Relative density variations of common vole population based on index transect, Septfontaines - Le Souillot, France (1990-2000)

Transects were walked from village to village along a transect line. Common vole (Microtus arvalis) activity indices were recorded in every ten pace interval from October 1990 to April 2000. In 2014, the geographical coordinates of each interval has been computed by spatial interpolation based on georeferenced maps. Therefore, users must be aware that individual locations of intervals are unprecise, but not the general bearing of the transect in the landscape and interval succession. See articles published for reference and more details.

During the same time span, small mammmals (including common voles) were sampled using live-trapping, see 10.5281/zenodo.6997316
