| This dissertation examines biodiversity at multiple temporal and spatial scales and integrates theory and methods from multiple disciplines to generate a synthetic view of biodiversity patterns. At the core of this integration is the information contained in a species identity. I have demonstrated the importance of species identity in not only description of pattern, but also understanding the underlying processes. Additionally, I have characterized the uniqueness of Yellowstone mammal composition within western North America and its importance to regional diversity. My analysis of the contribution of different biomes to continental diversity shows how unique histories of species and biomes lead to modern patterns of diversity. Finally, my analysis of turnover in vertebrate assemblages presents a new direction for applying our understanding of biodiversity patterns to conservation, with specific recommendations. These analyses refine our understanding of how biodiversity is arranged around the globe and chart a path forward that integrates disciplines and incorporates lessons from basic science into application. |
