Bowhead whale - Wikipedia
The bowhead whale is the only baleen whale to spend its entire life in the Arctic and subarctic waters. [37] The Alaskan population spends the winter months in the southwestern Bering Sea . The group migrates northward in the spring, following openings in the ice, into the Chukchi and Beaufort seas. [ 38 ]
Sea ice directs changes in bowhead whale phenology through …
2023年2月7日 · As sea ice continues to decline, northward spring-time migration could shift earlier or more bowhead whales may overwinter at summer feeding grounds. Changes to bowhead whale migration could increase the overlap with ships and impact Indigenous communities that rely on bowhead whales for nutritional and cultural subsistence.
The bowhead whale (Balaena mysticetus) is an ice-associated mysticete that lives entirely in high-latitude circumpolar arctic seas. In Alaska, bowheads begin life in spring within the subzero ( C) waters of the ice-lead systems of the northern Bering, Chukchi and western Beaufort Seas. They may exceed 19 m in body length and 80 metric tons in ...
Trends in sea-ice cover within bowhead whale habitats in the …
2018年6月1日 · In this paper, we examine sea-ice conditions within known bowhead whale habitats by analyzing long-term (1979–2014) changes in sea-ice concentration and timing within the areas of the Alaskan Beaufort Sea where whales are counted via aerial surveys during the fall migration (Clarke et al., 2015) and within core-use areas delineated by ...
Shifts in bowhead whale distribution, behavior, and condition …
2023年3月1日 · Here, we examine how bowhead whale movements and behavior changed in response to potential ecological drivers by linking satellite tag data, collected during 2009–2019, with contemporaneous sea ice concentration data and numerical simulations of …
Killer whale presence drives bowhead whale selection for sea ice …
Using telemetry data from the eastern Canadian Arctic, we document pronounced and prolonged changes in bowhead whale behavior and selection for sea ice when under perceived predation threat by killer whales.
The influence of sea ice on the detection of bowhead whale calls
2022年5月20日 · Bowhead whales (Balaena mysticetus) face threats from diminishing sea ice and increasing anthropogenic activities in the Arctic. Passive acoustic monitoring is the most effective means for...
Killer whale presence drives bowhead whale selection for sea ice …
2020年3月24日 · Sea ice is considered quintessential habitat for bowhead whales, and ice-covered areas have frequently been interpreted as preferred bowhead foraging habitat in analyses that have not assessed predator effects.
The influence of sea ice on the detection of bowhead whale calls
Bowhead whales (Balaena mysticetus) face threats from diminishing sea ice and increasing anthropogenic activities in the Arctic. Passive acoustic monitoring is the most effective means for monitoring their distribution and population trends, based on the detection of their calls.
Gene flow on ice: the role of sea ice and whaling in shaping …
2012年10月18日 · Bowhead whales are highly adapted to polar sea ice and were targeted by commercial whalers throughout Arctic and subarctic seas for at least four centuries, resulting in severe reductions in most areas.
