An opportunistic predator, the stoat searches every burrow and hole for signs of prey species. The enormous benefit that salmon provide for countless species and the overall health and function of the coast is what makes salmon a keystone species an integral species which ecosystems depend on, with drastic changes resulting if they are removed. The capybara is the only rodent larger than the North American beaver. The caribou feeds on lichens, leaves of birches and willows, grasses, and sedges. endstream During the final period of maximum cold temperatures (23,000 to 16,500 years ago) in the latter part of the Pleistocene Ice Age (which ended 11,700 years ago), species that now constitute the taiga were displaced as far south as 30 N latitude by the continental glaciers of Europe, Asia, and North America and by the hyperarid and extremely cold environments of unglaciated Asia and North America. An example would be a Ponderosa Pine in Northern Arizona or a Beaver in a wetland area. Named for the gold-brown color of its plumage, the golden eagles wingspan can reach 88 (224 cm). Another member of the mustelid family, martens are much smaller than their wolverine cousins. The northern flying squirrel has been considered a keystone species because of its role in facilitating an obligate ecological relationship between mycorrhizal fungi and dominant canopy tree species (Maser and Maser 1988).The squirrel feeds on truffles and deposits fecal pellets with fungal spores and nitrogen-fixing bacteria across the forest floor (Maser and Maser 1988). Many areas that are now islands were then connected to the nearby mainland; e.g., the British Isles were linked to Europe.
