摘要

现存针叶林的一个关键特征是种子在枯木上发芽和生长的比例很高；在一些森林中，这个比例可以超过90%。这种枯木可以作为幼树的理想苗圃，导致这种类型的苗床被称为“护士原木”。目前还不清楚这种生态策略在针叶树的进化史上有多普遍。在这里，我们用经典的古植物学技术和显微镜描述了一个来自苏格兰侏罗纪的距今1.5亿年前的木片。我们在裸子植物的进化中解释了我们的新发现，并对化石护士日志，真菌和节肢动物的进化进行了文献回顾。我们将这棵原木的腐烂过程的时间轴解释为三个主要阶段：木材被白袋腐病分解；两种节肢动物，可能是甲虫和螨虫；以及小根的殖民化。这些发现证明了发生在侏罗纪森林地面上的腐烂过程的复杂性，以及白腐和节肢动物在护士原木生态策略中发挥的关键作用。白腐真菌促进了针叶树在护士原木上的萌发，这是一种与地质时间尺度上形成森林生态系统相关的保守生态策略。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
