The California grizzly (''Ursus arctos californicus'') is an extinct subspecies of the grizzly, the very large North American brown bear. "Grizzly" refers to the golden and grey tips of its hair. Genetically, North American grizzlies are closely related; in size and coloring, the California grizzly was much like the grizzly of the southern coast of Alaska. In California, it was particularly admired for its beauty, size, and strength. The grizzly became a symbol of the Bear Flag Republic, a moniker that was attached to the short-lived attempt by a band of American settlers to break away from Mexico. Later this rebel flag became the state flag, and then California was known as the "Bear State." In 1866, a grizzly weighing was killed in Valley Center, California, the biggest bear ever found in California,〔(【引用サイトリンク】url=http://www.vchistory.org/index.php/standing-exhibits/grizzly-bear/ )〕 unsurpassed until John Lang shot the world's biggest bear — — near his ranch by Canyon Country, in 1873.〔(【引用サイトリンク】url=http://oldsite.the-signal.com/?module=displaystory&story_id=49338&format=html )〕 California still has habitat for about 500 grizzlies, and if the North Cascade population recovers and expands, it may be introduced to California. There are, however, only about 20 of these bears remaining in that ecosystem. In 2014 the US Fish and Wildlife Service received a petition to reintroduce the grizzly to California. This reintroduction would be from the very closely related Rocky Mountain grizzly. ==Nomenclature== "The specific status of North American grizzly bears is one of the most complex problems of mammalian taxonomy. The difficulty stems directly from the work of Merriam (1918), who concluded that there are 86 forms of grizzlies (and brown bears) in North America." Later, all North American grizzlies were scientifically grouped together as one unique species until DNA testing revealed that they should properly be grouped taxonomically in the same species as the other brown bears. Californian grizzlies were classified by Merriam into many species and subspecies but today the only subspecies is the ABC Islands bears. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「California grizzly bear」の詳細全文を読む スポンサード リンク
