摘要

我们在全球范围内评估了道路干扰对生态系统中主要菌根类型的影响,以及这种机制如何可能导致持久的植物群落变化。我们使用了全球 11 个山区 894 个地块的山区道路沿线植物群落协调调查数据库,并结合现有的菌根植物关联数据库,以估算自然环境和干扰环境中菌根类型的相对丰度。我们的研究结果表明,路边干扰会促进与丛枝菌根(AM)真菌相关的植物的覆盖。在寒冷的山区环境和植物群落以外生菌根(EcM)或麦角菌根(ErM)结合为主的山区,这种效应尤为明显。此外,非本地植物物种(我们证实它们大多是 AM 植物)在以 AM 结合为主的环境中更容易成功。这些生物地理模式表明,菌根类型的变化可能是人为干扰对全球山区生态系统影响的一个关键因素。事实上,路边培育了以AM为主的系统,在这种系统中,AM真菌可能会帮助与AM相关的植物物种,同时有可能降低生物对入侵非本地物种的抵抗力,而这通常也与AM网络有关。山区生态系统的恢复工作必须应对路边干扰引起的生态管理和环境管理植物群落基本构成的变化。

Roadside disturbance promotes plant communities with arbuscular mycorrhizal associations in mountain regions worldwide

Roadside disturbance promotes plant communities with arbuscular mycorrhizal associations in mountain regions worldwide

We assessed the impact of road disturbances on the dominant mycorrhizal types in ecosystems at the global level and how this mechanism can potentially lead to lasting plant community changes. We used a database of coordinated plant community surveys following mountain roads from 894 plots in 11 mountain regions across the globe in combination with an existing database of mycorrhizal–plant associations in order to approximate the relative abundance of mycorrhizal types in natural and disturbed environments. Our findings show that roadside disturbance promotes the cover of plants associated with arbuscular mycorrhizal (AM) fungi. This effect is especially strong in colder mountain environments and in mountain regions where plant communities are dominated by ectomycorrhizal (EcM) or ericoid-mycorrhizal (ErM) associations. Furthermore, non-native plant species, which we confirmed to be mostly AM plants, are more successful in environments dominated by AM associations. These biogeographical patterns suggest that changes in mycorrhizal types could be a crucial factor in the worldwide impact of anthropogenic disturbances on mountain ecosystems. Indeed, roadsides foster AM-dominated systems, where AM-fungi might aid AM-associated plant species while potentially reducing the biotic resistance against invasive non-native species, often also associated with AM networks. Restoration efforts in mountain ecosystems will have to contend with changes in the fundamental make-up of EcM- and ErM plant communities induced by roadside disturbance.

期刊介绍: ECOGRAPHY publishes exciting, novel, and important articles that significantly advance understanding of ecological or biodiversity patterns in space or time. Papers focusing on conservation or restoration are welcomed, provided they are anchored in ecological theory and convey a general message that goes beyond a single case study. We encourage papers that seek advancing the field through the development and testing of theory or methodology, or by proposing new tools for analysis or interpretation of ecological phenomena. Manuscripts are expected to address general principles in ecology, though they may do so using a specific model system if they adequately frame the problem relative to a generalized ecological question or problem. Purely descriptive papers are considered only if breaking new ground and/or describing patterns seldom explored. Studies focused on a single species or single location are generally discouraged unless they make a significant contribution to advancing general theory or understanding of biodiversity patterns and processes. Manuscripts merely confirming or marginally extending results of previous work are unlikely to be considered in Ecography. Papers are judged by virtue of their originality, appeal to general interest, and their contribution to new developments in studies of spatial and temporal ecological patterns. There are no biases with regard to taxon, biome, or biogeographical area.
