Download or read book Birds of Ontario Habitat Requirements Limiting Factors and Status written by Al Sandilands and published by UBC Press. This book was released on 2011-01-01 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volumes in the Birds of Ontario series summarize life history requirements of bird species that are normally part of the ecology of Ontario. This is the second volume in the series and completes the treatment of the nonpasserine bird species occurring in Ontario on a regular basis. Information on habitat, limiting factors, and status is summarized for 83 species in this volume. These topics are covered for the three primary avian seasons: breeding, migration, and winter. Habitat, nest sites, territoriality, site fidelity, annual reproductive effort, habitat loss and degradation, environmental contaminants, and a variety of other topics are covered in the species accounts. Maps depicting breeding and wintering range are presented for most species along with drawings by Ross James. Birds of Ontario is an essential reference source for wildlife biologists, environmental consultants, and planners preparing or reviewing environmental impact statements and environmental assessments. Serious birders will find the volumes of interest as well. Although the books focus on Ontario birds, the information is highly relevant to adjacent provinces and states.

Hughes and published by [Downsview, Ont.] : Canadian Wildlife Service. This book was released on 2006 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The numerous islands and extensive shoreline of Lake Huron support a wide diversity and abundance of aquatic wildlife. This report examines the current status, trends and distributions of aquatic populations of colonial waterbirds, waterfowl, birds of prey, amphibians, reptiles and fish-eating mammals such as mink and otter on the Canadian shores of Lake Huron. The status of habitat, including coastal wetlands, for some of these species is also reviewed"--Exec. summary.

Download or read book Persistent Organic Pollutants in the Great Lakes written by Ronald A. Hites and published by Springer. This book was released on 2010-10-19 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollution threatens the Laurentian Great Lakes and is a serious problem. This book examines what is known about the major classes of persistent toxic organic pollutants. Agricultural runoff, urban waste, industrial discharge, landfill leachate, and atmospheric deposition, are all to blame. Contamination of the various ecosystems is reviewed, and what is known about the effects of this pollution. This volume provides an invaluable resource for those in environmental research, measurements, and decision making concerning the Great Lakes.

Download or read book Ecological Risk Assessment written by Glenn W. Suter II and published by CRC Press. This book was released on 1992-10-23 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

Download or read book A Risk Management Strategy for PCB Contaminated Sediments written by National Research Council and published by National Academies Press. This book was released on 2001-06-07 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a risk-based framework for developing and implementing strategies to manage PCB-contaminated sediments at sites around the country. The framework has seven stages, beginning with problem definition, continuing through assessment of risks and management options, and ending with an evaluation of the success of the management strategy. At the center of the framework is continuous and active involvement of all affected parties-particularly communities-in the development, implementation, and evaluation of the management strategy. A Risk-Management Strategy for PCB-Contaminated Sediments emphasizes the need to consider all risks at a contaminated site, not just human health and ecological effects, but also the social, cultural, and economic impacts. Given the controversy that has arisen at many PCB-contaminated sites, this book provides a consistent, yet flexible, approach for dealing with the many issues associated with assessing and managing the risks at Superfund and other contaminated sites.

Download or read book Lipids in Freshwater Ecosystems written by Michael T. Arts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental purpose of this book is to synthesise the divergent literature on aquatic lipids into a co-ordinated, digestible form. A large part of the book addresses lipid composition and production in freshwater organisms, with chapters on phytoplankton, zooplankton and benthic invertebrates. A common theme throughout the book is the function of lipids in aquatic food webs, with a chapter devoted exclusively to lipids as indicators of health in fish populations. A complementary chapter highlights the role of lipids and essential fatty acids in mariculture. Methodologies to determine the lipid content of aquatic samples and suggestions as to the utility of fatty acids as trophic markers are included, as is one chapter on the role of lipids in the bioaccumulation and bioconcentration of toxicants and another on the relationships between lipids and surface films and foams. The final chapter highlights the similarities and differences between lipids of marine and freshwater origin. Students and researchers in ecology, phycology, aquatic toxicology, physiological ecology and limnology will find this an invaluable guide and reference.
