[LTER-luq] Final litterfall graph (until we add palms) Can stable carbon isotopes be run on oven dried leaf litter? or does it have to be air dried?

[Deborah J Lodge]

Yes, from what I understand, 13C could be informative.

BUT, I know for soils they can’t be oven dried for stable carbon isotope analyses - what about leaf litter?

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.
