| 英文简介 | A substantial fraction of the world's biodiversity is made up of species that are morphologically indistinguishable from other species (i.e. "cryptic species"). Efforts to preserve and protect global diversity rely on an understanding of how and why these cryptic species evolve and coexist. In this project, the moss genus Scleropodium will be used to examine how cryptic species coexist along a terrestrial/aquatic environmental gradient in California. Specimens will be collected and two of their genes will be sequenced to determine their identity. Ecological data collected for each specimen will be analyzed to determine how the species in question are distributed relative to each other and to the environment. Mosses perform important roles in carbon cycling in the northern latitudes, in water cycling in the tropics, and as constituents of biotic soil crusts in deserts. Despite their diversity and importance, mosses remain a poorly understood group of organisms. In California where this study will take place, new taxa continue to be discovered even as land development continues to reduce the amount of habitat necessary for current and future diversity. The fine scale ecological data captured in this study will prove useful in understanding the evolutionary processes and requirements necessary for maintenance of current and future species diversity. |
