Hello Annelida Group.
I heard of a device which is used to make earthworms come up to the
surface that relies on electrical currents or vibrations. Does anyone
have any information about these "worm rooters" and where I might be
able to find one?
I work on terrestrial salamanders and am interested in trying out
techniques which allow us to determine actual population size of
salamanders in a given area. We use capture-recapture techniques as
well, but recapture rates are often low, making population estimates
Thank you very much for your help. I appreciate any information you
can send me about "worm rooters."
