Available in PDF, EPUB and Kindle. Book excerpt: Bowhead whales are amazing creatures that often live lives longer than humans! These whales live in Arctic waters near the North Pole, smashing through thick ice to reach the surface to breathe. Using their baleen, these large mammals feed on tiny animals swimming in the cold waters, while thick blubber keeps them warm in frigid temperatures. Readers explore their everyday lives using the latest scientific research about these long-living animals, and colorful photographs show these gigantic creatures and their unique features up close and personal.

Download or read book Ice Whale written by Jean Craighead George and published by Penguin. This book was released on 2014-04-03 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the most celebrated children’s nature writer of our time comes a posthumous new novel in the tradition of her Newbery award-winning Julie of the Wolves In 1848, a young boy witnesses a rare sight—the birth of a bowhead, or ice whale, he calls Siku. Years later, he unwittingly brings about the death of an entire pod of whales, and only Siku survives. For this act, the boy receives a curse of banishment. Through the generations, this curse is handed down: Siku returns year after year, in reality and dreams, to haunt the boy’s descendants. Told in alternating voices, both human and whale, Jean Craighead George’s last novel shows the interconnectedness of humankind and the animals they depend on. “It’s a bold, wistful, and heartfelt coda to a distinguished career.”—School Library Journal

Download or read book Growth Morphology and Energetics of Bowhead Whales Balaena Mysticetus written by John C. George and published by . This book was released on 2009 with total page 336 pages. 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.

Download or read book Whales Dolphins Porpoises written by Annalisa Berta and published by University of Chicago Press. This book was released on 2015-10-15 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eighty-nine cetacean species that swim our seas and rivers are as diverse as they are intelligent and elusive, from the hundred-foot-long, two-hundred-ton blue whale to the lesser-known tucuxi, ginkgo-toothed beaked whale, and diminutive, critically endangered vaquita. The huge distances these highly migratory creatures cover and the depths they dive mean we catch only the merest glimpses of their lives as they break the surface of the water. But thanks to the marriage of science and technology, we are now beginning to understand their anatomy, complex social structures, extraordinary communication abilities, and behavioral patterns. In this beautifully illustrated guide, renowned marine mammalogist Annalisa Berta draws on the contributions of a pod of fellow whale biologists to present the most comprehensive, authoritative overview ever published of these remarkable aquatic mammals. Opening with an accessible rundown of cetacean biology—including the most recent science on feeding, mating, and communication—Whales, Dolphins, and Porpoises then presents species-specific natural history on a range of topics, from anatomy and diet to distribution and conservation status. Each entry also includes original drawings of the species and its key identifiers, such as fin shape and color, tooth shape, and characteristic markings as they would appear both above and below water—a feature unique to this book. Figures of myth and—as the debate over hunting rages on—figures of conflict since long before the days of Moby-Dick, whales, dolphins, and porpoises are also ecologically important and, in many cases, threatened. Written for general enthusiasts, emergent cetacean fans, and biologists alike, this stunning, urgently needed book will serve as the definitive guide for years to come.

Download or read book Biochemistry and Cell Biology of Ageing Part I Biomedical Science written by J. Robin Harris and published by Springer. This book was released on 2019-02-18 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume in the Subcellular Biochemistry series will focus on the biochemistry and cellular biology of aging processes in human cells. The chapters will be written by experts in their respective fields and will focus on a number of the current key areas of research in subcellular aging research. Main topics for discussion are mitochondrial aging, protein homeostasis and aging and the genetic processes that are involved in aging. There will also be chapters that are dedicated to the study of the roles of a variety of vitamins and minerals on aging and a number of other external factors (microbiological, ROS, inflammation, nutrition). This book will provide the reader with a state of the art overview of the subcellular aging field. This book will be published in cooperation with a second volume that will discuss the translation of the cell biology of aging to a more clinical setting and it is hoped that the combination of these two volumes will bring a deeper understanding of the links between the cell and the body during aging.
