Foliar morphology and canopy nitrogen as predictors of light-use efficiency in terrestrial vegetation
The net primary productivity (NPP) of a plant community is often positively and linearly related to the amount of photosynthetically active radiation absorbed by its canopy (APAR). The slope of this relationship is governed by the efficiency (ε) of APAR use in biomass production (NPP = APAR×ε). This intuitive model offers a promising means of generating large-scale NPP estimates, but its utilit...
متن کاملLegumes are different: Leaf nitrogen, photosynthesis, and water use efficiency.
Using robust, pairwise comparisons and a global dataset, we show that nitrogen concentration per unit leaf mass for nitrogen-fixing plants (N2FP; mainly legumes plus some actinorhizal species) in nonagricultural ecosystems is universally greater (43-100%) than that for other plants (OP). This difference is maintained across Koppen climate zones and growth forms and strongest in the wet tropics ...
متن کاملAcclimation of photosynthesis to light and canopy nitrogen distribution: an interpretation.
BACKGROUND AND AIMS Acclimation of photosynthesis to light and its connection with canopy nitrogen (N) distribution are considered. An interpretation of a proportionality between light-saturated photosynthesis and local averaged leaf irradiance is proposed by means of a simple model. MODEL The model assumes (a) local irradiance drives synthesis of photosynthetic protein from metabolic N; (b) ...
متن کاملThe Trade-off Between Fast Learning and Dynamic Efficiency
In both static and dynamic, independent private values setups, the efficient allocation is implementable if the distribution of agents’ values is known. Lack of knowledge about the distribution is inconsequential in the static case. But, if distribution of agents’ values is not known in a dynamic framework, and if the designer gradually learns about it by observing present values, endogenously ...
متن کاملNo Evidence of Trade-Off between Farm Efficiency and Resilience: Dependence of Resource-Use Efficiency on Land-Use Diversity
Efficiency in the use of resources stream-lined for expected conditions could lead to reduced system diversity and consequently endanger resilience. We tested the hypothesis of a trade-off between farm resource-use efficiency and land-use diversity. We applied stochastic frontier production models to assess the dependence of resource-use-efficiency on land-use diversity as illustrated by the Sh...
