*] in stems is high, i.e. 11.9 mmol l−1, and when transpiration rates are high, i.e. >3 mmol H2O m− 2 s−1, our estimates indicate the gross efflux of xylem-transported CO2* approaches half the rate of leaf ...
Darenova and Matjaž Čater Soil moisture, soil CO efflux (R ), and isotopic composition of R (δ ) were studied in three sessile oak forest stands with different management practice: a high forest (HF), a 2 S ...
, USA) at ~ 2 m height at each plot. Total larval abundance m- 2 for each plot was estimated by multiplying the number of collected larvae by four , since a plot covered an area of 0.25 m2. Gas production ...
was estimated from dpm for each time interval. By calculation of glucose-derived CO2, PE was then calculated as (equation (3)): $$\begin{eqnarray*}{\rm{PE}} = {{\rm{ CO }}_{{\rm{ 2 }}\;{\rm{Total}}}}\;{\rm ...
in Quebec, Canada was subjected to in situ soil warming and canopy nitrogen addition (CNA). The applied soil warming (+ 2 –4°C during the growing period) agrees with regional projections for 2050 [37]. Samples ...
-year-old Pinus sylvestris L. trees. A custom-built gas exchange system and an online isotopic analyser were used to sample the CO2 efflux and its isotopic composition continuously from four positions ...
into the atmosphere was registered by CRDS, and TCO2/EA could be estimated by an isotopic mass balance approach (Eq. (9)). Contrarily to our expectations, TCO2/EA averaged across the 2 -day labelling period did ...
. Positional cloning revealed that rte encodes a membrane-localized boron efflux transporter, co -orthologous to the Arabidopsis thaliana BOR1 protein. Depending on the availability of boron in the soil , rte ...
estimates from our study sites [see 14]: soil surface CO2 flux (Fs); C erosion, export, and CH4 efflux (FE); C inputs from aboveground leaf, fruit, and twig litter associated with above ground litterfall (FA ...
sylvestris L.) trees by utilizing month-long continuous measurements of stem CO2 efflux (Ec) made at four heights along the bole. Refixation rates were found to vary considerably along the bole, leading ...
