Abstract This paper analyzes the phylogeographical patterns of amphibian and reptile lineages distributed in Ryukyu islands south Tokara Gap on basis relevant distributional data phylogenetic hypotheses hitherto published. Results indicate numerical dominance highly relict central Ryukyus, occurences a few more or less Miyako Group as well. On other hand, most species subspecies endemic to Yaeyama Groups are considered be direct consequences vicariance with adjacent regions. Three major...
Abstract The 17,191-bp mitochondrial DNA (mtDNA) of a Japanese colubrid snake, akamata (Dinodon semicarinatus), was cloned and sequenced. snake mtDNA has some peculiar features that were found in our previous study using polymerase chain reaction: duplicate control regions have completely identical sequences over 1 kbp, translocation tRNALeu(UUR) gene, shortened TψC arm for most tRNA genes, pseudogene tRNAPro. Phylogenetic analysis amino acid protein genes suggested an unusually high rate...
Mitochondrial DNA (mtDNA) regions corresponding to two major tRNA gene clusters were amplified and sequenced for the Japanese pit viper, himehabu. In one of these clusters, which in most vertebrates characterized date contains three tightly connected genes tRNA(Ile), tRNA(Gln), tRNA(Met), a sequence approximately 1.3 kb was found be inserted between tRNA(Ile) tRNA(Gln). The insert consists control-region-like possessing some conserved blocks, short flanking sequences may folded into...
Identifying and dating historical biological events is a fundamental goal of evolutionary biology, recent analytical advances permit the modeling factors known to affect both accuracy precision molecular date estimates. As use multilocus data sets becomes increasingly routine, it more important evaluate potentially confounding effects rate heterogeneity within (e.g., codon positions) among loci when estimating divergence times. Here, using Plestiodon lizards as test case, we examine...
Comparative genome analysis of non-avian reptiles and amphibians provides important clues about the process evolution in tetrapods. However, there is still only limited information available on structures these organisms. Consequently, protokaryotypes amniotes tetrapods evolutionary processes microchromosomes remain poorly understood. We constructed chromosome maps functional genes for Chinese soft-shelled turtle (Pelodiscus sinensis), Siamese crocodile (Crocodylus siamensis), Western clawed...
<h3>OBJECTIVE</h3> To evaluate secular trends in the incidence and prevalence of rheumatoid arthritis (RA) Japan. <h3>METHODS</h3> The RA were determined a longitudinal population based study Kamitonda district, Wakayama, Japan, from 1965 to 1996. <h3>RESULTS</h3> In area consisting about 3000 inhabitants, 16 incident cases, satisfying definite by Rome criteria detected during period. age sex adjusted both men women combined significantly decreased (p<0.025 p<0.01, respectively). all...
Recent progress of chicken genome projects has revealed that bird ZW and mammalian XY sex chromosomes were derived from different autosomal pairs the common ancestor; however, evolutionary relationship between reptilian is still unclear. The Chinese soft-shelled turtle <i>(Pelodiscus sinensis)</i> exhibits genetic determination, but no distinguishable (heteromorphic) have been identified. In order to investigate this further, we performed molecular cytogenetic analyses species,...
A new scincid lizard, Plestiodon takarai sp. nov., is described from the Senkaku Group, Ryukyu Archipelago, Japan. The lizards in this island group have previously been identified as P. elegans because they all exhibit a patch of enlarged and irregularly arranged scales on posterior surface their femurs. However, detailed molecular analyses revealed that population, although closely related to other species latiscutatus group, substantially diverged recognized species. Furthermore,...
A molecular phylogenetic survey was conducted using mtDNA sequences of 12S and 16S rRNA, cyt-b genes to examine taxonomic relationships among populations the Pan-Oriental microhylid, Microhyla ornata, from India, Bangladesh, Thailand, Laos, China, Taiwan, Ryukyu Archipelago Japan. Two discrete clades are recognized within this species, one consisting India other encompassing remaining populations. In latter clade, clearly split rest (populations Taiwan continent) with considerable degrees...
The Hokou gecko (Gekko hokouensis: Gekkonidae, Gekkota, Squamata) has the chromosome number 2n = 38, with no microchromosomes. For molecular cytogenetic characterization of gekkotan karyotype, we constructed a map for G. hokouensis, which retains ancestral karyotype 86 functional genes, and compared it maps four Toxicofera species that have many microchromosomes (Elaphe quadrivirgata, Varanus salvator macromaculatus, Leiolepis reevesii rubritaeniata, Anolis carolinensis) lacertid (Lacerta...

Blue-tailed skinks (genus Plestiodon) are a common component of the terrestrial herpetofauna throughout their range in eastern Eurasia and North Middle America. Plestiodon species also frequent subjects ecological evolutionary research, yet comprehensive, well-supported phylogenetic framework does not exist for this genus. We construct comprehensive molecular phylogeny using Bayesian analyses nine-locus data set comprising 8308 base pairs DNA, sampled from 38 43 evaluate potential gene...
The Ryukyu Archipelago accommodates 52 native species/subspecies (26 genera belonging to ten families) of terrestrial reptiles and 22 (ten six amphibians. This paper reviews the geographic similarity diversity patterns current herpetofauna Ryukyus adjacent regions, discusses factors influencing formation it in this archipelago. Cluster analyses indices for both amphibians indicate that is strongly influenced by geohistory archipelago involving long isolation especially its north-central part...
Phylogenetic analyses were carried out for representatives of all eublepharid genera and a few other gekkonoid taxa using sequence data 879 base pairs mitochondrial 12S 16S ribosomal RNA genes. Neighbor-joining (NJ) distance analysis the suggested independent great divergences Coleonyx Aeluroscalabotes, monophyly remainder within Eublepharidae (bootstrap proportion [BP]=76%). Of latter, two African genera, Hemitheconyx Holodactylus, almost certainly monophyletic altogether (BP=99%), whereas...
To investigate geographic genetic structures and taxonomic relationships among isolated populations of Buergeria japonica, occurring very widely in various habitats the Ryukyu Archipelago Taiwan, we conducted phylogenetic demographic analyses individuals from localities, representing their entire distributional ranges. japonica is genetically greatly differentiated comprises three major clades (the Southern Taiwan [ST] clade, Northern + [NT/SR] Central [CR/NR] clade), each which seems to...
Abstract Niche breadth and position can influence diversification among closely related species or populations, yet limited empirical data exist concerning the predictability of outcomes. We explored effects these factors on evolution Emoia atrocostata group, an insular radiation lizards in western Pacific Ocean Indo-Australasia composed both endemic widespread that differ niche occupancy. used molecular phylogeographical diffusion models to estimate timing patterns range expansion,...
Horizontal transfer (HT) of genes between multicellular animals, once thought to be extremely rare, is being more commonly detected, but its global geographic trend and mechanism have not been investigated. We discovered a unique HT pattern Bovine-B (BovB) LINE retrotransposons in vertebrates, with bizarre direction from predators (snakes) their prey (frogs). At least 54 instances BovB were which we estimate occurred across time 85 1.3 Ma. Using comprehensive transcontinental sampling, our...
