European hedgehog populations belonging to Erinaceus europaeus and E . concolor have been investigated by mitochondrial DNA analysis. A 383 bp fragment of the cytochrome b gene has been sequenced and maximum parsimony and neighbour‐joining trees of Tamura–Nei genetic distance values have been constructed. Similar topologies have been produced by both methods, showing a deep divergence between E . europaeus and E . concolor and a further subdivision of each species into a western and an eastern clade. A comparison with previously published allozyme data is made, and concordant and discordant patterns are discussed. The influence of Pleistocene glaciations on the observed pattern of divergence is inferred.
Mice of the Peromyscus aztecus species group occur at mid to high elevations in several mountain ranges in the highlands of Middle America (Mexico and Central America), a region...
Phylogenies are extremely useful tools, not only for establishing genealogical relationships among a group of organisms or their parts (e.g. genes), but also for a variety of re...
Combining phylogeographic data from mitochondrial DNA (mtDNA) of Nearctic and Palearctic freshwater and anadromous fishes, we used a comparative approach to assess the influence...
Abstract We examined intra‐specific phylogenetic relationships in leatherside chub, Gila copei . The complete mitochondrial (mt) cytochrome b gene (1140 bp) was sequenced for 30...
The Quaternary cold periods in Europe are thought to have heavily influenced the amount and distribution of intraspecific genetic variation in both animals and plants. The phylo...
