Biographical Summary of Report Writer

Dr. Dwayne A.W. Lepitzki is an independent biologist who has been on contract with Parks Canada since 1994 working on other aquatic projects (giant liver flukes, amphibians, thermal spring micro and macroinvertebrates) as well as the Banff Springs Snail. He has a B.Sc. (1st class honours) in Zoology from the University of Alberta (1983), an M.A. in Zoology from Southern Illinois University at Carbondale (Cooperative Wildlife Research Laboratory) (1986), and a Ph.D. in Parasitology from McGill University (1993). His Ph.D. dissertation entitled “Epizootiology and transmission of snail-inhabiting metacercariae of the duck digeneans Cyathocotyle bushiensis and Sphaeridiotrema globulus” involved work on aquatic snail communities in southern Quebec and southeastern Ontario. His undergraduate degree involved work on terrestrial snails and slugs acting as intermediate hosts for ungulate parasites. He has been the Principal Investigator on the Parks Canada research and recovery program for the Banff Springs Snail since 1996, wrote the original COSEWIC status report on the snail in 1997 and the Alberta status report on the snail in 2002, assigned preliminary status ranks to all terrestrial and aquatic gastropods in Alberta in 2001, is an inaugural member of the Banff Springs Snail Recovery Team, was the first author on the Parks Canada approved Resource Management Plan for the Recovery of the Snail (2002), and is the first author on the Recovery Strategy and Action Plan for the snail (2007). He has authored or co-authored over 15 peer reviewed, published papers, over 40 internal reports including Environmental Assessments, and has presented his research findings at over 30 regional, national, and international conferences from Victoria, British Columbia to Liverpool England. In 2005 he was appointed to the Molluscs SSC of COSEWIC.


Collections Examined

The original COSEWIC status report (Lepitzki 1997a) provided a complete list of museum authorities who were consulted for specimens and collections. To that list can be added: Gary Rosenberg (Academy of Natural Sciences, Philadelphia, PA) and J.B. Burch (University of Michigan).
