Title: Diversity in a Minnow Trap: Evolution of the Endemic Nova Scotian White Stickleback and Asexual Killifish Clones
Speaker: Dr. Anne Dalziel
Department of Biology, Saint Mary’s University
The species of sticklebacks and killifishes living along the Nova Scotian shore have evolved great diversity in physiology and behaviour among populations and species
Studying these small fish can help biologists better understand how aquatic species can adapt to changes in their environment.
Dr. Dalziel will discuss current research on the breeding biology of an endemic Nova Scotian species of stickleback, the ‘white stickleback’, a fish that has evolved unique male breeding colors and behaviour. She will also present research on the evolution of salinity tolerance and breeding behaviour among species of killifishes, including asexual hybrids.
