Hydrodynamic patterns associated with echelon formation swimming by feeding bowhead whales (Balaena mysticetus
Age and growth estimates of Bowhead Whales (Balaena mysticetus
) via aspartic acid racemization.
Whales have a rather wide range of values of [C.sub.E], larger for the hydrodynamically "better shaped" animals; for example, the sei whale Balaenoptera borealis has approximately 10 times greater capacity-efficiency factor than the bowhead whale Balaena mysticetus
. The main predator of whales--the killer whale Orcinus orca--has approximately twice as large a value of [C.sub.E] as the sei whale and comes close to the characteristics of its relative, the bottlenose dolphin Tursiops truncatus.
Having hunted these whales for centuries, the Inupiat are keen observers of the bowhead (Balaena mysticetus
These first hunters caught up to 16 ft (5 m) long belugas (Delphinapterus leucas) and narwhals (Monodon monoceros), but also hunted the slow-moving 46-57 ft (14-17.5 m) long bowhead whales (Balaena mysticetus
) when they cruised close to the ice and, in the north Pacific, the gray whale (Eschrichtius robustus).
This means that biological factors will not be the only considerations determining whether species such as the Peary (Rangifer tarandus pearyi) and woodland Caribou and the bowhead whale (Balaena mysticetus
), species that are an important part of aboriginal hunting traditions in northern Canada, and marine species such as the Atlantic salmon (Salmo salar) and the Atlantic cod (Gadus morhua) which are economically important to the people of eastern Canada, are listed.
A history of sea ice in the Canadian Arctic Archipelago based on postglacial remains of the Bowhead Whale (Balaena mysticetus
Bowheads (Balaena mysticetus
) and other large baleen whales have been part of Inuit and Yupik maritime harvesting economies for over 1000 years.
