Trees exhibit different growth rates and timings of wood formation. However, the factors explaining these differences remain undetermined, making samplings and estimations of the growth dynamics a complicated task based on technical rather than statistical reasons. We collected weekly wood microcores in 159 balsam firs (Abies balsamea (L.) Mill.) from April to October 2018. We tested spatial autocorrelation, tree size, and cell production rates as explanatory variables of xylem phenology, ...

Free, in person and onlineThe stable isotopic compositions of carbon and oxygen (d13C and d18O) measured in tree rings are valuable proxies for reconstructing paleoclimate and are increasingly used as paleophysiological proxies. Applying these proxies in ecophysiology and paleoclimate can be challenging as they rely on complex process-based models and poorly constrained input data. In recent years, h...
