Influence of Tree Vegetation on Soil Microbial Communities in Temperate Forests and Their Potential as a Proactive Indicator of Vegetation Shift Due to Climate Change

Abstract

Unexpected vegetation shift is a serious problem caused by climate change, resulting in considerable damage to local communities. It is necessary to be continuously monitored, and the soil microbial community is expected to reflect the pressure on forest ecosystems due to climate change. We investigated soil bacterial and fungal communities in Odaesan at a four-year interval through eDNA meta-barcoding and analyzed the compositional and functional differences between forest types (Mongolian oak (Quercus mongolica) forest with and without Manchurian firs (Abies holophylla)) and sampling years. As a result, denitrifiers predominated in the presence of Manchurian firs, but there was no difference in the influence of climate change by forest type. Although tree vegetation remained stable, the microbial communities significantly changed over four years. This result demonstrates that climate change significantly shifts the microbial communities, even if not enough to trigger a vegetation shift, thus a microbial indicator can be developed to assess the press disturbance accumulated on the forest ecosystem. Through this study, we identified the influence of Manchurian firs and that of climate change on soil microbial communities in temperate forests and demonstrated the potential of the microbial community as a proactive indicator of vegetation shift due to climate change.

Metagenomic insights for antimicrobial resistance surveillance in soils with different land uses in Brazil

“…Forest soils presented smaller diversity indexes compared to urban and livestock soils (Table S3), which corroborates with previous hypothesis that higher taxonomic diversity is essential to stressed soils maintenance [43]. The main groups found in those soils were Pseudomonadota (Lysobacter, Pseudolabris and Bradyrhizobium), Acidobacteriota (Ocallatibacter) and Bacteroidota (Terrimonas) [44][45][46], with a smaller abundance of Bacillus (Bacillota) species compared to other sites.…”

Microbial community structural and functional differentiation in capped thickened oil sands tailings planted with native boreal species

“…Of note, an increase in the relative abundances of Acidobacteria, Actinobacteriota, Chloroflexi, and Planctomycetota was observed over time in tailings when compared to baseline samples. These taxa are among the most abundant bacterial phyla across soil habitats, which positively correlate with the mineralization of organic matter and nutrient cycling ( Fierer et al, 2010 ; Delgado-Baquerizo et al, 2018 ; Heo et al, 2020 ). The increase in plant growth and resulting carbon input and nutrient turnover in soil likely influenced the tailings microbial community, favoring taxa more adapted to conditions created by vegetation establishment ( Rousk et al, 2010a ; Semchenko et al, 2022 ).…”

“…The microbes associated with plant roots is enormously diverse, and studies on plant-microbe interactions revealed that plants are able to shape their rhizosphere microbiome [1][2][3]. Several strategies have been highlighted to enrich microorganisms beneficial to plant growth and health [4][5][6].…”
