Diurnal pattern and characteristic of soil respiration and net ecosystem carbon exchange in alpine meadow ecosystem on the northeastern Qinghai-Tibet Plateau

Ecological Indicators
Analyzing the diurnal pattern of soil respiration is essential for understanding the potential mechanisms of carbon cycle. Additionally, long-term and high temporal frequency soil respiration observations are crucial and valuable at different time scales,

Longer growing seasons do not increase net carbon uptake in Northeastern Siberian tundra [PDF]

With global warming, snowmelt is occurring earlier and growing seasons are becoming longer around the Arctic. It has been suggested that this would lead to more uptake of carbon due to a lengthening of the period in which plants photosynthesize.

Net Ecosystem Exchange of CO2 in Deciduous Pine Forest of Lower Western Himalaya, India

Resources, 2019
Carbon cycle studies over the climate-sensitive Himalayan regions are relatively understudied and to address this gap, systematic measurements on carbon balance components were performed over a deciduous pine forest with an understory layer.

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

New 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.

Understanding the effect of disturbance from selective felling on the carbon dynamics of a managed woodland by combining observations with model predictions [PDF]

, 2017
The response of forests and terrestrial ecosystems to disturbance is an important process in the global carbon cycle in the context of a changing climate.

Assessing biogeochemical effects and best management practice for a wheat–maize cropping system using the DNDC model [PDF]

, 2014
Contemporary agriculture is shifting from a single-goal to a multi-goal strategy, which in turn requires choosing best management practice (BMP) based on an assessment of the biogeochemical effects of management alternatives.

Growing season net ecosystem CO₂ exchange of two desert ecosystems with alkaline soils in Kazakhstan

Ecology and Evolution, 2013
AbstractCentral Asia is covered by vast desert ecosystems, and the majority of these ecosystems have alkaline soils. Their contribution to global net ecosystem CO2 exchange (NEE) is of significance simply because of their immense spatial extent. Some of the latest research reported considerable abiotic CO2 absorption by alkaline soil, but the rate of ...

Upscaling fluxes from towers to regions, continents and global scales using datadriven approaches [PDF]

, 2011
Quantifying the current carbon cycle of terrestrial ecosystems requires that we translate spatially sparse measurements into consistent, gridded flux estimates at the regional scale.
