Book excerpt: 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.
Download or read book Land Snails of British Columbia written by Robert G. Forsyth and published by . This book was released on 2004 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Snails and slugs have a reputation as slimy, repulsive creatures that are nothing more than garden pests, but they are important components of the ecosystems they live in. In fact, most of the pest slugs and snails are introduced species that have come here with the plants we import for our gardens. Worldwide there are more species of snails and slugs than all the mammals, birds, reptiles and amphibians combined, yet they are often overlooked because of their relatively small size. Land snails and slugs are well adapted to live in almost any kind of environment, from high arctic tundra to tropical forests. In British Columbia, they can be found just about everywhere. Land Snails of British Columbia describes all 92 species of terrestrial molluscs in our province. It includes photographs and detailed drawings of each, diagnostic keys and a selection of colour photographs to aid in identification. With each species description, the author discusses its natural history and distribution in the province. He also talks about reproduction, life history, diet, locomotion and shell structure (even slugs have shells). Nature buffs and anyone interested in looking past the bad reputation of these much-maligned creatures will find this handbook an enlightening guide. For gardeners, this book will tell you which snails to cast out of your garden and which ones to keep, because some snails and slugs are beneficial to gardens and some even prey on their pestilent relatives."--

Book excerpt: The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic. This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies. - Provides succinct overviews of the biology of the Atlantic Walrus (Odobenus rosmarus rosmarus) as well as human cultures within the North Atlantic Arctic and the surrounding region by consolidating research which until now has been scattered across fields and academic publications - Editorial team of inter-disciplinary researchers ensuring the breadth, depth and integration of material covered throughout the volume - Thirteen chapters, each authored by leading international researchers and experts on the Atlantic Walrus - Considers the inter-relatedness and complexity of species biology, ecological change, human culture, and anthropogenic pressures onto the Atlantic Walrus, all while remaining accessible to readers from different disciplines or a more generalist audience - Draws upon the latest methods in marine mammal and archaeological research - Assesses historical management of the species, while also considering current and future conservation efforts in light of human activities and climate change - Text supported by striking and insightful new maps and scientific illustrations, ideal for teaching and outreach
