In situ effects of elevated CO2 on plants and insects [PDF]

open access: yes, 2005
10.1 Mature trees in a CO2 enriched world Mature (app. 100 years old) temperate forest trees were exposed to an increased atmospheric CO2 concentration for four growing seasons at the Swiss Canopy Crane site (SCC) near Basel (Switzerland) using web ...

Influence of elevated carbon dioxide and ammonium nutrition on growth and nitrogen metabolism in wheat (Triticum aestivum)

open access: yesThe Indian Journal of Agricultural Sciences, 2016
Growth under elevated CO2 (EC) conditions inhibits nitrate (NO3-) assimilation in crop plants, hence ammonium (NH4+) nutrition is beneficial compared to NO3– nutrition under EC conditions.

Forest succession at elevated CO2 [PDF]

open access: yes, 2002
We tested hypotheses concerning the response of forest succession to elevated CO2 in the FACTS-1 site at the Duke Forest. We quantified growth and survival of naturally recruited seedlings, tree saplings, vines, and shrubs under ambient and elevated CO2. We planted seeds and seedlings to augment sample sites.

Respiratory Oxygen Uptake Is Not Decreased by an Instantaneous Elevation of [CO2], But Is Increased with Long-Term Growth in the Field at Elevated [CO2] [PDF]

open access: yesPlant Physiology, 2004
Abstract Averaged across many previous investigations, doubling the CO2 concentration ([CO2]) has frequently been reported to cause an instantaneous reduction of leaf dark respiration measured as CO2 efflux. No known mechanism accounts for this effect, and four recent studies have shown that the measurement of respiratory CO2 efflux is ...

Impact of rising CO2 on emissions of volatile organic compounds: isoprene emission from Phragmites australis growing at elevated CO2 in a natural carbon dioxide spring. [PDF]

open access: yes, 2004
Isoprene basal emission (the emission of isoprene from leaves exposed to a light intensity of 1000 mmol m-2 s-1 and maintained at a temperature of 30 â C) was measured in Phragmites australis plants growing under elevated CO2 in the Bossoleto CO2 ...

The transcriptome of Populus in elevated CO2 reveals increased anthocyanin biosynthesis during delayed autumnal senescence [PDF]

open access: yes, 2010
The delay in autumnal senescence that has occurred in recent decades has been linked to rising temperatures. Here, we suggest that increasing atmospheric CO2 may partly account for delayed autumnal senescence and for the first time, through transcriptome

Various growth strategies of yellow birch seedlings in multiple-abiotic factor changing environments

open access: yesPlant, Soil and Environment, 2010
Elevated CO2 concentration, light intensity and soil-sterile conditions are thought as three of the most important factors to affect plant growth and development. However, their combined physiological effect on plants is unknown so far. In this study, we

Response of mature Norway spruce (Picea abies) to elevated atmospheric CO² [PDF]

open access: yes, 2014
The aim of this thesis was to identify pathways and rates of C allocation in tall forest trees, and to identify effects of elevated CO2 on respiratory processes and root growth.

Free atmospheric CO2 enrichment increased above ground biomass but did not affect symbiotic N2-fixation and soil carbon dynamics in a mixed deciduous stand in Wales [PDF]

open access: yes, 2011
Through increases in net primary production (NPP), elevated CO2 is hypothesizes to increase the amount of plant litter entering the soil. The fate of this extra carbon on the forest floor or in mineral soil is currently not clear.

Effect of elevated CO2 and temperature on growth and yield contributing parameters of pea (Pisum sativum L.) crop

open access: yesJournal of Agrometeorology, 2019
An experiment was conducted during 2014 and 2015 at Solan, Himachal Pradesh to study the effect of elevated CO2 (eCO2) and temperature (eT) on growth and yield contributing parameters of pea (Pisum sativum L.) crop under four conditions of CO2 and ...
