Figure 1. Fraction of above-canopy PPFD reaching the fixed sensors during clear (diffuse PPFD < 30% of total) and overcast (diffuse PPFD > 70% of total) conditions
Figure 5. Nothofagus leaf assimilation as a function of temperature (leaf--air vapor pressure difference < 1 kPa)
Figure 8. Relationship between microsite fraction of above-canopy PPFD and N allocation for the observed canopy (circles), for an optimal distribution of N when leaf N is constrained to the range of values observed in the field (triangles and dotted line),

The model was used to estimate light use efficiency at a range of leaf N contents, and two atmos- pheric CO2 concentrations (350 and 700 ppmv), for the follow- ing assumptions: (1)

To obtain a more detailed understanding of how environmental variables limit primary production at the single leaf level, we examined diurnal changes in microclimate and leaf

More importantly, the fraction of total biomass allocated to fine roots (fine root ratio) increased significantly in response to a doubling of the ambient CO2, i.e., elevated CO2 led

Primary leaf formation could also be induced in etiolated seedlings when the roots were exposed to a 5 min pulse of white light or red light, and the kinetics of leaf formation

Sobrado, Effect of high external N aCl concentra- tion on the osmolality of xylem sap, leaf tissue and leaf glands secretion of the mangrove A 6 icennia germinans. (L.), F lora

For xed total sample size N , the best allocation for the ratio approach dominates that of the best allocation for the dierence approach in terms of the correct identication of

I n this paper I present some ideas related to teaching cardiac pump dynamics and regulation to first-year medical students. I emphasize explicit presentation of the relation

• For the teacher: The book ap- proaches physiological questions in a very direct manner, showing how KS-N went about uncovering precise mechanisms of the organism in its
