Multiscale patterns of rarity in fungi, inferred from fruiting records

摘要: AIM: It is unknown whether fungi show similar trends to other organisms in their macroecological patterns of abundance and spatial distribution. Here, we investigated fungal abundance–occupancy relationships determine that are common at a local scale tend be more widely distributed. LOCATION: UK Switzerland. TIME PERIOD: 1950–2014. MAJOR TAXA STUDIED: Fungi. METHODS: We used data set fruiting records 2,319 species the UK, accumulated over 65 years, one from Switzerland 319 species, spanning 32 years. Using number occurrence as proxies for abundance, each case examined form rank distributions compared these with national databases same time. plotted regional occupancy calculated multiscale indices rarity all species. RESULTS: There was remarkable congruence found Regional assemblages characterized by many rare whereas few (fitting lognormal distribution). However, scales, best fitted power law, suggesting habitat availability or dispersal processes might play important roles. Fungi high densely distributed nationally, but unlike organisms, locally may also wider scale. MAIN CONCLUSIONS: Fungal can infer distributions. Abundances determined position assemblage overall geographical range ability environmental filtering. advocate use approaches future sampling programmes, provide reliable information conservation policy decisions biogeography.
