Description:
I am most interested in applying isotopic techniques to analysis of the
C budget of the FACE site, but unclear about what territorial boundaries
I may be stepping over. In any case, I hope to at least visit the
FACE site--at best to collect samples of tissue and respired CO2.
I gather that we may have more freedom to work with the prototype than
with the replicated set, therefore I'd like to collect an increment core
or two there. Alternatively, I could cut a branch with tree rings predating
the beginning of the experiment. My guess is that the isotopic data
will show a consistent upward tick in ci holding the difference, ca-ci,
constant. This is what we saw in the absence of fertilization across
the last hundred years, and what we have seen across elevational transects
of CO2 partial pressure. It may help to explain the disappearance
of the CO2 fertilization at the FACE sites as well. My
concern is that it's already been done, or someone is planning on doing
it.
