Sentences with phrase «affects photosynthesis»

OA affects photosynthesis and calcification of marine organisms such as coccolithophores [3 — 5], unicellular microalgae that surround themselves with scales of calcium carbonate (coccoliths).

The effect of solar dimming is a lower influx of sunlight that affects photosynthesis, among other things, and has profound consequences for the climate, the environment and the economy.

An intensification of oxygen depletion in the ocean therefore also has the potential to alter the global ocean inventory of nitrate, affecting photosynthesis in the ocean.

Prof Steve Wofsy of Harvard University says even a passing cloud can affect photosynthesis and growth.

What happens for example to the symbiotic algae that live within the coral's tissues if the turbidity caused by a reflective hydrosol should impede sufficient light reaching the algae and therefore affecting photosynthesis?

Taken together, the research data provides a picture, from the leaf scale to the global scale, suggesting that droughts in the Amazon basin are affecting levels of carbon dioxide in the atmosphere globally, both on a short - term basis though decreasing photosynthesis and on a longer term basis, by increasing tree mortality.

Researchers found that while the rate of photosynthesis was constant among trees on plots unaffected by drought, rates on the six drought - affected plots dropped significantly (as compared with before the 2010 drought).

The researchers also found that warming negatively affected tree photosynthesis and growth, regardless of whether pests were present.

«But, until our study, researchers have not been able to exactly quantify in observations how much photosynthesis, and the biosphere more generally, can affect weather and climate,» says Julia Green, Gentine's PhD student and the paper's lead author.

Seagrasses also undergo a high rate of photosynthesis that may serve to buffer changes in ocean chemistry that affect shell - building organisms.

Drought stress leads to water deficits in crops, which affects crop growth and development and a number of metabolic processes in the plants, such as photosynthesis and primary metabolism

«A lot of biologists are very interested in this machine because they want answers to the question of how plant photosynthesis is affected, because photosynthesis is the key to our life and health,» said Tanaka.

This includes cellular mechanisms such as photosynthesis and transpiration, and how plant processes are affected by environmental factors or natural variations.

Although intensely bright to the eye, the overall illumination would not significantly affect climate nor influence normal plant photosynthesis.

Production may be directly affected by changes in crop photosynthesis and water use due to rising CO2 and changes in regional temperature patterns.

However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant photosynthesis and water use efficiency, and ocean acidification).

I havent» found anything (in my copious five minutes of searching) about whether increased diffuse skylight affects plankton photosynthesis — or has effects on other biology that produces something paleo people look at for markers.

The quality and quantity of light has an impact on photosynthesis but at issue here is can the quality or quantity be so affected by an eruption to make such a remarkable response in tree growth?

This question arises when we see our world as a connected system and how the exercise of consumption or unfettered population growth affects other parts of the system (e.g. your mention of human confiscation of up to 40 % of solar input to photosynthesis must surely be putting extreme pressure on other species).

The terrestrial balance of respiration and photosynthesis is also affected — in soils and especially in regions of peat moss accumulation.

The ocean provide a vast area of sunlight, and anything which modestly increase the amount photosynthesis of ocean life, could have dramatic effects in terms affecting entire world.

As to your suggestion that my comments about photosynthesis contradict the possibility that CO2 affects radiation, the short answer is: You are wrong.

Is there any likelihood a bloom of plankton (from a freshwater pulse, or fallout of a dust cloud full of minerals, for example) would change the temperature of the surface water (change the reflectivity, I suppose, or change how much is absorbed by making more complicated molecules for photosynthesis)-- sufficient to make the water mass density change, affecting whether it sinks or not?

In turn, photosynthesis and calcification affect air — sea CO2 exchange and carbon export to the deep sea [6].
