The model involved takes into account the variation of the particle size distribution derived from the allocation of the scattered light energy using the Fraunhofer diffraction theory.
The decrease in the Jmax to Vcmax ratio observed in Q. spinosa is indicative of reduced allocation of nitrogen into light harvesting activities (Wullschleger 1993), possibly due to increased levels of radiation at the higher elevation.
(ii) The magnitude of trait variation in response to resource availability differs among traits and is greatest in traits related to allocation and the uptake of light and nutrients to maintain the 'functional equilibrium' at varying resource availability.
Some countries allow light work at ages below the minimum age of employment, and in one country (Trinidad and Tobago), we observe changes in time allocation that are consistent with changes in time allocation from light work regulation.
BALANCE reproduces growth and allocation patterns via the availability of light, nutrients and water (figure 9).
Plasticity was simulated for 3 intensively measured forest stands, to see to what extent and under what conditions the allocation of resources (e.g., light) to the individual trees depended on their ground coordinates.
The Commons authorities have announced they will tighten the rules for the allocation of Commons passes in the light of the recent lobbying scandal.
The greater root-to-leaf allocation of 2005 plants in high light conditions would maximize the supply of water and nutrients to photosynthetic tissues, allowing opportunistically high rates of carbon assimilation despite the transpirational demands of open habitats (Lechowicz and Blais 1988; Fitter and Hay 2002).
(Jankowski et al. [ 38] successfully manipulated infants' allocation of visual attention by shining lights at a display, although they did not assess transfer to other tasks; see also [ 39].) In this regard, it is striking that we found changes following briefer training periods than those used by other studies (77 min versus 375 min for 4- to 5-year-olds in Thorell et al. [ 4]).
Overheads included an allocation to cover light, heating and administration.
We tested for significant interactive effects of light and nutrient availabilities on foliage architecture, chemistry, biomass allocation and growth in shade intolerant temperate deciduous trees Betula pendula Roth.
