“…Soil properties differed greatly among the LTO sites and less between land use intensities within sites, and generally the same was true for microbial communities in this study as well as in Thomson et al (2015). The strongest consistent differ-ences in soil properties were found in Berchidda.…”

“…The strongest consistent differ-ences in soil properties were found in Berchidda. In consequence, Thomson et al (2015) also found the strongest differences in microbial communities out of all sites between Berchidda H and L, and, interestingly, also the lowest micro-bial diversity. As we did not find the same in the present study, the soil factors differing in Berchidda seemed to be of less importance for AMF than for other microbial communities.…”

“…S1). Although this sequencing depth could not assess the full extent of AMF diversity, previous studies showed that this depth of analysis is sufficient to describe differences in microbial community composition, even for taxa having high species diversity (Fierer et al 2013;Thomson et al 2015). Differences in AMF community com-position also were analyzed separately for each LTO, to eval-uate specifically the impact of the level of land use intensity.…”

“…Therefore, the same soil samples and DNA extracts from long-term observatories (LTOs) used here also were used to address the diversity of other microorganisms (Thomson et al 2015), which is Bacteria, Archaea, and Fungi in general. On a larger scale, a transect of 54 sites across Europe was analyzed in that project (which included treatments from the four LTOs analyzed here) to analyze broad patterns of AMF distribution .…”

Arbuscular mycorrhizal fungal (AMF) communi-ties have been demonstrated to respond to a variety of biotic and abiotic factors, including various aspects of land manage-ment. Numerous studies have specifically addressed the im-pact of land use on AMF communities, but usually have been confined to one or a few sites. In this study, soil AMF assem-blages were described in four different long-term observato-ries (LTOs) across Europe, each of which included a site-specific high-intensity and a low-intensity land use. AMF communities were characterized on the basis of 454 sequenc-ing of the internal transcribed spacer 2 (ITS2) rDNA region. The primary goals of this study were (i) to determine the main Mycorrhiza factors that shape AMF communities in differentially man-aged sites in Europe and (ii) to identify individual AMF taxa or combinations of taxa suitable for use as biomarkers of land use intensification. AMF communities were distinct among LTOs, and we detected significant effects of management type and soil properties within the sites, but not across all sites. Similarly, indicator species were identified for specific LTOs and land use types but not universally for high-or low-intensity land uses. Different subsets of soil properties, includ-ing several chemical and physical variables, were found to be able to explain an important fraction of AMF community var-iation alone or together with other examined factors in most sites. The important factors were different from those for other microorganisms studied in the same sites, highlighting partic-ularities of AMF biology.

Abstract. Invasion by non-native plants may fundamentally restructure the soil fungal community. The invasive plant, Alliaria petiolata, produces secondary compounds suppressive to mycorrhizal fungi and may therefore be expected to have generally negative effects on other components of the fungal community. Here, we compared fungal biomass, diversity, community composition, and the relative abundance of fungal trophic guilds, along with edaphic properties of soils collected from uninvaded and invaded plots across six temperate forests. Invaded plots were differentiated from uninvaded plots by lower variation in fungal community composition (beta diversity) and soil properties, higher fungal richness and community evenness (alpha diversity), and a suite of novel saprotrophic and pathotrophic fungi that were consistently present across the invaded landscape and absent from uninvaded forest patches. Invaded plots also had lower ectomycorrhizal but higher saprotrophic and pathotrophic relative abundance, despite there being no difference in fungal biomass between invasion statuses. We hypothesize that shifts in the fungal community with invasion may directly impact plant disease response, soil nutrient cycling processes, and plant performance of the invasive and native plant communities.
