Anthropogenic transformation of the terrestrial biosphere.
Human populations and their use of land have transformed most of the terrestrial biosphere into anthropogenic biomes (anthromes), causing a variety of novel ecological patterns and processes to emerge. To assess whether human populations and their use of land have directly altered the terrestrial biosphere sufficiently to indicate that the Earth system has entered a new geological epoch, spatia...
متن کاملReconnecting to the biosphere.
Humanity has emerged as a major force in the operation of the biosphere, with a significant imprint on the Earth System, challenging social-ecological resilience. This new situation calls for a fundamental shift in perspectives, world views, and institutions. Human development and progress must be reconnected to the capacity of the biosphere and essential ecosystem services to be sustained. Gov...
متن کاملBioengineering the biosphere?
SFI Working Papers contain accounts of scienti5ic work of the author(s) and do not necessarily represent the views of the Santa Fe Institute. We accept papers intended for publication in peer-‐reviewed journals or proceedings volumes, but not papers that have already appeared in print. Except for papers by our external faculty, papers must be based on work done at SFI, inspired by an invited v...
متن کاملWeighing the deep continental biosphere.
There is abundant evidence for widespread microbial activity in deep continental fractures and aquifers, with important implications for biogeochemical cycling on Earth and the habitability of other planetary bodies. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) estimated a continental subsurface biomass on the order of 10(16) -10(17) g C. We reassess this value in the light of more rece...
متن کاملMapping the protistan 'rare biosphere'
The use of cultivation-independent approaches to map microbial diversity, including recent work published in BMC Biology, has now shown that protists, like bacteria/archaea, are much more diverse than had been realized. Uncovering eukaryotic diversity may now be limited not by access to samples or cost but rather by the availability of full-length reference sequence data.
