“…We agree with the suggestions that after removal of invasive plants, the plots should be restored with native plant species at levels of diversity similar to that of the surrounding vegetation in order to promote AMF proliferation and diversity (Zubek 2012;Tanner and Gange 2013). It is also worth noting that manual and mechanical removal of invaders may intensify the disturbance of the microbial community by further disrupting and depleting the AMF network (Tanner and Gange 2013;Lankau et al 2014).…”

We studied the effects of invasions by three plant species: Reynoutria japonica, Rudbeckia laciniata, and Solidago gigantea, on arbuscular mycorrhizal fungi (AMF) communities in habitats located within and outside river valleys. Arbuscular mycorrhizal colonization, AMF abundance and species richness in soils were assessed in adjacent plots with invaders and native vegetation. We also quantified the performance (expressed as shoot mass, chlorophyll fluorescence, and the concentration of elements in shoots) of two common, mycorrhizal native plants, Plantago lanceolata and Trifolium repens, grown in these soils. The invasions of R. japonica, R. laciniata, and S. gigantea influenced AMF communities compared to native vegetation, but the changes depended on the mycorrhizal status of invaders. The effects of non-mycorrhizal R. japonica were the most pronounced. Its invasion reduced AMF abundance and species richness. In the plots of both mycorrhizal plants, R. laciniata and S. gigantea, we observed decreased AMF species richness in comparison to native vegetation. The AMF community alterations could be due to (i) depletion of organic C inputs to AMF in the case of R. japonica, (ii) plant secondary metabolites that directly inhibit or selectively stimulate AMF species, or (iii) changes in soil physicochemical properties induced by invasions. The effect of invasion on AMF abundance and species richness did not generally differ between valley and outside-valley habitats. The invasions affected photosynthetic performance and the concentrations of elements in the shoots of P. lanceolata or T. repens. However, the directions and magnitude of their response depended on both species identity and the mycorrhizal status of invaders.

“…However, correlations between the effect of Alliaria and population age were not as apparent as in the 2009 study. While links between mycorrhizal community structure and native plant performance may be unclear, alterations in mycorrhizal community structure induced by the presence of Alliaria persisted for at least six years after its removal from a forested habitat (Lankau et al 2014).…”

“…The connection between landuse legacies and AMF abundance has been a subject of great interest to the scientific community. Legacy effects of land-use changes have been considered among the most influential disturbances affecting diversity, community structure, and ecosystem functioning and services of microbial communities [7,8]. Legacy effects occur when the presence of previous vegetation or land use alters soil properties or organism species pools in ways that persist even if the previous vegetation is changed due to succession, deliberate conversion, or restoration [8][9][10][11][12].…”

For example, land-use changes have been found to alter the soil characteristics and aboveground species dynamics [13][14][15][16] and consequently influence microbial community structure and function [16][17][18][19][20].…”

Arbuscular mycorrhizal fungi (AMF) can be important mutualists to plant hosts in acquiring soil nutrients. Past work has not explored whether previous land-cover history influences current AMF abundance in croplands and whether different land-cover histories in grazed but not cultivated areas influence AMF. This study was conducted to assess the effects of land-cover history in and near Serengeti National Park on AMF abundance in areas with three different land uses. The results showed that land-cover history influenced a number of soil physicochemical properties following conversion of grassland to cropland or woodland to cropland during the past 27 years. Different original land cover generally did not significantly influence current AMF abundance in croplands or livestock-grazed soils. However, livestock-grazed current grasslands that were formerly woodlands had lower AMF abundance than sites that had been grasslands since 1984. These results suggest that lower AMF abundance in livestock-grazed and cropland areas as compared to protected wildlife-grazed areas may reflect reduced total carbon inputs and higher disturbance and are not strongly influenced by the legacy of previous land cover. Given that recent studies have detected legacy effects on AMF, such effects may reflect more the impact on the taxonomic composition of AMF rather than their total abundance.
