| 英文摘要 | The turnover of ectomycorrhizal (EM) fungal biomass represents an important litter input into forest biogeochemical cycles. Cenococcum geophilum is a nearly ubiquitous and often abundant EM fungus, making the turnover dynamics of this species relevant and important across forest ecosystems. To better understand the turnover dynamics of C geophilum ectomycorrhizas we examined their persistence using minirhizotron imaging and vitality status using a fluorescein diacetate (FDA) stain and contrasted these results with ectomycorrhizas of other EM fungi. Ectomycorrhizas formed by C. geophilum persisted 4-10 times longer and exhibited contrasting seasonal patterns of vitality compared to ectomycorrhizas of other EM fungi. Together, this suggests that litter resulting from the death of C geophilum ectomycorrhizas is relatively recalcitrant to decay and may disproportionately influence forest biogeochemical cycles by retarding the rate at which carbon and nutrients are cycled.
