dc.description.abstract | In the subarctic region, climate warming and permafrost thaw are leading to emergence of ponds
and to an increase in mobility of catchment carbon. As carbon of terrestrial origin is increasing in
subarctic freshwaters the resource pool supporting their microbial communities and metabolism is
changing, with consequences to overall aquatic productivity. By sampling different subarctic water
bodies for a one complete year we show how terrestrial and algal carbon compounds vary in a range
of freshwaters and how differential organic carbon quality is linked to bacterial metabolism and
community composition. We show that terrestrial drainage and associated nutrients supported higher
bacterial growth in ponds and river mouths that were influenced by fresh terrestrial carbon than in large
lakes with carbon from algal production. Bacterial diversity, however, was lower at sites influenced by
terrestrial carbon inputs. Bacterial community composition was highly variable among different water
bodies and especially influenced by concentrations of dissolved organic carbon (DOC), fulvic acids,
proteins and nutrients. Furthermore, a distinct preference was found for terrestrial vs. algal carbon
among certain bacterial tribes. The results highlight the contribution of the numerous ponds to cycling
of terrestrial carbon in the changing subarctic and arctic regions. | |
