Congruent patterns of functional diversity in saproxylic beetles and fungi across European beech forests

摘要: Aim: Beech forests comprise a globally unique temperate forest type in Europe. The dominance of beech these developed during the ongoing post-glacial northward re-colonization, concurrently with intensified use by humans. We investigated how two processes together climate shaped patterns of functional diversity major species groups involved wood decomposition and whether functional is determined on local or regional pool level. Location: European distribution range. Taxon: Saproxylic beetles fungi. Methods: analysed records 532,496 saproxylic 788 8,630 234 fungal based sets traits similar to both groups. tested space, landscape composition affect trait-based scales. Using structural equation modelling, we scale. Results: response fungi followed highly congruent pattern decreasing towards north, higher elevation accounted for overall geographical gradients temperature, while increasing precipitation. Structural modelling revealed that community changes operating level pool. Main conclusions: Our findings suggest organisms are mainly scale driven anthropogenic biogeographical processes. To conserve variation hotspots forests, activities have focus broad spatial climatic range sites throughout Europe, including primeval east, as started UNESCO World Heritage selection “Ancient Primeval Forests Carpathians Other Regions Europe”.
