Download or read book EcoRegions of Alaska written by Alisa L. Gallant and published by DIANE Publishing. This book was released on 1998-05 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Produced as a framework for organizing and interpreting environmental data for inventory, monitoring, and research efforts. The descriptions of the 20 ecoregions of Alaska contained in this guide were derived by synthesizing information on the geographic distribution of environmental factors such as climate, terrain, soils, and vegetation. The specific procedures and materials used to delineate the ecoregion boundaries are documented, and the environmental characteristics in each ecoregion are described. Accompanied by a full-color oversize map of the ecoregions, their boundaries, and transitional areas. 42 full-color photos.

Download or read book Trace Fossils as Indicators of Sedimentary Environments written by Dirk Knaust and published by Newnes. This book was released on 2012-12-31 with total page 955 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integration of ichnological information into sedimentological models, and vice versa, is one of the main means by which we can improve our understanding of ancient depositional environments. Mainly intended for sedimentologists, this book aims to make ichnological methods as part of facies interpretation more popular, providing an analytical review of the ichnology of all major depositional environments and the use of ichnology in biostratigraphic and sequence stratigraphic analysis. It starts with an introduction to the historical aspect of ichnology, introducing common concepts and methods, and then continues with parts treating the main depositional systems from continental, shallow-marine and deep-marine siliciclastics, and marine carbonates. The last part is dedicated to the ichnology in hydrocarbon reservoir and aquifer characterization. - First overview in 25 years of the status of ichnological studies in facies reconstructions of all major depositional environments - Written by a selected, well-experienced and specialized international authorship - Provides easy access to the comprehensive and widespread literature

Download or read book Ichnoentomology written by Jorge Fernando Genise and published by Springer. This book was released on 2016-10-31 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.

Available in PDF, EPUB and Kindle. Book excerpt: This conference was prompted by the occurrence of 5 encounters between passenger jetliners with drifting clouds of volcanic ash from the 1989-90 eruptions of Redoubt Volcano in Alaska. Examines 5 principal areas, including: how volcanoes produce ash clouds, the damage and impacts resulting from ash-cloud encounters, communications procedures for mitigating the risks from volcanic ash, the meteorology and modeling of ash-cloud movement, and methods for detection and tracking of ash clouds. 60 technical presentations are included.

Download or read book Invasive Species in the Pacific Northwest written by P. Dee Boersma and published by Ewha Womans University Press. This book was released on 2006 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. government defines invasive species as "an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health." Invasive Species in the Pacific Northwest describes these species, how they got here, and the effects of their invasions on the region's environment. Each of 108 invasive species of fish, plants, invertebrates, mammals, and birds -- including earthworms, domestic cats and pigs, blackberries, European fruit flies, Japanese eelgrass, Mediterranean mussels, rats, and terrestrial mollusks -- is described in a 2-page spread that includes a full-color photograph of the species, a map showing the species' presence in the region, plus: -- Impact on communities and native species -- Control methods and management -- Life histories and species overview -- History of invasiveness Included are suggestions to help reduce the spread of invasive species; habitat preferences of Pacific Northwest invasive species; the World Conservation Union (ICUN) list of the world's 100 most invasive alien species; and a questionnaire designed to evaluate ecological impact and invasive potential. Invasive species have been recognized as an environmental issue since Charles Darwin's voyage on the H.M.S. Beagle. Editors P. D. Boersma, S. E. Reichard, and A. N. Van Buren explore the intentional and accidental introductions of invasive species. Whether these species were deliberately brought to the Northwest for agricultural, horticultural, aquacultural, or hunting and fishing purposes, or accidentally introduced as stowaways and contaminants, knowledge about them is integral to the protection of our environment.
