Challenges in elevated CO2 experiments on forests

Trends in Plant Science, 2010
Current forest Free Air CO(2) Enrichment (FACE) experiments are reaching completion. Therefore, it is time to define the scientific goals and priorities of future experimental facilities. In this opinion article, we discuss the following three overarching issues (i) What are the most urgent scientific questions and how can they be addressed?

Effects of elevated CO2 on birch

Vegetatio, 1993
Growth and photosynthesis of birch (Betula pendula Roth) is being investigated as part of a long-term study of the effects of high CO2 on trees. The study commenced in Spring 1991 using seedling, juvenile and mature trees. The results presented in this abstract are preliminary and will be supplemented on the poster by results gathered during the rest ...

Resilience of Fungal Communities to Elevated CO2

Microbial Ecology, 2016
Soil filamentous fungi play a prominent role in regulating ecosystem functioning in terrestrial ecosystems. This necessitates understanding their responses to climate change drivers in order to predict how nutrient cycling and ecosystem services will be influenced in the future.

Forest carbon balance under elevated CO2

Oecologia, 2002
Free-air CO2 enrichment (FACE) technology was used to expose a loblolly pine (Pinus taeda L.) forest to elevated atmospheric CO2 (ambient + 200 µl l-1). After 4 years, basal area of pine trees was 9.2% larger in elevated than in ambient CO2 plots. During the first 3 years the growth rate of pine was stimulated by ~26%.

Growth responses of an alpine grassland to elevated CO2

Oecologia, 1996
Alpine plant species have been shown to exhibit a more pronounced increase in leaf photosynthesis under elevated CO2 than lowland plants. In order to test whether this higher carbon fixation efficiency will translate into increased biomass production under CO2 enrichment we exposed plots of narrow alpine grassland (Swiss Central Alps, 2470 m) to ...

Effects of elevated CO2 on Sitka spruce seedlings

Vegetatio, 1993
The present study on juvenile plants is being carried out in parallel to a study on mature branches (Lee et al 1992) to examine the effects of elevated CO2 (700 ppmv).

Elevated CO2, litter chemistry, and decomposition: a synthesis

Oecologia, 2001
The results of published and unpublished experiments investigating the impacts of elevated [CO2] on the chemistry of leaf litter and decomposition of plant tissues are summarized. The data do not support the hypothesis that changes in leaf litter chemistry often associated with growing plants under elevated [CO2] have an impact on decomposition ...

Effects of elevated CO2 on fen peat biogeochemistry

Science of The Total Environment, 2001
Effects of elevated atmospheric CO2 concentration on northern peatland biogeochemistry was studied in a short-term experiment. Eight intact soil cores (11-cm diameter x 40-cm depth) with Juncus and Festuca spp. were collected from a calcareous fen in north Wales.
