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).
