Spatial variations and controls of carbon use efficiency in China’s terrestrial ecosystems

Scientific Reports, 2019
Carbon use efficiency (CUE), one of the most important eco-physiological parameters, represents the capacity of plants to transform carbon into new biomass. Understanding the variations and controls of CUE is crucial for regional carbon assessment. Here,

Land-use change drives soil organic carbon losses in a temperate montane forest ecosystem

Discover Soil
Forests represent essential global carbon stocks; however, their storage capacity is diminishing due to deforestation, degradation, and land-use changes driven by anthropogenic activities.

Monitoring Spatio-Temporal Changes of Terrestrial Ecosystem Soil Water Use Efficiency in Northeast China Using Time Series Remote Sensing Data

Sensors, 2019
Soil water use efficiency (SWUE) was proposed as an effective proxy of ecosystem water use efficiency (WUE), which reflects the coupling of the carbon–water cycle and function of terrestrial ecosystems. The changes of ecosystem SWUE at the regional

The use of chronosequences in studies of ecological succession and soil development [PDF]

, 2010
1. Chronosequences and associated space-for-time substitutions are an important and often necessary tool for studying temporal dynamics of plant communities and soil development across multiple time-scales.

Spatial-Temporal Variations in the Climate, Net Ecosystem Productivity, and Efficiency of Water and Carbon Use in the Middle Reaches of the Yellow River

Remote Sensing
An accurate assessment of the spatial–temporal variations in regional net ecosystem productivity (NEP), water use efficiency (WUE), and carbon use efficiency (CUE) are vital for understanding the water–carbon cycle.

Simulation of Vegetation Maximum Light Use Efficiency and Improvement of the CASA Model Based on Elevated Atmospheric CO2 Concentrations

Shuitu Baochi Xuebao
[Objective] In order to accurately estimate net primary productivity (NPP) of vegetation under the context of rising atmospheric CO2 concentrations. [Methods] A CO2 concentration factor was introduced into the Carnegie-Ames-Stanford Approach (CASA) model

Plant community responses to warming modified by soil moisture in the Tibetan Plateau

Arctic, Antarctic, and Alpine Research, 2020
Predicted warming in Tibetan Plateau may have profound effects on plant community structure and function. We used open-top chambers to artificially warm two different plant communities in Tibet from 2012 to 2016.

Forest Stand Structure and Primary Production in relation to Ecosystem Development, Disturbance, and Canopy Composition [PDF]

, 2016
Temperate forests are complex ecosystems that sequester carbon (C) in biomass. C storage is related to ecosystem-scale forest structure, changing over succession, disturbance, and with community composition.

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool
