Researchers from three U.S. museums and two U.S. universities, plus a worldwide group of over 20 colleagues, will collaborate to conduct a global survey and inventory of the dwarf hunting spiders. These animals are very poorly known; preliminary data indicate that the 459 currently described species represent only about 20% of the actual diversity of the group. The team will assemble and sort the specimens available in collections and acquire new material through 12 expeditions that will concentrate on securing better samples of forest floor and canopy-dwelling species. Team members will build Internet-accessible databases of the species, all specimen locality data, and images; a new application will allow team members to enter descriptive data into a multi-user database, in a highly structured format that will allow direct use of that information in formal descriptions for publication, on species web pages, in phylogenetic analyses, and in interactive keys. Automated identification systems, using artificial neural networks, will be developed, and the accuracy of those systems will be compared with that achieved by workers, ranging from total beginners to knowledgeable specialists, using interactive keys to the same species.
Other impacts of the project include training several high school, undergraduate, graduate, and postdoctoral students (with emphasis on recruiting members of groups currently underrepresented in the science workforce). Project outreach plans include a major traveling museum exhibition designed to focus public attention on the importance and excitement of biodiversity discovery and preservation. Extensive public-aimed web materials will be developed that will be useful for pre-college level teaching.
