Abstract

Larger soil organisms have often been reported as the most sensitive to disturbances caused by cropping practices. However, soil macrofauna comprises groups with a wide diversity of morphological and ecological features, which may respond differently to applied practices. In order to further assess the effect of cropping systems on soil macrofauna, macrofauna organisms were extracted from soil blocks over 21 fields (each comprising three plots) located in the Paris basin, in autumns 2020 and 2021. Fields belonged to conventional, conservation or organic systems, either long-established (≥ 7 years) or in transition (≤ 3 years). Tillage, pesticide treatment and organic matter input intensity were assessed in each field using composite indexes of practice intensity. Macrofauna density and diversity, earthworm ecological categories, species richness and functional traits were investigated. Our results showed that the density and diversity of macrofauna demonstrated few differences regarding different cropping systems, with highly variable effects across groups and years. Specific macroarthropod groups responded differently to tillage, pesticide treatment and organic input intensity, but not over the two years of the study. Regarding earthworms, high tillage intensity had a negative effect on the density and biomass of epi-anecic juveniles and on species with a small body size. Higher organic matter inputs had a negative effect on the density and biomass of endogeic earthworms, and could be related to several earthworm functional traits (body length, mass/length ratio, carbon preferences). Effects of pesticide treatments were less clear, although they could have impacted some earthworm species. More generally, taxonomic and functional trait approaches of earthworm community led to similar conclusions. Overall, our results support the need to account for (i) the actual intensity of practices in cropping systems and (ii) the different taxonomic, trophic and ecological groups of macrofauna, in order to assess the effects of cropping systems on soil biodiversity.

耕作制度与土壤大型动物之间的复杂关系：耕作强度、分类群和性状的影响

据报道，大型土壤生物往往对耕作方式造成的干扰最为敏感。然而，土壤大型动物包括形态和生态特征多种多样的群体，它们可能会对耕作方式做出不同的反应。为了进一步评估耕作制度对土壤大型动物的影响，我们在 2020 年和 2021 年秋季从位于巴黎盆地的 21 块田地（每块田地包括三个地块）的土壤块中提取了大型动物有机体。这些田块属于常规、保护或有机系统，有的已种植多年（≥ 7 年），有的处于过渡期（≤ 3 年）。采用耕作强度综合指数评估每块田的耕作、农药处理和有机物投入强度。对大型动物的密度和多样性、蚯蚓生态类别、物种丰富度和功能特征进行了调查。结果表明，大型底栖动物的密度和多样性在不同耕作制度下几乎没有差异，不同组别和年份之间的影响差异很大。特定的大型节肢动物群对耕作、杀虫剂处理和有机投入强度的反应不同，但在研究的两年中并无差异。在蚯蚓方面，高耕作强度对蚯蚓幼虫和小体型物种的密度和生物量有负面影响。较高的有机物投入对内生蚯蚓的密度和生物量有负面影响，这可能与蚯蚓的几种功能特征（体长、质量/长度比、碳偏好）有关。杀虫剂处理的影响不太明显，尽管它们可能会对某些蚯蚓物种产生影响。总体而言，蚯蚓群落的分类学和功能特征方法得出了相似的结论。总之，我们的研究结果表明，在评估种植系统对土壤生物多样性的影响时，需要考虑到：(i) 种植系统中的实际耕作强度；(ii) 大型动物的不同分类、营养和生态群落。

期刊介绍： Pedobiologia publishes peer reviewed articles describing original work in the field of soil ecology, which includes the study of soil organisms and their interactions with factors in their biotic and abiotic environments. Analysis of biological structures, interactions, functions, and processes in soil is fundamental for understanding the dynamical nature of terrestrial ecosystems, a prerequisite for appropriate soil management. The scope of this journal consists of fundamental and applied aspects of soil ecology; key focal points include interactions among organisms in soil, organismal controls on soil processes, causes and consequences of soil biodiversity, and aboveground-belowground interactions. We publish: original research that tests clearly defined hypotheses addressing topics of current interest in soil ecology (including studies demonstrating nonsignificant effects); descriptions of novel methodological approaches, or evaluations of current approaches, that address a clear need in soil ecology research; innovative syntheses of the soil ecology literature, including metaanalyses, topical in depth reviews and short opinion/perspective pieces, and descriptions of original conceptual frameworks; and short notes reporting novel observations of ecological significance.
