Expansion of shrubs could result in local loss of soil bacterial richness in Western Greenland
ABSTRACT Climate warming in Greenland is facilitating the expansion of shrubs across wide areas of tundra. Given the close association between plants and soil microorganisms and the important role of soil bacteria in ecosystem functioning, it is of utmost importance to characterize microbial communi...
