"Plant respiration: lessons from high latitudes for ecosystem carbon balance modelling"

Presented by Paul P. Gauthier, Princeton University

Wednesday, March 9, 2016, 11:00 am — John Dunn Seminar Room, Bldg. 463

Climate-mediated changes in ecosystem C balance are accepted as an important component of the biosphere response to climate change. Plant respiration and photosynthesis are major drivers of this balance but our lack of understanding of the controls and constrains surrounding their interaction stalls our capacity to predict future ecosystem changes. Using a new O2 isotopes method for measuring leaf functional traits, I will present a new approach to estimate the rate of leaf respiration in the light and its biochemical origin in temperate and arctic plants. The role of plant respiration as a key player for plant adaptation will also be discussed in the context of plant respiration modelling.
