<p class="MsoNormal">Yes, from what I understand, 13C could be informative.<o:p></o:p></p>

<p class="MsoNormal">BUT, I know for soils they can’t be oven dried for stable carbon isotope analyses - what about leaf litter?<o:p></o:p></p>

<p class="MsoNormal">To contribute to our discussions going on, I pass along the litterfall graph that Sarah prepared that compares litterfall YTD vs. the averages since the CTE started in 2002. There was an immense amount during one single fortnight in May.
It was so much that it took all the staff to collect it all. I spoke to John Bithorn yesterday and he told me he was many species, not just a few, that contributed to the peak. We'll keep you posted as more data are added. We are also analyzing the data
set on palm litter, too.<o:p></o:p></p>
