Download or read book Mountain Landscapes in Transition written by Udo Schickhoff and published by Springer Nature. This book was released on 2021-11-02 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book compiles available knowledge of the response of mountain ecosystems to recent climate and land use change and intends to bridge the gap between science, policy and the community concerned. The chapters present key concepts, major drivers and key processes of mountain response, providing transdisciplinary orientation to mountain studies incorporating experiences of academics, community leaders and policy-makers from developed and less developed countries. The book chapters are arranged in two sections. The first section concerns the response processes of mountain environments to climate change. This section addresses climate change itself (past, current and future changes of temperature and precipitation) and its impacts on the cryosphere, hydrosphere, biosphere, and human-environment systems. The second section focuses on the response processes of mountain environments to land use/land cover change. The case studies address effects of changing agriculture and pastoralism, forest/water resources management and urbanization processes, landscape management, and biodiversity conservation. The book is designed as an interdisciplinary publication which critically evaluates developments in mountains of the world with contributions from both social and natural sciences.
Download or read book Life at Rock Surfaces written by Burkhard Büdel and published by Walter de Gruyter GmbH & Co KG. This book was released on 2021-06-08 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rock surfaces provide a challenging habitat for a broad diversity of micro- or small-sized organisms. They interact with each other forming complex communities as well with their substrate causing biodeterioration of rock. Extreme fluctuation in light, temperature and hydration are the main factors that determine the rock surface habitats. The habitat includes epilithic organisms which thrive on the surface without penetrating the rock, endolithic organisms which live just beneath the surface using a thin layer of the rock surface for protection against adverse conditions of the environment (e.g. light protection, storage of water) and chasmo-endolithic organisms which use fractures of the rock surface for a more habitable environment. The book will provide an overview of the various organismal groups, from prokaryotes to vascular plants and arthropods, as well as survey organism-mediated interactions with the rock surface. The latter include biogenic weathering (biogeochemistry, state-of-the art imaging methods), photosynthesis and nitrogen fixation at and inside the rock surface.
Download or read book Flora of Alaska and Neighboring Territories written by Eric Hultén and published by Stanford University Press. This book was released on 1968 with total page 1050 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monumental work by the world's preeminent authority on Arctic floras--the first comprehensive, up-to-date botanic manual for this region--is the product of the author's more than forty years of study of circumpolar floras. The book describes and illustrates all flowering plants and vascular cryptograms known to occur in Alaska, the Yukon, the Mackenzie District, and the eastern extremity of Siberia. Some 1,974 taxa, belonging to 1,559 species, occur in this region; all are described. For 1,735 of these, the book provides detailed description, nomenclature, plant drawing, and range maps. In each case, one map gives distribution in the Alaskan region; a second, on circumpolar projection, gives worldwide range. This volume is the first major flora to assemble such comprehensive range data and to provide such maps. An analytic key to all species described is provided for each genus, and there is an artificial key to families. An Introduction describes the past and present climatic, geologic, and ecologic character of the regions covered, the history of botanical collection in these regions, and the book's treatment of botanical and taxonomic details; and lists the plants of neighboring regions likely to occur. Glossary, plant authors' list, bibliography, and indexes are provided. The superb drawings were prepared by Dagny Tande-Lid, and eight pages of illustration in color are included.
Download or read book Arctic and Alpine Biodiversity Patterns Causes and Ecosystem Consequences written by F.Stuart III Chapin and published by Springer. This book was released on 2012-02-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.
Download or read book Paleoecology of Beringia written by David M. Hopkins and published by Elsevier. This book was released on 2013-09-17 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleoecology of Beringia is the product of a symposium organized by its editors, sponsored by the Wenner-Gren Foundation for Anthropological Research, and held at the foundation's conference center in Burg Wartenstein, Austria, 8-17 June 1979. The focus of this volume is on the paradox central to all studies of the unglaciated Arctic during the last Ice Age: that vertebrate fossils indicate that from 45,000 to 11,000 years BP an environment considerably more diverse and productive than the present one existed, whereas the botanical record, where it is not silent, supports a far more conservative appraisal of the region's ability to sustain any but the sparsest forms of plant and animal life. The volume is organized into seven parts. Part 1 focuses on the paleogeography of the Beringia. The studies in Part 2 explore the ancient vegatation. Part 3 deals with the steppe-tundra concept and its application in Beringia. Part 4 examines the paleoclimate while Part 5 is devoted to the biology of surviving relatives of the Pleistocene ungulates. Part 6 takes up the presence of man in ancient Beringia. Part 7 assesses the paleoecology of Beringia during the last 40,000 years

This book was released on 1998-07-31 with total page 793 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fresh water supplies of the Earth are finite and as the world's population continues to grow humanity's thirst for this water seems unquenchable. Intense pressure is being exerted upon freshwater resources and a lack of adequate clean water is seen as one of the most serious global problems for the 21st century. Indeed it has been said that the next war will be fought over water, not oil. Human health and the health of supporting ecosystems increasingly depends upon our ability to find, control, manage and understand water. In a single volume, The Encyclopedia of Hydrology and Water Resources provides the reader with a comprehensive overview and understanding of the diverse field of hydrology. The intimate inclusion of material on water resources emphasizes the practical applications of this field, applications which are indispensable in any modern approach to the subject. This volume is a vital reference for all hydrologists, hydrogeologists and water engineers worldwide, whether they are concerned with the exploitation of new sources of water, the protection and management of existing reserves, or the science of surface water and groundwater flow. 114 eminent scientists from 17 countries worldwide have contributed to this authoritative volume. Superbly illustrated throughout, it includes almost 300 entries on a range of key topics, including arid and semi-arid zones, climates and climate change, floods and droughts, desertification, entropy, flow measurement, groundwater, hydrological cycle, hydrological models, infiltration, karst hydrology, paleohydrology, precipitation, remote sensing, river pollution prevention, rivers, lakes and seas, satellite hydrology, soil erosion, water treatment, water use, weather radar, and world water balance.

Download or read book Ecological responses to environment stresses written by Jelte Rozema and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: September 1987, the Faculty Biology of the Vrije Universiteit, Amsterdam commemorated the fact that Prof. Dr. Wilfried Hans Otto Ernst had been active as a scientist for 25 years. This period of 25 years of scientific research started at the Institut flir Angewandte Botanik (Institute of Applied Botany) of the University of Munster, FRG. In 1965 he completed his Ph. D. thesis, entitled "Untersuchungen der Schwermetallpflanzengesellschaften Mitteleuropas unter Einschluss der Alpen. " He was appointed full Professor at the Department of Ecology of the Vrije Universiteit, Amsterdam in 1973. On the occasion of his 25th anniversary as a scientist, a promise was made, though in covert terms, which we could not redeem at that time. The promise held to offer Prof. Ernst a book, in which his former and present staffmembers, Ph. D. students and colle ages should write a review about their specialism concerning a central theme. Now, at the beginning of 1990 we consider the chapters of "Ecological Responses to Environmental Stresses" to be completed. The book reflects the wide range of research approaches that has been initiated and organized by Wilfried Ernst. The editors hope to have attained the primary aim of the production of the book of friends, that is to gather relevant papers of staff-members and colleagues of Wilfried Ernst. The title of the book "Ecological Responses to Environmental Stresses" covers the majority of the chapters included.
