Efecto de la heterogeneidad espacial y estacional del suelo sobre la abundancia de esporas de hongos micorrizógenos arbusculares en el valle semiárido de Tehuacán-Cuicatlán, México

Arbuscular mycorrhizal fungi (AMF) spores are significantly more abundant beneath the canopies of Mimosa species, forming resource islands (RIs), compared to open areas (OA) in the semi-arid Tehuacán-Cuicatlán Valley. This study reveals that AMF spores are most concentrated near the trunks of Mimosa trees, with decreasing abundance toward the canopy margins and OA. Seasonal variations also play a role, as spore numbers peak during the wet season and decline through the dry season. The findings highlight the importance of Mimosa RIs as reservoirs for AMF spores, which could enhance plant survival and establishment in nutrient-poor, semi-arid environments. This research underscores the ecological significance of AM fungi in shaping plant diversity across arid and temperate ecosystems.
