摘要

The oribatid soil mite Oppia nitens C.L. Koch, 1836, is a model microarthropod in soil ecotoxicity testing. This species has a significant role in supporting soil functions and as a suitable indicator of soil contamination. Despite its significance to the environment and to ecotoxicology, however, very little is known of its biology, ecology, and suborganismal responses to contaminants in the soil. In the present review, we present detailed and critical insights into the biology and ecology of O. nitens in relation to traits that are crucial to its adaptive responses to contaminants in soil. We used a species sensitivity distribution model to rank the species sensitivity to heavy metals (cadmium and zinc) and neonicotinoids (imidacloprid and thiacloprid) compared with other standardized soil invertebrates. Although the International Organization for Standardization and Environment and Climate Change Canada are currently standardizing a protocol for the use of O. nitens in soil toxicity testing, we believe that O. nitens is limited as a model soil invertebrate until the molecular pathways associated with its response to contaminants are better understood. These pathways can only be elucidated with information from the mites' genome or transcriptome, which is currently lacking. Despite this limitation, we propose a possible molecular pathway to metal tolerance and a putative adverse outcome pathway to heavy metal toxicity in O. nitens.

Koch，1836年，是土壤生态毒性测试中的模型节肢动物。该物种在支持土壤功能和作为土壤污染的合适指标方面具有重要作用。尽管其对环境和生态毒理学具有重要意义，但对其生物学，生态学以及对土壤中污染物的亚生物响应却知之甚少。在当前的审查中，我们提出了与O.nitens的生物学和生态学相关的详细和批判性见解，这些特征对于对其对土壤污染物的适应性反应至关重要。与其他标准化土壤无脊椎动物相比，我们使用物种敏感度分布模型对物种对重金属（镉和锌）和新烟碱类（吡虫啉和噻虫啉）的敏感性进行排名。尽管加拿大国际标准化组织和环境与气候变化组织目前正在对在土壤毒性测试中使用O. nitens的协议进行标准化，但我们认为O. nitens作为模型土壤无脊椎动物是有限的，直到与其反应相关的分子途径更好地了解污染物。这些途径只能用螨虫的基因组或转录组信息来阐明，而这些信息目前尚缺乏。尽管有这个限制，我们提出了一种可能的金属耐受性分子途径和一个可能的不利于O. nitens重金属毒性的不良反应途径。 Environ Toxicol Chem 2019; 38：2593-2613。 （c）2019年SETAC
