| widespread co-occurrence of two distantly related mitochondrial genomes in individuals of the leaf beetle gonioctena intermedia. | mitochondrial genome heteroplasmy-the presence of more than one genomic variant in individuals-is considered only occasional in animals, and most often involves molecules differing only by a few recent mutations. thanks to new sequencing technologies, a large number of dna fragments from a single individual can now be sequenced and visualized separately, allowing new insights into intra-individual mitochondrial genome variation. here, we report evidence from both (i) massive parallel sequencing ... | 2017 | 29118243 |
| glacial survival of trophically linked boreal species in northern europe. | whether non-arctic species persisted in northern europe during the last glacial maximum (lgm) is highly debated. until now, the debate has mostly focused on plants, with little consideration for other groups of organisms, e.g. the numerous plant-dependent insect species. here, we study the late-quaternary evolution of the european range of a boreo-montane leaf beetle, gonioctena intermedia, which feeds exclusively on the boreal and temperate trees prunus padus and sorbus aucuparia using species ... | 2017 | 28592679 |
| multi-locus dna sequence variation in a complex of four leaf beetle species with parapatric distributions: mitochondrial and nuclear introgressions reveal recent hybridization. | while the importance for including multiple independent loci in phylogeographic studies is largely acknowledged, a majority of these still focus on a single species. we combine the study of multilocus dna sequence variation (one mitochondrial and four unlinked nuclear fragments) at both the inter- and intraspecific levels to explore the evolutionary history of four closely related specialized herbivorous insects (chrysomelidae, genus gonioctena). analyzing the sequences for samples collected acr ... | 2014 | 24821620 |
