Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
Fresh waters are disproportionately rich in species, and represent global hotspots of biodiversity. However, they are also hotspots of endangerment.
About the Author
David Dudgeon is Chair Professor in Ecology and Biodiversity at the University of Hong Kong. He has spent almost forty years researching and writing about the streams and rivers of monsoonal East Asia, and the animals that live in and around them. He is well known and well respected internationally in the field of freshwater ecology, on which he has published extensively. He received the Biwako Prize in Ecology in 2000, and was Editor-in-Chief of Freshwater Biology between 2015 and 2017.
Reviews
'Dudgeon (Univ. of Hong Kong) draws on his 40 years of experience as a freshwater ecologist to provide a comprehensive overview of scientific research on these impacts. He adopts a global approach in every chapter, offering detailed examples from worldwide sites, such as the Mekong Basin, Lake Victoria, and the Great Lakes. After describing the biodiversity of freshwaters and their many uses by people, Dudgeon focuses on the three major causes of declining biodiversity: overexploitation (from fishing and hunting), introduced species, and modification of rivers and lakes (through dams and water removal). Many of the best-documented cases of biodiversity decline are found among fish, but other animals are not neglected. Climate change and its future effects are addressed as well. The book closes with a discussion of ways in which people may work to prevent and undo the harm to freshwater ecosystems and the many species that depend on them.' M. P. Gustafson, Choice
'In Freshwater Biodiversity, Dudgeon presents an impressive compilation of the status, threats, and prospects of the Earth's freshwater biodiversity that will be of great use for professionals or students interested in freshwater conservation ... readers interested in the freshwater conservation crisis will find this volume a valuable resource.' Windsor E. Aguirre, The Quarterly Review of Biology
