Sentences with phrase «plant carbon uptake»

These parameters regulate processes such as plant carbon uptake by photosynthesis and how precipitation is separated into evapotranspiration to the atmosphere and river runoff.

The claim that CO2 immediately increases plant growth and acts as a fertilizer is a highly oversimplified argument, since plant carbon uptake is dependent on water, temperature, and nitrogen suppy.

Not exact matches

The researchers are particularly interested in the carbon cycle, the uptake of CO2 by plants as they grow and the recycling of some of this carbon back into the atmosphere via respiration.

And the satellite will also spy on plants» carbon uptake by measuring the weak fluorescence that is produced by chlorophyll during photosynthesis.

The researchers were surprised to learn that this speeding - up of carbon uptake during periods of slower warming was due mainly to less respiration from plants and not to greater photosynthesis.

Researchers at the U. of I. found that plants vary a lot in the efficiency with which they uptake carbon dioxide and conserve water.

«When you think from a climate point of view, you're not having carbon uptake across all this landscape for many decades when there's very little plant cover,» study co-author Steve Running, a University of Montana professor who models ecosystem functions, said.

The plants and their carbon uptake help the landscape provide certain «ecosystem services,» including food production, biodiversity and wildlife habitat, all of which are severely degraded when the landscape is denuded by oil and gas development.

«So mosses and other plants flourish in these lakes, leading to carbon uptake rates that are among the highest in the world, even compared to carbon - rich peatlands.»

The ground breaking research, conducted by scientists at the University of Sheffield, revealed why plants using C4 photosynthesis — a complex set of structural and chemical adaptations that have evolved more than 60 times to boost carbon uptake compared to the ancestral C3 plants — grow so rapidly.

When too many animals roam a field, they will trample plants and soil and impede carbon storage; when it's too wet, carbon uptake is impeded as well.

OCO - 2 will also closely monitor the carbon uptake of plants by measuring the weak fluorescence that is produced during photosynthesis as plants» chlorophyll pigments absorb light to capture energy and subsequently re-emit photons at longer wavelengths.

«When you think from a climate point of view, you're not having carbon uptake across all this landscape for many decades when there's very little plant cover,» study co-author

In the soil, researchers have found that microbes are essential for supporting plant life, mediating uptake and entry of nutrients into the food chain, cycling carbon and nitrogen, breaking down pollutants and much more.

For example, if it's a hot and dry afternoon, some plants may shut down their water use and carbon dioxide uptake in the afternoon.

The seasonal fluctuation is caused by variations in uptake of carbon dioxide by land plants.

Complete restoration of deforested areas is unrealistic, yet 100 GtC carbon drawdown is conceivable because: (1) the human - enhanced atmospheric CO2 level increases carbon uptake by some vegetation and soils, (2) improved agricultural practices can convert agriculture from a CO2 ource into a CO2 sink [174], (3) biomass - burning power plants with CO2 capture and storage can contribute to CO2 drawdown.

For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more heat 6) the warming slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.

Gu's research indicates that the maximum uptake of carbon dioxide by plant ecosystems occurs when cloud cover is about 50 percent.

When there's a transparent carbon sequestration market, (not the rigged stuff that passes for carbon trading now), then farmers will plant stuff, the plants will uptake carbon, and we'll leave some in the ground.

However, even today's most sophisticated Earth system models suffer from uncertainties that stem from the difficulty of simulating small - scale or complex processes, such as raindrop formation and carbon uptake by plants.

The reason for the accumulation is simple: Human activities are emitting more carbon dioxide than the planet's natural processes (uptake by plants and the ocean) can remove.

Climate science has been thrown into disarray by the hiatus, disagreement between climate model and instrumental estimates of climate sensitivity, uncertainties in carbon uptake by plants, and diverging interpretations of ocean heating (in the face of a dearth of observations).

Complete restoration of deforested areas is unrealistic, yet 100 GtC carbon drawdown is conceivable because: (1) the human - enhanced atmospheric CO2 level increases carbon uptake by some vegetation and soils, (2) improved agricultural practices can convert agriculture from a CO2 ource into a CO2 sink [174], (3) biomass - burning power plants with CO2 capture and storage can contribute to CO2 drawdown.

Carbon is a raw material for photosynthesis, and new carbon may accelerate plant growth, resulting in additional uptake.
