Dryland soils provide different societal and environmental services, such as food supply biodiversity support. In Europe, most of the dryland areas are devoted to agriculture. next decades, both European worldwide drylands expected suffer with increased intensity due climate change-derived rise in aridity. Many studies have focussed on aridity-induced changes major nutrients drylands, but littl...
Whereas warming enhances plant nutrient status and photosynthesis in most terrestrial ecosystems, dryland vegetation is vulnerable to the likely increases in evapotranspiration and reductions in soil moisture caused by elevated temperatures. Any warming-induced declines in plant primary production and cover in drylands would increase erosion, land degradation, and desertification. We conducted ...
Lagged precipitation effect explains a large proportion of annual aboveground net primary productivity in some dryland ecosystems. Using satellite-derived plant and datasets the Northern Hemisphere drylands during 2000–2018, we identify 1111 pixels mainly located Tibetan Plateau, western US, Kazakhstan where productivities are significantly correlated with previous-year (hereafter, lagged type)...
Global precipitation isoscapes based on the Global Network for Isotopes in Precipitation (GNIP) network are an important toolset that aid our understanding of global hydrologic cycles. Although the GNIP database is instrumental in developing global isoscapes, data coverage in some regions of hydrological interest (e.g., drylands) is low or non-existent thus the accuracy and relevance of global ...
Central Asia comprises a large fraction of the world’s drylands, known to be vulnerable to climate change. We analyzed the inter-annual trends and the impact of climate variability in the vegetation greenness for Central Asia from 1982 to 2011 using GIMMS3g normalized difference vegetation index (NDVI) data. In our study, most areas showed an increasing trend during 1982–1991, but experienced a...
AIM The global spread of woody plants into grasslands is predicted to increase over the coming century. While there is general agreement regarding the anthropogenic causes of this phenomenon, its ecological consequences are less certain. We analyzed how woody vegetation of differing cover affects plant diversity (richness and evenness) and multiple ecosystem functions (multifunctionality) in gl...
The drylands of the Middle East have been long seen not only as unfavourable to life, but also and relatedly, socio-politically fragile. Fraught with myths eternal ‘ethnic’, ‘sectarian’, or ‘res...
