How does tree phenology respond to a warmer climate?

In the latest paper published in Agricultural and Forest Meteorology together with our collaborators from Bordeaux we consider the effect of warming on the phenology of European beech.

September, October, November relationships with Leaf senescence
The interactive relationship between leaf senescence and the mean temperature in September, October and November (Tm SON) for (a) the trial and (b) for the provenance.

Using ΔTrait Species Distribution Modelling of a large dataset from provenance trials, we established that not only earlier spring phenology but also delayed leaf senescence in northern populations allowed them to exploit warmer summer temperatures.

Beech is one of those forest trees that utilises a combination of temperature and day-length cues to prompt advancement of its annual growth cycle, meaning the climate warming and associated northerly range shifts have potentially complex outcomes for its phenology.
