Sentences with phrase «high photosynthetic»

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 methanogenesis.

A team of researchers led by Carnegie's Ute Armbruster and Martin Jonikas revealed a mechanism by which plants maintain high photosynthetic efficiency in fluctuating light.

Fast - growing plants have higher photosynthetic rates, which are also influenced by light, temperature, vapor pressure deficit, and carbon dioxide.

A novel nanobionic approach has been developed that imparts higher photosynthetic activity to plant leaves and extracted plant chloroplasts, the biological organelles that convert captured carbon dioxide into solar energy.

Using high - performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion people on it by 2050, researchers report in the journal Cell.

In the open seas, heavy winds and deep waters lead to a high turnover in the water column, which prevents photosynthetic microorganisms like algae from converting sunlight into energy.

Exploiting habitats that are often or mostly out of water required new symbiotic relationships to contain and move water, including the fusion of some fungi and algae to create lichen in communities with bacteria that survive extreme desiccation on land while breaking down rock into soil, and the association of mycorrhizae fungi and the root tissue of new vascular plants — culminating in trees that pump water high into the air — to exchange mineral nutrients (e.g., phosphorus) and usable «fixed» nitrogen from the atmosphere for photosynthetic products.

«Coral breaching, in which symbiotic photosynthetic algae of corals are killed by high temperatures and coral reefs are severely damaged, is regarded as a serious environmental issue, but plausibly, similar phenomena may be ubiquitously found in the ecosystem,» said Dr. Fukatsu.

Re posts 8 & 3: I think only photosynthetic organisms gain a direct benefit from higher CO2, and fishes are certain not to benefit (although some fish species may be less sensitive to HCO3 than others and receive an indirect benefit via ecological interactions).

Largely because of these mechanisms, most marine phytoplankton tested in single - species laboratory studies and field population experiments show little or no change in photosynthetic rates when grown under high pCO2 conditions equivalent to ∼ 760 μatm (Tortell et al. 1997, Hein & Sand - Jensen 1997, Burkhardt et al. 2001, Tortell & Morell 2002, Rost et al. 2003, Beardall & Raven 2004, Giordano et al. 2005, Martin & Tortell 2006).

Our model suggests that although reductions in photosynthetic rate at leaf temperatures (TL) above 30 oC may occur, these are almost entirely accountable for in terms of reductions in stomatal conductance in response to higher leaf - to - air vapour pressure deficits D.

Furthermore, higher CO2 will likely increase the competitive ability of plants that use the C3 photosynthetic pathway relative to C4 plants.

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increased.72

The result of putting more carbon into the atmosphere than can be taken out of it is a warmer climate, a melting Arctic, higher sea levels, improvements in the photosynthetic efficiency of many plants, an intensification of the hydrologic cycle of evaporation and precipitation, and new ocean chemistry.

According to NOAA, photosynthetic algae and seagrasses may benefit from higher CO2 levels.
