随着全球生物多样性的迅速丧失, 生物多样性与生态系统稳定性的关系已成为人类面临的重要
科学问题. 许多研究表明生物多样性与稳定性存在正相互关系, 但其内在机制尚不能被很好地 …

Human land use may detrimentally affect biodiversity, yet long-term stability of species
communities is vital for maintaining ecosystem functioning. Community stability can be …

Biodiversity generally promotes ecosystem stability. To assess whether the diversity–stability
relationship observed under ambient nitrogen (N) conditions still holds under N enriched …

Past global change studies have identified changes in species diversity as a major
mechanism regulating temporal stability of production, measured as the ratio of the mean to …

Primary data from 262 pastoral households in Inner Mongolia are analyzed to determine the
effects of a subsidy for grassland protection on livestock numbers, grazing intensity, and …

Background and aims Global nitrogen enrichment has been identified as a major
environmental problem that poses a threat to ecosystem functioning. However, there is no …

Soil biota could have a significant impact on plant productivity and diversity through
benefiting plants and mediating plant–plant interaction. However, it is poorly understood …

Purpose Nitrification and denitrification, two of the key nitrogen (N) transformation processes
in the soil, are carried out by a diverse range of microorganisms and catalyzed by a series of …

We used a seven-year urea gradient applied field experiment to investigate the effects of
nitrogen (N) applications on soil N hydrolytic enzyme activity and ammonia-oxidizing …

Plant community structure responds strongly to anthropogenic disturbances, which greatly
influence community stability. The changes in community structure, aboveground biomass …
