Abstract Climate change induced shifts in treeline position, both towards higher altitudes and latitudes induce changes soil organic matter. Eventually, matter is transported to alpine subarctic lakes with yet unknown consequences for dissolved (DOM) diversity processing. Here, we experimentally investigate the of by amending temperate lake water soil-derived DOM from above below treeline. We use ultra-high resolution mass spectrometry (FT-ICR MS) track molecular (i.e., chemodiversity), estimate decay measure bacterial growth efficiency. In lakes, increases chemodiversity mainly through enrichment polyphenolic highly unsaturated compounds. These compositional are associated reductions bulk compound-level reactivity reduced Our results suggest that advancement has potential enrich a large number ecosystems less biodegradable DOM, affecting community function potentially altering biogeochemical cycling carbon at high altitudes.

Comparing among spring showing different profile surface water interaction characterized having lower higher CHOS aliphatic compounds.
