Conservation introduction of the threatened Apennine chamois Rupicapra pyrenaica ornata: Post-release dispersal differs between wild-caught and captive founders

Sixteen Apennine chamois Rupicapra pyrenaica ornata (10 females, 6 males) were released into a protected area, the Sibillini Mountains National Park, Central Apennines, Italy, and monitored using global positioning system radio tags during 2008–2010. Founders caught in the wild (n58) and those reared in large enclosures (n58) differed in movement frequency (inter-fix distance per hour) and maximum distance covered (from the release site) in the first 5 months after release: both were significantly greater in wild individuals, males moved significantly more than females, wild individuals shifted their home ranges significantly more often than captive ones, and no differences were observed between the sexes or age classes. A mixed strategy of selection of wild and captive founders has proven successful in preventing large movements in the initial stages of release yet still providing sufficient opportunity to avoid inbreeding depression.
