Seasonal variation in net ecosystem CO2 exchange of a Brazilian seasonally dry tropical forest

open access: yesScientific Reports, 2020
Forest ecosystems sequester large amounts of atmospheric CO2, and the contribution from seasonally dry tropical forests is not negligible. Thus, the objective of this study was to quantify and evaluate the seasonal and annual patterns of CO2 exchanges in

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.

Predicting the effects of climate change on water yield and forest production in the northeastern United States [PDF]

open access: yes, 1995
Rapid and simultaneous changes in temperature, precipitation and the atmospheric concentration of CO2 are predicted to occur over the next century. Simple, well-validated models of ecosystem function are required to predict the effects of these changes ...

Land-use change to bioenergy: grassland to short rotation coppice willow has an improved carbon balance [PDF]

open access: yes, 2017
The effect of a transition from grassland to second-generation (2G) bioenergy on soil carbon and greenhouse gas (GHG) balance is uncertain, with limited empirical data on which to validate landscape-scale models, sustainability criteria and energy ...

Seasonal patterns and controls on net ecosystem CO2 exchange in a boreal peatland complex [PDF]

open access: yes, 1998
We measured seasonal patterns of net ecosystem exchange (NEE) of CO2 in a diverse peatland complex underlain by discontinuous permafrost in northern Manitoba, Canada, as part of the Boreal Ecosystems Atmosphere Study (BOREAS).

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.

Complex responses of spring vegetation growth to climate in a moisture-limited alpine meadow. [PDF]

open access: yes, 2016
Since 2000, the phenology has advanced in some years and at some locations on the Qinghai-Tibetan Plateau, whereas it has been delayed in others. To understand the variations in spring vegetation growth in response to climate, we conducted both regional ...

Carbon uptake in Eurasian boreal forests dominates the high‐latitude net ecosystem carbon budget

open access: yesGlobal Change Biology, 2023
Arctic‐boreal landscapes are experiencing profound warming, along with changes in ecosystem moisture status and disturbance from fire. This region is of global importance in terms of carbon feedbacks to climate, yet the sign (sink or source) and ...

Net ecosystem CO2 exchange measurements by the closed chamber method and the eddy covariance technique and their dependence on atmospheric conditions – a case study [PDF]

open access: yes, 2013
. Carbon dioxide flux measurements in ecosystem sciences are mostly conducted by eddy covariance technique or the closed chamber method. Also some comparisons have been performed.

Net ecosystem productivity and its uncertainty in a diverse boreal peatland [PDF]

open access: yes, 1999
Net ecosystem exchange (NEE) of CO2 was measured in four peatlands along plant community, hydrologic, and water chemistry gradients from bog to rich fen in a diverse peatland complex near Thompson, Manitoba, as part of the Boreal Ecosystem-Atmosphere ...
