Current Research: Ecosystem physiology and carbon/water dynamics

Research during this first year will be focused on modelling the role of Biological Volatile Organic Compounds (BVOC’s) in the processing of carbon produced by photosynthesis. This involves the inclusion in the process based biogeochemical model GOTILWA+ of several different models for BVOC emissions.

Collaboration with researchers from the CEA (Paris, France) will allow for research on the effects of scaling up terrestrial system process modelling from the stand level to a global scale. This collaboration will take place throughout Trevor’s contract, however, it will be concentrated during a secondment at the CEA (again, see schedule attached for more detail). This joint project will also involve the comparison of GOTILWA+ with a process based ecosystem model which has been developed at the CEA.

Later research will continue on with model development in light of the knowledge gained from the comparison with the model developed at CEA. Half way through the year, the results of both the model comparisons and the research on the effect of BVOC’s should be ready to be published. Research efforts will then be directed towards gaining a better understanding of functional respiration. Particular attention will be paid to heterotrophic respiration, in the form of the decomposition of soil organic matter, and with an emphasis on drought conditions. The University of Amsterdam (Amsterdam, The Netherlands) will host Trevor during his second, 3-month secondment in order to exchange approaches to problems of scaling, and also hydrology driven respiration.

This project (ESRVII) contributes to the science objective 1 (Quantify feedbacks in the global carbon cycle) of GREENCYCLES and has links to the projects of Raquel (ESR I) and Sönke (ERI).
