Observational data :
Field collection - Counts were performed along geo-referenced transects, 1–2 km in length, distributed over the Doubs Department. Every spring, counts were performed along each transect over 3–4 nights. These counts were performed at least 1 h after sunset in a car (maximum speed of 20 km/h)and by 4 people: a driver, a data recorder and 2 observers. Observations were made using 100-W spotlights and binoculars for species identification. Double counting was unlikely because transects were relatively straight and observers were careful about animal movements. Among the 3-4 counts, only the maximum number of animal of a given species was filed (thus providing a lower limit for the number of animal of this species present)
