摘要

雷击每年杀死数亿棵树,但它们在塑造树木生命历史和多样性方面的作用在很大程度上是未知的。在这里,我们使用来自一个独特的闪电定位系统的数据来显示一些单独的树木从被闪电击中中获益,这与我们的直觉相反。93棵直接被闪电击中的树木中有56%被闪电击中,幸存者中平均有41%的树冠枯死。然而,在这些被击中的树木中,10次直接撞击对油雀鸟树木的损害可以忽略不计,但杀死了78%的藤本植物和2.1 Mg的竞争树种生物量。其他九种长寿的树木在闪电中幸存下来,也有类似的好处。平均而言,一棵直径60厘米的油桐树在其一生中至少会被闪电击中五次,从而反复获得这些好处。我们估计,在闪电中生存的能力将终生繁殖力提高了14倍,这主要是因为藤本植物和邻近树木的竞争减少了。此外,相对于同直径、异速生长的树木,油松树不同寻常的高度和较宽的树冠使直接命中的概率增加了49% ~ 68%。这些模式表明闪电在树木竞争、生活史策略和物种共存中起着未被充分认识的作用。

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.
