our planet's diversity remains unknown. Only a few years ago scientists shared the view that the diversity of life on Earth was so vast that it might be beyond cataloging, much less understanding. This is no longer the case. Advances in our capacity to collect, analyze, and integrate biological data have provided tools with which researchers can significantly expand our knowledge of Earth's biodiversity and revolutionize our understanding of the living world. Unfortunately, the pace of discovery is increasingly offset by rapid and permanent loss of biodiversity. Drivers of biodiversity loss include climate , over-exploitation of natural resources, planetary re-engineering (such as land use , water diversions, coastal development, fertilizer use), and the intentional or unintentional movement of species. With biodiversity loss, humanity is losing links in the web of life that provide ecosystem services, forfeiting opportunities to understand the history and future of the living world, and losing opportunities for future beneficial discoveries in the domains of food, fiber, fuel, pharmaceuticals, and bio-inspired innovation. This reality has stimulated a campaign of integrated study across the dimensions of Earth's biodiversity.

Biodiversity research has often ed on a single dimension. For example, investigators have concentrated on the taxonomic diversity or phylogenetic history of a clade, the genetic diversity of a population or a species, or the functional role of a taxon in an ecosystem. Although this research has yielded important advances, huge gaps persist in our understanding of biodiversity. We understand little about how these various dimensions, individually and in concert, contribute to environmental health, ecosystem stability, productivity, and resilience, or biological adaptation in response to rapid environmental .
