化石记录提供了生物多样性在进化时间尺度上的时间趋势的唯一直接证据。然而，利用化石记录进行的生物多样性研究很大程度上局限于分类学和/或形态多样性的讨论。可能受到强烈选择的行为和生理特征在很大程度上被身体化石记录所掩盖。类似的问题也存在于动物难以接近的现代生态系统中。在这篇综述中，我们阐述了那些研究深层时间和难以到达的现代生态系统中的行为生态学的人之间共享的一些共同的概念和方法论基础。我们讨论了用于探索种群连通性和遗传漂变、生活史特征和野外代谢率的新兴生态地球化学方法，并讨论了与深度应用这些方法相关的一些其他问题。
The fossil record provides the only direct evidence of temporal trends in biodiversity over evolutionary timescales. Studies of biodiversity using the fossil record are, however, largely limited to discussions of taxonomic and/or morphological diversity. Behavioural and physiological traits that are likely to be under strong selection are largely obscured from the body fossil record. Similar problems exist in modern ecosystems where animals are difficult to access. In this review, we illustrate some of the common conceptual and methodological ground shared between those studying behavioural ecology in deep time and in inaccessible modern ecosystems. We discuss emerging ecogeochemical methods used to explore population connectivity and genetic drift, life-history traits and field metabolic rate and discuss some of the additional problems associated with applying these methods in deep time.
