Contrasting Soil Bacterial and Fungal Communities between the Swamp and Upland in the Boreal Forest and their Biogeographic Distribution Patterns

Abstract

Boreal forest encompasses approximately 30% of the terrestrial carbon (C) storage, representing an important hotspot of C transformations mediated by soil microbial communities in the changing environment. However, our understanding of the microbial community characteristics and the core components of soil microbiome in different succession scenarios of boreal forest is still limited. Here, we compared the diversity, activities and community composition of both bacteria and fungi between upland and swamp boreal forest soils. The microbial diversity and activity were remarkably lower in swamp than upland soils. The bacterial and fungal community compositions were significantly different betwe..
