The Popular Clammer

a newsletter about freshwater Unionoid mussels in Canada



living Ligumia nasuta from Lyn Creek, Lyn, Ontario[living Ligumia nasuta from Lyn Creek]
August 2006. Green algae cover the posterior portion of the shell that usually protrudes from the substrate.




We launched The Popular Clammer as our report to the 2007 Ontario Freshwater Mussel Recovery Team Meeting. Our title comes from a political discussion in Walt Kelly's Pogo strip, in which the preferences of "the popular clammer" were contrasted to those of "our roisterers." If you think an electronically distributed newsletter about freshwater mussel research and conservation in Canada is a worthwhile idea, be sure that your activities, interests, and discoveries are adequately represented in further issues, which will be published when there's sufficient material assembled. We'll draw up a subscription list of those who let us know that they want to be notified of future numbers. Please submit plans and reports of conservation activities, accounts of events, abstracts of publications, results, stories, trivia, poems, comments, photos, etc. to me at Bishops Mills Natural History Centre, RR#2 Bishops Mills, Ontario, K0G 1T0. --Frederick W.
