May 2008. Over a decade of work and contributions by more than 200 leading conservation scientists, working for World Wildlife Fund and The Nature Conservancy, have produced an amazing first-ever comprehensive map and database of the diversity of life in the world’s freshwater ecosystems. The map and associated data are featured in the May issue of the journal BioScience.
