- Abstract:
- Over the past 400 Ma of the Phanerozoic global biodiversity, ecosystem function, biogeochemistry and climate have all varied considerably in response to a variety of internal and external forcing factors. These will have influenced atmospheric processes and led to major changes in the abundance of atmospheric O3, and therefore land surface fluxes of UV-B radiation, during the course of biotic evolution. Here we develop, for the first time, a terrestrial proxy for past UV climates based on geochemical analyses of plants grown experimentally under differing UV-B dosages, and extend these results back into the geological past through studies of fossil spores from key intervals of Earth history. The results will be underpinned by theoretical studies examining the influence of geological and biogeochemical processes on the chemistry of the ancient atmosphere.
