The evolution of baleen constituted a major evolutionary change that made it possible for baleen whales to reach enormous body sizes while filter feeding on tiny organisms and migrating over tremendous distances. Bowhead whales (Balaena mysticetus) l

Adapted to life in cold, polar waters, might Arctic fishes be ill equipped to deal with the rising temperatures expected from global climate change? Little is currently known about differences in tolerance among the diverse collection of nearshore, e

We examined the effects of temperature and salt concentration on growth of the freshwater oomycete Saprolegnia parasitica that has recently (since 2013) been found to infect an important subsistence fish (in Iñupiaq, Aanaakłiq; broad whitefish, Cor

Great whales have been detected using very‐high‐resolution satellite imagery, suggesting this technology could be used to monitor whales in remote areas. However, the application of this method to whale studies is at an early developmental stage

Baleen, a unique oral α-keratin, has flat cortical layers enclosing hollow horn tubules. Baleen grows continuously to replace erosive loss from feeding-related wear. This is essential for maintaining efficient filtration over a whale’s long life h

One of the most pervasive signals of global climate change is altered patterns of distribution with trends towards poleward shifts of species. While habitat loss and destruction has severed connections between people and salmon in many locales, salmo

The Arctic currently holds a prominent place in global policy. It is a sparsely populated region experiencing major consequences of global change, such as climate change, shifting demographics, and globalization. These substantial and rapid changes c

Based on several lines of evidence, bowhead whales appear to have metabolic rates that are lower than other similar-sized baleen whales. Low metabolic rates offer some disadvantages, such as slow growth rates, delayed maturation, and long intercalf i

Bering–Chukchi–Beaufort Sea bowhead whales are born at about 4.2 m in length and 1000 kg, in lead systems along the NW Alaskan coast. Bowheads in the other northern stocks are also born in ice-covered seas. Maximum body lengths (standard measure)
