However, "global photosynthesis" has the same features that characterize a normal photosynthesis. It consists of two reciprocal processes of CO2 assimilation and photorespiration. The strengthening of one of them is accompanied by the weakening of the other. The effect of each of the processes on the total biomass growth is opposite and depends on the concentration ratio of the CO2 and O2 in th...

[1] We analyzed measurements of net ecosystem exchange of CO2 (NEE) over 15 European forests (the EuroFlux data set) to investigate which climate and forest characteristics explain temporal and intersite variations in NEE and its components, gross primary production (GPP) and respiration (R). Informed stepwise regression was used to derive a parameter-efficient, empirical model that was consist...

Close coordination between leaf gas exchange and maximal hydraulic supply has been reported across diverse plant life forms. However, it has also been suggested that this relationship may become weak or break down completely within the angiosperms. We examined coordination between hydraulic, leaf vein, and gas-exchange traits across a diverse group of 35 evergreen Australian angiosperms, spanni...

Effects of vesicular-arbuscular mycorrhizal (VAM) infection and P on root respiration and dry matter allocation were studied in Plantago major L. ssp. pleiosperma (Pilger). By applying P, the relative growth rate of non-VAM controls and plants colonized by Glomus fasciculatum (Thaxt. sensu Gerdemann) Gerdemann and Trappe was increased to a similar extent (55-67%). However, leaf area ratio was i...

Carbon dioxide (CO2) efflux from the soil surface, which is a major source of CO2 from terrestrial ecosystems, represents the total CO2 production at all soil depths. Although many studies have estimated the vertical profile of the CO2 production rate, one of the difficulties in estimating the vertical profile is measuring diffusion coefficients of CO2 at all soil depths in a nondestructive man...

Six species of grass (four C3 and two C4) from southeastern Australian native pastures were grown in controlled environment cabinets at current (~370 !!mol CO2 mol-I) and twice current (~750 !!mol CO2 mol-I) cabinet [C02l. Photosynthetic gas exchange and aboveground biomass were estimated after seven weeks. Cabinet [C02l had a highly significant impact on above-ground biomass (P<0.0003) with pl...

Fast assimilation of monitoring data to update forecasts pressure buildup and carbon dioxide (CO2) plume migration under geologic uncertainties is a challenging problem in storage. The high computational cost with high-dimensional parameter space impedes fast decision-making for commercial-scale reservoir management. We propose leverage physical understandings porous medium flow behavior deep l...

The effect of individual nanometals (Co, Fe, Cu, Ge) carboxylates (NMC) as components the suspension for seeds inoculation with rhizobia on nitrogen fixation rate and parameters CO2 H2O gas exchange in soybean plants grown under different water conditions was investigated. scheme trials included following variants: 1 - + strain B1-20; 2 (strain B1-20 nano-cobalt carboxylate); 3 В1-20 nano-ferru...
