摘要

古生态学不仅仅是一门古环境学科;这门科学非常适合为检验生态学假说提供必要的经验证据,并有助于我们理解生态学和进化的界面。在古生态学中,一个关键的时间框架是经常被忽视的q时间维度(几百年到几千年),它往往是研究生态-进化相互作用的最合适的时间维度。本文从概念的角度讨论了这些问题,并举例说明了古生态学对生态-进化相互作用研究的贡献。它还告诫研究人员忽视古生态学的威胁。具体而言,本文认为,随着基于dna的系统发育和系统地理研究越来越流行,对古生态学的忽视可能导致生态学及其与进化相互作用的经验支持的丧失。讨论的主要概念是时间连续体,生态古生态学的概念和面对更多假设方法的古生态学的经验性质。更实际地说,提供了几个例子,突出了生态古生态学在理解各种过程中的效用,包括生态演替,群落-环境平衡,群落组装,生物对环境变化的响应,物种形成和灭绝,以及生物多样性保护。生态-进化界面分析使用两个过程,其中这些学科相互作用密切:生态演替和远程迁移。本研究认为,生态古生态学(包括古DNA记录)和基于DNA的系统发育学和系统地理学都是更好地理解生物圈生态和发生在生态-进化界面的过程的必要条件。

Ecological palaeoecology: a missing link between ecology and evolution
Palaeoecology is more than a palaeoenvironmental discipline; it is a science that is well-suited for supplying the empirical evidence necessary to test ecological hypotheses and contributes to our understanding of the interface of ecology and evolution. A critical time frame in palaeoecology is the often-overlooked Q-time dimension (centuries to millennia), which tends to be the most appropriate time dimension to examine ecology–evolution interactions. This paper discusses these topics from a conceptual perspective and provides examples of the contributions of palaeoecology to the study of ecology–evolution interactions. It also admonishes researchers about the threats of overlooking palaeoecology. Specifically, this paper argues that the neglect of palaeoecology may result in the loss of empirical support for ecology and its interactions with evolution as DNA-based phylogenetic and phylogeographic studies become more and more prevalent. The main concepts discussed are the time continuum, the notion of ecological palaeoecology and the empirical nature of palaeoecology in the face of more hypothetical approaches. More practically speaking, several examples are provided that highlight the utility of ecological palaeoecology for understanding a variety of processes, including ecological succession, community– environment equilibria, community assembly, biotic responses to environmental change, speciation and extinction, and biodiversity conservation. The ecology–evolution interface is analysed using two processes in which these disciplines interact intensively: ecological succession and long-range migration. This work concludes that both ecological palaeoecology (including ancient DNA records) and DNA-based phylogenetics and phylogeography are needed to better understand the biosphere ecologically and the processes occurring at the ecology–evolution interface.
