Relationships between biodiversity and multiple ecosystem functions (that is, multifunctionality) are context-dependent. Both plant soil microbial diversity have been reported to regulate multifunctionality, but how their relative importance varies along environmental gradients remains poorly understood. Here, we relate multifunctionality across 130 dryland sites a 4,000 km aridity gradient in northern China. Our results show strong positive association species richness less arid regions,...
It is commonly believed that climate plays an important role in shaping the patterns of plant species richness. However, it remains unclear how may affect richness across large spatial scales and also over long-terms, for example massive arid regions during Quaternary into future. To fill this knowledge gap, we examined long-term trends vast drylands China based on our newly developed climate-species models. We first generated optimal random forest models relationships between current (CUR,...
Drought profoundly affects the morpho-physiological responses of desert plants in dryland. To scrutinize nitrogen (N)-fixing legumes ( Ammopiptanthus mongolicus , Caragana korshinskii ), N-fixing non-legumes Elaeagnus angustifolia Hippophae rhamnoides and non-N-fixing Nitraria tangutorum Haloxylon ammodendron ) under varied drought stress levels (75%, 50%, 25% 5% soil water holding capacity), a pot experiment was conducted greenhouse. Following prolonged deficit, carbon (C) N stoichiometry,...
Drylands are expected to be affected by greater global drought variability in the future; consequently, how dryland ecosystems respond events needs urgent attention. In this study, Normalized Vegetation Index (NDVI) and Standardized Precipitation Evaporation (SPEI) were employed quantify resistance of ecosystem productivity drylands northern China between 1982 2015. The relationships temporal trends characteristics, which included length, severity, interval, examined. responded greatest...
Alternative stable states refer to two or more in an ecosystem under the same external conditions. Ecosystems with alternative respond conditions changes nonlinearly and hysteretic, forward backward regime shifts occurring at different environmental levels (thresholds). The region between thresholds is unstable, eventual ecosystems state depends on initial mainly result from positive feedback generated by various biotic-biotic biotic-abiotic interactions ecosystem. For degraded state,...
The El Niño-Southern Oscillation (ENSO) alters ocean–atmosphere carbon exchange, but the mechanisms by which it affects air–sea flux (FCO2) remain unclear. Here, we used gridded FCO2 data from 2003 to 2021 elucidate control processes and regional differences in influence of ENSO on mid–low latitude Pacific Ocean. Overall, Ocean region was a net sink for CO2, with an average uptake rate −0.39 molC·m−2·year−1. Specifically, during La Niña period 2010–2012, absorption decreased 15.38%, while...
