| highly diverse community structure in a remote central tibetan geothermal spring does not display monotonic variation to thermal stress. | we report an assessment of whole-community diversity for an extremely isolated geothermal location with considerable phylogenetic and phylogeographic novelty. we further demonstrate, using multiple statistical analyses of sequence data, that the response of community diversity is not monotonic to thermal stress along a gradient of 52-83 degrees c. a combination of domain- and division-specific pcr was used to obtain a broad spectrum of community phylotypes, which were resolved by denaturing grad ... | 2006 | 16819952 |
