Collembola have been proposed for several decades as a good organism’s model to survey soil biodiversity; but most of the studies focused on taxonomic endpoints. The main objectives of this study are to compare the effects of the different land uses, including urban and industrial land uses, while using both collembolan functional and taxonomic biodiversity approaches. We collected data on 3056 samples of Collembola communities across 758 sites in various land uses throughout France. The types of land use considered included all types of human activity from forestry to urban, industrial, traffic, mining and military areas, agricultural grassland, arable land, vineyards and urban vegetable gardens. In order to study functional and taxonomic biodiversity, we used community-weighted means, functional indices, species richness and density. When looking at collembolan functional diversity, urban and industrial soils appear clearly less diversified than when considering the taxonomic diversity. We suspect here a functional homogenization effect commonly reported in the literature for various organisms in urban ecosystems. Our study provides range of values for different taxonomic and functional indices of Collembola communities in a wide land use classification across France.

弹尾纲的功能和分类多样性作为评估土地利用对土壤生物多样性影响的补充工具

几十年来，弹尾目一直被认为是调查土壤生物多样性的良好生物模型。但大多数研究都集中在分类学终点上。本研究的主要目标是比较不同土地利用的影响，包括城市和工业土地利用，同时使用弹跳虫功能和分类生物多样性方法。我们在法国各地不同土地用途的 758 个地点收集了 3056 个弹尾虫群落样本的数据。考虑的土地利用类型包括从林业到城市、工业、交通、采矿和军事地区、农业草地、耕地、葡萄园和城市菜园的所有类型的人类活动。为了研究功能和分类生物多样性，我们使用了群落加权平均值、功能指数、物种丰富度和密度。在研究弹尾目功能多样性时，城市和工业土壤的多样性明显低于考虑分类多样性时的多样性。我们在这里怀疑城市生态系统中各种生物的文献中普遍报道的功能同质化效应。我们的研究为法国广泛的土地利用分类中弹尾目群落的不同分类和功能指数提供了一系列值。
