Microbial ecology in a future climate: effects of temperature and moisture on microbial communities of two boreal fens.

摘要: Impacts of warming with open-top chambers on microbial communities in wet conditions and resulting from moderate water-level drawdown (WLD) were studied across 0–50 cm depth northern southern boreal sedge fens. Warming alone decreased biomass especially the fen. Impact PLFA fungal ITS composition was more obvious fen linked to moisture regime sample depth. Fungal-specific increased surface peat drier layers below 10 after warming. OTUs representing Tomentella Lactarius observed Mortierella The ectomycorrhizal fungi responded only WLD. Interestingly, together WLD archaeal 16S rRNA copy numbers general, Expectedly, many results indicated that response may be regime. Results community Arctic soils would sensitive environmental changes. future climate change clearly vary even within a habitat type, exemplified here by
