How beech ecophysiology shapes temperate forest gross primary productivity – Part 1: A wavelet-based framework for extracting seasonal dynamics

Long-term eddy covariance (EC) records provide unique opportunities to investigate how seasonal carbon dynamics shape interannual and decadal trends in forest carbon uptake. Yet extracting reproducible phenological and structural information from noisy, non-stationary gross prima...

How beech ecophysiology shapes temperate forest gross primary productivity – Part 2: Identifying critical timeframes across phenological stages

Seasonal processes fundamentally shape forest carbon uptake, yet their timing and sensitivity remain poorly resolved. Using a 24-year eddy-covariance record from a maturing beech forest (FR-Hes), we developed three annual ecophysiological indicators (IRise, IPeak and IDrop) of gr...
