Reappraisal of ‘chronospecies' and the use of Arvicola (Rodentia, Mammalia) for biochronology.
2008
13 pages; International audience; The water vole, genus Arvicola, is characterised by a broad geographic distribution throughout Europe and is widespread during the late Middle and Upper Pleistocene. This genus is used as a major biostratigraphic tool within the Quaternary. Specific determinations using the Schmelzband-Differenzierung-Quotient or SDQ have identified many chronospecies within the fossil species Arvicola cantiana (Hinton, 1910). As SDQ calculation remains limited, this study reappraises the Arvicola genus in terms of morphodiversity and morphospace using outline analysis which takes into account the tooth as a whole. Outline analysis suggests that one single species of Arvico…
Les micromammifères du département de l'Isère (Rhône-Alpes, France) : répartition par district naturel.
2013
Micromammals of the French department of Isère (Rhône-Alpes) : distribution by natural district. - This article presents the distribution of the species of micromammals of the department of Isère (Rhône-Alpes, France), by natural district from the analysis of 78,100 specimens inventoried and registered in a database of the micromammals of the department. For each species, a comparison of its distribution is made between districts. This synthesis is a photograph of the current knowledge and it also allows to define the future researches to improve the knowledge and the protection of micromammals in Isère.
