Effects of N and P fertilization on the greenhouse gas exchange in two nutrient-poor peatlands (2009)

M. Lund, T. R. Christensen, M. Mastepanov, A. Lindroth, L. Ström

Peatlands are important ecosystems in the context of biospheric feedback to climate change, due to the large storage of organic C in peatland soils. Nitrogen deposition and increased nutrient...

Annual carbon gas budget for a subarctic peatland, northern Sweden (2009)

K. Bäckstrand, P. M. Crill, M. Jackowicz-Korczyñski, M. Mastepanov, T. R. Christensen, D. Bastviken

Temperatures in the Arctic regions are rising, thawing permafrost and exposing previously stabile soil organic carbon (OC) to decomposition. This can result in that northern latitude soils which have...

Effects of N and P fertilization on the greenhouse gas exchange in two northern peatlands with contrasting N deposition rates (2009)

M. Lund, T. R. Christensen, M. Mastepanov, A. Lindroth, L. Ström

Sectoral approaches to improve regional carbon budgets (2008)

Smith, P., Nabuurs, G.J., Janssens, I.A., Reis, S ., Marland, G., Soussana, J.F., ...

Humans utilise about 40% of the earth¿s net primary production (NPP) but the products of this NPP are often managed by different sectors, with timber and forest products managed by the forestry...

Climate change and Arctic ecosystems: 1. Vegetation changes north of 55 degrees N between the last glacial maximum, mid-Holocene, and present (2003)

Bigelow, N. H., Brubaker, L. B., Edwards, M. E., Harrison, S. P., Prentice, I. C., Anderson, P. M., ...

A unified scheme to assign pollen samples to vegetation types was used to reconstruct vegetation patterns north of 55°N at the last glacial maximum (LGM) and mid-Holocene (6000 years B.P.). The...
