FWGNA Information Resources


I. Bibliographies

Bibliography for the Identification of North American Freshwater Snails.  This is Rob Dillon's compilation of guidebooks, keys, monographs, systematic reviews, regional surveys, checklists, and any other published reference material potentially useful for identifying our freshwater gastropod fauna, 1900 - present.  It is available in three forms:

Please feel free to email Rob Dillon (dillonr@cofc.edu) with any additions or corrections you may have for this bibliography.
 

Freshwater Mollusk Bibliography Online.  A searchable database including over 10,000 references on freshwater mollusks worldwide.  This marvelous resource is a collaborative effort by Kevin Cummings (Illinois Natural History Survey), Art Bogan (North Carolina Museum of Natural Sciences), Tom Watters (the Ohio State University Museum of Biological Diversity) and Chris Mayer (Illinois Natural History Survey).  Funded by the National Fish & Wildlife Foundation.

IV. Conservation

See the Synthesis page on the FWGNA site for a proposed system of Incidence Ranks for the 67 species of freshwater gastropods inhabiting Atlantic Drainages from Georgia to the New York line.  From that page you can follow links to several essays I have posted on the FWGNA blog regarding this thorny topic.
