Aboveground-belowground biodiversity linkages in dairy sheep systems with different grazing regimes.

摘要: Understanding linkages between plant diversity aboveground and that of microorganisms belowground constitutes an important challenge for the sustainability of permanent pastures and the knowledge of the ecosystem services that they provide. This study was carried out to test the effect of two different grazing regimes (called regenerative grazing and free grazing) and ungrazed treatment at pastures' biodiversity level. Data collected after a one year grazing regime were used to search for the linkages between plant and microbial communities. According to the results, plant richness and belowground biodiversity showed a tendency towards lower values under ungrazed conditions, and both indexes showed a tendency to higher diversity in a regenerative grazing regime. Relating to the interactions between aboveground plant structural and belowground soil functional composition, bare ground had a …
