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

Conservation Status Ranks for the 57 species of freshwater gastropods inhabiting Southern Atlantic Drainages were proposed in my blog posts of December 2011, January 2012, and March 2012.  A pdf separate of those three essays is available here. [PDF]

NatureServe - Hit the "NatureServe Explorer" button and search a very nice database for the distribution of any North American freshwater gastropod by state.  The "heritage rank" is an overall estimate of conservation status. But see above.
