To the FWGNA group:
We were pleased to receive email notification late last week that the
proceedings of the Vienna Symposium on Molluscan
Biodiversity and Conservation have found their way to press.
The table of contents is available as a PDF download from
the FWGNA web site. Longtime members of this list may remember that I
offered a report on
the Vienna Symposium upon my return in September 2001. Although the
original symposium did not include any talk specifically dealing with
freshwater gastropods, the recently published volume features a paper on the
Lake Tanganyika gastropod fauna by Todd and colleagues. It is available
as a special publication of the Journal of Conchology,
contact Dr. Mary Seddon for the details:

I do think we've seen increased awareness of molluscan
conservation issues in recent years. In fact, I personally have a hard
time keeping track of all the books, articles, and other resources documenting
the downward spiral. Herewith is a brief bibliography:
Brown, K. M & P. D. Johnson (in press) The conservation status of
freshwater Pleurocerid gastropods in the United States. American Malacological Bulletin. This work is based on
the keynote address for the 2002 Charleston symposium on the biology and
conservation of freshwater gastropods. Should see publication soon!
Lydeard, C. et al. (2004) The global decline of nonmarine
mollusks. BioScience 54: 321 - 330. Chuck
Lydeard is joined by a gang of 15 coauthors in this
general review featuring three "highlighted faunas:" Pacific land
snails, unionoid mussels, and spring snails of the
Australian outback, as well as conservation strategies.
Black, S. H., M. Shepard & M. M. Allen (2001) Endangered invertebrates: the case for greater
attention to invertebrate conservation. Endangered Species Update 18: 42
- 50. Scott Hoffman Black is the executive director of the Xerces Society, an advocacy group for invertebrate
conservation. One could accuse Xerces of being
biased toward insects, but so was God. Scott's article does include
references to freshwater mollusks, and may be available in PDF format from the
Xerces web site.
Neves, R.J., A E. Bogan,
J. D. Williams, S. A. Ahlstedt, and P. W. Hartfield (1997) Status of aquatic mollusks in
the southeastern United States: A downward spiral of diversity. Chapter 3
in Aquatic Fauna in Peril: the Southeastern Perspective (Benz &
Collins, eds.) Southeast
Aquatic Research Institute Publication 1. This 42-page work
features the most complete review of the conservation status of any regional
freshwater gastropod fauna.
Lydeard, C. & R. L. Mayden
(1995) A diverse and endangered aquatic
ecosystem of the southeast United States. Conservation Biology 9:
800-805. This work includes a comprehensive review of the Mobile Basin
gastropod fauna, past and present.
If anybody would like to recommend additional resources generally relevant to
the conservation of freshwater gastropod faunas, by all means bring them to my
attention.
And keep in touch,
Rob
