Carbon budget of the vineyard \u2013 A new feature of sustainability [PDF]

open access: yes, 2015
Vineyards received scarce attention in relation to the continuous monitoring of carbon fluxes and the assessment of their overall budget, as a common believe is that agricultural crops cannot be net carbon sinks.

NEP of a Swiss subalpine forest is significantly driven not only by current but also by previous year's weather [PDF]

open access: yesBiogeosciences, 2014
Understanding the response of forest net ecosystem productivity (NEP) to environmental drivers under climate change is highly relevant for predictions of annual forest carbon (C) flux budgets.

Interannual Carbon Exchange Variability of Rain-fed Maize Fields in Northeast China and Its Influencing Factors

open access: yes应用气象学报, 2023
Interannual variation in net ecosystem carbon production (NEP) plays an important role in the carbon cycle processes. An agricultural ecosystem may fluctuate between carbon net source and carbon sink, or it may remain neutral.

Climate Change Decreased Net Ecosystem Productivity in the Arid Region of Central Asia

open access: yesRemote Sensing, 2021
Numerous studies have confirmed that climate change leads to a decrease in the net ecosystem productivity (NEP) of terrestrial ecosystems and alters regional carbon source/sink patterns.

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 ...

Characteristics of carbon sources and sinks and their relationships with climate factors during the desertification reversal process in Yulin, China

open access: yesFrontiers in Forests and Global Change, 2023
Research on carbon sources/sinks in desert ecosystems is of great importance to understand the carbon cycle and its response to climate change. Net primary productivity (NPP) and net ecosystem productivity (NEP) are the two most important indictors for ...

Generalization and evaluation of the process-based forest ecosystem model PnET-CN for other biomes [PDF]

open access: yes, 2015
Terrestrial ecosystems play an important role in carbon, water, and nitrogen cycling. Process-based ecosystem models, including PnET-CN, have been widely used to simulate ecosystem processes during the last two decades.

Modelling effects of seasonal variation in water table depth on net ecosystem CO2 exchange of a tropical peatland [PDF]

open access: yesBiogeosciences, 2014
Seasonal variation in water table depth (WTD) determines the balance between aggradation and degradation of tropical peatlands. Longer dry seasons together with human interventions (e.g.

Water use efficiency of China\u27s terrestrial ecosystems and responses to drought [PDF]

open access: yes, 2015
Water use efficiency (WUE) measures the trade-off between carbon gain and water loss of terrestrial ecosystems, and better understanding its dynamics and controlling factors is essential for predicting ecosystem responses to climate change.

Strong radiative effect induced by clouds and smoke on forest net ecosystem productivity in central Siberia [PDF]

open access: yes, 2018
Aerosols produced by wildfires are a common phenomenon in boreal regions. For the Siberian taiga, it is still an open question if the effects of aerosols on atmospheric conditions increase net CO2 uptake or photosynthesis.
