在白令海，夏季海冰覆盖的变暖和减少正在将物种范围推向北极。坦纳蟹（Chionoeclumbairdi）是白令海东南部的一个重要商业物种，分布在北纬62º的北部范围边缘。本文利用夏季在太平洋亚北极/北极区采集的浮游生物样品，首次报道了C. 1991年在圣劳伦斯岛南部，甚至在1992年穿越白令海峡进入楚科奇海。我们认为，长的南极阶段（3-5个月），结合海洋环流，可能有助于最终的长途运输。
In the Bering Sea, warming and reduction of summer sea-ice cover are driving species ranges towards the Arctic. Tanner crab,Chionoecetes bairdi, is a commercially important species in the SE Bering Sea with a northerly range margin in 62ºN. In this paper, using plankton samples collected in the Pacific sub-Arctic/Arctic sector during summer, we report for the first time the presence of larval stages (zoea II) ofC. bairdifar from its northern limit of the distribution, in the south of St. Lawrence Island during 1991, and even crossing the Bering Strait into the Chukchi Sea during 1992. We suggest that the long planktonic phase (3–5 months), in combination with the oceanographic circulation, may facilitate eventual long-distance transport.
