Taxonomic, functional, and phylogenetic diversity of fungi in a forest-tundra ecotone in Québec
We quantified the taxonomic, functional, and phylogenetic diversity of fungi associated with dead moss tissues and conifer needles in a forest-tundra ecotone in a sub-Arctic region, Quebec, Canada. We detected 615 operational taxonomic units, in total, of fungi in 84 families with 97% sequence simil...
