SPRING SYMPOSIUM New Currents in Conserving Freshwater Systems American Museum of Natural History Center for Biodiversity and Conservation April 7 and 8, 2005 Freshwater New Currents in Conserving Freshwater Systems is sponsored by the American Museum of Natural History’s Center for Biodiversity and Conservation and the World Wildlife Fund, in collaboration with the National Oceanic and Atmospheric Administration, U.S. Fish and Wildlife Service, National Park Service, and U.S. Geological Survey. Support for New Currents in Conserving Freshwater Systems is provided by Daniel and Sheryl Tishman, and the Mack Lipkin Man and Nature Lecture Series. Additional support is provided by Symposium Content Coordinators: The Conservation Trust of the Robin Abell and Ian Harrison National Geographic Society, the Symposium Logistics Coordinator: American Society of Ichthyologists Fiona Brady and Herpetologists, The Nature Technology Coordinators: Tony Alexander Conservancy, and the American Ho-Ling Poon Fisheries Society. Program Editor: The Center for Biodiversity and Jennifer Stenzel Conservation was established with a leadership grant from The Starr Foundation Program Design: and the support of many other generous foundations, corporations, and individuals.

American Museum of Natural History NEW CURRENTS IN CONSERVING FRESHWATER SYSTEMS SPRING SYMPOSIUM Freshwater rivers, lakes, wetlands, springs, and groundwaters are home to an astounding wealth of life — tens of thousands of species of fish, invertebrates, reptiles, amphibians, birds, and mammals.These species are besieged by an array of threats ranging from the local to the global — dams, the invasion of exotic species, overfishing, pollution, stream channelization, water extraction and diversion, and the panoply of impacts linked to development of the terrestrial landscape.Across the world, freshwater habitats and species are among the most imperiled components of global biodiversity. Freshwater systems sustain all life, including human communities.While conserving the ecological integrity of these vital systems is a critical goal, it remains elusive. Dedicated scientists and managers have worked for decades to improve the health of freshwaters, yet in most places the outcome is far from certain.There is an urgent need to develop and apply innovative, science- based approaches to freshwater biodiversity conservation, and to share success stories. Because human activities are so closely tied to freshwater systems, conservation of the biodiversity within those systems faces a set of unique challenges.Working with users of water — local communities, industries, farmers, and others — to develop and implement sustainable solutions that meet the needs of both people and freshwater species is a basic foundation of many successes. Infusing these collaborations with the best science, even in the most data-poor situations, is integral to defining and achieving sustainability. Innovations in generating and applying that science represent an important conservation frontier. Just as freshwater biodiversity conservation must transcend “hard” science to include social, cultural, economic, and political considerations, so too does freshwater biodiversity science need to extend beyond biology.There is no doubt that strong biological information underpins effective conservation. But physical sciences like hydrology are equally important to the design and application of integrative conservation solutions. Bringing together scientists with shared interests and different disciplinary backgrounds to form working partnerships will be crucial to the next generation of freshwater conservation achievements. This symposium provides a forum for these interdisciplinary and international exchanges. Experts from around the world — researchers and practitioners with a range of experiences — will explore new collaborations and ideas for enhancing the effectiveness of their conserva- tion efforts.Whether innovations take the form of new scientific tools or improved methods for applying existing ones, the urgency of conserving freshwater biodiversity requires that we immediately embrace the best ideas and put them into action. 3 NEW CURRENTS IN CONSERVING FRESHWATER SYSTEMS A Biodiversity Science Symposium American Museum of Natural History Kaufmann and Linder Theaters DAY ONE Use of Genetic Tools to Examine Regional THURSDAY,APRIL 7, 2005 Patterns of Biodiversity 7:30 – 8:30 a.m. REGISTRATION DAVID J.
