7 PREFACE The 8th International Congress of Ecology was held in Seoul, South Korea in August 2002, and was hosted by the Ecological Society of Korea. The Congress theme was 'Ecological Issues in a Changing World', and this volume includes selected contributions to illustrate some of the important topics which were discussed during the Congress. Problems of scale have exercised the minds of ecologists for many years, and will continue to do so into the future. This volume deals with this subject and with mathematical approaches to improve our understanding of complex ecological systems. The book also concentrates on monitoring the responses of ecosystems particularly to human impacts upon them. The importance of spatial separation of function at both the landscape and ecosystem level forms an important theme. Finally, this special book focuses on large-scale issues, discussing in particular important applied ecological problems and how these can be managed through a variety of planning processes. Many examples of major ecological problems in the mainstream ecological literature are drawn from Europe and North America. In contrast, many of the most pressing ecological problems are to be found elsewhere in the World. The 8th INTECOL International Congress of Ecology set out in part to help to redress this situation. Many of the sessions discussed major problems of the Asian region with a view to their wider appreciation in the ecological community at large. This volume continues this process drawing many examples from China, Japan and importantly South Korea. The expertise of ecologists from these countries, the range of the ecological problems which they face, and their solutions to them provide the major substance of this book. Those of us from other parts of the World who attended the Congress were fascinated by the range of major ecological questions being addressed by our Asian colleagues. This deserves to be more widely appreciated in the ecological community. This volume is an important step in this process. This volume is composed of four parts according to scale, objectives and application of modern ecological research. Part I covers emerging concepts and models in the ecosystem complex and in the landscape. Part II. Biological responses to environmental changes: pattern and process, Part III. Ecological networking and restoration technology: theory and practice, and finally a summary of 8 th INTECOL Congress and possible future directions are covered in Part IV. In Part I. Concepts and models in the ecosystem complex each chapter discusses several emerging theories and their ecological methodologies. At this point in time our understanding of ecosystem configuration, ecological function and dynamics is advanced by spatial analyses and models, and by interdisciplinary theories and concepts (esp. ecosystem complexity, landscape ecology and spatial ix

8 models). The advancement of new concepts and the development of spatial analysis technology help us to understand ecosystem complexity and major global environmental problems. This section covers concepts and theoretical model in the spatio-temporally-different ecosystems and their importance for scaling up from ecosystems through the human-landscape system scale to the global scale. Part II. Ecological responses in global environmental change: pattern and process focuses on ecological responses to major environmental change factors. Ecological responses to these factors are potentially very important indicators of ecosystem health and environmental conditions. These 8 chapters discuss the cause and consequence of ecosystem stability and health in the light of the ecological responses of organisms. They also deal with scaling from ecosystems to the global level in considering the impacts of climate change and pollutants. Practical models and solutions to ecosystem stability are also discussed by world. Part II also contains several papers discussing biological conservation and biodiversity monitoring techniques. Conservation of biodiversity is major current issue. Although the threat to biodiversity is well recognized, the crisis still continues in many of the World s biomes. This section covers several ecosystems which are highly threatened by recent land developments. The strategy of maximizing the conservation of biodiversity is often very concerned with habitat or landscape conservation surrounding target organisms. Therefore, biodiversity conservation practioners are trying to understand habitat structure and related ecological functions. Issues of biodoversity and habitat conservation are strongly correlated to each other and are also important for human health and the environmental beauty of the earth. This section also discusses the interface between ecological and human sociological issues. Part III. Ecological networking and restoration technology: theory and practice, considers habitat networking problems associated with expanding human settlements and the exploitation of natural resources. Urgent issues are concerned with ecological restoration perspectives at both the ecosystem and landscape scale. The need for new environmental impact assessments of human-dominated ecosystems is explored. The need to balance ecosystem conservation and human development in several landscape types (urban-suburban, agricultural, watersheds and rivers) is explored. In this part, new theories of landscape planning, the restoration technology of land management and ecological engineering are suggested as new methodologies of environmental impact assessment and ecosystem information. The papers show new paradigms of sustainable land use and society and the vital importance of global ecology and networking in a changing world. Part IV. The Epilogue deals with the necessity of international networking by active co-operation in order to solve the environmental problems. The International Congress of Ecology in Seoul involved the participation of many international and domestic academic associations. Their roles and strong support were major factors leading to the success of the Congress. Notable examples include the International Association for Landscape Ecology (IALE) which was an important supporter. During the Congress, this group showed new solutions of environmental problems at x

9 both the local and the global scale. The Long-term ecological research network (LTER) is another international organization working at both the local and global scale. The new methodologies in several fields of ecology were discussed, especially in consideration of USA and Chinese LTER sites. One of the most valuable outcomes from the 8 th International Congress of Ecology was the establishment of the East Asian Federation of Ecological Societies (EAFES). This is a most important development for ecologists in the region, leading to much greater co-operation and interchange of ideas. The mutually beneficial activities of EAFES and INTECOL will help such co-operation between ecologists world wide, and will be important in addressing the major ecological problems which will confront us in the 21 st Century.

14 Acknowledgements Above all, we would like to express our deepest appreciation to those ecologists from 55 countries who presented some 1267 papers during the 50 symposia held as part of the 8 th INTECOL Congress in Seoul in This book consists of major 23 papers that were organized during the Congress, and includes the valuable works of 59 contributors. It was the presentations made during the various symposia that gave us the courage to publish this book. In addition to the seven editors of the book, the following authors were generous enough to agree to have their papers published in this book: Jan Bogaert, Young Son Cho, Jinhee Choi, Sei-woong Choi, Yeoung-Kook Choi, Tae-Soo Chon, Yeong-Jin Chung, Chris Freeman, Robert H.
