Climate and air pollution impacts on habitat suitability of Austrian forest ecosystems.

摘要: Climate change and excess deposition of airborne nitrogen (N) are among the main stressors to floristic biodiversity. One particular concern is deterioration valuable habitats such as those protected under European Habitat Directive. In future, climate-driven shifts (and losses) in species potential distribution, but also N driven nutrient enrichment may threaten these habitats. We applied a dynamic geochemical soil model (VSD+) together with novel niche-based plant response (PROPS) 5 forest habitat types (18 sites) EU Directive Austria. assessed how future climate might affect suitability, defined capacity site host its typical species. Our evaluation indicates that will be driver decrease suitability The expected increase occurrence thermophilic while decreasing cold-tolerant addition direct impacts, scenarios caused an probability oligotrophic due higher immobilisation woody biomass leading depletion. As consequence, did offset eutrophication from deposition, even when no further reduction emissions was assumed. results show have positive side-effects multiple drivers considered.
