radiation. Under this hypothesis, the four lineages of Japanese mole species, <i>E. mizura</i>, <i>M. tokudae</i>, <i>M. imaizumii</i>, and <i>M. wogura</i>, could be explained to have immigrated to Japan in this order. <i>Mogera wogura</i> and <i>M. imaizumii</i> showed substantial amounts of geographic variation and somewhat complicated distributions of the cyt <i>b</i> gene types. These intraspecific variations are likely to be associated with the expansion processes of moles in the Japanese Islands during the Pleistocene glacial ages.<br>

Japanese talpid moles exhibit a remarkable degree of species richness and geographic complexity, and as such, have attracted much research interest by morphologists, cytogeneticists, and molecular phylogeneticists. However, a consensus hypothesis pertaining to the evolutionary history and biogeography of this group remains elusive. Recent phylogenetic studies utilizing nucleotide sequences have provided reasonably consistent branching patterns for Japanese talpids, but have generally suffered from a lack of closely related South-East Asian species for sound biogeographic interpretations. As an initial step in achieving this goal, we constructed phylogenetic trees using publicly accessible mitochondrial and nuclear sequences from seven Japanese taxa, and those of related insular and continental species for which nucleotide data is available. The resultant trees support the view that four lineages (<i>Euroscaptor mizura</i>, <i>Mogera tokuade</i> species group [<i>M. tokudae</i> and <i>M. etigo</i>], <i>M. imaizumii</i>, and <i>M. wogura</i>) migrated separately, and in this order, from the continental Asian mainland to Japan. The close relationship of <i>M. tokudae</i> and <i>M. etigo</i> suggests these lineages diverged recently through a vicariant event between Sado Island and Echigo plain. The origin of the two endemic lineages of Japanese shrew-moles, <i>Urotrichus talpoides </i>and <i>Dymecodon pilirostris</i>, remains ambiguous. Further analyses on intra-species diversity are necessary to fully solve the evolutionary histories of Japanese moles and shrew-moles.<br>

We examined the geographic variation of <i>Tokudaia osimensis</i> through the analysis of mitochondria1 cytochrome <i>b</i> (cyt <i>b</i>) gene sequences and the restriction fragment length polymorphism (RFLP) in the nuclear ribosomal RNA gene (rDNA), using samples collected from Tokuno-shima and Amami-oshima in the Ryukyu Islands. The two populations show intrinsic karyological variation (Tokuno-shima, 2n=45; Amami-oshima, 2n=25). Sequences of the cyt <i>b</i> gene differed considerably between the two island populations. The extent of the sequence divergence among 1,140 bp of the gene was calculated to be 0.088 using the Kimura two parameter method, and was comparable to those between related species of rodents such as within genus <i>Mus</i> or <i>Rattus</i>. The extent of the differentiation in the rDNA-RFLP was also high. Three out of 22 restriction site variants were found to be fixed in the nuclear rDNA arrays of hundreds of copies in either one of the two island populations. These intensive inter-populational differences indicate that the two island populations may have been isolated for a considerable period of evolutionary time, probably several millions of years, despite there having been several opportunities for renewed genetic contact during the Pleistocene ice ages. Our data strongly suggest that the current taxonomic status of the populations of the two islands, Amami-oshima and Tokuno-shima, which regards them conspecific, should be reviewed.

We analyzed a concatenated (8492 bp) nuclear-mitochondrial DNA data set from 44 musteloids (including the first genetic data for Lyncodon patagonicus) with parsimony, maximum likelihood, and Bayesian methods of phylogenetic and biogeographic inference and two Bayesian methods of chronological inference. Here we show that Musteloidea emerged approximately 32.4-30.9 million years ago (MYA) in Asia, shortly after the greenhouse-icehouse global climate shift at the Eocene-Oligocene transition. During their Oligocene radiation, which proceeded wholly or mostly in Asia, musteloids diversified into four primary divisions: the Mephitidae lineage separated first, succeeded by Ailuridae and the divergence of the Procyonidae and Mustelidae lineages. Mustelidae arose approximately 16.1 MYA within the Mid-Miocene Climatic Optimum, and extensively diversified in the Miocene, mostly in Asia. The early offshoots of this radiation largely evolved into badger and marten ecological niches (Taxidiinae, Melinae, Mellivorinae, Guloninae, and Helictidinae), whereas the later divergences have adapted to other niches including those of weasels, polecats, minks, and otters (Mustelinae, Ictonychinae, and Lutrinae). Notably, and contrary to traditional beliefs, the morphological adaptations of badgers, martens, weasels, polecats, and minks each evolved independently more than once within Mustelidae. Ictonychinae (which is most closely related to Lutrinae) arose approximately 9.5-8.9 MYA, most likely in Asia, where it diverged into the Old World Ictonychini (Vormela, Poecilictis, Ictonyx, and Poecilogale) and New World Lyncodontini (Lyncodon and Galictis) lineages. Ictonychini presumably entered Africa during the Messinian Salinity Crisis (at the Miocene-Pliocene transition), which interposed the origins of this clade (approximately 6.5-6.0 MYA) and its African Poecilictis-Ictonyx-Poecilogale subclade (approximately 4.8-4.5 MYA). Lyncodontini originated approximately 2.9-2.6 MYA at the Pliocene-Pleistocene transition in South America, slightly after the emergence of the Panamanian land bridge that provided for the Great American Biotic Interchange. As the genera Martes and Ictonyx (as currently circumscribed) are paraphyletic with respect to the genera Gulo and Poecilogale, respectively, we propose that Pekania and Poecilictis be treated as valid genera and that "Martes" pennanti and "Ictonyx" libyca, respectively, be assigned to these genera.

Blood and tissue samples of 40 individuals including 27 parrot species (15 genera; 3 subfamilies) were collected in Indonesia. Their phylogenetic relationships were inferred from 907 bp of the mitochondrial cytochrome-b gene, using the maximum-parsimony method, the maximum-likelihood method and the neighbor-joining method with Kimura two-parameter distance. The phylogenetic analysis revealed that (1) cockatoos (subfamily Cacatuinae) form a monophyletic sister group to other parrot groups; (2) within the genus Cacatua, C. goffini and C. sanguines form a sister group to a clade containing other congeners; (3) subfamily Psittacinae emerged as paraphyletic, consisting of three clades, with a clade of Psittaculirostris grouping with sub family Loriinae rather than with other Psittacinae; (4) lories and lorikeets (subfamily Loriinae) emerged as monophyletic, with Charmosyna placentis a basal sister group to other Loriinae, which comprised the subclades Lorius; Trichoglossus+Eos; and Chalcopsitta+Pseudeos.
