Making terrestrial ecosystem models simpler – and better! By Colin Prentice

During the 15 to 18 January 2019, Colin visited Barcelona, having been invited to give a seminar at ICTA (the Institute of Environmental Science and Technology) at the Autonomous University of Barcelona. The seminar was entitled “Making terrestrial ecosystem models simpler – and better!” Several eminent Catalan ecologists were there. In the picture, you can … Continue reading Making terrestrial ecosystem models simpler – and better! By Colin Prentice

A new paper in Ecology Letters: ‘Global photosynthetic capacity is optimized to the environment’. By Colin Prentice

The Rubisco carboxylation capacity, commonly termed Vcmax, is critical in determining how much carbon a plant takes up via photosynthesis. It is a key quantity in Earth System Models (ESMs) used to predict future changes in land carbon uptake under different climate-change scenarios. One big problem, however, is that ESMs typically use fixed values for … Continue reading A new paper in Ecology Letters: ‘Global photosynthetic capacity is optimized to the environment’.

Tracing long-term changes in the relative rate of exchange of CO2 and water between the vegetation and the atmosphere. By Alienor Lavergne

Plant water use efficiency (WUE), i.e. the carbon gained through photosynthesis per unit of water lost through transpiration, is an indicator of the relative rate of exchange of CO2 and water between the vegetation and the atmosphere. At the leaf-level, rising CO2 concentrations tend to increase carbon uptake and to reduce stomatal conductance (in the … Continue reading Tracing long-term changes in the relative rate of exchange of CO2 and water between the vegetation and the atmosphere.
