N2 - In forest ecosystems, ectomycorrhizal symbiosis is able to produce a large range of extracellular and cell wall-bound enzymes which hydrolyze compounds contained in soil organic matter. Enzymatic activity profiles of individual ectomycorrhiza have value of functional traits to characterize the diversity of ectomycorrhizal (ECM) communities. Fagus mexicana is an endemic and only species that has restricted distribution to cloud forest of Sierra Madre Oriental in México and there are few works focused to the relationship between this forest species and ectomycorrhizal, which enhance its growth and development. This work analyzes the enzyme functional diversity of ectomycorrhizal fungi associated to F. mexicana trees of different ages. In this study, the ECM species: Cantharellus cibarius Fr., Laccaria amethystina Cook, Lactarius subdulcis (Pers.) gray and Xathoconium separans (Peck) Halling & Both, were founded near these trees and the influence of the niche on the mean catabolic activity of ectomycorrhizal community, varied according to the dominant substrate; where L. amethystina and X. separans presented the highest β-glucosidase and acid phosphatase activities in F. mexicana tips. The enzymatic profiles demonstrated a functional plasticity of the ectomycorrhizal species associated to the age of trees tested and also could be a trait of their capability of adaptation to the cloud forest ecosystem.
