Bio/Research

Dr. Lynn began his career as an undergraduate student majoring in Honours Marine Biology at the University of Guelph. He was interested and inspired to study ciliates by the late Dr. Jacques Berger, University of Toronto, with whom he studied the endosymbiotic ciliates in the intestines of sea urchins. In this early work, he redescribed the large philasterine carnivores, Plagiopyliella and Thyrophylax, using protargol staining. Dr. Lynn’s doctoral research examined the variations in cortical ultrastructure and kinetids of colpodean ciliates. This work lead to his proposal of the structural conservatism hypothesis, which argued that the cortical ultrastructural components were more highly conserved than “higher order” structures and that these cortical structures should provide a stronger phylogenetic signal for relationships. Applying this principle, Dr. Lynn and Dr. Eugene B. Small, University of Maryland, proposed a revised ciliate macrosystem, which recognized a number of new classes of ciliates based primarily on the ultrastructure of the microtubules associated with somatic basal bodies or kinetosomes. Since the mid-1980’s, Dr. Lynn’s laboratory has been testing this proposed macrosystem using the sequences of the small subunit rRNA gene. Dr. Lynn and his students have also published research on the ecology of marine, freshwater, and terrestrial ciliates and have described a number of new species using their quantitative protargol staining procedure. Dr. Lynn is currently Editor-in-Chief of The Journal of Eukaryotic Microbiology.
