Arbuscular mycorrhizal fungi community and glomalin in dry forest ecosystems, Brazil
This study aimed to evaluate the abundance and diversity of arbuscular mycorrhizal fungi (AMF) and production of soil protein related to Glomalin (PSRG) (GT- Total Glomalin; GFE - easily extractable Glomalin) in Dry Forest ecosystems in North of Minas Gerais. The soil samples were collected in areas with different stages of succession (early, middle, late and pasture) in the Dry Forest State Park in the municipality of Manga, MG. Sampling was completely random, and three simple samples were collected to form a composite sample in a total of nine composite samples by study areas. The production of AMF propagules (spores and mycelial biomass external), their diversity (total wealth and Shannon and Pielou indices) and PSRG production were stimulated in early succession areas (early stage and pasture), which were equivalent or better to areas in more advanced succession stages (intermediate and late). Such pattern may contribute to the establishment of early succession plant species, which often have high mycorrhizal dependency, and consequently advance the successional process.
