Land-use intensification to increase yields is often detrimental to biodiversity undermining the provision of ecosystem services. However, it is questionable if ecosystem service providers contribute to ecological intensification by achieving the same or higher yields than conventional high-intensity agriculture.
In this study, we aimed to disentangle the effects of local and landscape-scale land-use intensification on arthropod communities and their contribution to ecosystem services and crop yield. A set of meta-analytic structural equation models allowed us to assess direct and indirect relationships in the cascade from land use to yield.
We selected 37 datasets containing information on land use, community composition, levels of pollination and natural pest control services, and crop yield. We quantified functional diversity of communities by collecting trait information for three exemplary groups of service-providers: bees, ground beetles, and spiders.
Local land-use intensification reduced the abundance of all arthropod groups. Spiders were the only group whose species richness was negatively related to a higher percentage of arable land in the landscape. High abundance of bees related positively to oilseed rape pollination and crop yields. In the models for the two predator groups, crop yield was strongly determined by land use, independent of the pest control services provided by natural enemies.
Our results suggest a potential for ecological intensification mediated by land-use change in crops where pollination benefits yield, but suggest more nuanced effects for pest control. Our study also calls for experiments on multiple taxonomic groups and ecosystem services that apply comparable methods at similar scales.

为提高产量而进行的土地利用集约化往往对生物多样性有害,破坏了生态系统服务的提供。然而,生态系统服务提供者是否通过实现与传统高强度农业相同或更高的产量来促进生态集约化,这是值得怀疑的。
在本研究中,我们旨在厘清局部和景观尺度的土地利用集约化对节肢动物群落的影响及其对生态系统服务和作物产量的贡献。一组元分析结构方程模型使我们能够评估从土地利用到产量的级联中的直接和间接关系。
我们选择了37个数据集,其中包含有关土地利用、群落组成、授粉水平和自然虫害控制服务以及作物产量的信息。我们通过收集三类示例性服务提供者(蜜蜂、地甲虫和蜘蛛)的性状信息来量化群落的功能多样性。
局部土地利用集约化降低了所有节肢动物类群的丰度。蜘蛛是唯一物种丰富度与景观中更高比例的耕地呈负相关的类群。蜜蜂的高丰度与油菜授粉和作物产量呈正相关。在两个捕食者类群的模型中,作物产量强烈取决于土地利用,而与天敌提供的虫害控制服务无关。
我们的结果表明,在授粉有益于产量的作物中,土地利用变化介导的生态集约化具有潜力,但对虫害控制的影响更为细微。我们的研究还呼吁对多个分类群和生态系统服务进行实验,这些实验应在相似尺度上采用可比方法。
