Описание: Choice Outstanding Title! (January 2006)The image of Antarctica as a symbol of the last great wilderness and pristine environment has changed considerably in the last two decades. Environmental problems such as the ozone hole and the break-up of ice-shelves have shown that Antarctica is inextricably linked to global processes and exposed to the impact of human activities in the rest of the world. This volume provides an overview of climate change data, its effects on the structure and functioning of Antarctic ecosystems, and the occurrence and cycling of persistent contaminants. It discusses the unique physico-chemical characteristics of the Antarctic environment, ecophysiological adaptations of terrestrial and marine organisms, the transfer of contaminants in pelagic and neritic food chains and the possible consequences for animals at higher trophic levels. The text concludes with possible future scenarios of climate change and atmospheric contamination and the role of Antarctic organisms in the early detection of environmental perturbations.

Описание: Research in Antarctica in the past two decades has fundamentally changed our perceptions of the southern continent. This volume describes typical terrestrial environments of the maritime and continental Antarctic. Life and chemical processes are restricted to small ranges of ambient temperature, availability of water and nutrients. This is reflected not only in life processes, but also in those of weathering and pedogenesis. The volume focuses on interactions between plants, animals and soils. It includes aspects of climate change, soil development and biology, as well as above- and below-ground results of interdisciplinary research projects combining data from botany, zoology, microbiology, pedology, and soil ecology.

Описание: An up-to-the-minute overview of community studies in an area covering ten per cent of the Earth`s surface.
Описание: The Antarctic provides a suite of scenarios useful for investigating the range of climate change effects on terrestrial and limnetic biota. This book discusses the likely effects of climate change on Antarctic terrestrial and limnetic ecosystems.
Описание: The first book on the subject, this monograph examines the phenomenon of a huge sealed, freshwater lake, isolated from the rest of the world by kilometers' thick ice. The existence of melting ice at the bottom of the huge Vostok Lake has served as a model and inspired the team planning the Galileo space craft to gather data on the ice sheet of the Jupiterian moon Europa. The book provides interpretation of, and calculations for, stimulating factors for possible melting and a huge lake's existence at the bottom of the Martian ice sheets.

Описание: The fragile Antarctic environment consists of a closely linked system of the lithosphere, atmosphere, cryosphere, hydrosphere and biosphere. Changes in this system have influenced global climate, oceanography and sea level for most of Cenozoic time. The geological history of this region therefore provides a special record of important interactions between the various components of the Earth System. Antarctic Marine Geology is a comprehensive single-authored book to introduce students and researchers to the geological history of the region and the unique processes that occur there. Research literature on the region is widely disseminated. The book is intended as a reference for all scientists working in Antarctica, and will also serve as a textbook for graduate courses in Antarctic marine geology.

Описание: Examines the political and environmental questions raised by the potentially conflicting interests in the Antarctic.
Описание: It is generally understood that the Antarctic Ice Sheet plays a critical role in the changing global system. This atlas on the seventh continent contains 145 topographic and elevation maps derived from satellite data (GEOSAT and ERS-1 radar altimeter data). Each map is accompanied by a description of geographic and glaciological features.
Описание: The first evidence on the adverse effects of organic pollutants on Arctic ecosystems was provided by international research initiatives more than 30 years ago. Today, the indigenous people of the North are considered to be affected by exposure to persistent organic pollutants (POPs) and metals through their traditional marine food sources. The occurrence of pollutants of emerging concern in remote Polar environments is considered an essential criterion for prioritising this (largely neglected) type of contamination in national, international and global regulation schemes. Initiated during the first international Polar Years (IPY 2007-2009) and continued afterwards, 11 representative initiatives and projects are summarised as chapters in this book, which highlights today’s interdisciplinary research on POPs in the Polar environment. The individual chapters describe in detail the consequences, priorities and perspectives of international research on POPs (legacy and emerging xenobiotics), its implications for regulations and scientific priorities including societal and cultural developments in the Arctic, as well as conservation priorities in Antarctica. This book is intended for all readers interested in learning more about modern research on environmental pollutants in the Polar environments (with a strong focus on Arctic environments). The impacts of pollution and climate change on Polar regions and the world as a whole will continue to be felt for many years to come. Sound science is, thus, vital in order to underpin actions that need to be taken at the global, regional and local levels. This book contributes to this highly relevant, interdisciplinary environmental scientific endeavour.

Описание: This book provides a structured account of the full range of environments in Antarctica and of the microbial communities that live within them. Environments examined include: snow and ice; benthic marine; sea ice; lakes and streams; marginal ice; soil; the open ocean; rock. In the more extreme habitats of this region microscopic life forms constitute the entire biology of the habitat, but in all antarctic environments the microbial communities play a major and often dominant role in the transfer of carbon, nutrients and energy throughout the ecosystem. The book examines the major features of the chemical and physical environment in each habitat, and the influence of these features on the population structure and dynamics of their microbiota.
