Global simulations conducted by the team found that microbial responses to enhanced root activity under rising CO2, while depending on plant species, climate and soil mineralogy, led to a loss of global soil carbon stocks that counteracted the additional carbon storage resulting from increased plant growth in many regions of the world.
The authors argue that it comes from hydrothermal activity on the ocean floor, perhaps seafloor vents like those on Earth that spew H2 and support rich microbial life.

Reconstructing the evolution of early microbial life depends mainly on finding organic and mineral remnants of microbial activity preserved in the rock record.
They sent soil samples for DNA testing, looking for matches with particular genes known to be found in microbes and fungi; they tried to stimulate microbial growth on a wide variety of substances and then count the cells produced; and they used highly sensitive radiorespiration activity assays, which involve feeding the soil microorganisms a food source which has been labelled with radioactive carbon, which can then be used to detect if the microorganisms are active.
Lead author of the research Dr Kelly Redeker from the Department of Biology at the University of York said «As microbial activity and its influence on its local environment has never been taken into account when looking at ice - core gas samples it could provide a moderate source of error in climate history interpretations.

Current methane fluxes recorded in the water column from around these methane hotspots are > 1000x those expected from the observed atmospheric anomolies, so considerable methanotrophic activity could already be activated, making irregularities of microbial consumption potentially even capable of such a release on its own.
The reason was that wind and water erosion degraded the soil on the conventional farm while the soil on the organic farms steadily improved in organic matter, moisture, microbial activity and other soil quality indicators.
In the case of the cyanobacterial mat - covered polygonal ponds on Bylot Island, the negative CO2 flux most likely resulted from high photosynthetic rates in the mats, and the modern dates for CH4 suggest that abundant labile compounds coming from a modern autochthonous pool could be the main C supply for microbial activity, including methanogenesis.
Limited direct impacts of atmospheric CO2 on nitrogen - fixation have been found in soil biological crusts (Billings et al., 2003), but soil microbial activity beneath shrubs has been observed to increase, thus reducing plant - available nitrogen (Billings et al., 2002).
