    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Boreal and subarctic peatlands contain 20-30 f the world's soil organic carbon, and if growing, they constitute sinks for atmospheric CO2. We hypothesized that even in the nutrient-poor bog environment, elevated CO2 would stimulate Sphagnum growth more than vascular plant growth, thereby improving Sphagnum's competitive strength and enhancing carbon (C) sequestration. Free-air carbon dioxide enrichment (FACE) experiments took place on predominantly ombrotrophic peatbog-lawns in Finland (FI), Sweden (SW), The Netherlands (NL), and Switzerland (CH). After 3 yr of treatment, increased CO2 concentration (560 ppm on volume basis) had no significant effect on Sphagnum or vascular plant biomass at either site. This research suggests that, just as with other nutrient-poor ecosystems, increased atmospheric CO2 concentrations will have a limited effect on bog ecosystems.
