植物科学与地球科学的结合为开发和测试从机械角度理解的过去大气变化的古植物学监测器和记录器（古代用指标）提供了机会，并在遗传层面上确定和理解了基础反应。这篇评论强调了这种方法是如何被用来提供两个不同的古代理。第一个是基于气孔（在树叶表面发现的呼吸孔）和大气CO2浓度之间的负相关关系;第二个是基于跟踪花粉和孢子组成中的化学变化，以重建地球表面UV B辐射通量的变化，并由此推断与大火成岩省喷发和就位有关的平流层过程的变化。在这里，我们强调了一种新的快速，廉价的化学分析技术与现有的，强大的孢粉学方法相结合的潜力，打开了大门，通过古生物学记录更深入地了解过去的环境。展望未来，太阳辐射和二氧化碳浓度相结合的方法可以很容易地应用于整个地质记录。
The integration of plant and Earth sciences offers the opportunity to develop and test palaeobotanical monitors and recorders (palaeoproxies) of past atmospheric change that are understood from a mechanistic perspective, with the underpinning responses being identified and understood at the genetic level. This review highlights how this approach has been used to deliver two distinct palaeoproxies. The first is based on the negative relationship between stomata (breathing pores found on the leaf surface) and atmospheric CO2 concentration; the second is based on tracking chemical changes seen in the composition of pollen and spores to reconstruct changes in the flux of UV‐B radiation on the Earth's surface and from this infer changes in stratospheric processes linked to the eruption and emplacement of Large Igneous Provinces. Here, we highlight the potential of integrating a new rapid, inexpensive chemical analysis technique with existing, robust palynological methods, opening the door to a deeper understanding of past environments via the palaeobiological record. A look to the future suggests a combined solar radiation–CO2 concentration approach could be readily applied across the geological record.
