Thermal optimality of net ecosystem exchange of carbon dioxide and underlying mechanisms [PDF]

open access: yesNew Phytologist, 2012
• It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales.

A Shift From Temperature to Water as the Primary Driver for Interannual Variability of the Tropical Carbon Cycle

open access: yesGeophysical Research Letters, 2023
The relative importance of temperature and water constraints on the tropical carbon cycle is an ongoing debate. Here we combine multiple independent tropical ecosystem carbon exchange simulations with satellite observations and show that the primary ...

Carbonyl sulfide (COS) as a tracer for canopy photosynthesis, transpiration and stomatal conductance : potential and limitations [PDF]

open access: yes, 2011
The theoretical basis for the link between the leaf exchange of carbonyl sulfide (COS), carbon dioxide (CO2) and water vapour (H2O) and the assumptions that need to be made in order to use COS as a tracer for canopy net photosynthesis, transpiration and ...

Seasonal and Inter-Annual Variations in Carbon Dioxide Exchange over an Alpine Grassland in the Eastern Qinghai-Tibetan Plateau.

open access: yesPLoS ONE, 2016
This work analyzed carbon dioxide exchange and its controlling factors over an alpine grassland on the eastern Qinghai-Tibetan Plateau. The main results show that air temperature and photosynthetically active radiation are two dominant factors ...

Global Assimilation of Remotely Sensed Leaf Area Index: The Impact of Updating More State Variables Within a Land Surface Model

open access: yesFrontiers in Water, 2022
As vegetation regulates water, carbon, and energy cycles from the local to the global scale, its accurate representation in land surface models is crucial.

A minimally managed switchgrass ecosystem in a humid subtropical climate is a source of carbon to the atmosphere

open access: yesGCB Bioenergy, 2022
Bioenergy has been identified as a key component of climate change mitigation. Therefore, quantifying the net carbon balance of bioenergy feedstocks is crucial for accurate projections of climate mitigation benefits.

Modeling of the net ecosystem exchange, gross primary production, and ecosystem respiration for peatland ecosystems of Western Siberia

open access: yesIOP Conference Series: Earth and Environmental Science, 2018
Observed and simulated carbon dioxide fluxes in oligotrophic peatlands of West Siberia are discussed. Net ecosystem exchange, gross primary production and ecosystem respiration were measured at ridge-hollow complex at South Taiga zone (Bakchar bog – field sataion “Vasjuganie”) and Middle Taiga zone (field station “Mukhrino”). The model of net ecosystem

Climate control of terrestrial carbon exchange across biomes and continents [PDF]

open access: yes, 2010
Understanding the relationships between climate and carbon exchange by terrestrial ecosystems is critical to predict future levels of atmospheric carbon dioxide because of the potential accelerating effects of positive climate–carbon cycle feedbacks ...
