Examining patterns of genetic variation in Canadian marine molluscs through DNA barcoding

I’ve always had a keen interest in marine science and received my BSc (Honours) in Marine and Freshwater Biology from the University of Guelph. I became interested in the applications of DNA barcoding after partaking in an Arctic Ecology field course in Churchill, Manitoba, Soon after I began graduate studies with Dr. Paul Hebert at the Biodiversity Institute of Ontario and had the opportunity to work with my favourite marine group- the Mollusca. Throughout both degrees I participated in field work in sub-Arctic, temperate and tropical locations and have had the opportunity to present my MSc research at both national and international conferences.

Marine Biodiversity, MB-07: A barcode reference library for Canada's Arctic invertebrates

Layton 2I used DNA barcoding to examine patterns of genetic variation in Canadian marine molluscs, both at the phylum and species level. I built a barcode reference library for nearly 300 species of Canadian marine mollusc. In addition, I investigated patterns of population structure and genetic diversity in two species of planktotrophic bivalve with a Holarctic distribution. The latter part of my project focused on how planktonic larval development, ultimately dispersal potential, and repeated glaciation in Canada have shaped genetic structure in contemporary populations.


The specific project/thesis aims are:

• Build a barcode reference library for Canadian marine molluscs

• Examine patterns of genetic variation across this phylum

• Examine population structure and genetic diversity in two common bivalve species with a Holarctic distribution and planktonic larval phaseLayton 3
