Using phylogeography to promote dormouse conservation: the case of Muscardinus avellanarius (Rodentia, Gliridae)

2012

this study describes the phylogeographic history of the common dormouse, Muscardinus avellanarius rodent strictly protected in europe (habitat directive, annex iv; Bern convention, annex iii). We analyzed the genetics of 120 common dormice across the species’ range, using sequences data from the mitochondrial cytochrome b gene (704 pb). the dataset obtained was analyzed using different phylogenetic reconstructions as well as other methods adapted to phylogeography. A complex phylogeographic pattern has been retrieved from the mitochondrial dnA gene, with the presence of two highly divergent lineages. these two lineages are themselves subdivided into five sublineages, which should be regarde…

Mitochondrial phylogeography of the edible dormouse (Glis glis) in the western Palearctic region

2010

International audience; This study describes in detail the phylogeoraphic pattern Of the edible dormouse (Glis glis) a European rodent With pronounced hibernating behavior We Used sequences of 831 base pairs of the mitochondrial DNA cytochrome-b gene from 130 edible dormice collected at 43 localities (throughout Its distribution. Our results reveal presence of 3 main haplogroups: Sicilian, South Italian (restricted to the Calabrian region) (a widespread lineage corresponding to all remaining western, central. and eastern European populations). Examination of paleontological data confirms refugial regions for G,Its in the 3 Mediterranean peninsulas, although overall low genetic diversity is …

Evidence of a complex phylogeographic structure in the common dormouse, Muscardinus avellanarius (Rodentia: Gliridae)

2012

Contact: amouton@ulg.ac.be; International audience; This is the first mitochondrial phylogeography of the common dormouse, Muscardinus avellanarius (Linnaeus, 1758), a hibernating rodent strictly protected in Europe (Habitat Directive, annex IV; Bern Convention, annex III). The 84 individuals of M. avellanarius, sampled throughout the distributional range of the species, have been sequenced at the mitochondrial DNA gene (cytochrome b, 704 base pairs). The results revealed two highly divergent lineages, with an ancient separation around 7.7 Mya and a genetic divergence of 7.7%. Lineage 1 occurs in Western Europe (France, Belgium, and Switzerland) and Italy, and lineage 2 occurs in CentralNor…
