• Biogeochemical cycling and ecological thresholds in a High Arctic lake (Svalbard) 

  Luoto, Tomi P.; Rantala, Marttiina V.; Kivilä, Henriikka; Nevalainen, Liisa; Ojala, Antti E. K. (Springer, 2019)

  Lakes are a dominant feature of the Arctic landscape and a focal point of regional and global biogeochemical cycling. We collected a sediment core from a High Arctic Lake in southwestern Svalbard for multiproxy paleolimnological ...

• Environmental controls on benthic food web functions and carbon resource use in subarctic lakes 

  Kivilä, Henriikka; Luoto, Tomi P.; Rantala, Marttiina V.; Kiljunen, Mikko; Rautio, Milla; Nevalainen, Liisa (Wiley-Blackwell Publishing Ltd., 2019)

  Climate warming and consequent greening of subarctic landscapes increase the availability of organic carbon to the detrital food webs in aquatic ecosystems. This may cause important shifts in ecosystem functioning through ...

• Allochthonous carbon is a major regulator to bacterial growth and community composition in subarctic freshwaters 

  Roiha, Toni; Peura, Sari; Cusson, Mathieu; Rautio, Milla (Nature Publishing Group, 2016)

  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 ...

• Temperature controls organic carbon sequestration in a subarctic lake 

  Rantala, Marttiina V.; Luoto, Tomi; Nevalainen, Liisa (Nature Publishing Group, 2016)

  Widespread ecological reorganizations and increases in organic carbon (OC) in lakes across the Northern Hemisphere have raised concerns about the impact of the ongoing climate warming on aquatic ecosystems and carbon ...

• Applicability and consequences of the integration of alternative models for CO2 transfer velocity into a process-based lake model 

  Kiuru, Petri; Ojala, Anne; Mammarella, Ivan; Heiskanen, Jouni; Erkkilä, Kukka-Maaria; Miettinen, Heli; Vesala, Timo; Huttula, Timo (Copernicus Publications, 2019)

  Freshwater lakes are important in carbon cycling, especially in the boreal zone where many lakes are supersaturated with the greenhouse gas carbon dioxide (CO2) and emit it to the atmosphere, thus ventilating carbon ...
