Status and delineation

Kara Sea subpopulation mapThe Kara Sea area. See also the complete map (all subpopulations).

The Kara Sea (KS) subpopulation overlaps in the west with the Barents Sea (BS) subpopulation in the area to the east of Franz Josef Land and includes the Novaya Zemlya archipelago. Data for KS and BS, in the vicinity of Franz Josef Land and Novaya Zemlya, are mainly based on dated aerial surveys and den counts (Parovshivkov 1965; Belikov and Matveev 1983; Uspenski 1989; Belikov and Gorbunov 1991; Belikov et al. 1991; Belikov 1993). Telemetry studies of movements have been done throughout the area, but data to define the eastern boundary are incomplete (Belikov et al. 1998; Mauritzen et al. 2002). Using polar bear samples from KS from the 1990s, at a global level, polar bears in KS belong to the Eastern Polar Basin genetic cluster (together with polar bears from Barents Sea, Laptev Sea); gene flow suggests substantial directionality (29-fold difference) from the Eastern Polar Basin to the Western Polar Basin (Peacock et al. 2015).
