Abstract
Plant species aboveground allometry can be viewed as a functional trait thatreflects the evolutionary trade-off between above- and belowground resources.In forest trees, allometry is related to productivity and resilience in differentenvironments, and it is tightly connected with a compromise between efficiency-safety and competitive ability. A better understanding on how this traitvaries within and across species is critical to determine the potential of a species/population to perform along environmental gradients. We followed a hierarchicalframework to assess tree height-diameter allometry variation withinand across four common European Pinus species. Tree height-diameter allometryvariation was a function of solely genetic components &-approximated byeither population effects or clinal geographic responses of the population&;39;s siteof origin&- and differential genetic plastic responses &-approximated by the interactionbetween populations and two climatic variables of the growing sites(temperature and precipitation)&-. Our results suggest that, at the species level,climate of the growing sites set the tree height-diameter allometry of xeric andmesic species (Pinus halepensis, P. pinaster and P. nigra) apart from the borealspecies (P. sylvestris), suggesting a weak signal of their phylogenies in the treeheight-diameter allometry variation. Moreover, accounting for interpopulationvariability within species for the four pine species aided to: (1) detect geneticdifferences among populations in allometry variation, which in P. nigra andP. pinaster were linked to gene pools &-genetic diversity measurements&-# (2)reveal the presence of differential genetic variation in plastic responses alongtwo climatic gradients in tree allometry variation
