Sentences with phrase «photosynthetic activity in»

In a study of local ecosystem sustainability, Mohan Wali and his colleagues at Ohio State University noted that as temperature rises, photosynthetic activity in plants increases until the temperature reaches 20 degrees Celsius (68 degrees Fahrenheit).

To remedy that absence, Golden's lab, along with plant physiologist Takao Kondo and colleagues at Nagoya University in Japan, developed an easy - to - read gauge of changing photosynthetic activity in colonies of the cyanobacterium Synechococcus, a blue - green alga whose one - celled organisms divide as often as once every 5 to 6 hours.

Not exact matches

That data included dissolved oxygen in the water, pH, water temperature, salinity, photosynthetic activity and turbidity.

His research team envisions a series of interacting processes, or feedbacks, that maintained oxygen at very low levels principally by modulating the availability of life - sustaining nutrients in the ocean and thus oxygen - producing photosynthetic activity.

«If trends continue, we can expect probably a doubling of primary production,» in photosynthetic activity undertaken by millions of algae, he adds.

Scientists from the BOREA research unit first suspected the presence of microalgae in Paris streets after noting the characteristic green or brown color of gutter water and observing the presence of bubbles, which are the result of photosynthetic activity.

Hence, it could be suggested that the small differences in the calcification rates observed between 100 mg / L and 200 mg / L calcium additions during the day could be a result of relatively mediocre photosynthetic activities of the endo - symbionts, but this should be further studied.

The fluctuations in the CO2 curve (top) reflect seasonal changes in photosynthetic activity, which cause small differences between summer and winter concentrations of CO2.

Their photosynthetic activity is critically important to life in general.

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 methanogenesiIn 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 methanogenesiin 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.

(1) globally, photosynthetic activity (fixation of biomass) on both the land and oceans is demonstrably on the increase as a consequence of both the so - called CO2 fertilization effect AND the vastly increased anthropogenic N & P nutrient input to the continental shelves; and this in turn is

Human activity has also had a net negative effect on total global photosynthetic productivity since the most productive areas of land are directly in the path of urban sprawl [24].

Dr. Kiang also relates this work to research in astrobiology, particularly with regard to how photosynthetic activity produces signs of life at the global scale (e.g., biogenic gases like oxygen and photosynthetic pigments like chlorophyll) and how these may exhibit adaptations to alternative environments on extrasolar planets, resulting in other «biosignatures» that might be detected by space telescopes.

The scientists found the warm spring triggered leaf growth and photosynthetic activity earlier in the year than usual, which led to more carbon uptake than normal.
