Alaska Peninsula brown bear
Alaska Peninsula brown bear
The Alaska Peninsula brown bear or "peninsular grizzly" is a colloquial nomenclature for a brown bear that lives in the coastal regions of southern Alaska, although according to other sources, it is a population of the mainland grizzly bear subspecies, or the Kodiak bear subspecies . Alaska Peninsula brown bears are very large, usually ranging in weight from 800 to 1,200 lb . They are found in high densities along the southern Alaskan coast due ...
not only to the large amount of clams and sedge grass but also to the annual salmon runs; this allows them to attain huge sizes, some of the biggest in the world. They may gather in large numbers at feeding sites, such as Brooks Falls and McNeil Falls, both in Katmai National Park near King Salmon. Biologists maintain that coastal ones are truly brown bears. However, it is considered correct to place all North American members of U. arctos in the subspecies horribilis except the giant Kodiak bears of Kodiak Island. To avoid confusion, many simply refer to all North American members, including Kodiaks, as "brown bears." Prized by hunters for their skulls and hides, up to 500 of Alaska's 1,500 brown bears killed yearly by hunters come from the Alaska Peninsula. To hunt this large bear, hunters must follow a variety of regulations, including bear bag limits, hunting fees and proper rifles.

The Prince of Wales flying squirrel, Glaucomys sabrinus griseifrons, is a subspecies of the northern flying squirrel. Glaucomys sabrinus griseifrons is endemic to Prince of Wales Island in Alaska and has a unique coloration compared to other subspecies of northern flying squirrel. It is whiter on the ventral side, darker on the dorsal side, and the head/neck area tend to be more gray than other subspecies. This subspecies is genetically distinct ...
from the northern flying squirrel from evidence found in mitochondrial DNA and microsatelite data. Adults are usually around 25-37 centimeters in length and 110-230 grams in weight. This subspecies is often considered a keystone species in the Southeastern Alaska area because it consumes and disperses conifer seeds and fungal spores into areas with little vegetation and sites of disturbance. The released fungi spores aid in the absorption of nutrients by plants and speed up regrowth in these areas.
