Book excerpt: The Bowhead Whale: Balaena mysticetus: Biology and Human Interactions covers bowhead biology from their anatomy and behavior, to conservation, distribution, ecology and evolution. The book also discusses the biological and physical aspects of the Arctic ecosystem in which these whales live, with careful attention paid to the dramatic changes taking place. A special section of the book describes the interactions of humans with bowheads in past and present, focusing on their importance to Indigenous communities and the challenges regarding entanglement in fishing gear, industrial noise and ship strikes. This volume brings together the knowledge of bowheads in one place for easy reference for scientists that study the species, marine mammal biologists, but, equally important, for everyone who is interested in the Arctic. - Presents the only current book dedicated to this species - Includes short, high-impact chapters that make it possible to review all bowhead biology in one compact volume - Illustrated with never-before published photos of bowheads in their natural environment - Provides a platform for an in-depth understanding of indigenous whaling

Available in PDF, EPUB and Kindle. Book excerpt: "This thesis describes investigations on bowhead whales (Balaena mysticetus) specifically on age, growth, morphology and energetics. The examined whales were harvested by Inupiat whale hunters primarily in Barrow, Alaska since the 1970s. Bowheads are robust cetaceans reaching 19m in length and inhabit most of the ice-covered waters of the circumpolar Arctic. They have the thickest blubber (>̲ 35 cm) of any cetacean and the longest and most extensive baleen apparatus. Bowheads grow rapidly from 4 to ~8 m in their first year, after which they experience a 2-3 year growth pause in both body length and mass. However, the baleen continues to grow during this period. Sex differences are minimal but adult females tend to grow longer than males and have smaller pectoral limbs. Several lines of evidence, including the recovery of 19th century stone weapons from recently harvested whales, suggest bowheads are the longest-lived mammals. Age was estimated using the aspartic acid racemization technique which suggests that sexual maturity occurs in the mid-20s with maximum ages to 200 years. All harvested whales examined showed strong thermal gradients through their blubber and through the muscle, the latter being atypical of most mammals. The deep body temperature averaged 33.8° C which is lower than in other non-hibernating eutherian mammals. An elevation of body temperatures in pursued whales was not noted. Resting metabolic rates for whales were estimated using a heat-loss technique. The thermal conductivity of the blubber averaged 0.23 Wm−1K−1, similar to that of other whales and marine mammals. Heat flux rates were highest for the palatal rete, flukes, and tongue, and lowest for the thorax. The estimated metabolic rates were considerably lower than predicted by the Kleiber regression. These investigations suggest that bowhead whales arc unique among mammals in several respects including: their extensive baleen rack, massive head, great longevity, lower resting metabolic rates and body temperatures than in other cetaceans, and an approximately 3 year growth pause following weaning. Their thick blubber likely buffers bowheads against high variability in primary and secondary productivity in arctic seas"--Leaf iii.
