Genetic structure of a European forest species, the edible dormouse ( Glis glis ): a consequence of past anthropogenic forest fragmentation?
2019
International audience; The genetic structure of forest animal species may allow the spatial dynamics of the forests themselves to be tracked. Two scales of change are commonly discussed: changes in forest distribution during the Quaternary, due to glacial/interglacial cycles, and current fragmentation related to habitat destruction. However, anthropogenic changes in forest distribution may have started well before the Quaternary, causing fragmentation at an intermediate time scale that is seldom considered. To explore the relative role of these processes, the genetic structure of a forest species with narrow ecological preferences, the edible dormouse (Glis glis), was investigated in a set…
Hypsodont Myomiminae (Gliridae, Rodentia) from five new localities in the Lower Miocene Tudela Formation (Bardenas Reales, Ebro Basin, Spain) and the…

The hypsodont Myomiminae Daams, 1981 (Gliridae) from the lower part of the Tudela Formation (Ebro Basin) are described. Five localities (CH1, CA2, CA3, CA4 and CC1) of this formation contain remains of the hypsodont genus Armantomy de Bruijn, 1966 and CC1 has also yielded Praearmantomys de Bruijn, 1966. Despite the poor material, we can identify the taxa A. cf. bijmai, A. daamsi (de Visser in Álvarez-Sierra, Daams, Lacomba, López Martínez, Van Der Meulen, Sesé & De Visser, 1991), A. cf. parsani, A. cf. jasperi and cf. P.crusafonti, which are characteristic of the Agenian and Ramblian continental stages. These data allow identification of the Agenian-Ramblian boundary in the Tudela Formation…
Mitochondrial phylogeographic of the common dormouse, Muscardinus avellanarius (Rodentia: Gliridae)

New data on the taxonomy of the endemic myomiminae (gliridae, rodentia) from the late miocene-early pliocene of gargano (southern Italy) with the des…

The Late Miocene-Early Pliocene “Terre Rosse” vertebrate assemblages, found in the palaeokarst fissure fillings of the Apricena-Poggio Imperiale limestone quarries (North-Western side of the Gargano promontory, southern Italy), document a very long and complex history of endemic populations of a palaeoarchipelago. That history developed in at least four populating phases, which are characterised by changes in faunal diversity and include taxa with different degree of endemism. They have been subject of several studies since the beginning of the 1970s and deserve a particular attention for their evolutionary and palaeogeographical implications. The sampling of the “Terre Rosse” fissure filli…
A new species of glirid rodent Vasseuromys from the Aragonian (Miocene) of the Ebro Basin (North−Eastern Spain)
2012
We describe a new species of Vasseuromys from the locality of Pico del Fraile 2 (PF2) in the Ebro Basin of northeastern Spain, which has yielded a fauna comprising several rodents and insectivores (Eumyarion cf. weinfurteri, Mega−cricetodon cf. primitivus, Democricetodon aff. hispanicus, Spermophilinus cf. besana, Microdyromys cf. legidensis, Galerix sp., and Lagomorpha indet.) indicative of Aragonian zones C or D. Vasseuromys cristinae sp. nov. differs from other Vasseuromys species in the constant presence of four extra ridges on the lower molars, one of them being connected to the posterolophid in the posterior valley, as well as three extra ridges on the upper molars, with none of them …
Vasseuromys rambliensis sp. nov. (Gliridae, Mammalia) from the Ramblian (Lower Miocene) of the Tudela Formation (Ebro basin, Spain)
2012
In this paper, a new species of Vasseuromys, V. rambliensis sp. nov., from the locality Pico del Fraile 1 (PF1, Ebro basin, North-eastern Spain) is described. The association of Ligerimys, Peridyromys murinus and Simplomys simplicidens, and the absence of Eucricetodon and Democricetodon, allows dating of the PF1 locality as Late Ramblian (Early Miocene, MN3, local zone A). Main diagnostic features of V. rambliensis sp. nov. are the presence of four extra ridges in the lower molars, a very reduced anterotropid and a metaloph connected to the posteroloph and not to the protocone. The size and morphology of V. rambliensis sp. nov. are very close to V. bacchius from the upper part of unit MN2, …
