摘要: Bolivia is one of the most biologically diverse countries on planet. Between Andes and Amazon drainage basin spans Yungas, a vast forested region shown to be extremely species rich in macro-organisms. However, it remains unclear whether this high diversity also reflected microbial diversity. Here we assess genetic, taxonomic functional root-associated fungi surrounding Cinchona calisaya trees, typical element intermediate altitudes Bolivian Yungas. We determine relative effects edaphic properties, climate, geography regulating fungal community assembly. show that α-diversity for these communities was similar temperate arid ecosystems, averaging 90.1 operational units (OTUs) per sample, with reads predominantly assigned Ascomycota phylum saprotrophic lifestyle. s-diversity calculated as distance-decay rate, contrast α-diversity, exceptionally rate -0.407. Soil properties (pH P) principally regulated assembly an analogous manner environments, pH phosphorus explaining 7.8 % 7.2 variation respectively. Surprisingly, altitude does not influence formation, there limited evidence climate (precipitation temperature) play role. Our results suggest sampling should performed over wide geographical environmental range order capture full subtropical regions. This study sheds further light distribution world's "hidden biodiversity".
