Intense efforts have been devoted to describe the biochemical pathway of plant sulphur (S) assimilation from sulphate. However, essential information on metabolic regulation of S assimilation is still lacking, such as possible interactions between S

Elevated CO2 does not increase eucalypt forest productivity on a low-phosphorus soil

Experimental evidence from a mature, phosphorous-limited, eucalypt forest finds that aboveground productivity was not significantly stimulated by elevated CO2. Findings suggest that this effect may be limited across much of the tropics. Rising atmosp

International audience; Photosynthesis (GPP), the largest CO2 flux from the land surface, is currently estimated with considerable uncertainty between 100-175 Pg C yr-1. More robust estimates of global GPP could be obtained from the atmospheric budge

The influence of spring geophytes on soil CO2 efflux in a Common beech forest

Autor: Heid, Laura

Publikováno v: Sciences de l'environnement. 2012

To define a forest as carbon sink or source the most important parameter is the soil carbon dioxide efflux (CO2). Several studies have been made to assess more precisely the involved factors. The influence of soil temperature and humidity on soil CO2
