These 15th Proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar Arctic. Together with the previous 14 proceedings, they provide an historic record of the international effort in protecting, studying, and managing polar bears. The document addresses more recent concerns of threats arising as a consequence of increased human activities in both the Arctic and in regions far beyond the Arctic. Previous proceedings included a Status Report for each of the world's subpopulations, which focused largely on the known or unknown status as it related to harvest. In the Status Report of the 15th Proceedings, we provide a more comprehensive assessment of all threats to the status of each polar bear subpopulation.

This edited book covers major importance of tropical forest diversity and its values to vegetation, wildlife, and the local community. It addresses the current issues and opportunities in the Southeast Asia’s tropical forests. This book lays the groundwork for a better understanding of tropical forest ecosystem services. Ecosystem services has four concepts: provisioning, regulating, cultural and supporting services. In an era of rapid population growth and increasing pressure on tropical natural resources, ecosystem services have become central to the discussion of climate change mitigation. The values of tropical forest ecosystem services deserve to be the highlighted when it comes to shaping responsible behaviors towards sustainable development goals (SDGs). This book is of interest and useful to researchers and academics teaching in the field of tropical forest conservation, tropical ecosystems, tropical products technology, ecotourism, forest plantation management, bio industrial economy, agroforestry business and marketing. Professionals, foresters, industrial entrepreneurs, ecologists, and a valuable source of reference to the relevant researchers and students in the region.

This book brings together, for the first time, information on various wetland classification systems and wetland inventories from around the world, outlining regional, national and local wetland classifications developed in Africa, Australia, Canada, China, Europe, India, South America and the USA. Oriented towards the conservation and management of wetlands, these existing national and regional classification systems have been useful in providing an essential base for the development of an international system. The volume also reviews various attempts at drawing up an inventory of wetlands in different parts of the world, ranging from field and literature surveys to highly sophisticated efforts using aerial photography and satellite imaging. Audience: Workers in wetland ecology, especially those working on classification, inventory, conservation, or management of wetlands at the local, national, regional or international levels.
