Abstract
Chemical pollution can threaten biodiversity at different levels, from genetically diverse populations (genetic diversity) to different species (species diversity) and ecosystem traits/interactions (functional diversity). Most assessments of chemical impacts on different biodiversity levels depend on wet lab and field experiments, including sequencing large numbers of organisms, environmental DNA approaches, single chemical–species–outcome toxicity tests, and trait-based methods. However, it is impossible to assess all chemicals, species, populations, and ecosystems using these methods. Therefore, we advocate that computational methods are necessary to characterize, quantify, and predict chemical impacts on biodiversity. We briefly introduce the current state of research into chemical impacts on genetic diversity, species diversity, and functional diversity and describe new opportunities for computational methods like data integration, machine learning, cross-species/cross-ecosystem extrapolation, adverse outcome pathways, and Bayesian methods to support research in these three areas. By harnessing data and methods currently at our disposal and preparing methods to take advantage of continuously emerging data sets, computational approaches can be paired with environmental monitoring so different levels of biological organization can serve as consecutive warning signs for chemical impacts on biodiversity. This will enable effective ecosystem protection measures to be better developed and implemented to prevent biodiversity loss from chemical pollution.
化学污染可在不同层面威胁生物多样性,从基因多样性种群(遗传多样性)到不同物种(物种多样性)和生态系统特征/相互作用(功能多样性)。大多数有关化学品对不同生物多样性水平影响的评估都依赖于湿实验室和现场实验,包括对大量生物进行测序、环境 DNA 方法、单一化学品-物种-结果毒性测试以及基于性状的方法。然而,使用这些方法不可能对所有化学品、物种、种群和生态系统进行评估。因此,我们主张必须采用计算方法来描述、量化和预测化学品对生物多样性的影响。我们简要介绍了化学物质对遗传多样性、物种多样性和功能多样性影响的研究现状,并描述了数据整合、机器学习、跨物种/跨生态系统外推法、不利结果途径和贝叶斯方法等计算方法的新机遇,以支持这三个领域的研究。通过利用我们目前掌握的数据和方法,并准备好利用不断涌现的数据集的方法,可以将计算方法与环境监测结合起来,这样不同层次的生物组织就可以作为化学品对生物多样性影响的连续预警信号。这样就能更好地制定和实施有效的生态系统保护措施,防止化学污染造成生物多样性的丧失。
