An ambitious project of The Council on Undergraduate Research, Research Link 2000 has harnessed the creative powers of college biology faculty "to select, develop and disseminate a group of field-tested, experimental systems and instructional materials that will support the introduction of research-based experiments in introductory biology courses." To that end, the Research Link 2000 homepage acts as a gateway for high-quality, online teaching resources, all of which target biology undergraduates. The heart of the site is the Research Systems section, where users may read about the various ecological systems/ organisms that are featured or follow links directly to the learning sites. Given the limited amount of high-quality, online information with direct utility to college laboratory instructors, this collection of resources promises to be a gold mine.
