David Dudgeon is Chair Professor in Ecology & Biodiversity at the University of Hong Kong, where he has spent over 30 years researching the ecology, biodiversity and conservation of the animals that inhabit the streams and rivers monsoonal Asia. His recent work concerns food-web dynamics and energy flow in streams, the relationship between biodiversity and ecosystem functioning, and the broader issue of freshwater biodiversity conservation in a rapidly-changing, human-dominated world.
Dudgeon is the author of over 190 papers in international journals, as well as book chapters, books and other articles (see Publication List). He has supervised more than 30 research postgraduate students. In 2000, Dudgeon was awarded the 10th Biwako Prize in Ecology in recognition of his contributions to freshwater ecology and conservation in Asia. He is currently writing a book to entitled Freshwater Biodiversity Conservation for Cambridge University Press.
Dudgeon took on the role of Editor-in-Chief of Freshwater Biology between 2015 and 2017.
Dudgeon is a member of the editorial boards of Aquatic Conservation and Global Ecology and Conservation, and was formerly associated with the editorial boards of Hydrobiologia, Aquatic Sciences, Inland Waters and Biotropica. Dudgeon has served on the Freshwater Cross-cutting Network of DIVERSITAS, and sits on the Scientific Steering committee of the Global Water System Project (GWSP) and the Freshwater Working Group of GEO-BON, the Global Biodiversity Observation Network. These organizations were all members of the Earth Systems Science Partnership, which was recently incorporated into the Future Earth research platform.
Dudgeon is an Executive Councilor and Trustee of WWF-Hong Kong and a member of the Steering Committee developing the Hong Kong Biodiversity Strategy and Action Plan as part of the territory’s obligations under the international Convention on Biological Diversity. He served for six years on the Town Planning Board of Hong Kong SAR Government (until 2010), was Associate Dean (Research) of the HKU Science Faculty between 2010 and 2014, andwas University Mace Bearer until 2018.
Freshwater Biodiversity: Status, Threats and Conservation
Published in 2020.
From the dust-jacket: 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.
