  • Diplosphaera Chodatii Around Payuk Lake, Manitoba
    An investigation of the spatial distribution and inference of dispersal method in the semi-aquatic lichenised green alga Diplosphaera chodatii around Payuk Lake, Manitoba by Jennifer A. Doering A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of MASTER OF SCIENCE Department of Biological Sciences University of Manitoba Winnipeg, Manitoba, Canada Copyright © 2017 by Jennifer A. Doering ABSTRACT The spatial distribution of haplotypes within the lichenised green alga Diplosphaera chodatii was investigated by collecting specimens from the inflows, lake, and outflow of Payuk Lake, Manitoba. Rock scrapings were cultured showing the presence of free-living Di. chodatii and seven additional algal taxa on rocks near the lichen thallus. The Internal Transcribed Spacer of ribosomal DNA (ITS rDNA) and β-actin genes were sequenced for phylogenetic and haplotype network analyses showing similarity to one another, but neither corresponded to geographic location suggesting high levels of gene flow. Haplotype variation was investigated with respect to four landscape hypotheses to infer the mode of dispersal, which supported the Wind (ITS) and Hydrology (β-actin) hypotheses. This is the first study to provide evidence that Di. chodatii is dispersed by wind and water, and free-living Di. chodatii may aid in the potential establishment of the lichen, Dermatocarpon luridum, and other semi-aquatic lichens within this ecosystem. ii ACKNOWLEDGMENTS I would like to thank my advisor, Dr. Michele Piercey-Normore, for her many years of guidance and mentorship throughout this project and the many years spent in her lab. I also thank my committee members, Drs.

  • An Investigation of the Symbiotic Association Between the Sub-Aquatic Fungus Dermatocarpon Luridum Var
    An investigation of the symbiotic association between the sub-aquatic fungus Dermatocarpon luridum var. luridum and its green algal photobiont by Kyle Matthew Fontaine A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE Department of Biological Sciences University of Manitoba Winnipeg, Manitoba, Canada Copyright © 2013 by Kyle Fontaine SPECIAL DEDICATION This thesis is dedicated to my Mother, Karen D. Fontaine (July 1955 – February 2013), who sadly passed away after a lengthy battle with cancer. Mom’s death was untimely, transpiring three weeks before my thesis defense, and three months before graduation. I know Mom would be, and is very proud of my accomplishments. I owe my success to the devotion Mom showed as a parent; she raised me with great patience and love, and was always supportive of my goals. Mom was, and always will be, a positive influence in my life. ii “Consider the Lichen. Lichens are just about the hardiest visible organisms on Earth, but the least ambitious.” ― Bill Bryson iii Acknowledgements There are so many people that have contributed in various ways to this M.Sc. thesis that I need to thank. Firstly, to my wonderful supervisor, Dr. Michele Piercey-Normore, I am extremely thankful for all the encouragement, guidance, and support you have provided, not only during the years spent on this Master of Science degree, but all the years that I have been under your supervision. To Dr. Gordon Robinson, I deeply thank you for all the stimulating conversations over the years, along with the support, guidance and insights you have provided throughout my Master’s program; Dr.

Received: 31 July 2012; in revised form: 11 September 2012 / Accepted: 25 September 2012 / Published: 10 October 2012 Abstract: Members of the genus Dermatocarpon are widespread throughout the Northern Hemisphere along the edge of lakes, rivers and streams, and are subject to abiotic conditions reflecting both aquatic and terrestrial environments. Little is known about the evolutionary relationships within the genus and between continents. Investigation of the photobiont(s) associated with sub-aquatic and terrestrial Dermatocarpon species may reveal habitat requirements of the photobiont and the ability for fungal species to share the same photobiont species under different habitat conditions. The focus of our study was to determine the relationship between Canadian and Austrian Dermatocarpon luridum var. luridum along with three additional sub-aquatic Dermatocarpon species, and to determine the species of photobionts that associate with D.
