Increased gene sampling strengthens support for higher-level groups within leaf-mining moths and relatives (Lepidoptera: Gracillariidae)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...
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...
Phylogeny, biogeography, and host-plant association in the subfamily Apaturinae (Insecta: Lepidoptera: Nymphalidae) inferred from eight nuclear and seven mitochondrial genesIssei 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...
The utility of indels in population genetics: the Tpi intron for host race genealogy of Acrocercops transecta (Insecta: Lepidoptera)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...
Multiple host shifts between distantly related plants, Juglandaceae and Ericaceae, in the leaf-mining moth Acrocercops leucophaea complex (Lepidoptera: Gracillariidae)Issei Ohshima
Systematic Entomology, Department of Ecology and Systematics, Graduate School of Agriculture, Hokkaido University, Sapporo 060 8589, Japan
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...
Genetic mechanisms preventing the fusion of ecotypes even in the face of gene flowIssei Ohshima
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...
