    Akito Y Kawahara
    Department of Entomology, University of Maryland, College Park, MD, USA
    BMC Evol Biol 11:182. 2011
    ..Each data set was subject to five different models and partitioning schemes of non-synonymous and synonymous changes. Statistical significance of non-monophyly was examined with the Approximately Unbiased (AU) test...
  2. doi request reprint Differential introgression causes genealogical discordance in host races of Acrocercops transecta (Insecta: Lepidoptera)
    Issei Ohshima
    Systematic Entomology, Department of Ecology and Systematics, Graduate School of Agriculture, Hokkaido University, Sapporo 060 8589, Japan
    Mol Ecol 19:2106-19. 2010
    ..Thus, the results show that a low level of gene flow coupled with the inflexible female host preference differentiates histories of divergence between maternally and biparentally inherited genes in this host race system...

    Issei Ohshima
    National Institute for Basic Biology, Okazaki 444 8585, Japan
    Mol Phylogenet Evol 57:1026-36. 2010
    ..Our phylogenetic results are inconsistent with the previously accepted apaturine genus groups and indicate that their higher classification should be reconsidered...

    Issei Ohshima
    Division of Evolutionary Biology, National Institute for Basic Biology, Okazaki 444 8585, Japan
    Mol Phylogenet Evol 59:469-76. 2011
    ..We concluded that indel characters have the potential to be a powerful tool in the analysis of population genetics and population structure as well as in the detection of gene flow...

    Mol Phylogenet Evol 38:231-40. 2006
    ..These results imply that there are ecological and biochemical factors that promote host shifting between Juglandaceae and Ericaceae despite the two families being not closely related...

    Department of Ecology and Systematics, Graduate School of Agriculture, Hokkaido University, Sapporo 060 8589, Japan
    Sci Rep 2:506. 2012
    ..Thus, simple genetic controls with contrasting dominance directions in host-adaptation traits function as barriers to prevent a fusion of host races...
