Once thought of as a pristine environment, the Arctic is now known to be a sink for pollutants transported northwards over distances in the atmosphere and oceans, and is also likely to be subject to major climate change as a result of global warming. Many ecologists are currently seeking to further our understanding of how arctic ecosystems function, and to detect and predict anthropogenic changes which may occur within them.

Produktbeschreibung
Once thought of as a pristine environment, the Arctic is now known to be a sink for pollutants transported northwards over distances in the atmosphere and oceans, and is also likely to be subject to major climate change as a result of global warming. Many ecologists are currently seeking to further our understanding of how arctic ecosystems function, and to detect and predict anthropogenic changes which may occur within them. This book, resulting from a British Ecological Society Special Symposium, addresses these issues. Early chapters provide a background to the soils and periglacial processes of the Arctic, and the role of microbial and plant communities in ecosystem function. The following chapters consider the relationship between individual arctic species and their environment, particularly in the context of climate, whilst a further chapter draws together terrestrial and aquatic ecosystems. The book concludes with chapters concentrating on man's impacts on the arctic environment.

Table of contents:
1. Arctic soils and permafrost E. A. FitzPatrick; 2. Microbial ecology, decomposition and nutrient cycling C. H. Robinson and P. A. Wookey; 3. The role of bryophytes and lichens in polar ecosystems R. E. Longton; 4. The role of Arctic vegetation in ecosystem and global processes F. S. Chapin III, J. P. McFadden and S. E. Hobbie; 5. Habitat fragility as an aid to long-term survival in arctic vegetation R. M. M. Crawford; 6. Life strategies of arctic terrestrial arthropods J. S. Bale, I. D. Hodkinson, W. Block, N. R. Webb, S. C. Coulson and A. T. Strathdee; 7. Environmental fluctuations in arctic marine ecosystems as reflected by variability in reproduction of polar bears and ringed seals I. Stirling and N. J. Lunn; 8. Trophic interactions in arctic ecosystems and the occurrence of a terrestrial trophic cascade D. R. Bazely and R. L. Jefferies; 9. Pathways and effects of contaminants in the Arctic E. Steinnes; 10. Effects of acid deposition on arctic vegetation S. J. Woodin; 11. Effects of enhanced UV-B radiation on subarctic vegetation L. O. Björn, T. V. Callagham, C. Gehrke, D. Gwynn-Jones, B. Holmgren, U. Johanson and M. Sonesson; 12. The effects of CO2 and climate change on arctic ecosystems W. C. Oechel, A. C. Cook, S. J. Hastings and G. L. Vourltis.

Leading ecologists discuss the issues currently affecting the Arctic's environment in this important review. Coverage includes soils and periglacial processes, the role of microbial and plant communities in this ecosystem, the relationship between individual arctic species and their environment, and human impact.

The issues currently affecting the Arctic's environment are discussed by leading ecologists.
