Climatically controlled allocation to reproduction is a key mechanism by which climate influencestree growth and may explain lagged correlations between climate and growth. We used continent-wide datasets of tree-ring chronologies and annual reproductive effort inFagus sylvaticafrom1901 to 2015 to characterise relationships between climate, reproduction and growth. Resultshighlight that variable allocation to reproduction is a key factor for growth in this species, andthat high reproductive effort (‘mast years’) is associated with stem growth reduction. Additionally,high reproductive effort is associated with previous summer temperature, creating lagged climateeffects on growth. Consequently, understanding growth variability in forest ecosystems requiresthe incorporation of reproduction, which can be highly variable. Our results suggest that futureresponse of growth dynamics to climate change in this species will be strongly influenced by theresponse of reproduction.
