This book offers a comprehensive account of the current state of inland waters in tropical and subtropical East Asia, exploring a series of case studies of freshwater fish, reptiles, amphibians, birds, mammals and water bodies at particular risk. The book highlights the rich freshwater biodiversity of tropical East Asia and draws attention to the various threats it faces due to human activities and rapid environmental change. It addresses the question of whether the contributions of these animals and habitats, or biodiversity in general, to ecosystem functioning and service provision provide sufficient basis for arguments supporting nature conservation. Drawing on instances from the rivers and lakes of tropical East Asia, the book also asks whether the benefits accruing from intact ecosystems are likely to be enough to ensure their preservation. If the answer to either or both these questions is ‘no’, then what are the prospects for freshwater biodiversity in rapidly changing tropical East Asia? This book will be of interest to students and scholars of biodiversity, conservation, freshwater ecology, ecosystem services and Asian Studies.

Freshwater Fishes of the Eastern Himalayas provides a guide to describe the internationally accepted methods used in the accurate identification of fishes, morphometry, i.e., body proportions, meristics, i.e., counts of countable characters, viz., scales, fin rays, pores, vertebrae etc., characters of bones wherever necessary, special characters, viz., serrations of fin spines, axillary lobes, lobes, color patterns, etc. All the available taxa of the region are covered, making this an essential reference that provides the original description of genera and species. Diagnostic characters in the book can be easily examined by an unaided eye or by a binocular dissecting microscope with transmitted light. Provides diagnostic characters which are unique for a species or a combination of characters to differentiate each species from its congeners Includes both verbal and technical aspects, along with color illustrations of the particular part of the fish showing the distinguishing character Presents diagnostic characters, illustrations or images of the fish and of its parts, showing the unique character and distribution to make it easy for species identification

The impact of invasive species is second only to that of human population growth and associated activities as a cause of the loss of biodiversity throughout the world. In the United States, invasions of nonnative plants, animals, or microbes cause major environmental damage. The second edition of Biological Invasions: Economic and Environmental Cos

Ichthyofauna of the freshwater system of South East Asia is extremely diverse. Recent estimate of about 1000 species is probably an under statement. More than 10 new species are being added to the list annually. The distribution pattern of the South-East Asian freshwater fishes can be divided into four zoogeographic regions. The first one is the Salween basin in Burma, with fishes mainly of the Indian subcontinent origin such as Amblypharyngodon atkinsoni, Bangana almorae and Brachydanio jayarami. The second zoogeographic area is the Mekong, Chao Phraya and Mae Khlong drainages which harbour fishes typical for the mainland of South East Asia such as Acanthorhodeus deignani, Barbichthys nitidus and Cirrhinus siamensis.
