| Given the jeopardy that biodiversity is currently facing, robust assessments on future shift of the geographical range of species are of utmost importance. Species Distribution Models (SDMs) are widely used to estimate current and future potential distributions of many organisms. However, a frequent lack of pertinent data on variables other than climate in SDMs, despite these being known to influence range dynamics, has often precluded an integrative approach to account for the effects of species-specific functional traits on the geographical ranges of species. Here, we use an ongoing database (GEOFEN) with information on geographical range of trees in Europe, climate, soils, and several phenotypic traits to make clear the effects of abiotic and biotic drivers on range size and range filling (i.e., the proportion of the potential range delimited by niche modelling that is actually occupied; [Svenning & Skov 2004, Ecology Letters 7: 565-573]). First, we use several modelling techniques to map the climatic niche of 55 tree species in Europe. Second, we apply a common classification of tree soil preferences to fine-tune the modelled distribution of species by accounting for soil water retention capacity and pH effects. Third, we test whether ecophysiological traits (growth rate and tolerances to drought and shade) bear upon range size and range filling of European tree species. Disentangling the role of ecophysiological traits in the geographical range of tree species through this approach will enhance the understanding and prediction of range shifts in response to climate change. | |
