Abstract: | Species composition of arbuscular mycorrhizal fungi (AMF) was analysed in two differently managed mountain grasslands in Thuringia
(Germany). Arbuscular mycorrhizal fungi were studied in the roots of 18 dominant plant species from a total of 56 (32%). Additionally,
spores of AMF were isolated from soil samples. Arbuscular mycorrhizal fungi species composition was analysed based on 96 sequences
of the internal transcribed spacer of the nuclear ribosomal DNA, 72 originated from mycorrhizal roots, and 24 originated from
AMF spores. Phylogenetic analyses revealed a total of 19 AMF species representing all genera of the Glomeromycota except Scutellospora and Pacispora. Despite a different farming intensity, resulting in remarkable differences concerning their plant species diversity (27
against 43 plant species), the diversity of AMF was found to be similar with 11 species on the intensively farmed meadow and
ten species on the extensively farmed one. Nevertheless, species composition between both sites was clearly different. It
thus seems likely that the AMF species composition, but not necessarily the species number, is related to above ground plant
biodiversity in the system under study. |
