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."--

Download or read book Temperate and Boreal Rainforests of the World written by Dominick A. DellaSala and published by Island Press. This book was released on 2011 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate rainforests are biogeographically unique. Compared to their tropical counterparts, temperate rainforests are rarer and are found disproportionately along coastlines. Because most temperate rainforests are marked by the intersection of marine, terrestrial, and freshwater systems, these rich ecotones are among the most productive regions on Earth. Globally, temperate rainforests store vast amounts of carbon, provide habitat for scores of rare and endemic species with ancient affinities, and sustain complex food-web dynamics. In spite of their global significance, however, protection levels for these ecosystems are far too low to sustain temperate rainforests under a rapidly changing global climate and ever expanding human footprint. Therefore, a global synthesis is needed to provide the latest ecological science and call attention to the conservation needs of temperate and boreal rainforests. A concerted effort to internationalize the plight of the world’s temperate and boreal rainforests is underway around the globe; this book offers an essential (and heretofore missing) tool for that effort. DellaSala and his contributors tell a compelling story of the importance of temperate and boreal rainforests that includes some surprises (e.g., South Africa, Iran, Turkey, Japan, Russia). This volume provides a comprehensive reference from which to build a collective vision of their future.

Download or read book Critical Loads and Dynamic Risk Assessments written by Wim de Vries and published by Springer. This book was released on 2015-04-20 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unique overview of research methods over the past 25 years assessing critical loads and temporal effects of the deposition of air pollutants. It includes critical load methods and applications addressing acidification, eutrophication and heavy metal pollution of terrestrial and aquatic ecosystems. Applications include examples for each air pollution threat, both at local and regional scale, including Europe, Asia, Canada and the US. The book starts with background information on the effects of the deposition of sulphur, nitrogen and heavy metals and geochemical and biological indicators for risk assessments. The use of those indicators is then illustrated in the assessment of critical loads and their exceedances and in the temporal assessment of air pollution risks. It also includes the most recent developments of assessing critical loads and current and future risks of soil and water chemistry and biodiversity under climate change, with a special focus on nitrogen. The book thus provides a complete overview of the knowledge that is currently used for the scientific support of policies in the field of air pollution control to protect ecosystem services.

Download or read book The Earth as Transformed by Human Action written by B. L. Turner and published by Cambridge University Press. This book was released on 1993-01-29 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth as Transformed by Human Action is the culmination of a mammoth undertaking involving the examination of the toll our continual strides forward, technical and social, take on our world. The purpose of such a study is to document the changes in the biosphere that have taken place over the last 300 years, to contrast global patterns of change to those appearing on a regional level, and to explain the major human forces that have driven these changes. The first section deals strictly with the major human forces of the past 300 years and the second is a detailed account of the transformations of the global environment wrought by human action. The final section examines a range of perspectives and theories that purport to explain human actions with regard to the biosphere.

Download or read book Treatise on Geomorphology written by and published by Academic Press. This book was released on 2013-02-27 with total page 6392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!
