丛枝菌根森林中的外生菌根树岛:真菌接种体的热点地区对历史上优势树种的育苗至关重要
北美东北部的落叶林由外生菌根(EM)树和丛生菌根(AM)树混合组成。然而,由于土地利用的遗留问题和其他因素,EM 树减少,AM 树占优势的情况同时增加,这可能会限制森林生态系统功能的发挥。我们研究了分散的 EM 树斑块和来自当地 EM 树占主导地位的森林的土壤接种物如何影响以 AM 树为主的次生林中的 EM 真菌定植、EM Tsuga canadensis、Pinus strobus 和 Quercus spp.树苗的存活和生长。在纽约的三片次生林中,幼苗被种植在优势AM槭树和零星的EM桦树旁。一部分树苗还接受了来自当地 EM 优势森林的土壤接种物。我们对幼苗的存活率和高度生长进行了为期两年的监测,然后测量了幼苗嫩枝的生物量,评估了EM定植情况,并从幼苗根部鉴定了EM真菌。与种植在AM Acer树附近的幼苗相比,种植在EM Betula树附近的所有属的幼苗的EM定植率和真菌丰富度都更高。接种 EM 森林土壤只增加了 AM Acer 附近幼苗的 EM 定殖率和真菌丰富度,这在缺乏本地 EM 真菌的地区非常有效。幼苗根部的 EM 真菌总多样性在 EM Betula 附近最高,其中包括许多通常与成熟树木相关的类群。相比之下,AM Acer 附近的 EM 真菌群落稀少,主要由相对较少的孢子库真菌类群主导。虽然不同处理的幼苗存活率并无差异,但土壤接种和靠近 EM Betula 可增加松树和铁杉第二年的高度生长,而单独的土壤接种则可显著提高柞树幼苗的枝量。综述。农业用地的遗留问题造成了以AM树为主的广阔次生林。在这些森林中,由于缺乏EM真菌,在现有的EM树斑块外建立EM树幼苗可能会受到阻碍,但来自EM树为主的森林的本地土壤接种物可将本地EM真菌重新引入缺乏已建立的EM树的次生林中。

期刊介绍: Journal of Ecology publishes original research papers on all aspects of the ecology of plants (including algae), in both aquatic and terrestrial ecosystems. We do not publish papers concerned solely with cultivated plants and agricultural ecosystems. Studies of plant communities, populations or individual species are accepted, as well as studies of the interactions between plants and animals, fungi or bacteria, providing they focus on the ecology of the plants. We aim to bring important work using any ecological approach (including molecular techniques) to a wide international audience and therefore only publish papers with strong and ecological messages that advance our understanding of ecological principles.
