Abstract: Habitat is now the basis of most impact assessments and resource inventories, and it is the basis of many species management plans, mitigation planning, and environmental regulation. Habitats are relatively stable through time, easily defined in intuitive physical terms, and provide a tangible resource for negotiations and decision making. Numerous and varied methods of analyzing and reporting habitat conditions have been developed by federal, state, provincial, and private agencies. Habitat assessment approaches vary greatly among regions of the continent. The great variability in methods and an unusually wide range of practices have impeded the ability of agencies to share and synthesize information. A diversity of methods is desirable in the initial stages of a rapidly developing field, but enough time has passed to assess the state-of-knowledge and identify the best of the currently used methods and techniques. This manual is intended to provide fisheries biologists with a limited set of techniques for obtaining aquatic habitat data. The manual also describes the range of information collected and used in agency habitat analyses. Agencies planning habitat programs should review the synthesis of established and documented methods being used in North America (Appendix 1) and the planning recommendations in Chapter 2. Then, the remaining chapters should be reviewed to determine what types of habitat data should be included in the agency's program.
The existence of the human race has created inevitable effects on our surrounding environment. To prevent further harm to the world’s ecosystems, it becomes imperative to assess mankind’s impact on and create sustainability initiatives to maintain the world’s ecosystems. Climate Change and Environmental Concerns: Breakthroughs in Research and Practice is a comprehensive reference source for the latest scholarly material on the environmental effects of climate change on human health, and the mitigation of climate change on both a local and global level. Highlighting a range of pertinent topics, such as sustainable land use, greenhouse gas effects, and environmental education, this publication is ideally designed for policy makers, professionals, government officials, upper-level students, and academics interested in emerging research on climate change.
Research inherently requires collaborative efforts between individuals, databases, and institutions. However, the systems that enable such interpersonal cooperation must be properly suited in facilitating such efforts to avoid impeding productivity. Collaborative Knowledge in Scientific Research Networks addresses the various systems in place for collaborative e-research and how these practices serve to enhance the quality of research across disciplines. Covering new networks available through social media as well as traditional methods such as mailing lists and forums, this publication considers various scientific disciplines and their individual needs. Theorists of collaborative scientific work, technology developers, researchers, and funding agency officials will find this book valuable in exploring and understanding the process of scientific collaboration.
Provides an evaluative, narrative introduction, international in scope, to the position and usefulness of the principal sources of information on the subject of environmental protection. The volume's four sections cover government policies and pressure groups; the effects of the exploitation of natu
*Comprehensive discussion of environmental stressors affecting aquatic ecosystems and organisms *Contributions from leading scientists in the field *Practical manual for students and researchers on the use of biocriteria *A practical guide to the use of biocriteria for assessment of the effects of environmental stressors on aquatic ecosystems and organisms, especially fish. Written by scientists who are experts in their fields, this book provides helpful information for designing and applying bioindicators in the field to reliably assess the health of aquatic organisms and ecosystems. This volume may be used as a manual for scientists, students, and others, in a variety of disciplines and applications
