Dear colleagues, I hope someone can help .
Having trawled through the archives, it appears that my query has not been
I have very recently collected some modern land snails for future stable
isotope analysis of carbon and oxygen from the shell carbonate, maybe the
organic too but definately the inorganics. The animals were frozen
straight away to kill them but are now in 95% alcohol, but they have only
been in it a couple of weeks. The bodies are still in the shells at
present since returning from the field. It appears that I should preserve
them in ethanol instead - is this correct?
Also, once I have removed the body, what medium is best to preserve the
shell in until I can properly clean them and store them dry (obviously I
don't want any rotting should there be traces of the body left behind by my
inexperienced winkling!) or is this not a concern.
Thank you very much in advance for any advice received, it is much
