Abstract

Aim

Anthropogenic-driven biodiversity loss can impact ecosystem stability. However, most studies have only evaluated the diversity–stability relationship at the local scale and we do not fully understand which factors stabilize animal populations and communities across scales. Here, we investigate the role of species dispersal ability, climate, spatial distance and different facets of biodiversity on the stability of butterfly populations and communities across multiple spatial scales.

Location

Primarily Western Europe.

Time Period

2005–2016.

Major Taxa Studied

Butterflies (Rhopalocera) of Europe.

Methods

We assembled a continent-wide database of European butterflies' abundance and used Structural Equation Modelling to evaluate the direct and indirect effects of multiple stabilizing mechanisms. In parallel, we tested the effect of dispersal ability on the stability at multiple spatial scales, using a butterfly mobility index as an indicator of dispersal capacity.

Results

Regional stability strongly reflected local stability, which in turn was driven by both taxonomic and functional α-diversity. Spatial asynchrony was also important for regional stability and it was driven by both functional β-diversity and metapopulation asynchrony, which in turn increased with spatial distance among communities. We observed a positive effect of temperature on functional α-diversity and on local stability, whereas precipitation negatively influenced local diversity. Finally, spatial asynchrony contributed more to the regional stability of less mobile species compared to highly mobile ones, indicating that both extrinsic and intrinsic determinants of connectivity impact regional stability indirectly.

Main Conclusions

Our results demonstrate the importance of local and regional processes for regional stability. However, the relative contribution of spatial asynchrony and metapopulation asynchrony increases with connectivity loss, especially for less mobile species, indicating that landscape management should be tailored depending on the dispersal capacity of organisms. Both local biodiversity loss and regional biotic homogenization destabilize metacommunities, with potential implications for the reliable provision of ecosystem functions.

连通性和气候影响欧洲蝴蝶元群落跨空间尺度的多样性-稳定性关系

目的人为因素导致的生物多样性丧失会影响生态系统的稳定性。然而，大多数研究仅评估了局部尺度的多样性与稳定性之间的关系，我们并不完全了解哪些因素可以稳定跨尺度的动物种群和群落。在此，我们研究了物种扩散能力、气候、空间距离和生物多样性的不同方面对跨空间尺度的蝴蝶种群和群落稳定性的作用。方法我们建立了一个欧洲蝴蝶丰度的全洲数据库，并使用结构方程模型评估了多种稳定机制的直接和间接影响。同时，我们使用蝴蝶流动性指数作为分散能力的指标，测试了分散能力在多个空间尺度上对稳定性的影响。结果区域稳定性强烈反映了地方稳定性，而地方稳定性又是由分类学和功能α多样性驱动的。空间异步性对区域稳定性也很重要，它受功能β多样性和元种群异步性的影响，而功能β多样性和元种群异步性又随群落间空间距离的增加而增加。我们观察到温度对功能α多样性和地区稳定性有积极影响，而降水对地区多样性有消极影响。最后，与高流动性物种相比，空间非同步性对低流动性物种的区域稳定性贡献更大，这表明连通性的外在和内在决定因素对区域稳定性都有间接影响。然而，空间异步性和元种群异步性的相对贡献会随着连通性的丧失而增加，尤其是对于流动性较低的物种而言，这表明景观管理应根据生物的扩散能力而量身定制。局部生物多样性丧失和区域生物同质化都会破坏元群落的稳定性，从而对生态系统功能的可靠提供产生潜在影响。

期刊介绍： Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
