Narrow-headed vole molar wear data for specimens collected between 1999 and 2019 on the Yamal Peninsula, Russia, published in Ungar et al. (2021)

This dataset contains data for a study of mesoscale tooth wear (mesowear, chipping, facets, and other wear attributes) in narrow-headed voles, Microtus gregalis, at three sites along a latitudinal gradient of ecological subzones in the Yamal Peninsula of the Russian Arctic. These sites include Kharp in the forest–tundra ecotone, Erkuta in the low Arctic, and Sabetta at the border between the low and the high Arctic. A total of 117 specimens were included and eight variables were used to characterize mesoscale tooth wear. The purpose of this dataset is to determine whether mesoscale wear of rodent molars tracks habitats in the Arctic.
