David Goodwin at Denison University took the lead on setting this up:

The sclerochronological community is pleased to announce the Sclerochronology Listserve.  This listserve is a discussion list for all those interested in the field of sclerochronology.  It exists to promote electronic communication among sclerochronologists (AKA: biologists, ecologists, geologists, and oceanographers).  While intended primarily for professionals and students, the sclerochronology listserve welcomes participation and input from all those interested in the field.
 

What, you ask, is sclerochronology?  Well...
 
Sclerochronology is the study of physical and chemical variations in the accretionary hard tissues of organisms, and the temporal context in which they formed. Sclerochonology focuses primarily upon growth patterns reflecting annual, monthly, fortnightly, tidal, daily, and sub-daily increments of time entrained by a host of environmental and astronomical pacemakers. Familiar examples include daily banding in reef coral skeletons or annual growth rings in mollusk shells. Sclerochronology is analogous to dendrochronology, the study of annual rings in trees, and equally seeks to deduce organismal life history traits as well as to reconstruct records of environmental and climatic change through space and time.
 
To subscribe to the list:
 
Send a mail to mailserv@denison.edu containing the following line in the message body:
 
subscribe sclerochronology name at university.com
 
where "name at university.com" is your e-mail address.
 
You will then receive an e-mail asking for confirmation that you indeed wish to join the list.  After responding to the confirmation e-mail you will receive another message detailing how to post new messages as well as how to unsubscribe.

Regards,
Dave Goodwin
