I would like to set out establishing a pretty specific range for Pyganodon lacustris, a (relatively) recently re-recognized American mussel species. I know that it is a freshwater mussel species that was proved distinct from other similar species (Pyganodon grandis and Pyganodon cataracta) through both morphological and allozymic evidence presented by Hoeh and Burch in a 1989 Walkerana paper. Does anyone know if an effort has been made to establish the specific range of the species? Many examples of "P. cataracta" have been listed from western NY, but I have been led through research to wonder if they might all be misidentified P. lacustris? If anyone has done any work in this area or know of people who might be helpful with this subject, I would love to hear from you. -Thanks, Kevin Czaja PS, the better direct email is at: [log in to unmask] (my Conch-L registered address blocks out unfamiliar addresses). ---------------------------------------------------------------------- [log in to unmask] - a forum for informal discussions on molluscs To leave this list, click on the following web link: http://listserv.uga.edu/cgi-bin/wa?SUBED1=conch-l&A=1 Type your email address and name in the appropriate box and click leave the list. ----------------------------------------------------------------------
