SPATIAL AND TEMPORAL PERFORMANCE OF THE MINIFACE (FREE AIR CI_2 ENRICHMENT)SYSTEM ON BOG ECOSYSTEMS IN NORTHERN AND CENTRAL EUROPE

摘要

The Bog Ecosystem Research Initiative(BERI)project was initiated to investigate, at five climatically different sites across Europe, the effect of elevated CO_2 and N deposition on the net exchange of CO_2 and CH_4 between bogs and the atmosphere, and to study the effects of elevated CO_2 and N deposition on the plant biodiversity of bog communities. A major challenge to investigate the effects of elevated CO_2 on vegetation and ecosystems is to apply elevated CO_2 concentrations to growing vegetation without changing disturb the natural conditions like climate and radiation.
