dcterms.abstractThe presence of shrubs in semiarid rangelands has been associated with changes in the spatial distribution of soil resources. However, the relationships between woody species and arbuscular mycorrhizal fungi (AMF) remain unclear. This study investigated the influence of shrub cover on AMF communities and their associations with soil quality indicators. In spring 2017, five paddocks were selected in a semiarid Monte rangeland of Argentina. Two 10-m transects were established in each paddock: one in a shrub-dominated patch (Sh) and one in a shrub-free patch (WSh). Within each transect, sampling sites were categorized as grass-covered (Sh-G and WSh-G), bare ground-litter (Sh-BL and WSh-BL), or under shrubs (Sh-S). Composite soil samples (5 cores per site, 0–10 cm in depth) were collected within each site for AMF spore extraction and identification. Entrophosporaceae abun-dance was higher in Sh-BL than Sh-G and Sh-S sites. Glomeraceae abundance was lower in Sh-G and Sh-BL than in the same sites in WSh transects. Ruderal/rhizophilic AMF presented higher abundance in WSh-BL than in Sh-S and Sh-BL sites, while stress tolerant/ancestral AMF were more abundant in Sh-G than in WSh-G sites. Soil organic matter, its labile fraction, and cellulase activity correlated positively with the abundance of Ambis-poraceae and Pacisporaceae, but negatively with Entrophosporaceae. These results indicate that shrub species tend to favor the presence of stress tolerant/ancestral AMF over more generalist or ruderal/rhizophilic types commonly found in the soil nearby. These effects may be driven by increased organic fractions and microbial activity associated with the soil carbon cycle.en
