DNA can be preserved in marine and freshwater sediments both in bulk sediment and in intact, viable resting stages. Here, we assess the potential for combined use of ancient, environmental, DNA and timeseries of resurrected long-term dormant organisms, to reconstruct trophic interactions and evolutionary adaptation to changing environments. These new methods, coupled with independent evidence of biotic and abiotic forcing factors, can provide a holistic view of past ecosystems beyond that offered by standard palaeoecology, help us assess implications of ecological and molecular change for contemporary ecosystem functioning and services, and improve our ability to predict adaptation to environmental stress.
DNA 可以在海洋和淡水沉积物中得到保存，无论是在整体沉积物中还是在完整的、有活力的休眠阶段中。在这里，我们评估了结合使用古代环境 DNA 和长期休眠生物复活的时间序列数据，以重建营养相互作用和对环境变化的进化适应的潜力。这些新方法，加上生物和非生物胁迫因素的独立证据，可以提供比标准古生态学更全面的过去生态系统的视图，帮助我们评估生态和分子变化对当代生态系统功能和服务的影响，并提高我们预测适应环境压力的能力。
