Download or read book The Subjugation of Canadian Wildlife written by Max Foran and published by McGill-Queen's Press - MQUP. This book was released on 2018-04-10 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly a day goes by without news of the extinction or endangerment of yet another animal species, followed by urgent but largely unheeded calls for action. An eloquent denunciation of the failures of Canada's government and society to protect wildlife from human exploitation, Max Foran's The Subjugation of Canadian Wildlife argues that a root cause of wildlife depletions and habitat loss is the culturally ingrained beliefs that underpin management practices and policies. Tracing the evolution of the highly contestable assumptions that define the human–wildlife relationship, Foran stresses the price wild animals pay for human self-interest. Using several examples of government oversight at the federal, provincial, and territorial levels, from the Species at Risk Act to the Biodiversity Strategy, Protected Areas Network, and provincial management plans, this volume shows that wildlife policies are as much – or more – about human needs, priorities, and profit as they are about preservation. Challenging established concepts including ecological integrity, adaptive management, sport hunting as conservation, and the flawed belief that wildlife is a renewable resource, the author compels us to recognize animals as sentient individuals and as integral components of complex ecological systems. A passionate critique of contemporary wildlife policy, The Subjugation of Canadian Wildlife calls for belief-change as the best hope for an ecologically healthy, wildlife-rich Canada.

Download or read book Chemical Contaminants in Canadian Aquatic Ecosystems written by D. M. Whittle and published by Canadian Government Publishing. This book was released on 1998 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on those chemicals that persist in the Canadian environment and that are accumulated by aquatic organisms. It summarizes scientific information collected previously, with emphasis on Canadian research findings published in the last decade. The first part of the report introduces the general features of aquatic ecosystems and provides basic information on the fate and effects of chemical contaminants. The second part reviews contaminant related issues for the following geographic areas: Atlantic marine ecosystems including the St. Lawrence, Bay of Fundy, and general north-west Atlantic; freshwater ecosystems including the Great Lakes and inland waters; the Arctic marine ecosystem; and Pacific aquatic ecosystems including the British Columbia coastal ecosystem, the open coast, and some of the major rivers. All chapters discuss the major contaminant issues, important oceanographic or limnological features, biological resources, and sources of contaminants as well as contaminant trends, distribution, and effects. Current and emerging chemical contaminant issues and associated research topics are summarized at the end of each chapter. The third part is an overall assessment of current knowledge of chemical contaminants and their effects on fish and fish habitat, and identifies major current and emerging contaminant issues confronting Canada's fish and fish habitat.

Download or read book Estimating Gulf of Maine Zooplankton Distributions Using Multiple Frequency Acoustic Video and Environmental Data written by Joseph David Warren and published by . This book was released on 2001 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis develops methods useful for estimating zooplankton distributions in the field by combining acoustic scattering models and an integrated set of field data. The accuracy of existing scattering models for fluid-like and elastic-shelled animals is determined by analysis of scattering data from individual animals in a laboratory tank. Results indicate that simple two-ray scattering models are accurate and allow predictions of size or orientation of an animal to be made for certain animal orientations. A scattering model for gas-bearing zooplankton is compared with in situ multiple frequency acoustic measurements from siphonophores. Estimates of the numerical density of these animals are made using echo integration data from a scientific echo-sounder. Multiple frequency acoustic scattering data from a survey of an internal wave are analyzed to determine the contributions from biological and physical sources. Net tow data provide information about biological scatterers while temperature and salinity profiles are used with a theoretical scattering model to predict contributions from physical sources. Results indicate that scattering from physical sources is comparable to that from biological sources in certain regions and that scattering spectra may be used to distinguish these sources. Improved estimates of biomass from acoustic scattering data were made by accounting for the scattering contributions from physical sources. This is the first work to quantify the scattering contributions from biological and physical sources of scattering in a field study.
