This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: "We provide a spatial and temporal description of the habitats important to the conservation of North Atlantic right whales (Eubalaena glacialis) in US waters of the Northwest Atlantic Ocean. This analysis is based on the premise that the biological and physical feature of habitat essential to the conservation of right whales in this region (i.e., the primary constituent element [PCE] which a species needs to survive and reproduce) is the presence of dense patches of calanoid copepods (notably Calanus finmarchicus). Despite the general importance of copepods to the marine food web of the region, only limited data are available to map the distribution of dense copepod patches that constitute the PCE for foraging right whales. Hence, we used right whale foraging areas as a proxy for the spatial locations of these patches. Based on systematic sighting surveys for right whales conducted from 1970 through 2005, we identified concentrations of foraging right whales in US Atlantic waters north of 40° N latitude. These data were then used to define Dynamic Area Management (DAM) zones, which indicated that most of the area north of the Great South Channel on Georges Bank was used at least seasonally for foraging. This region included seasonal foraging subareas generally identified as Cape Cod Bay, Great South Channel, Northern Edge of Georges Bank, Western Gulf of Maine, Wilkinson Basin, and Jordan Basin. Wilkinson and Jordan Basins are also considered essential to the conservation of right whales because these two basins are source areas for the dense copepod concentrations upon which right whales prey in US Northwest Atlantic waters"--Publication's home page.

Available in PDF, EPUB and Kindle. Book excerpt: Intense whaling nearly abolished the North Atlantic right whale (Eubalaena glacialis) population. Present day threats to the species are collisions with vessels, entanglement in fishing gear, and environmental variability. In this body of work we quantify the relationship between right whales and their prey, ricegrain sized crustaceans called copepods, and employ a spatial model to predict the potential distribution of right whales on a weekly basis. Time series datasets of right whale abundance and copepod concentration were analyzed to quantify the relationship between right whales and their prey. We found significant relationships between right whales and copepods in Cape Cod Bay and the Great South Channel. These results tell us that accurate regional-scale models of copepod concentration can be used to infer the time and location of good right whale feeding conditions. The environmental niche of right whales was characterized using modeled prey abundance, sea surface temperature, chlorophyll concentration and bathymetry. With environmental data for the time and location of each right whale occurrence between 2002 and 2006, we trained and tested a model to predict right whale habitat suitability on a weekly basis. The accuracy of predictions was good, and the feasibility of our approach was verified. Results suggest that right whale habitat preferences are dynamic and that the distribution of prey is an important to the distribution of whales. We built an operational forecasting model of right whale habitat suitability in Cape Cod Bay, and used it to make weekly predictions for the year 2009. Modeled concentration of two right whale prey taxa (C. finmarchicus and Pseudocalanus spp.) sea surface temperature, chlorophyll and bathymetry were used as predictor variables. Predictions were verified with occurrences of right whales in Cape Cod Bay from 2009. Model output was used to assess the utility of moving shipping routes in Cape Cod Bay. The model was then projected, beyond the model-training region, into Massachusetts Bay. Results suggested that altering of shipping lanes in Cape Cod Bay is unlikely to reduce the risk of ship-strikes. A significant positive relationship was found between predicted habitat suitability and the number of acoustic detections of right whales in Massachusetts Bay. We conclude that our modeling approach could be used to: 1) issue weekly forecasts of right whale habitat quality, 2) assess conservation actions, 3) guide survey effort in other regions, and ultimately to reduce human-caused risk to the right whales.

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: In the cold waters of the North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species--the North Atlantic right whale. This book is a history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon.

Available in PDF, EPUB and Kindle. Book excerpt: "Marine scientist Michael J. Moore says we are all whalers, but we don't have to be. Eating fish leads to North Atlantic right whales' entanglement and death. Buying goods made around the world requires global shipping routes, which do not accurately consider right whale breeding and feeding sites, leading to collision. To explain this, Moore conveys to readers scenes from over thirty years' worth of fieldwork, performing whale necropsies for animals stranded on beaches, working as an independent researcher alongside whalers using explosive harpoons, and tracking injured pregnant whales to deliver antibiotics. Despite these sometimes disturbing experiences, Moore has written a hopeful book. He uses these stories to show we can change and to tell us how; the technology for rope-less fishing and tracking whale migrations already exist to protect both right whales and the people who depend on shipping and fishing for their livelihoods"--
Download or read book Spatial Ecology of the North Atlantic Right Whale Eubalaena Glacialis written by Caroline Paddock Good and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite decades of protection, the endangered North Atlantic right whale (Eubalaena glacialis) has failed to recover, primarily due to interactions with fishing gear and ship strikes. Right whales range along the U.S. east coast, foraging year round in the Gulf of Maine while a subset of the population travels to the South Atlantic Bight each year to calve. The habitat requirements of the right whale are poorly understood. I investigated the relationship between the distribution of right whales and physical oceanographic conditions in an effort to create predictive models of essential right whale habitats. Additionally, the distribution of right and humpback whales (Megaptera novaeangliae) relative to fixed fishing gear was examined to assess spatio-temporal overlap. Habitat preferences were assessed using aerial survey data of whale locations and a range of topological and satellite derived physical parameters including bathymetry, sediment type, sea surface temperature, thermal gradients and surface roughness. A suite of non-parametric quantitative techniques including Mantel tests, log likelihood functions, Generalized Additive Models, Spearman Rank Correlations and the Williamson's spatial overlap index were used to assess relationships between whales and habitat variables. Our findings indicate that suitable calving habitat along the east coast may extend much farther to the north than is currently recognized. Our model correctly identified several well documented current and historic calving grounds in the eastern Atlantic but failed to fully identify a heavily used calving area off Argentina, which is characterized by lower surface water temperatures than the other calving regions. In the Gulf of Maine, right whale distribution was correlated primarily with sea surface temperature, sediment type and bathymetry. Predictive models offered insights into right whale habitat preferences for foraging but failed to wholly capture the physical factors underlying right whale distribution. I found the relative density of right and humpback whales and fixed fishing gear in the Gulf of Maine to be negatively correlated in most seasons and areas. These findings demonstrate that the regular co-occurrence of high densities of whales and gear is not a prerequisite for entanglement. Prohibiting entangling lines in areas where whales are known to forage could substantively reduce entanglement.

Available in PDF, EPUB and Kindle. Book excerpt: The fascinating story of North Atlantic right whales—from their evolutionary origin, through a thousand-year history of relentless pursuit by whalers, to ongoing efforts to rescue them from the brink of extinction. In the cold waters of the unforgiving North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people on both sides of the Atlantic became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species—the North Atlantic right whale. Conservationist David W. Laist now provides the first complete history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon. Favored by whalers because of their high yields of oil and superior baleen, these giants became known as "the right whale to hunt," and their numbers dwindled to a mere 100 individuals worldwide. Their dire status encouraged the adoption of a ban on hunting and a treaty that formed the International Whaling Commission. Recovery of the species, however, has proven elusive. Ship strikes and entanglement in commercial fishing gear have hampered herculean efforts to restore the population. Today, only about 500 right whales live along the US and Canadian Atlantic coasts—an improvement from the early twentieth century, but still a far cry from the thousands that once graced Atlantic waters. Laist's masterpiece features an incredible collection of photographs and artwork that give life to the fascinating history that unfolds in its pages. The result is a single volume that offers a comprehensive understanding of North Atlantic right whales, the role they played in the many cultures that hunted them, and our modern attempts to help them recover.
