Recent Changes in Global Photosynthesis and Terrestrial Ecosystem Respiration Constrained From Multiple Observations

Photosynthesis and Global Change Can Climate Driven Changes in Photosynthesis Be Used to Predict Changes in the Rate and Temperature Sensitivity of Ecosystem Respiration?

INTRODUCTION Terrestrial ecosystem respiration releases approximately 60 Pg carbon into the atmosphere anually (Schimel et al 1995). This is a relatively large amount in comparison to the 7.1 Pg carbon released per year from fossil fuel combustion, cement production and land use changes. Terrestrial ecosystem respiration thus plays a critical role in determining net CO2 fluxes into the atmosphe...

Divergent apparent temperature sensitivity of terrestrial ecosystem respiration Bing

Aims Recent studies revealed convergent temperature sensitivity of ecosystem respiration (Re) within aquatic ecosystems and between terrestrial and aquatic ecosystems. We do not know yet whether various terrestrial ecosystems have consistent or divergent temperature sensitivity. Here, we synthesized 163 eddy covariance flux sites across the world and examined the global variation of the apparen...

Photosynthesis and Respiration in Cyanobacteria

Cyanobacteria are among the very few groups that can perform oxygenic photosynthesis and respiration simultaneously in the same compartment, and some cyanobacterial species are able to fix nitrogen. This combination of metabolic pathways is unusual and this metabolic flexibility may be responsible for the evolutionary hardiness of the cyanobacteria and their ability to thrive under a wide range...
