Its aims are the conservation of biological diversity, the sustainable use of biological resources, and the fair and equitable sharing of benefits arising from the use of genetic resources. One of the major challenges facing the Convention on Biological Diversity is the communication of research results in a way that provides the policy makers, their advisors, the scientific community and other stakeholders with helpful insights. STATUS AND TRENDS OF, AND THREATS TO, MOUNTAIN BIODIVERSITY, MARINE, COASTAL AND INLAND WATER Major factors leading to biodiversity loss are habitat loss and degradation, invasive alien ECOSYSTEMS: abstracts of poster presentations at species, overuse of resources and pollution. Due to the complexity of these factors, various the eighth meeting of the Subsidiary Body on Scientific, approaches and strategies are being used to reduce biodiversity loss. All, however, require the best available scientific information that allows the development and implementation of Technical and Technological Advice of the Convention sound management strategies. on Biological Diversity The goal of the CBD Technical Publications Series is to contribute to the dissemination of up-to-date and accurate information on selected topics that are important for the conserva- tion of biological diversity, the sustainable use of its components and the equitable sharing of its benefits. A large and growing body of evidence has clearly established the need to dissemi- nate synthesis publications relevant to CBD objectives and selected reports presented at CBD meetings. 8 The Technical Publications Series is intended to: • Foster scientific and technical cooperation; • Improve communication between the Convention and the scientific community; •Increase awareness of current biodiversity-related problems and concerns; and • Facilitate widespread and effective use of the growing body of scientific and techni- cal information on conserving and using biological diversity. The CBD Technical Publications Series comes at a time when the international community through the Conference of the Parties to the Convention has committed itself to achieving tan- ations at ity gible results in all aspects of the sustainable management of biological diversity for social and economic purposes. We therefore believe that this series will be useful to the broader scientif- ic community and those concerned with biodiversity management.

The Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) decided, at its seventh meeting held in November 2001, that mountain biological diversity would be the theme for in-depth discussion at its eighth meeting. It also decided that it would review the programme of work on biological diversity of inland water ecosystems and marine and coastal biological diversity. Mountain ecosystems are a new topic under this consultation process. They cover about 25 per cent of the Earth’s terrestrial surface. About 12 per cent of the world’s population lives in the mountains, but over 50 per cent are directly or indirectly dependent on mountain resources. Mountain biological diversity is of high importance for a number of ecological functions. The integrity of soils is the prime capital for ecosystem services and human needs. Soil retention and slope stability are closely connected with the extent of above- ground and below-ground vegetation, both essential to ecosystem resilience after disturbance (e.g., high rainfall, avalanches, trampling). The high plant functional diversity of mountain ecosystems may also add to their resiliency and, should extreme disturbances occur, often provides effective barriers to high-energy events such as rockfalls and avalanches. There is still no clear picture of the trends of mountain biological diversity. However, while several of the world’s mountain areas are in relatively good ecological shape, many face accelerating environmental and cultural decline. Although it is beyond doubt that human land use has greatly altered mountain ecosystems, the exact nature of some of the changes and future trends has yet to be established. I am very pleased to make available to the scientific community and those actively involved in biodiversity management the eighth publication in the CBD Technical Series. It contains an abstract of the keynote address delivered by Prof. Christian Köerner on “mountain biodiversity: global hot spots, regional insurance, local livelihood” and 27 abstracts on mountain biodiversity, 12 on marine and coastal biological diversity and 7 on inland water ecosystems presented at the eighth meeting of SBSTTA held in Montreal from 10 to 14 March 2003. It is my hope that this publication will broaden our understanding of the complexity of the issue of mountain biodiversity and at the same time facilitate the implementation of remedial measures to reduce or halt biodiversity loss attributed to many threats. I wish to express my sincere gratitude to all those who have contributed in one way or another to the preparation and production of this series.

Here, we focus on the exotic giant ragweed, which is a serious invasive weed in Japan. Recently, the exotic plant invaded and has dominated part of a semi-natural grassland in Sugadaira Montane Research Center (Nagano Prefecture, Japan). We attempted to evaluate the potential impact of the invasive plant on both plant and arthropod communities by comparing the com- munity composition, abundance, species richness and diversity indices of plants and arthropods between areas where the exotic giant ragweed had and had not invaded, referred to as the invaded and reference areas respectively. We found significant differences in plant and arthropod community compositions between the areas. Plant species richness was lower in the invaded area as predicted. However, the abundance of arthropods including herbivores was higher in the invaded area compared to the reference area in contrast to the expectation that plant invasions reduce arthropod abundance and diversity.

For me, this thrill is due to traversing different research terrains and gaining knowledge attributed mainly to having a supervisor like Professor T. Ramayah, with his vast expertise in research and analysis, and his generosity in imparting this knowledge to me. His guidance on materials for good methodology and his immediate feedback at any time of the day eased the process of completing this research tremendously. I am also grateful to Dr. Teh Sin Yin, for her thoroughness in examining my thesis during the proposal stage. I also truly appreciate my external examiner, Prof. Madya Dr. Rosmini Omar and my internal examiners Dr. Teh Sin Yin and Prof. Madya Dr. Shankar Chelliah for their thoroughness in reading my thesis and providing feedback to improve the quality of the thesis. This journey too would not have been possible if it was not for the blessings of my wonderful parents and brother, whose unconditional love and continuous emotional and financial support assisted me when facing challenges throughout this research process. The completion of this thesis would also not have been possible if not for the expertise of my friends, the computer whiz, Viswa, and the translation expert Jaja.

Part of the areas include the district of Ranau, Kota Marudu and Kota Belud. Some of the areas involved if not all are under a national park program prior to this. This gazettement undoubtedly has the potential to bring economic benefit to the state. It has the potential to increase land value, stimulating economic activities especially in the services sector via tourism activities, enhancing protection for environment and as a mean to control aggressive use of land for development. On the other hand, there are some concerns of stakeholders. Issues such as potential restriction for farmers to do agriculture related activities and relocation of village among others are potential concern among communities in Ranau, Kota Marudu and Kota Belud. In this regard, in order to examine the real concerns of various stakeholders, some series of roundtable discussions and interviews have been undertaken. Based on the preliminary assessment, very small number of individuals have worry about the geopark idea. Majority look at it positively.

We determined the species richness of Northeast Asia at various spatial scales, analyzed the floristic relationships among geographic regions within Northeast Asia, and compared the flora of Northeast Asia with surrounding floras. The flora of Northeast Asia consists of 971 genera and 4953 species of native vascular plants. Based on their worldwide distributions, the 971 gen- era were grouped into fourteen phytogeographic elements. Over 900 species of vascular plants are endemic to Northeast Asia. Northeast Asia shares 39% of its species with eastern Siberia-Mongolia, 24% with Europe, 16.2% with western North America, and 12.4% with eastern North America.
