提出的协议显示了对化石叶上连续叶片面貌特征的数字测量和分析,以使用数字叶面貌和单位面积的叶质量重建方法重建古气候和古生态学。
我们的研究重点是了解现代植物植物性状与气候和生态之间的关系。然后利用这些关系,我们可以开发代理或模型,用于重建古代植物群落的气候和生态。最近的研究集中在了解当今和过去植物性状与气候和生态之间关系的生物学、生理学、进化基础。
这项研究表明,植物性状对气候和生态做出反应,无论是在单一植物的生命周期还是在进化时间尺度上。我们的研究表明,尽管影响植物性状的因素复杂,但叶片性状与气候和生态之间存在非常强的经验关系。我们利用这些关系开发了重建气候和生态学的模型,这些模型已应用于地球历史上的各种环境。
这些方法完善了古气候和古生态学的重建,从而提供了比仅研究现代地球更全面的陆地生态系统和气候的理解。这种观点对于理解我们未来的地球在气候和生态系统对人为影响的反应中会发生什么至关重要。这是一种基于叶子生理学的方法,这意味着它不需要准确的分类学鉴定。
此外,DiLP 使用连续叶性状的数字测量,而不是定性和分类测量,这允许更高的可重复性,并且这些叶性状与气候具有功能关系。
