Abstract

In temperate mixed forests, dominant ectomycorrhizal (EM) tree species usually coexist with diverse arbuscular mycorrhizal (AM) understorey tree species. Here, we investigated the spatial associations between AM and EM trees in two > 20 ha temperate forest mega-plots to better understand the observed ‘EM-dominant versus AM-diverse’ coexistence. Overall, we found that positive spatial associations (e.g., facilitation) were mostly related to EM trees, while negative spatial associations (e.g., inhibition) were mainly related to AM trees. Because adult EM trees tended to facilitate surrounding AM and EM saplings and other EM adults in these two forests, facilitation hotspots that stabilize AM-EM tree coexistence should be centred around EM tree species rather than around AM tree species. Together, we propose a novel EM-stabilization mechanism, which emphasises how, despite some species-specific variation, EM tree species foster ‘EM-dominant versus AM-diverse’ coexistence in temperate mixed forests by facilitating other trees.

菌根类型调节温带森林中树木的空间组合:外生菌根树木可能有利于物种共存
在温带混交林中,优势的外生菌根(EM)树种通常与多样性的丛生菌根(AM)林下树种共存。在这里,我们调查了两块面积大于 20 公顷的温带森林巨型地块中 AM 树和 EM 树之间的空间关联,以更好地理解观察到的 "EM 优势树种与 AM 多样树种 "共存现象。总体而言,我们发现积极的空间关联(如促进)主要与EM树有关,而消极的空间关联(如抑制)主要与AM树有关。由于在这两片森林中,EM成树倾向于促进周围的AM和EM树苗及其他EM成树,因此稳定AM-EM树共存的促进热点应集中在EM树种周围,而不是AM树种周围。综上所述,我们提出了一种新的EM稳定机制,它强调了尽管存在一些物种特异性差异,但EM树种如何通过促进其他树种来促进温带混交林中 "EM主导型与AM多样性 "的共存。

期刊介绍: Ecology Letters serves as a platform for the rapid publication of innovative research in ecology. It considers manuscripts across all taxa, biomes, and geographic regions, prioritizing papers that investigate clearly stated hypotheses. The journal publishes concise papers of high originality and general interest, contributing to new developments in ecology. Purely descriptive papers and those that only confirm or extend previous results are discouraged.
