New evidence for age-related decline in carbon sinks in intact boreal forests

Ecological Indicators
As climate change accelerates, understanding the carbon dynamics of intact forests is critical to climate forecasting, mitigation, and adaptation, but significant uncertainties persist regarding the long-term carbon balance of aging boreal forests. Here,

Controls on carbon and energy exchange by a black spruce - moss ecosystem: Testing the mathematical model Ecosys with data from the BOREAS experiment [PDF]

, 2001
Stomatal limitations to mass and energy exchange over boreal black spruce forests may be caused by low needle N concentrations that limit CO2 fixation rates.

Estimating daily forest carbon fluxes using a combination of ground and remotely sensed data [PDF]

, 2016
Several studies have demonstrated that Monteith’s approach can efficiently predict forest gross primary production (GPP), while the modeling of net ecosystem production (NEP) is more critical, requiring the additional simulation of forest respirations ...

Forest Net Primary Production Resistance Across a Gradient of Moderate Disturbance [PDF]

, 2014
The global carbon (C) balance is vulnerable to disturbances that alter terrestrial C uptake and loss. Moderate disturbances that kill or defoliate only a subset of canopy trees such as insect defoliation, drought, and age-related senescence are ...

Divergent responses of carbon fluxes to elevated temperature and precipitation: A meta-analysis in North Hemisphere grassland ecosystems

Global Ecology and Conservation
The manipulation experiments involving increased precipitation and elevated temperature have elucidated a series of responses to the carbon fluxes (gross ecosystem productivity (GEP), ecosystem respiration (ER), and net ecosystem productivity (NEP)) in ...
