Zusammenfassung
Mountain pastures in the Basque Country are a consequence of permanent extensive grazing practice since the Neolithic. The current abandonment of grazing can cause significant changes in these agroecosystems, both at aboveground and belowground levels. Our main objective was to study the relationships between plant diversity and soil microbial diversity in mountain pastures with and without grazing, by studying twelve grazed versus non-grazed areas (simulated by exclusions), in the Gorbeia Natural Park. In all these areas, the number of plant species was quantified (by throwing squares at random) and the floristic diversity estimated, as well as the diversity of soil microorganisms (by next generation sequencing of 16S rRNA and fungal ITS amplicons). A positive correlation between diversity of plant and fungal communities was found only in grazed areas. In terms of composition, taxa with greater abundance and positive associations between different communities’ taxa differed primarily according to the type of parent material (calcareous or siliceous). Understanding these links would be an important step forward in our knowledge of many of the ecosystem services that provide permanent pastures.
