The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling. [PDF]

open access: yes, 2013
Terrestrial higher plants are composed of roots and shoots, distinct organs that conduct complementary functions in dissimilar environments. For example, roots are responsible for acquiring water and nutrients such as inorganic nitrogen from the soil ...

Selected breakpoints of net forest carbon uptake at four eddy-covariance sites

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2021
Extensive studies are available that analyse time series of carbon dioxide and water flux measurements of FLUXNET sites over many years and link these results to climate change such as changes in atmospheric carbon dioxide concentration, air temperature ...

The differential ability of two species of seagrass to use carbon dioxide and bicarbonate and their modelled response to rising concentrations of inorganic carbon

open access: yesFrontiers in Plant Science, 2022
Seagrass meadows are one of the most productive ecosystems on the planet, but their photosynthesis rate may be limited by carbon dioxide but mitigated by exploiting the high concentration of bicarbonate in the ocean using different active processes ...

The lifetime of excess atmospheric carbon dioxide [PDF]

open access: yes, 1994
We explore the effects of a changing terrestrial biosphere on the atmospheric residence time of CO2 using three simple ocean carbon cycle models and a model of global terrestrial carbon cycling.

Carbon Dioxide Uptake by Hydrated Lime Aerosol Particles [PDF]

open access: yesAerosol Science and Technology, 2004
The reaction of the greenhouse gas, CO2, with Ca(OH)2 was explored using single-particle Raman spectroscopy to track the chemical reaction. Single particles were levitated in an electrodynamic balance (EDB) to maintain the particle in a laser beam. The levitation voltage provided gravimetric data. The humidity in the EDB chamber was varied to determine

Towards a universal model for carbon dioxide uptake by plants [PDF]

open access: yesNature Plants, 2017
Gross primary production (GPP)-the uptake of carbon dioxide (CO2) by leaves, and its conversion to sugars by photosynthesis-is the basis for life on land. Earth System Models (ESMs) incorporating the interactions of land ecosystems and climate are used to predict the future of the terrestrial sink for anthropogenic CO21 .

Carbon dioxide level and form of soil nitrogen regulate assimilation of atmospheric ammonia in young trees. [PDF]

open access: yes, 2015
The influence of carbon dioxide (CO2) and soil fertility on the physiological performance of plants has been extensively studied, but their combined effect is notoriously difficult to predict.

The ocean carbon sink – impacts, vulnerabilities and challenges [PDF]

open access: yes, 2014
Carbon dioxide (CO2) is, next to water vapour, considered to be the most important natural greenhouse gas on Earth. Rapidly rising atmospheric CO2 concentrations caused by human actions such as fossil fuel burning, land-use change or cement production ...

Adsorption of Methane and Carbon Dioxide on Activated Carbon and ZIF-8 (Zeolitic Imidazolate Framework)

open access: yesChemical Engineering Transactions, 2018
Comparative adsorption of methane and carbon dioxide on activated carbon and ZIF-8 (Zeolitic Imidazolate Framework) at 35 °C and up to 100 psi was made.
