Respiratory losses and carbon-use efficiency
How much of gross primary production is respired by leaves, wood and roots, which sets carbon-use efficiency (NPP divided by GPP) and the carbon left for growt…

Trophic transfer efficiency between levelsThe fraction of energy that passes from one trophic level to the next, which varies with ecosystem type, temperature, consumer physiology and trophic position.
6 steps inside · 👍1 👎0
Light-use efficiency control of gross primary productionHow much carbon a canopy fixes per unit of absorbed light, and how sky conditions (direct versus diffuse light) change that efficiency.
5 steps inside · 👍1 👎0
Nutrient limitation of net primary productionHow nitrogen and phosphorus supply caps plant growth, and how nitrogen fixation and nutrient losses shape which element limits production over time.

Belowground carbon allocation to roots and mycorrhizal fungiPart of net primary production goes to roots and arbuscular mycorrhizal fungi as a carbon payment for nutrient uptake, and this cost shrinks when nutrients are…
