在人为压力增加的情况下，了解社区稳定的驱动因素是一个紧迫的问题。生物多样性可以促进群落稳定，但生物多样性-稳定性关系的研究很少考虑生物多样性变化的全部复杂性。此外，由于大多数研究的分类、空间和时间范围都很狭窄，因此寻找跨分类组和空间和时间尺度的共性仍然具有挑战性。我们使用通过国家生态观测网络(NEON)在美国各地收集的生物数据，评估了四个分类类别：小型哺乳动物、地面甲虫、鱼类和淡水大型无脊椎动物的群落稳定性和生物多样性变化之间的联系。我们将群落稳定性定义为聚集物种丰富度的恒定。我们将生物多样性的变化量化为(1)群落分类和功能组成的不同，以及物种更替和丰富度变化的不同部分，以及(2)物种丰度分布的变化，如物种等级、丰富度和均匀度的变化。我们发现，群落稳定性随着物种更替和物种更替对总体差异的贡献而增加，但随着物种丰富度和均匀度的增加而下降。这与物种丰度的时间波动有助于稳定群落属性的概念是一致的。我们还发现，在每个群落的分类组成重新洗牌的情况下，当群落功能组成的变化低于或高于预期时，群落稳定性最高。这表明，长期的群落稳定可能是由于功能相似的物种在高度分类重新洗牌的组合中的波动所致。相反，波动物种的功能独特性补偿了较低的分类重新洗牌，以推动群落性质的稳定。我们的研究提供了群落稳定性和生物多样性变化之间关系的初步评估，并说明了跨生态系统和生物群落收集的精细时间分辨率数据在理解生物多样性-稳定性关系的一般机制方面的作用。
Understanding the drivers of community stability in times of increasing anthropogenic pressure is an urgent issue. Biodiversity is known to promote community stability, but studies of the biodiversity–stability relationship rarely consider the full complexity of biodiversity change. Furthermore, finding generalities that hold across taxonomic groups and spatial and temporal scales remains challenging because most investigations have narrow taxonomic, spatial, and temporal scopes. We used organismal data collected through the National Ecological Observatory Network (NEON) at sites across the contiguous United States to evaluate linkages between community stability and biodiversity change for four taxonomic groups: small mammals, ground beetles, fish, and freshwater macroinvertebrates. We defined community stability as constancy of aggregate species' abundance. We quantified change in biodiversity as (1) dissimilarity in community taxonomic and functional composition and species replacement and richness change components of that dissimilarity and (2) change in species' abundance distributions as captured by change in species rank, richness, and evenness. We found that community stability increased with species replacement and with contribution of species replacement to overall dissimilarity for all taxonomic groups, but declined with increasing change in species richness and evenness. This is consistent with the notion that temporal fluctuations in species abundance can help stabilize community properties. We also found that community stability was highest when change in community functional composition was either lower or higher than expected given reshuffling of each community's taxonomic composition. This suggests that long‐term community stability can result from fluctuations of functionally similar species in assemblages with high taxonomic reshuffling. On the contrary, the functional uniqueness of fluctuating species compensates for lower taxonomic reshuffling to drive stabilization of community properties. Our study provides an initial assessment of the relationship between community stability and biodiversity change and illustrates the utility of fine temporal resolution data collected across ecosystems and biomes to understand the general mechanisms underlying biodiversity–stability relationships.
