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 FILE DESCRIPTION: db.txt index transect file name: transect name date: on eight digits, '19921014' reads 14/10/1992 ID: interval ID = number (within a given transect at a given date) Habitat: (indicative) the habitat category crossed. Just mentioned when passing from one category to the other; the following intervals are assumed to belong to this habitat ma1: number of Microtus holes; A, 1-5 holes; B, 6-10 holes; C > 10 holes ma2: answered only if A, B, or C are defined in ma1; NA, not answered (ma1 not defined), 0, zero faeces, 1 some faeces or fresh indices (runways with grass freshly cut, etc.); 2 many faeces in heaps long: longitude (WGS84) lat: latitude (WGS84) StudyAreaBoundingBox.kml Bounding box of the study area.
