Strong paleoclimatic legacies in current plant functional diversity patterns across Europe.

摘要: Numerous studies indicate that environmental changes during the late Quaternary have elicited long-term disequilibria between species diversity and environment. Despite its importance for ecosystem functioning, of historical conditions as determinants FD (functional diversity) remains largely unstudied. We quantified geographic distributions plant (richness dispersion) across Europe using distribution functional trait information 2702 species. then compared contemporary factors to determine relevance past predictors current in Europe. For this, we strength relationships with temperature precipitation stability since LGM (Last Glacial Maximum), accessibility refugia, (climate, productivity, soil, topography, land use). Functional richness dispersion exhibited patterns strong associations history region. The effect size refugia climate was comparable predictors. Both increased refugia. richness' pattern primarily associated growing degree-days, use heterogeneity, soil types, absolute minimum winter temperature. dispersion's degree-days high explained variance model support are consistent idea variability supplements shaping at continental scales. Given future change may elicit not just short-term shifts but also disequilibria.
