  • 1 POLAR BEAR (Ursus Maritimus): Chukchi/Bering Seas Stock STOCK
    Revised: 01/01/2010 POLAR BEAR (Ursus maritimus): Chukchi/Bering Seas Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Polar bears are circumpolar in their distribution in the northern hemisphere. They occur in several largely discrete stocks or populations (Harington 1968). Polar bear movements are extensive and individual activity areas are enormous (Garner et al. 1990, Amstrup et al. 2000). The parameters used by Dizon et al. (1992) to classify stocks based on the phylogeographic approach were considered in the determination of stock separation in Alaska. Several polar bear stocks are known to be shared between countries (Amstrup et al. 1986, Amstrup and DeMaster 1988). Lentfer hypothesized that in Alaska two stocks exist, the Southern Beaufort Sea (SBS) and the Chukchi/Bering seas (CBS), based upon: (a) variations in levels of heavy metal contaminants of organ tissues (Lentfer 1976, Figure 1. Map of the Southern Beaufort Sea and the Chukchi/ Lentfer and Galster 1987); (b) morphological Bering seas polar bear stocks. characteristics (Manning 1971, Lentfer 1974, Wilson 1976); (c) physical oceanographic features which segregate the Chukchi Sea and Bering Sea stock from the Beaufort Sea stock (Lentfer 1974); and (d) movement information collected from mark and recapture studies of adult female bears (Lentfer 1974, 1983) (Figure 1). Information on contaminants (Woshner et al. 2001, Evans 2004a, Evans 2004b, Kannan et al. 2005, Smithwick et al. 2005, Verreault et al. 2005, Muir et al. 2006, Smithwick et al. 2006, Kannan et al. 2007, Rush et al. 2008) and movement data using satellite collars (Amstrup et al. 2004, Amstrup et al. 2005) continue to support the presence of these two stocks.

Inuit and their Chukchi neighbors have always been highly mobile, but the imposition of three international borders in the region constrained travel, trade, hunting, and resource stewardship among neighboring groups. Colonization, assimilation, and enforcement of national laws further separated those even from the same family. In recent decades, Inuit and Chukchi have re-established many ties across those boundaries, making it easier to travel and trade with one another and to create new institutions of environmental management. To introduce Indigenous perspectives into the discussion of transboundary maritime water connections in the Arctic, this paper presents personal descriptions of what those connections mean to people who live and work along and across each of the national frontiers within the region: Russia–U.S., U.S.–Canada, and Canada–Greenland.

Lowry, Alaska Beluga Whale Committee and University of Alaska Fairbanks, 73-4388 Paiaha Street, Kailua Kona, HI 96740 USA John J. Citta, Alaska Department of Fish and Game, 1300 College Road, Fairbanks, AK 99701 USA Greg O’Corry-Crowe, Harbor Branch Oceanographic Institute, Florida Atlantic University, Fort Pierce, FL 34946, USA Kathryn J. Frost, Alaska Beluga Whale Committee. 73-4388 Paiaha Street, Kailua Kona, HI 96740 USA Robert Suydam, North Slope Borough, Box 69, Barrow, AK 99723, USA 1. Distribution and stock identity The eastern Chukchi Sea (ECS) beluga stock occurs in the lagoons and adjacent waters of the ECS in late spring and early summer (Frost et al. 1993). Individuals of this stock range widely throughout the ECS and Beaufort Sea and into the Arctic Ocean during summer and early fall (Suydam 2009, Hauser et al. 2014) and then move through the Bering Strait into the Bering Sea in the winter, returning to the Chukchi Sea the following spring (Citta et al. 2017). The non-uniform distribution of beluga whales in coastal waters of the Bering, Chukchi, and Beaufort Seas in summer is indicative of likely population subdivision and formed the basis for original, but provisional, stock designations (Frost and Lowry 1990). It was recognized at the time that identification of more biologically meaningful stocks would require genetic studies to elucidate the underlying patterns of demographic and reproductive relationships among seasonal groupings (O’Corry-Crowe and Lowry 1997).
