Snailers,
This fall & winter I'm working with Ken & Janet Storey -
http://www.kenstoreylab.com/ - on freeze tolerance in Cepaea nemoralis.
The plan is to collect specimens for study after there are a few cm of
frost in the soil, so we'll know that the ones analysed are fully
prepared for winter. I've embedded a metre-square cage of window screens
in garden soil, and will be loading this with snails to excavate so we
can see how deeply each size/age class goes into the soil, but I also
want to know when wild snails seen under cover objects go away, or
don't, when it gets cold.
So my question is - are there studies, or is there experience, about how
skittish snails are about having cover objects turned? I don't want
snails to disappear from cover I'm checking because I was turning the
cover too often, rather than because they felt it was time to dig in or
go elsewhere to hibernate.
There probably isn't a study where marked snails were followed under an
array of cover objects which were turned at a range of intervals, but
I'd like to know what's known or suspected. I haven't googled the
subject yet, so even key phrases to search on would be helpful.
