- Soil fungal composition and diversity in pure and mixed forests of Quercus suber and Pinus pineaPublication . Barcik, Pedro; Correia, Alexandra Cristina Pires; Talhinhas, Pedro Manuel VieiraSoil fungi play a critical role in forests, especially in the Mediterranean, a region characterized by nutrient-poor soils and a high susceptibility to desertification. The Mediterranean tree species cork oak (Quercus suber L.) and stone pine (Pinus pinea L.) have high economic and ecological importance but face many threats, which are prone to increase with climate change. Adaptative management alternatives are required and mixing the two species is one possibility since they share the same ecological niche. Forest mixtures are known to increase forest resilience against disturbances, but the effect on soil fungi remains understudied in this region. In that sense, a possible change from the traditional management of these forests requires more information to support stakeholders in the decision-making process regarding mixed forests. This study aims to characterize the composition of fungi associated with Q. suber and P. pinea and investigate the effects of their mixture on fungal diversity. It was carried out in a network of triplets in six managed estates located in Central-South Portugal. To identify the fungi, metabarcoding targeting the rDNA-ITS region of the soil DNA was chosen due to its high efficiency. The results show that all plots presented high abundances of Ascomycota, mainly due to Penicillium, and in most locations the ectomycorrhizal community was dominated by Russulaceae associated with Q. suber, highlighting the importance of cork oak in shaping the soil mycobiome. Furthermore, mixed stands tended to be more diverse than pure stands with a more even fungal community distribution, while its soil fungal community lay in between both pure stands, whose communities were highly dissimilar. In conclusion, these results support the mixture of Q. suber and P. pinea as a viable management alternative for the adaptation of Mediterranean forests and the protection of their soil fungi in the context of a changing climate.
