Relative importance of soil fertility and microtopography as CO₂ and CH₄ exchange drivers in a northern boreal fen ecosystem.

ABSTRACT: While peatland C cycling is generally well covered, understanding of the role of soil fertility in driving the spatial variation of C fluxes within peatlands remains scattered. Our aim was to examine the relative effects of fertility and microtopography on CO₂ and CH₄ exchange within a boreal fen and to link these effects to the spatial variation in plant and soil attributes. Fertility zones (eutrophic, mesotrophic, oligotrophic) were judged by moss species appearances, and the growing season CO₂ and CH₄ exchange was measured by static chambers for microforms (string, Sphagnum lawn, flark) and fertility zones and by eddy covariance technique for the entire ecosystem in three years. Plant leaf area index, plant functional type biomasses, soil C an
