Details
The study area is the Western Swiss Alps of Canton de Vaud, Switzerland.
Five topo-climatic explanatory variables to calibrate the SDMs: growing degree days (with a 0 degrees Celsius threshold); moisture index over the growing season (average values for June to August in mm day-1); slope (in degrees); topographic position (an integrated and unitless measure of topographic exposure; Zimmermann et al., 2007); and the annual sum of radiation (in kJ m-2 year-1). The spatial resolution of the predictor is 25 m x 25 m so that the models could capture most of the small-scale variations of the climatic factors in the mountainous areas.
Two modelling techniques were used to produce the SDMs: generalized linear models (GLM; McCullagh & Nelder, 1989; R library 'glm') and generalized boosted models (GBM; Friedman, 2001; R library 'gbm'). The SDMs correpond to 20 species: Agrostis_capillaris, Leontodon_hispidus_sl, Dactylis_glomerata, Trifolium_repens_sstr, Geranium_sylvaticum, Ranunculus_acris_sl, Prunella_vulgaris, Veronica_chamaedrys, Taraxacum_officinale_aggr, Plantago_lanceolata, Potentilla_erecta, Carex_sempervirens, Soldanella_alpina, Cynosurus_cristatus, Campanula_scheuchzeri, Festuca_pratensis_sl, Daucus_carota, Pritzelago_alpina_sstr, Bromus_erectus_sstr and Saxifraga_oppositifolia.
