First upper molar and mandible shape of wood mice (Apodemus sylvaticus) from northern Germany: ageing, habitat and insularity
International audience The patterns of shape variation of the first upper molar and mandible have been investigated within and among wood mice (Apodemus as sex and age of the animals could be a source of within-group morphological variability interfering with among-groups patterns of differentiation...

International audience The patterns of shape variation of the first upper molar and mandible have been investigated within and among wood mice (Apodemus as sex and age of the animals could be a source of within-group morphological variability interfering with among-groups patterns of differentiation.

The increasing age of the animals, estimated by wear stages of the upper tooth row, caused significant variations in size and shape of the molars due to progressive abrasion of the cusps. It also involved shape changes of the mandible due to bone remodelling. However, these intrapopulational effects are of limited importance compared to geographic differentiation.
