Evolutionary history of two allopatric Terricola species (Arvicolinae, Rodentia) from molecular, morphological, and palaeontological data

2008

To investigate the phylogenetic and phylogeographical relationships of arvicolines, we use several Western European ground voles. More particularly, our study is focused on Microtus (Terricola) savii and M. (T.) pyrenaicus. These two allopatric species are usually considered as having originated from the same ancestor, possibly M. (T.) mariaclaudiae. We propose molecular and morphological approaches: nucleotidic data from the mitochondrial cytochrome b and 12S rRNA genes and global morphological analyses from the first lower molar. Four other Terricola species (multiplex, lusitanicus, duodecimcostatus, subterraneus) were added to the data set for both analyses, and two other vole species (C…

Analyse odontométrique comparée de populations du campagnol des neiges Chionomys nivalis (Martins, 1842) (Rodentia, Arvicolinae).

2007

14 pages; La morphométrie comparée de la première molaire inférieure (M1) de onze populations du campagnol des neiges Chionomys nivalis (Rodentia, Arvicolinae) (Martins, 1842) du Pléistocène supérieur et de l'Holocène de France, d'Allemagne et de Roumanie, montre une nette différenciation morphologique entre les populations de ces trois pays, exprimée par un gradient morphologique est-ouest. A l'échelle du pays, des divergences morphologiques, plus modérées, sont observées, en particulier chez les populations de France et des Carpates méridionales et occidentales.
