1. Carbon in Boreal Streams : Isotopic Tracing of Terrestrial Sources
Sammanfattning : The boreal biome comprises vast areas of coniferous forests, dotted with millions of peatlands. Plants harbouring these ecosystems fix CO2 from the atmosphere, which is later incorporated into the vegetation biomass and subsequently buried in soils. LÄS MER
2. Bacterial use of allochthonous organic carbon for respiration and growth in boreal freshwater systems
Sammanfattning : Aquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere.

3. The role of inland waters in the carbon cycle at high latitudes
Sammanfattning : Understanding the drivers of climate change requires knowledge about the global carbon (C) cycle. Although inland waters play an important role in the C cycle by emitting and burying C, streams and lakes are in general overlooked in bottom-up approached C budgets. LÄS MER
4. A GIS-based landscape analysis of dissolved organic carbon in boreal headwater streams
Sammanfattning : In boreal catchments, stream water chemistry is influenced and controlled by several landscape factors. The influence of spatially distributed variables is in turn dependent on the hydrological scale. LÄS MER
5. Spatiotemporal streamflow variability in a boreal landscape : Importance of landscape composition for catchment hydrological functioning
Sammanfattning : The understanding of how different parts of a landscape contribute to streamflow by storing and releasing water has long been a central issue in hydrology. Knowledge about what controls streamflow dynamics across landscapes can further our understanding of how catchments store and release water, facilitate predictions for ungauged catchments, and improve the management of water quality and resources.
