Contrasting microbial biogeographical patterns between anthropogenic subalpine grasslands and natural alpine grasslands.

摘要: Summary The effect of plant species composition on soil microbial communities was studied at the multiregional level. We compared alpine natural grasslands dominated by Carex curvula and anthropogenic subalpine pastures Nardus stricta. We conducted paired sampling across Carpathians Alps used Illumina sequencing to reveal molecular diversity microbes. We found that bacterial fungal exhibited contrasting regional distributions distribution in each grassland is well discriminated. Beta much higher C. curvula due a marked effect. The grassland-type core microbiomes suggest C. curvula, N. stricta lesser extent, tend select cohort microbes related antibiosis/exclusion, pathogenesis endophytism. We discuss these findings light postglacial history grasslands, habitat connectivity disturbance regimes. Human-induced belt European mountains has led homogeneous large biogeographical scales. Our results confirm overarching role dominant highlight relevance history.
