Life As a Po­lar Bear Isn't All Mis­ery and Star­va­tion...

Science Illustrated - - MEGAPIXEL // POLAR BEARS -

While the num­ber of po­lar bears is decreasing else­where, the pop­u­la­tion is grow­ing on Sval­bard. The most re­cent count on the Nor­we­gian is­lands in the Bar­ents Sea es­ti­mated a pop­u­la­tion of 975 in­di­vid­u­als, which is 300 more than in the 2004 count. The fe­males give birth in caves dur­ing the win­ter and cubs emerge for the first time on the sea ice, when they are two to three months old. The amount of sea ice varies con­sid­er­ably from year to year, but the long-term trend is for the ice to cover a smaller part of the Arc­tic, which will also af­fect the po­lar bears on Sval­bard.
