The ectomycorrhizal community of an oak forest has been monitored monthly throughout fifteen months. Eight enzymatic activities secreted by the ectomycorrhizal root tips and involved in the mobilization of nutrients from soil organic matter have been measured using microplate assays, resulting in potential activity patterns of individual fungal species. Both the species structure of the community and the specific activity level of each individual species changed with the season and soil horizon. This versatility may be an adaptative response of the ectomycorrhizal fungal community to a highly variable environment. The results also suggest that some ectomycorrhizal fungi behave as occasional saprobes and contribute to the decomposition of soil organic matter and nutrient cycling together with true saprotrophic fungi.Read less <
