Póster presentado en el XV Congreso Nacional de la AEET. "El valor de la naturaleza par una sociedad global"18-21 de octubre, Plasencia, Cáceres Understanding how mycorrhizal associations will respond to changes in environmental conditions will help us to elucidate the vulnerability of plant communities to ongoing warming and drying, and the repercussions of these climate-induced changes on ecosystem functioning. However, there are still many gaps on the mechanisms underpinning shifts in mycorrhizal associations under future climatic scenarios, particularly in agroforestry ecosystems. We carried out a field manipulative experiment of rainfall exclusion and increased temperature aimed to evaluate the impact of forecasted warming and drying on mycorrhizal associations in agroforestry systems located in southwestern Spain. Additionally, we compiled detailed information on the abiotic and biotic environment with the final aim of disentangling the direct and indirect effects of climate change on this widespread mycorrhizal symbiosis. Our results suggest that climate change could induce relevant changes in mycorrhizal associations, primarily promoted by warming, which decreased the abundance of mycorrhizae but induced higher activity of nutrient exchange between the host-plant and the mycosymbiont. Temperature did not only affect this symbiosis in a direct way, but also exerted relevant indirect effects via changes in soil functioning and other root-colonizing microorganisms such as dark septate endophytes. Results from this study suggest that mycorrhizal fungi might become less prevalent in plant communities inhabiting agroforestry ecosystems under future scenarios of increasing aridity. These findings are also potentially useful to be applied in ecologically-based management strategies aimed at attenuating the potential impact of global change on mycorrhizal fungi.
