我们使用一个通用的定量框架-价格方程-分区表型响应环境变化到单独的生理，进化和生态组件。我们演示了这些响应，这可能会发生在不同的时间尺度，通常是孤立的研究，可以结合在一个添加剂的方式，我们讨论这样做的主要优点。我们说明我们的方法使用两个工作的例子，关于微生物群落内毒素抗性的出现，和海洋浮游植物在高CO2环境中的碳吸收的估计。我们发现，这种方法使我们能够排除特定的机制假设社区层面的转变，并确定具体的情况下，缺乏适当的数据。因此，普赖斯方程不仅提供了一个强有力的概念帮助，而且也是检验假设和指导经验研究方案的一种手段。
We use a general quantitative framework - the Price equation - to partition phenotypic responses to environmental change into separate physiological, evolutionary and ecological components. We demonstrate how these responses, which potentially occur over different timescales and are usually studied in isolation, can be combined in an additive way; and we discuss the main advantages of doing this. We illustrate our approach using two worked examples, concerning the emergence of toxin resistance within microbial communities, and the estimation of carbon uptake by marine phytoplankton in high-CO2 environments. We find that this approach allows us to exclude particular mechanistic hypotheses with regard to community-level transformations, and to identify specific instances where appropriate data are lacking. Thus Price's equation provides not only a powerful conceptual aid, but also a means for testing hypotheses and for directing empirical research programmes.
