La conservazione dell'Orso bruno (Ursus arctos) in Appennino: il supporto della genetica non invasiva

Conservation of the brown bear Ursus arctosin the Apennines: a non- invasive genetic approach. Molecular techniques were used to assess individual identifica- tion for 24 brown bears (Ursus arctos)from the Apennine population through noninvasive sampling. Shed hairs were collected and used as a source of DNA to derive single genoty- pe profiling at 12 microsatellite loci. Genotypes of 11 bears were obtained from tissues or blood of dead or caught animals. Average expected heterozygosity (H E = 0.432) and mean
