The Physio-Demo-Genetics model (denoted PDG) is an individual-based, spatially explicit mechanistic simulation model, coupling (1) a physiological module simulating individual tree responses to the environment (the CASTANEA model, Dufrêne et al. 2005); (2) a demographic module simulating tree survival, reproduction and pollen and seed dispersal; and (3) a quantitative genetics module controlling the heritability of key life history traits (implemented in CAPSIS Genetics library, Seinave & Pichot 2004). PDG model was used to investigate the plastic and genetic components of the variations of the timing of budburst along an altitudinal gradient of Fagus sylvatica (the European beech), in the reference publication of PDG (Oddou-Muratorio & Davi 2014).
