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

Download or read book Indicator Plants of Coastal British Columbia written by A. Ceska and published by UBC Press. This book was released on 2011-11-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This original work makes unprecedented use of some of the most important research to date in plant ecology. It is a guide for assessing site quality, that is, the climate and soil of particular forest and non-forest ecosystems. Foresters have long been interested in using plants as indicators in predicting the growth performance of reforestation sites, but the data have not been readily available. Indicator Plants of Coastal British Columbia fully discusses how indicator plants are recognized and demonstrates how indicator plants can be used in site diagnosis. The book presents colour illustrations and descriptions of 419 selected vascular plants, bryophytes and lichens of coastal British Columbia. Indicators with similar values are grouped into indicator species groups which are used to evaluate site quality. These data are supplemented by information on geographic distribution, life-form, shade tolerance, and other ecological characteristics of the species. Three methods are given on how to use indicator plants for the purpose of site diagnosis. Indicator Plants of Coastal British Columbia summarizes original research in a format which both students and practitioners will find easy to use.

Download or read book Flora of the Pacific Northwest written by C. Leo Hitchcock and published by University of Washington Press. This book was released on 2018-09-17 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of the Pacific Northwest, first published in 1973, became an instant classic for its innovative style of providing species descriptions in the identification keys, and for its comprehensive illustrations of nearly all treated taxa (species, subspecies, and varieties). Students rely on it as an essential primer, while veteran botanists and natural resource managers use it as the definitive reference for the region�s flora. This completely revised and updated edition captures the advances in vascular plant systematics over the decades since publication of the first edition. These advances, together with significant changes in plant nomenclature, the description of taxa new to science from the region, and the recent documentation of new native and nonnative species in the Pacific Northwest required a thorough revision of this authoritative work. Flora of the Pacific Northwest covers all of Washington, the northern half of Oregon, Idaho north of the Snake River Plain, the mountainous portion of western Montana, and the southern portion of British Columbia. It accounts for the wild-growing native and introduced vascular plants falling within those boundaries and includes: Treatment of 5,545 taxa (more than 1,000 taxa added from the first edition) Illustrations for 4,716 taxa (1,382 more than the first edition) Nomenclature changes for more than 40 percent of the taxa included in the first edition These enhancements make this new edition the most comprehensive reference on Pacific Northwest vascular plants for professional and amateur botanists, ecologists, rare plant biologists, plant taxonomy instructors, land managers, nursery professionals, and gardeners.

Book excerpt: This richly illustrated text/reference, originally printed in 1985, provides a comprehensive introduction to the structure, evolution and interrelationships of the bryophytes. Leading bryologist W. B. Schofield gives a broad, international view of bryology that goes beyond a basic understanding of structure to present the bryophytes as a vital group of living plants. After a solid foundation in the morphology of mosses, liverworts and hornworts separate chapters, organized to allow easy comparison of the evolutionary lines, offer definitive information on the biology of the organisms. Topics covered in detail include cytology, genetics, chemistry, ecology, physiology, geography and the history of the discipline. Emphasizing the biologic significance of the bryophytes, the author uses an abundance of elegant original illustrations to show the structure, diversity and the natural beauty of the bryophytes. There is also an extensive glossary of bryologic terminology. W. B. Schofield is Professor Emeritus at the University of British Columbia in Vancouver. He is a former president of the American Bryological and Lichenological Society.

Download or read book Experimental Habitat Fragmentation and Simulation of Landscape Dynamics in the Boreal Mixedwood written by S. G. Cumming and published by . This book was released on 1995 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a study of about 74,000 square kilometres of mixedwood boreal forest in northern Alberta, with the main objective of acquiring, synthesising, and applying information on the response of the forest to broad-scale timber harvesting. Study methodology involved analysis of landscape patterns and species-specific population attributes in the area, followed by development of a model of landscape dynamics including components of vegetation zonation, successional change, and disturbance regimes (notably fire). The model includes a new, non-spatial fires history model developed from provincial fire history data. Simulation of the effects of logging in the study area was performed by TARDIS, a specially developed spatial harvest schedule simulator. A sub-project of the study involved an experimental study of how forest fragmentation induced by timber harvesting affects the community and population dynamics on non-game birds in aspen-dominated forest. In the experiment, fragments of old mixedwood forest, from one to 100 hectares in size, were isolated from adjacent forest and bird populations documented before and after isolation. A correlation matrix revealed relationships between bird species densities and habitat variables. Concludes with a systematic comparison of three spatial forest inventory data sets which revealed discrepancies in estimated forest composition.
