Testing a Global Positioning System on free-ranging badgers Meles meles

Introduction In the context of a study on the effects of landscape fragmentation on the ecology of a generalist carnivore, the European badger Meles meles, we deployed for the first time GPS (Global Positioning System) collars on this species. GPS need an unobstructed view to sky to find satellites signal and a reduced time of blinded period to reconstruct rapidly satellites ephemerid, in order to provide successful timed locations data (Tomkiewiecz et al. 2010).
