Root traits along a subarctic tundra elevational gradient

While root trait research has received increasing attention over the past
two decades, the relationship between root traits and environmental
factors remains elusive. At the same time, knowledge about these
relationships is necessary if we are to understand plant community
responses to environmental change. Here, we assessed the relationships
between elevation (i.e., temperature) and fine root traits of plant
species and communities. We focused on the sub-arctic tundra where plant
communities are expected to experience extreme environmental change by the
end of the century.
