Sentences with phrase «of microbial respiration»

OMZs are a consequence of microbial respiration and can be hostile environments for marine life.

Not exact matches

They write, «We show that anaerobic microsites are important regulators of soil carbon persistence, shifting microbial metabolism to less efficient anaerobic respiration and selectively protecting otherwise bioavailable, reduced organic compounds such as lipids and waxes from decomposition.

I also examine the partitioning of soil respiration into microbial and root respiration.

Estimates are that microbial respiration will speed up as the soil warms, resulting in a net flux of CO2 to the atmosphere.

One example is the global soil reservoir of organic carbon (which is not a single «pool», but which is made up of many components, some which are very labile (rapid turnover via microbial and root respiration) and some of which are very long - lived (humic material).

Estimates are that microbial respiration will speed up as the soil warms, resulting in a net flux of CO2 to the atmosphere.

Responses are expressed through gross and net primary production, microbial respiration, fire and insect disturbance, vegetation composition, species range expansion and contraction, surface energy balance and hydrology, active layer depth and permafrost thaw, and a range of other inter-related variables.

Other effects of SRM are expected to reduce soil microbial respiration, enhancing carbon storage in soils too.

Carbon fixed into plants is then cycled through plant tissues, litter and soil carbon and can be released back into the atmosphere by plant, microbial and animal respiration and other processes (e.g. forest fires) on a very wide range of time scales (seconds to millennia).

According to the paper, the results of the radiocarbon data confirm that microbial respiration of «old» carbon (carbon prior to nuclear tests in the 40s and 50s) has the potential to emit a significant amount of carbon into the atmosphere.

The present paper presents a mathematical analysis of a tipping point or runaway feedback that can arise when the heat from microbial respiration is generated more rapidly than it can escape from the soil to the atmosphere.

Some of this exchange is mediated by microbial marine organisms through photosynthesis, in which carbon dioxide is converted into organic matter, and respiration, in which the latter is metabolized.
