Photosynthesis and biomass both influence plant respiration—a new study by Alessio Collalti, Colin Prentice et al.

One of the greatest challenges in quantifying the global carbon balance is to correctly estimate how much carbon is accumulated in biomass versus how much is returned to the atmosphere as product of plant respiration. Alessio, Colin and others tackle this challenge in the recent paper published in Global Change Biology (Collalti et al., 2019). … Continue reading Photosynthesis and biomass both influence plant respiration—a new study by Alessio Collalti, Colin Prentice et al.

REALM research update from Dr Keith Bloomfield

Photosynthesis may be light-dependent, but what about other (and co-related) climate variables such as temperature?  Is it possible to describe the environmental dependencies of gross primary productivity (GPP)?  Moving outside the controlled conditions of a growth chamber or greenhouse, attempting to answer such questions for natural ecosystems becomes complicated.  Further complexity is generated by plant … Continue reading REALM research update from Dr Keith Bloomfield

ESA Living Planet Symposium: The P Model as a satellite-driven tool for GPP prediction.

The European Space Agency (ESA) Living Planet Symposium was held in Milan, Italy from the 13th to 17th May 2019. The event’s focus on contributions of space technology to science and society and attracted more than 4000 people in the world’s biggest Earth observation conference to date. Prof Colin Prentice and doctoral candidate Alison Prior … Continue reading ESA Living Planet Symposium: The P Model as a satellite-driven tool for GPP prediction.

REALM team members take a break from research and teach on the MRes summer school at Imperial. By David Sandoval and Dr Rodolfo Nobrega

For 2 days we presented, discussed and analysed flux measurements in the frame of the summer school of the MRes Ecosystem and Environmental Changes master course. Our main goal was to make the students aware of the measurements and post-processed analysis of the flux data. In times where networks such as FLUXNET is making incredible ready-to-use … Continue reading REALM team members take a break from research and teach on the MRes summer school at Imperial.

Prentice Lab at the EGU General Assembly 2019. By Alison Prior

The European Geosciences Union (EGU) General Assembly 2019 gathered over 16,000 scientists from 113 countries in Vienna earlier this month. The Prentice Lab showcased their work in sessions ranging in topic from mountain climatology and hydrology to soil plant atmosphere interactions and terrestrial ecosystem carbon and water response.  The Prentice Lab’s research (@LabPrentice) centres around explaining and predicting ecosystem carbon and water exchange, and global phytogeographic patterns, and accounting for the functional diversity of terrestrial plant communities. The work presented at EGU highlights some of the lab’s latest results in modelling … Continue reading Prentice Lab at the EGU General Assembly 2019. By Alison Prior

Is net primary production of forests a constant fraction of gross primary production? 20 years on and the answer is no, it’s not that simple. By Colin Prentice

Colin has a new paper out, published in Tree Physiology with Dr Alessio Collalti from Italy. The aim of the paper was to test the reliability and accuracy of a long-held hypothesis due to Waring et al. (1998) that the NPP to GPP ratio is constant (at 0.47). For twenty years, researchers have been trying to … Continue reading Is net primary production of forests a constant fraction of gross primary production? 20 years on and the answer is no, it’s not that simple.

Have we been underestimating the impacts of drought on terrestrial primary production?

Dr Beni Stocker and Colin have teamed up again, alongside other long-standing collaborators on a new research paper published in Nature Geoscience, that demonstrates that current methods that are based on satellite data have been underestimating the impacts of drought on vegetation and the carbon cycle. Obtaining accurate estimates of photosynthesis and vegetation productivity across … Continue reading Have we been underestimating the impacts of drought on terrestrial primary production?
