摘要: Recovery of gray wolf (Canis lupus) populations in North America depends on minimizing human-caused mortality and enhancing migration from stable source to suitable habitat unoccupied by wolves. We used a combination field observation DNA microsatellite genotyping examine natural colonization Glacier National Park, Montana, surrounding lands. found high genetic variation the colonizing population, showing that these packs were founded multiple, unrelated wolves Canada. High dispersal rates, long distances, lack founding population bottleneck indicate United States Canada should be viewed managed as single population. Restoration artificial transplants Alberta Yellowstone Park central Idaho began 1995. The transplanted will likely aid demographic recovery, but permanently retaining require assuring gene flow throughout Rocky Mountains. La recuperacion de poblaciones lobos grises en Norte depende la minimizacion mortalidad causada por humanos y el mejoramiento migraciones estables hacla habitats no ocupados lobos. Usamos una combinacion observaciones campo genotipos expresados microsatelites ADN para examinar colonizacion del Parque Nacional Glacier, Montana las tierras circunvecinas. Encontramos aita variacion genetica poblacion colonizadora, lo que muestra estas manadas fueron fundadas multiples estaban relacionados entre si. Las altas tasas dispersion, grandes distancias dispersion carencia un cuello botella fundadora indica los iobos Estados Unidos deberian ser vistos manejados como solo poblacion. La restauracion medio transplantes artificiales hacia zona iniciaron Los transplantados ayudaran probablemente demografica, pero retencion permanente alta E. U. requerira garantizar flujo genes traves Montanas Rocallosas.
