Project description
Impact of microbes on soil respiration in the Alps
Soil respiration (SR) is an important terrestrial carbon source, which is linked to temperature and thus expected to exacerbate climate change. Previous studies in mountainous regions, where SR was measured along altitudinal gradients, faced significant differences in environmental conditions and thus distinct faunal and microbial communities in soil samples from various altitudes. The EU-funded ALSORES project aims to reveal the pure effect of altitude, but also of land use and climate change on soil microbial and invertebrate communities and how microbial and invertebrate activities shape SR. Researchers will also investigate the advantages of using intracellular DNA rather than the generally studied environmental DNA as a proxy for microbial activity and SR.
Objective
The belowground production of CO2 in soil (soil respiration, SR) represents an important terrestrial carbon source. Being correlated with soil temperature, SR is expected to exacerbate climate change. In addition, SR is expected to change considerably and in a patchy manner especially within the Alpine area, reflecting the effects of altitude, land use and climatic conditions. Previous studies measuring SR along altitudinal gradients, however, struggled with strong differences in environmental influences and with distinct unique faunal and microbial communities among samples.
The grand ambition of ACTI-RESP is to provide in-depth knowledge and quantitative information on how microbial and invertebrate communities are influenced by altitude, land use and climate change, and on how microbial activity shapes SR. To quantify the pure effect of altitude and to investigate the effects of climate and land use, I will combine field observations and a manipulative experiment within terraXcube, a facility allowing manipulations of multiple conditions including air pressure to mimic different elevations.
Thereby, I aim to further test the advantages of studying intracellular DNA (iDNA) as opposed to the generally studied environmental DNA (eDNA). Being composed by considerable amounts of extracellular DNA, eDNA does not only contain information about intact and active cells (intracellular DNA, iDNA) but also about extracellular DNA from species that might not be recently present. Here, I will study microbial agents actually shaping SR by extracting iDNA, by performing qPCR and 16S rRNA sequencing and by comparing the results to eDNA as well as RNA-based results.
In doing so, I aim to
- define climate change-related alterations in SR
- jointly examine soil invertebrates and microorganisms
- firstly describe the pure altitude effect on microbial SR, activity and community patterns
- test iDNA quantification as a proxy for microbial activity and SR
