July 14(ANI): In a new threat to a number of Arctic animals like polar bears, bowhead whales
and other such animals, the United States (US) has permitted an Italian multinational oil and gas company to go ahead with drilling plans in federal waters off Alaska.
For example, the Least Shrew (Cryptotis parva) rarely lives longer 2 y (Mock 1982), whereas Bowhead Whales
(Balaena mysticetus) have been estimated to live >200 y (George and others 1999).
We analyzed scarring data for Bering-Chukchi-Beaufort (BCB) Seas bowhead whales
(Balaena mysticetus) harvested by Alaska Native hunters to quantify the frequency of line entanglement, ship strikes, and killer whale-inflicted injuries.
Arctic Ocean tours are available to view beluga and bowhead whales
, walrus, bearded seals, and other artic marine mammals.
live beyond 200--which means that there are whales in our Arctic this summer that predate Canada.
A useful example of the difficulties generated by both subsistence and cultural arguments is the controversy surrounding bowhead whales
That is, until every September when, on Barter Island in the Arctic, up to Barter p to 80 polar bears gather to feast on the remains of bowhead whales
which have been caught by hunters.
Compared to the genomes of other creatures, the researchers found that bowhead whales
have unique alterations in a gene called ERCC1, which is involved in repairing damaged DNA.
Two studies conducted separately at UK and America looked into the genetic patterns of bowhead whales
which are considered to be the longest living mammals in the world, which live for more than 200 years.
In addition, the response of bowhead whales
, Balaena mysticetus, and possibly other cetaceans to these anthropogenic disturbances varies with behavioral activity (Beale and Monaghan, 2004; Ellison et al.
He's tired after a late night spent butchering one of three bowhead whales
that subsistence hunters towed in from the pewter-colored waters of the Chukchi Sea.
The study also illustrates the value of ancient DNA in answering questions about the impact of changing climate and human exploitation on genetic diversity in bowhead whales
