Biological diversity is important for ecosystem function and services, which in turn is essential for human well-being. Under the Convention on Biological Diversity, international efforts have been made to achieve a significant reduction in the current rate of biodiversity loss. The loss continues, however. The Asia-Pacific region includes both developing countries with high biodiversity and developed countries with sophisticated data collection and analyses, but only limited information about the status quo of biodiversity in this region has been available. Many Asia-Pacific countries have rapidly grown their economies and social infrastructures, causing a loss of biodiversity and requiring an urgent mandate to achieve a balance between development and conservation in the region.  In December 2009, scientists successfully organized the Asia-Pacific Biodiversity Observation Network in the region, to establish a network for research and monitoring of ecosystems and biodiversity and to build a cooperative framework. The present volume is the first collection of information on biodiversity in the Asia-Pacific and represents a quantum step forward in science that optimizes the synergy between development and biodiversity conservation.

This volume focuses on new trends in monitoring biodiversity in the Asia-Pacific region, one of the most rapidly changing areas in the world. It provides reviews of the challenges in studying the spatial variability of biodiversity across various ecosystems. This book also describes newly developed concepts and methods for biodiversity observation including ubiquitous genotyping, systematic conservation, monitoring of the functions and services of ecosystems and biodiversity informatics. These contributions will lead to establishing integrative observations and assessments of biodiversity, essential for reporting the current status and for the effective conservation and sustainable use of biodiversity. This work will interest biodiversity researchers not only in the Asia-Pacific region but also across the entire globe.

This book focuses on the ecological impacts of the Great East Japan Earthquake and resulting tsunamis, a rare and extremely large disturbance event, on various coastal ecosystems in Japan’s Tohoku area, including sub-tidal and tidal animal communities, sand dune plant communities and coastal forests. The studies presented here describe not only how species and populations in these ecosystems were disturbed by the earthquake and tsunamis, but also how the communities have responded to the event and what types of anthropogenic activities will hamper their recovery processes.

In the ecological sciences, it is often argued that large disturbances are critical to shaping community structures and biodiversity in local and regional habitats. However, our understanding of these roles remains limited, simply because there have been few opportunities to examine and address the ecological impacts of large disturbance events.  The scale of the 2011 Great East Japan Earthquake makes it one of the largest hazards in the past 1000 years. Thus, this book provides a unique opportunity to advance our understanding of the ecological impacts of large and rare disturbances and the implications of these events in the conservation and management of coastal ecosystems. 

Following an outline of the Great East Japan Earthquake, the book’s content is divided into two major parts. Part I reports on studies examining the ecological impacts of the tsunamis on sub-tidal and tidal animal communities, while Part II focuses on terrestrial plant communities in Japan’s coastal Tohoku area.  

This book will benefit all scientists interested in the ecological impacts of large disturbances on aquatic and terrestrial ecosystems in general, and especially those who are interested in the ecological management of coastal ecosystems and Ecosystem based Disaster Risk Reduction (EcoDRR).

Biodiversity is decreasing at the fastest rate in the history of the earth, largely as a result of human activity. The sustainable use of ecosystems allowing maintenance of biological diversity is an urgent problem that must be solved. Among terrestrial ecosystems, forests support the richest biological diversity. The interaction of humans and forests has a long history, but recent changes have been the most drastic ever. The rapid decrease and deterioration of forest ecosystems has been caused by social, economic, and ecological factors, which may vary locally but are common globally. The mechanisms causing biodiversity loss through forest utilization and the results of that loss of biodiversity are still virtually unknown, although such knowledge is crucial to developing sustainable management strategies. The work featured in this book presents the results achieved by the RIHN project, together with reports on other international activities and related efforts, as ecologists, forestry scientists, environmental economists, and sociologists share in discussions of the issues.
