The Biodiversity Atlas of British Columbia


Book Description

With sixty descriptive maps and accompanying text, The Biodiversity Atlas of British Columbia provides a broad overview of the province?s range of terrestrial and freshwater biological diversity. Bringing together data from numerous sources summarized in map form, the Atlas provides a window to B.C.?s diverse ecosystems, the species that live in them, and the elements of British Columbia?s biodiversity that make it globally significant. The Atlas also presents a visual perspective of a number of human-induced threats, including climate change, affecting biodiversity in B.C. today. The Atlas is designed to serve as a companion document to Taking Nature?s Pulse: The Status of Biodiversity in British Columbia ? a comprehensive scientific assessment of biodiversity in the province. Both the Atlas and Taking Nature?s Pulse are projects of Biodiversity BC, a partnership of conservation groups and government agencies.




How to Build Social Science Theories


Book Description

Click ′Additional Materials′ to read the foreword by Jerald Hage As straightforward as its title, How to Build Social Science Theories sidesteps the well-traveled road of theoretical examination by demonstrating how new theories originate and how they are elaborated. Essential reading for students of social science research, this book traces theories from their most rudimentary building blocks (terminology and definitions) through multivariable theoretical statements, models, the role of creativity in theory building, and how theories are used and evaluated. Authors Pamela J. Shoemaker, James William Tankard, Jr., and Dominic L. Lasorsa intend to improve research in many areas of the social sciences by making research more theory-based and theory-oriented. The book begins with a discussion of concepts and their theoretical and operational definitions. It then proceeds to theoretical statements, including hypotheses, assumptions, and propositions. Theoretical statements need theoretical linkages and operational linkages; this discussion begins with bivariate relationships, as well as three-variable, four-variable, and further multivariate relationships. The authors also devote chapters to the creative component of theory-building and how to evaluate theories. How to Build Social Science Theories is a sophisticated yet readable analysis presented by internationally known experts in social science methodology. It is designed primarily as a core text for graduate and advanced undergraduate courses in communication theory. It will also be a perfect addition to any course dealing with theory and research methodology across the social sciences. Additionally, professional researchers will find it an indispensable guide to the genesis, dissemination, and evaluation of social science theories.




Current Ornithology


Book Description

This is the only English-language publication devoted exclusively to extensive reviews and synthesis of topics on the biology of birds. The current volume includes articles on sibling competition, predation and the limitation of bird numbers, and population trends in birds of eastern North America.







Ecological Impact Assessment


Book Description

The world's ecosystems are increasingly threatened by human development. Ecological impact assessment (EcIA) is used to predict and evaluate the impacts of development on ecosystems and their components,thereby providing the information needed to ensure that ecological issues are given full and proper consideration in development planning. Environmental impact assessment (EIA) has emerged as a key to sustainable development by integrating social, economic and environmental issues in many countries. EcIA has a major part to play as a component of EIA but also has other potential applications in environmental planning and management. Ecological Impact Assessment provides a comprehensive review of the EcIA process and summarizes the ecological theories and tools that can be used to understand, explain and evaluate the ecological consequences of development proposals. It is intended for the many individuals and companies involved in EIA and EcIA, as well as other areas of environmental management where impacts on ecosystems need to be evaluated. It will benefit planners, regulators, environmental consultants and scientists and will also provide an invaluable sourcebook and guide for the growing number of undergraduate students taking courses in applied ecology, EIA and related topics in environmental science. A practical management guide for the increasing numbers of practitioners of EcIA. A rapidly expanding subject driven by the proliferation of environmental legislation worldwide.




Species at Risk


Book Description

Protecting endangered species of animals and plants is a goal that almost everyone supports in principle—but in practice private landowners have often opposed the regulations of the Endangered Species Act, which, they argue, unfairly limits their right to profit from their property. To encourage private landowners to cooperate voluntarily in species conservation and to mitigate the economic burden of doing so, the government and nonprofit land trusts have created a number of incentive programs, including conservation easements, leases, habitat banking, habitat conservation planning, safe harbors, candidate conservation agreements, and the "no surprise" policy. In this book, lawyers, economists, political scientists, historians, and zoologists come together to assess the challenges and opportunities for using economic incentives as compensation for protecting species at risk on private property. They examine current programs to see how well they are working and also offer ideas for how these programs could be more successful. Their ultimate goal is to better understand how economic incentive schemes can be made both more cost-effective and more socially acceptable, while respecting a wide range of views regarding opportunity costs, legal standing, biological effectiveness, moral appropriateness, and social context.







COSEWIC Assessment and Status Report on the Enos Lake Benthic and Limnetic Threespine Stickleback Species Pair Gasterosteus Aculeatus in Canada


Book Description

Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status reports are working documents used in assigning the status of wildlife species suspected of being at risk. This document includes both an assessment and status report on the Enos Lake benthic and limnetic threespine stickleback species pair (Gasterosteus aculeatus) in Canada. It includes species information, distribution, habitat, and biology information, as well as population sizes and trends, limiting factors and threats, special significance of the species, and existing protection or other status.--Includes text from document.
