The increase in phosphorus (P) and nitrogen (N) inputs, as well soil acidification resulting from multiple environmental changes, has profound effects on the attributes of plant biota communities, ecosystem functions. However, how these community impact multifunctionality (EMF) its stability under changes remains unclear. By integrating datasets over four consecutive years an experiment with enrichments N P a semiarid grassland Mongolian Plateau, we explored (species richness, asynchrony, compositional temporal stability) plants (bacteria, fungi, nematodes) their associations EMF stability. showed opposite responses to nutrient enrichment non-acidification conditions. Soil had more significant effect biota, components stability, than enrichment. decreased both mean EMF, while increased EMF. did not have but positive interactive We also found that richness asynchrony determined co-regulate changes. These findings highlight urgent need protect biodiversity maintain especially for ecosystems undergoing

Long-term observations have shown that structure and function of grasslands changed due to climate change over the past decades. However, little is known about how respond along precipitation gradient, potential mechanisms remain elusive. Here, we utilize a long-term experiment in typical steppe explore universal differential community functional groups assembly gradient. Our results indicated sensitivity was related local precipitation. The strength positive effects on aboveground biomass, species richness, their relationship decreased modestly with mechanism behind this plant composition precipitation-induced, annuals more responsive as increased Furthermore, current both drove group assembly, role diminished increasing Among them, fluctuation, average were most critical indicators affecting low, medium high sites, respectively. In conclusion, climatic do not always exert identical This could be importance for improving our ability predict future changes grassland ecosystems.

Abstract Nitrogen is the second limited factor in arid regions. Little information available on soil N cycling and availability under grazing regions, which required to evaluate land‐use management with respect dynamics. In 2011, we established a rotational field experiment grassland. We conducted experiments explore effects of herbivores net mineralization processes via changes temperature, moisture, pH, microbial biomass nitrogen (MBN) 2016 2017. Our results showed that did not alter because higher moisture MBN had positive negative mineralization, thereby balancing mineralization. Plant uptake at plots was, nevertheless, 23% than non‐grazing plots. These demonstrated potentially improved inorganic alleviated limitation Soil nitrification was main pathway transformation Grazing accumulation NO 3 − content, resulting environmental problems (such as 2 O emission leaching); however, little effect (~15% increase) leaching (~7% decrease) emission. reflect important mechanisms resilience ecosystem stability an N‐limited environment. provide perspective for grassland management, aiming maintain supplying capacity annual pasture sustainably. Overall, our study suggests effective practice sustainable usage local grasslands, it improves physicochemical biological properties, which, turn, increases supply.
