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.
Wood density—dry mass per fresh volume (g cm-3)—is one of the most commonly assesed trait in plant ecology and ecophysiology. It is easy to measure and it indicates the amount of carbon a plant invests in wood, which is an important component of plant carbon budget. At the same time, wood density is just one … Continue reading Wood density under a microscope. By Kasia Ziemińska
In today’s issue of Science, Bastin et al. hit back at critics (no less than four technical comments and three letters published today draw attention to errors and/or omissions in their original paper!). They have, at least, withdrawn their misleading claim that tree planting is the “best solution” to climate change. They say that they … Continue reading Alternative facts and carbon cycle. By Colin Prentice
The role of trees in combating climate change has been receiving a lot of media attention lately, with the impression given that simply planting more trees is all we need to do. But it isn’t quite so straight forward. César Terrer, a former PhD student of Colin’s, has just had a paper published with Colin … Continue reading Trees will help us to fight climate change, but only if we protect them. By César Terrer
For climate scientists and climate policy wonks, the big publishing event of 2018 was the release of the Intergovernmental Panel on Climate Change (IPCC) Special Report on “Global Warming of 1.5˚C” produced in response to the 2015 Paris Agreement . At the Paris meeting of the Conference of the Parties (COP) to the United Nations … Continue reading One and a half degrees of confusion. By Prof. Colin Prentice
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
Monitoring of grassland management in long-term ecological experiments (LTEs) at an ecosystem level is necessary due to potential impacts on biomass production in response to climate change. Knowledge gaps remain about how grasses with different nutrients and management affected the leaf chlorophyll content (CC) and intrinsic photosynthetic capacity (maximum carboxylation rate: Vcmax) in grassland ecosystem. … Continue reading Mapping managed grassland ecosystem from space and modelling.
