Nitrogen availability increases in a tundra ecosystem during five years of experimental permafrost thaw
Perennially frozen soil in high latitude ecosystems (permafrost) currently stores 1330–1580
Pg of carbon (C). As these ecosystems warm, the thaw and decomposition of permafrost is …

Direct and indirect effects of native range expansion on soil microbial community structure and function
Analogous to the spread of non‐native species, shifts in native species' ranges resulting
from climate and land use change are also creating new combinations of species in many …
