Book Synopsis Patterns of Fishing Gear in Areas of the Bay of Fundy and Southwest Scotian Shelf Frequented by North Atlantic Right Whales by : Terry L. Johnston
Download or read book Patterns of Fishing Gear in Areas of the Bay of Fundy and Southwest Scotian Shelf Frequented by North Atlantic Right Whales written by Terry L. Johnston and published by . This book was released on 2007 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: North Atlantic right whales (Eubalaena glacialis) are among the most critically endangered cetacean species in the world. Despite having protected status, both internationally and in Canadian waters, the right whale population that frequents Canadian waters remains at low abundance, with an estimated population of around 325 individuals (EC 2006). It has been estimated that at least thirty percent of right whale deaths result from their interaction with human activities, and entanglement in fishing gear is a significant cause for known injury and mortality (Knowlton and Kraus 2001). This report has identified the different gear types and fisheries that right whales encounter in Scotia-Fundy region, as well as the potential they pose for entanglement. Commercial landings data for the time series between 1999 and 2005 inclusive were used to assess the spatial and temporal distribution of fishing activity. These fishery distributions were compared to the patterns of right whale aggregation in Scotia-Fundy waters in order to estimate the potential for right whale/gear interaction among the different gear types/fisheries over time and space. Of all the gears that right whales encounter in their summer habitat, the groundfish gillnet, groundfish hook and line, and crab trap fisheries pose the greatest potential for entanglement. These gear types are relatively more likely to lead to entanglement because (1) these are the most active fisheries in Scotia-Fundy during the period of right whale aggregation, and (2) the design of the gears and their methods of deployment lend themselves to possible entanglements. The results of this study may be used to advise industry and management on actions that would minimize the risk of entanglement to right whales, while correspondingly minimizing any disruption of the commercial fisheries in the Scotia-Fundy region

Book Synopsis Politics of the Wild by : Karen Beazley
Download or read book Politics of the Wild written by Karen Beazley and published by Don Mills, Ont. : Oxford University Press. This book was released on 2001 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Politics of the Wild details the 353 species at risk in Canada and considers both the intrinsic and the instrumental reasons for protecting biological diversity. It examines the need for habitat protection, terrestrial protected areas such as national parks, marine species at risk, and the various legislative and interest group attempts to preserve biodiversity. Public policy on endangered species is considered from both historical and comparative perspectives, as is Canada's role in establishing international agreements--the Convention on International Trade in Endangered Species and the Convention on Biological Diversity--and the government's failure in recent years to meet the obligations of these and other environmental agreements. The final chapter looks at the Species at Risk Act (SARA) and its recent predecessor, Bill C-65, and reveals the difficulties of crafting and passing such legislation in an increasingly decentralized federal state such as Canada. Both legislative attempts were criticized--by the environmental policy community for not doing enough, and by the provinces and business for trying to do too much. All the while, diverse regional interests and economic imperatives run the risk of endangering far more than merely Canadian species at risk.

Available in PDF, EPUB and Kindle. Book excerpt: In 1980 a group of scientists censusing marine mammals in the Bay of Fundy was astonished by the sight of 25 right whales. 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.
Book Synopsis The Gray Whale: Eschrichtius Robustus by : Mary Lou Jones
Download or read book The Gray Whale: Eschrichtius Robustus written by Mary Lou Jones and published by Academic Press. This book was released on 2012-12-02 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.

It launches a new chapter in cetacean conservation with its investigation into the crucial habitat needs and protection requirements of some 84 species.The author, one of the world's foremost experts in this field, takes you around the world to investigate the promising results of the latest conservation research and the strategies for obtaining marine protected areas in coastal waters and on the high seas, using national legislation and regional and international conventions. This is an essential introduction, guide and reference work for those working to ensure a future for whales and dolphins.
Book Synopsis Global Change in Marine Systems by : Patrice Guillotreau
Download or read book Global Change in Marine Systems written by Patrice Guillotreau and published by Routledge. This book was released on 2017-11-13 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Change in Marine Systems analyses and appraises societal and governing responses to change affecting marine social and ecological systems around the world. Acknowledging the stakes – local societies that depend on marine systems for food, livelihoods and wellbeing can suffer great hardship – this book highlights and explains similarities and distinctions between successful and unsuccessful responses. The book presents an analytical framework (‘I-ADApT’) that enables decision-makers to consider possible responses to global change based on experiences elsewhere. Here an international group of researchers from the natural and social sciences apply the ‘I-ADApT’ framework to twenty enlightening case studies, covering a wide range of marine systems challenged by critical global change issues around the world. The innovative research presented here guides marine system researchers, policymakers, decision-makers and practitioners in responding to global change in a timely and appropriate manner. It will appeal to students and researchers interested in environmental studies, natural resources, marine resources, environmental sociology, sustainability, and climate change.

Book Synopsis Recording Structures of Mammals by : Galina A. Klevezal
Download or read book Recording Structures of Mammals written by Galina A. Klevezal and published by CRC Press. This book was released on 1995-06-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text focuses on the principles and methods of using growth layers formed in teeth and bones of mammals to make a judgement on essential traits of the animal's life history. In nearly all mammalian species, including man, the age of individuals can be determined from the number of growth layers and, at least in some of them, it is possible to estimate the season of an animal's birth and death, age of sexual maturation, periodicity of reproduction, certain feeding habits and other aspects of the individual's biology. It is also possible, from tooth-enamel analysis, to assess doses of radiation accumulated by animals and human beings during their lifetime.;This book is intended for zoologists, wild-game biologists and zoo archaeologists, but some of the sections could also be of interest for anthropologists, radioecologists and conservation biologists.
