Methane Stem Fluxes Under Elevated CO2

2021
<p>Tree stems can exchange CH<sub>4</sub> with the atmosphere at rates that can strongly affect GHG budgets at regional scales. However, we do not know those fluxes’ sensitivity to different components of climate change, such as the increase in concentrations of atmospheric CO<sub>2 ...

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?

Balancing carbon storage under elevated CO2

Nature, 2021
A global synthesis of experiments reveals that increases in plant biomass under conditions of elevated CO2 mean that plants need to mine the soil for nutrients, which decreases soil’s ability to store carbon. In forests, elevated CO2 generally seems to greatly increase plant biomass, but not soil carbon.

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.

Rhizosphere Responses to Elevated CO2

2013
Rising atmospheric CO2 levels are predicted to have major consequences on C cycling and the functioning of terrestrial ecosystems. Experimentation during the last two to three decades using a large variety of approaches have provided sufficient information to conclude that the enrichment of atmospheric CO2 may have severe impact on the terrestrial ...

Pyrenoid-core CO2-evolving machinery is essential for diatom photosynthesis in elevated CO2

Plant Physiology, 2023
Abstract Marine diatoms are responsible for up to 20% of the annual global primary production by performing photosynthesis in seawater where CO2 availability is limited while HCO3− is abundant. Our previous studies have demonstrated that solute carrier 4 proteins at the plasma membrane of the diatom Phaeodactylum tricornutum facilitate ...

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 ...

Elevated CO2 increases belowground respiration in California grasslands

Oecologia, 1996
This study was designed to identify potential effects of elevated CO2 on belowground respiration (the sum of root and heterotrophic respiration) in field and microcosm ecosystems and on the annual carbon budget. We made three sets of respiration measurements in two CO2 treatments, i.e., (1) monthly in the sandstone grassland and in microcosms from ...
