GASTROPOD CARE SOP# = Moll3 PURPOSE: To describe methods of care for gastropods. POLICY: To provide optimum care for all animals. RESPONSIBILITY: Collector and user of the animals. If these are not the same person, the user takes over responsibility of the animals as soon as the animals have arrived on station.

Examining Patterns of Genetic Variation in Canadian Marine Molluscs Through DNA Barcodes
Examining patterns of genetic variation in Canadian marine molluscs through DNA barcodes by Kara Layton A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Integrative Biology Guelph, Ontario, Canada © Kara Layton, January, 2012 ABSTRACT Examining patterns of genetic variation in Canadian marine molluscs through DNA barcodes Kara Layton Advisor: University of Guelph, 2013 Professor P.D.N Hebert In this thesis I investigate patterns of sequence variation at the COI gene in Canadian marine molluscs. The research presented begins the construction of a DNA barcode reference library for this phylum, presenting records for nearly 25% of the Canadian fauna. This work confirms that the COI gene region is an effective tool for delineating species of marine molluscs and for revealing overlooked species. This study also discovered a link between GC content and sequence divergence between congeneric species. I also provide a detailed analysis of population structure in two bivalves with similar larval development and dispersal potential, exploring how Canada’s extensive glacial history has shaped genetic structure. Both bivalve species show evidence for cryptic taxa and particularly high genetic diversity in populations from the northeast Pacific. These results have implications for the utility of DNA barcoding both for documenting biodiversity and broadening our understanding of biogeographic patterns in Holarctic species. Acknowledgements Firstly, I would like to thank my advisor Dr. Paul Hebert for providing endless guidance and support during my program and for greatly improving my research. You always encouraged my participation in field collections and conferences, allowing many opportunities to connect with colleagues and present my research to the scientific community. -
