The Cаlifоrniа Depаrtment оf Fish and Wildlife is develоping a plan to connect mountain “habitat islands” that are separated by open areas of flat, arid land in the deserts of southeastern California. These mountain areas are habitats for desert bighorn sheep (Ovis canadensis), which move extensively among the islands through habitat corridors. The habitat corridors provide opportunities for recolonization, seasonal migration, and maintenance of genetic variation among the metapopulation of desert bighorn sheep. (a) Describe one density-dependent factor and one density-independent factor that could affect the populations of desert bighorn sheep. (Make sure to clearly describe your answers and write in complete sentences.)
