Tracing growing degree‐day changes in the cuticle morphology of Betula nana leaves: a new micro‐phenological palaeo‐proxy
Abstract Changing growing‐season properties in the northern latitudes are among the most obvious consequences of ongoing global change. Available techniques including satellite monitoring and phenological observations enable the detection of changes over the last few decades to centuries, but the fu...

Abstract Changing growing‐season properties in the northern latitudes are among the most obvious consequences of ongoing global change.
