Sentences with phrase «increase microbial activity»

Nutrient cycling may be affected by rising temperatures that, in turn, can increase microbial activity.

Lee tried tilling oil - soaked wetlands in Nova Scotia where there was limited oxygen to increase microbial activity.

The release of those gases from fertilized soils increases at high temperatures due to increased microbial activity, says Darrel Jenerette, an ecologist at the University of California, Riverside, who was not involved in the new study.

Not exact matches

[17] Whereas, when soil is tilled by machinery, the soil layers invert, air mixes in, and soil microbial activity dramatically increases over baseline levels.

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.

Viral infections simultaneously reduce the amount of nutrients and materials available to larger organisms by killing microbial cells, but also stimulate microbial activity through the release of organic matter and nutrients, which provides increased biomass available for larger organisms including fish.»

However, when intestinal microbial imbalances exist (e.g.: an overgrowth or infestation of harmful bacteria, viruses, protozoa, and / or fungus), an increase in the activity of the enzyme beta - glucuronidase can occur.

Increase in length of above - freezing air temperatures leads to boost in microbial activity and release of carbon.

As microbial activity is stimulated, there is a sharp reduction in dissolved oxygen levels and an increased risk of dead zones (high confidence).

Climate change can influence the distribution of dead zones by increasing water temperature and hence microbial activity, as well as reducing mixing of the ocean (i.e., increasing layering or stratification) of the Ocean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the Ocean.

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).
