Soils harbour highly-diverse invertebrate communities that play important roles for ecosystem services, including the mitigation of environmental pollution. Chemical stressors, such as pesticides, pharmaceuticals and metals, are being increasingly spread into ecosystems due to human activities. While it is crucial to predict the consequences of chemical stressors for soil biodiversity, chemical toxicity is often assessed using individuals or populations in laboratory cultures. There has been no systematic evaluation of the evidence documenting the impacts of chemical stressors on diverse, natural soil communities. Here, we use a comprehensive literature review of 274 studies to evaluate the current state of knowledge about the effects of chemicals on soil fauna communities. Most research has had limited spatial scope, with noteworthy gaps in the regions that are potentially the most threatened by soil pollution (Southern Hemisphere). Furthermore, reports generally were constrained to a few emblematic soil fauna groups (nematodes, collembola and earthworms) and chemical stressors (metals). Future research should address biases in spatial distribution of studies, as well as the taxonomic groups and chemical compounds considered. Specifically, emphasis on indirect effects mediated by species interactions, ecosystem functioning and interactive effects of stressors and climate change, currently lacking in the literature, is needed to improve soil-biodiversity conservation and restoration efforts, as well as predictions of global diversity change.

土壤动物多样性和化学压力源:知识差距回顾和未来研究路线图

土壤拥有高度多样化的无脊椎动物群落,它们在生态系统服务方面发挥着重要作用,包括减轻环境污染。由于人类活动,杀虫剂、药物和金属等化学压力源正越来越多地扩散到生态系统中。虽然预测化学压力对土壤生物多样性的影响至关重要,但通常使用实验室培养中的个体或群体来评估化学毒性。没有对记录化学压力源对多样化、自然土壤群落影响的证据进行系统评估。在这里,我们使用对 274 项研究的综合文献综述来评估有关化学品对土壤动物群落影响的当前知识状态。大多数研究的空间范围有限,在可能受土壤污染威胁最大的地区(南半球)存在显着差距。此外,报告通常仅限于少数具有象征意义的土壤动物群(线虫、弹尾虫和蚯蚓)和化学应激物(金属)。未来的研究应该解决研究空间分布的偏差,以及考虑的分类群和化合物。具体而言,需要强调目前文献中缺乏的物种相互作用、生态系统功能以及压力源和气候变化的相互作用所介导的间接影响,以改善土壤生物多样性保护和恢复工作,以及对全球多样性变化的预测。报告通常仅限于少数具有象征意义的土壤动物群(线虫、跳虫和蚯蚓)和化学应激物(金属)。未来的研究应该解决研究空间分布的偏差,以及考虑的分类群和化合物。具体而言,需要强调目前文献中缺乏的物种相互作用、生态系统功能以及压力源和气候变化的相互作用所介导的间接影响,以改善土壤生物多样性保护和恢复工作,以及对全球多样性变化的预测。报告通常仅限于少数具有象征意义的土壤动物群(线虫、跳虫和蚯蚓)和化学应激物(金属)。未来的研究应该解决研究空间分布的偏差,以及考虑的分类群和化合物。具体而言,需要强调目前文献中缺乏的物种相互作用、生态系统功能以及压力源和气候变化的相互作用所介导的间接影响,以改善土壤生物多样性保护和恢复工作,以及对全球多样性变化的预测。以及所考虑的分类群和化合物。具体而言,需要强调目前文献中缺乏的物种相互作用、生态系统功能以及压力源和气候变化的相互作用所介导的间接影响,以改善土壤生物多样性保护和恢复工作,以及对全球多样性变化的预测。以及所考虑的分类群和化合物。具体而言,需要强调目前文献中缺乏的物种相互作用、生态系统功能以及压力源和气候变化的相互作用所介导的间接影响,以改善土壤生物多样性保护和恢复工作,以及对全球多样性变化的预测。
