Abstract
We analysed space use strategies in two populations of Alpine Rock Ptarmigan Lagopus muta helvetica considering three topographical variables (elevation, slope and aspect) to investigate whether populations living at range margins can adapt to suboptimal conditions by exploiting the available habitat differently. Selection for topographic features differed between populations, suggesting that Rock Ptarmigan adapt their habitat selection to local availability. Therefore, we suggest considering a wide range of habitat parameters when planning conservation strategies for species living at the margins of their range.
Financial support was provided by the Piedmont Region, and this study was part of ALCOTRA 2007–2013. Thanks to Piedmont Region personnel: V. Bosser Peverelli, S. Grignolio; Gran Paradiso National Park personnel: B. Bassano, R. Viterbi and all of the wardens; and CN4 hunting district personnel: C. Lovera. Moreover we would like to thank people that helped during our field activities: Marta and Cristiano (CACN4), and all the hunters that helped with their dogs. We thank also two anonymous reviewers who helped in improving the manuscript.
