This book was released on 1992 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The western North Atlantic population of the northern right whale (Eubalaena glacialis) was severely depleted by whaling over the last century. Despite over fifty years of protection, fewer than four hundred individuals are believed to exist in the North Atlantic. Relatively little is known about the diving behavior, respiratory physiology, or diel activity of these whales, although such information could be useful in predicting population abundance and distribution in relation to food or environmental variables. Dive behavior data can be collected visually, but collection is limited to daylight hours, calm weather, and fortuitous encounters with study animals. Satellite-monitored radio tags offer the opportunity to collect data on individual whales' diving behavior continuously, over long distances and periods of time, and at relatively low cost. Thirteen North Atlantic right whales were tagged and monitored in the Gulf of Maine between 1989 and 1991. One male was tagged in 1989; two adult males, six adult females (two with calves) and one juvenile were tagged in 1990; one adult female (with a calf) and two juveniles were tagged in 1991. The duration of monitoring for the whales varied from

Available in PDF, EPUB and Kindle. Book excerpt: In 1980 a group of scientists censusing marine mammals in the Bay of Fundy was astonished at the sight of 25 right whales. It was, one scientist later recalled, "like finding a brontosaurus in the backyard." Until that time, scientists believed the North Atlantic right whale was extinct or nearly so. The sightings electrified the research community, spurring a quarter century of exploration, which is documented here. The authors present our current knowledge about the biology and plight of right whales, including their reproduction, feeding, genetics, and endocrinology, as well as fatal run-ins with ships and fishing gear. Employing individual identifications, acoustics, and population models, Scott Kraus, Rosalind Rolland, and their colleagues present a vivid history of this animal, from a once commercially hunted commodity to today's life-threatening challenges of urban waters. Hunted for nearly a millennium, right whales are now being killed by the ocean commerce that supports our modern way of life. This book offers hope for the eventual salvation of this great whale.

Available in PDF, EPUB and Kindle. Book excerpt: The ecology of the North Atlantic right whale (Eubalaena glacialis) was examined at three spatial scales during the summer and early fall on their northern feeding grounds. The diving and foraging behavior of right whales was investigated at spatial scales of hundreds to thousands of meters by tagging right whales with time-depth recorders to document their diving behavior. The vertical distributions of temperature, salinity and copepods were measured along the tagged whale's track with a conductivity-temperature-depth instrument (CTD) and an optical plankton counter (OPC). Right whales were observed diving to and presumably feeding on discrete layers of their primary prey. older stages of the calanoid copepod Calanus finmarchicus, aggregated just above the bottom mixed layer. Simultaneous visual and oceanographic surveys conducted in the lower Bay of Fundy and Roseway Basin were used to examine right whale distribution at spatial scales of tens of kilometers. Right whale occurrence was associated with greater depths and thicker bottom mixed layers in these regions. There was additional evidence of an association between right whales and ocean fronts in Roseway Basin. Right whale distribution was also examined on spatial scales of hundreds of kilometers by outfitting whales with satellite-monitored radio tags. Movements of the tagged whales were compared to climatological and remotely-sensed environmental datasets to elucidate habitat preferences. The tagged whales moved extensively throughout the Gulf of Maine and western Scotian Shelf where they frequented shallow basins with cold bottom waters, but avoided deep, comparatively warmer basins. Two of the right whale ecology studies described here depended on the OPC for measures of right whale prey distribution and abundance. A final study was conducted to investigate the response of the OPC to C. finmarchicus copepodite stage 5 (CS). Comparisons between collocated OPC casts and zooplankton net samples indicated that the OPC was adept at detecting C. finmarchicus C5. A calibration equation was developed to predict C. finmarchicus C5 abundance from OPC-derived particle abundance.

Book excerpt: This comprehensive book provides new insights into the morphological, metabolic, thermoregulatory, locomotory, diving, sensory, feeding, and sleep adaptations of Cetacea (whales and dolphins), Pinnipedia (seals, sea lions and walrus), Sirenia (manatees and dugongs) and sea otters for an aquatic life. Each chapter reviews the discoveries from previous studies and integrates recent research using new techniques and technology. Readers will gain an understanding of the remarkable adaptations that enable marine mammals to spend all or most of their lives at sea, often while hunting prey at depth.
