Terrestrial and fluvial carbon fluxes in a tropical watershed: Nyong basin, Cameroon [PDF]

open access: yes, 2009
The Nyong watershed, with an area of 27 800 km2 and a mean annual discharge of 390 m3 s−1, is the second largest river in Cameroon. The Nyong watershed serves as an outstanding study area for the examination of carbon fluxes in humid tropical ...

Global variability of carbon use efficiency in terrestrial ecosystems

open access: yes, 2019
. Vegetation carbon use efficiency (CUE) is a key measure of carbon (C) transfer from the atmosphere to terrestrial biomass, and indirectly reflects how much C is released through autotrophic respiration from the vegetation to the atmosphere.

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 ...

Exploring climate–ecological driving mechanisms of vegetation change in central asia: a hierarchical assessment framework based on trend tests, multiple regression, and structural equation modeling

open access: yesGeomatics, Natural Hazards & Risk
The climate-ecological mechanisms driving vegetation dynamics in the ecologically fragile ecosystems of Central Asia remain insufficiently understood, particularly under accelerating climate change.

Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds

open access: yes, 2007
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be photosynthesis, particularly photosynthesis that has evolved with a ...

Water Use Efficiency Spatiotemporal Change and Its Driving Analysis on the Mongolian Plateau

open access: yesSensors
Water use efficiency (WUE) connects two key processes in terrestrial ecosystems: the carbon and water cycles. Thus, it is important to evaluate temporal and spatial changes in WUE over a prolonged period.

Response of vegetation carbon use efficiency to drought: A case study of the Manas River Basin in Xinjiang

open access: yes
Abstract Carbon Use Efficiency (CUE) – defined as the ratio of net to gross primary production (NPP/GPP) – is a critical regulator of ecosystem carbon sequestration. Focusing on the Manas River Basin (Xinjiang, China), a typical arid endorheic basin, we analyzed CUE dynamics across four ecosystems (coniferous forest, broadleaf forest, grassland,

On the importance of including vegetation dynamics in Budyko's hydrological model [PDF]

open access: yes, 2015
The Budyko curve describes the patterns observed between between climate, evapotranspiration and run-off and has proven to be a useful model for predicting catchment energy and water balances.

Opposite responses of water use efficiency and carbon use efficiency to agricultural drought during winter wheat growth period in the core area of grain production in the ancient course of Yellow River

open access: yesAgricultural Water Management
In the context of global climate change, agricultural drought threatens food security in the ancient course of Yellow River, a key grain production region in China.
