Population limitation and the wolves of Isle Royale
Population regulation for gray wolves in Isle Royale National Park, Michigan, was examined in 1987-1995 when wolves were in chronic decline following a crash of the population in 1981-1982. Canine parvovirus (CPV-2) was probably influential during the crash, but it disappeared by the late 1980s. Hig...
