SPATIO-TEMPORAL VARIATIONS OF SOIL WATER USE IN THE GROWING SEASON IN NORTHEAST CHINA USING MODIS DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Water use efficiency is known as an important indicator of carbon and water cycle and reflects the transformation capacity of vegetation water and nutrients into biomass. In this study, we presented a new indicator of water use efficiency, soil water use

The Effect of Crop Diversification and Season on Microbial Carbon Use Efficiency Across a European Pedoclimatic Gradient

open access: yesEuropean Journal of Soil Science
Microbial transformation of soil organic matter plays a critical role in carbon (C) cycling making it essential to understand how land use and management practices influence microbial physiology and its connection to C dynamics. One factor that is likely

A model-based constraint on CO2 fertilisation [PDF]

open access: yes, 2013
We derive a constraint on the strength of CO2 fertilisation of the terrestrial biosphere through a “top-down” approach, calibrating Earth system model parameters constrained by the post-industrial increase of atmospheric CO2 concentration.

Functional indicators of response mechanisms to nitrogen deposition, ozone, and their interaction in two Mediterranean tree species [PDF]

open access: yes, 2017
The effects of nitrogen (N) deposition, tropospheric ozone (O3) and their interaction were investigated in two Mediterranean tree species, Fraxinus ornus L. (deciduous) and Quercus ilex L.

Nitrogen availability and summer drought, but not N:P imbalance, drive carbon use efficiency of a Mediterranean tree‐grass ecosystem

open access: yesGlobal Change Biology
All ecosystems contain both sources and sinks for atmospheric carbon (C). A change in their balance of net and gross ecosystem carbon uptake, ecosystem‐scale carbon use efficiency (CUEECO), is a change in their ability to buffer climate change.

Biomass production and management practices in mixed crop-livestock systems in the west African Sahel: Opportunities and constraints [PDF]

open access: yes, 2020
The Sahel is characterized by a marked inter-annual climate variability and has experienced a number of food security crises following the severe droughts during the 1970s and 1980s.

Urban pollution and ecosystem services [PDF]

open access: yes, 2019
Urban pollutants can degrade and inhibit ecological functions and processes. Those natural processes provide vital benefits and services to humans.

Water use strategies of sparse vegetation in the desertification area determine the future trends of afforestation

open access: yesApplied Water Science
Water use strategies of sparse vegetation are significant for understanding carbon water cycle processes in the desertification area. Afforestation is controversial in terms of the vegetation growth and water consumption trade-offs.
