Irwin M. Brodo (born 1935) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology. [1]
Brodo did his undergraduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. [1] He later went on to teach at Université Laval and the University of Alaska, and he also supervised master's students at the University of Ottawa and Carleton University. [2]
Brodo's list of publications includes 75 research papers, 8 popular articles, 22 reviews and 6 editorials and obituaries. In 1993, Brodie was awarded the Mary E. Elliot Service Award for his meritorious service to the Canadian Botanical Association [3] — and in 2003, for lifetime achievement, the association's George Lawson Medal. [4] One of Irwin Brodo's great achievements was the publication in 2001 of the 795 page book, "Lichens of North America" with high-quality photographs of lichens taken by Sylvia Sharnoff and Stephen Sharnoff. It won the 2002 National Outdoor Book Award (Nature Guidebook). [5] In 2016, the trio, with additional collaborator Susan Laurie-Bourque, produced Keys to Lichens of North America: Revised and Expanded. [6] In 2013, Brodo was presented with an honorary doctorate from Carleton University, "in recognition of his distinguished career in lichenology and scientific leadership in the international biosystematics community". [2]
Several lichen taxa have been named to honour Brodo. These eponyms include:
The Roccellaceae are a family of fungi in the order Arthoniomycetes. Most taxa are lichenized with green algae, although some are lichenicolous, growing on other lichens.
Brodoa is a genus of three species of foliose lichens in the family Parmeliaceae. The genus, circumscribed in 1986 by Trevor Goward, is named in honour of lichenologist Irwin Brodo.
Chicita Frances Culberson is an American lichenologist.
Lepraria is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. Members of the genus are commonly called dust lichens. The main vegetative body (thallus) is made of patches of soredia. There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products are important characters to distinguish between similar species in Lepraria.
Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas.
Aino Marjatta Henssen, was a German lichenologist and systematist. Her father, Gottfried Henssen, was a folklorist and her mother was Finnish.
William Louis "Bill" Culberson was an American lichenologist.
The International Association for Lichenology (IAL) is an organisation that encourages the understanding of lichens and lichenology, and promotes their study and conservation worldwide. It unites lichenologists across the globe, as well as national and regional organisations into one group. It is affiliated to the International Union of Biological Sciences (IUBS). The IAL organises field courses and excursions, as well as symposia which are the biggest events in lichenology on the international level. The 8th International Symposium will be held in Helsinki, Finland, in August 2016.
Ana María Crespo de las Casas is a Spanish lichenologist noted for studying the phytosociology, taxonomy and floristics of Mediterranean lichens. She was awarded the 2012 Acharius Medal from the International Association for Lichenology for lifetime achievements in lichenology, and the genera Crespoa, Cresponea and Cresporhaphis were named in her honor.
Teuvo ("Ted") Tapio Ahti is a Finnish botanist and lichenologist. He has had a long career at the University of Helsinki that started in 1963, and then following his retirement in 1997, at the Botanical Museum of the Finnish Museum of Natural History. Known as a specialist of the lichen family Cladoniaceae, Ahti has published more than 280 scientific publications. A Festschrift was dedicated to him in 1994, and in 2000 he was awarded the prestigious Acharius Medal for lifetime contributions to lichenology.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
John Walter Thomson Jr. (1913–2009) was a Scottish-born American botanist and lichenologist, sometimes referred to as the "Dean of North American Lichens".
Thomas Hawkes Nash III is an American lichenologist. His research is about the biology and ecology of lichens, and the effects of air pollution on plants and lichens. He is known as an authority on the family Parmeliaceae. During his long career at the Arizona State University, he helped develop the lichen herbarium into a world-class collection with over 100,000 specimens representing more than 5000 species. In 2010, the year of his retirement, he was awarded the Acharius Medal for lifetime achievements in lichenology, and the following year had a Festschrift published in his honor.
Leif Tibell is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology.
Gunnar Bror Fritiof Degelius was a Swedish lichenologist. Between the publications of his first and final scientific papers, Degelius had a 70-year-long research career. While he was best known for his expertise on the lichen genus Collema, he also wrote important papers on lichen biology and ecology, floristic studies of the Nordic countries and various other areas around the world, and lichen succession. Degelius described 124 new taxa, and published about 130 scientific papers. In 1992 he was one of the first to be awarded the Acharius Medal for his lifetime contributions to lichenology. Fifteen species and three genera have been named in honour of Degelius.
Rosmarie Honegger is a Swiss lichenologist and Emeritus Professor at the University of Zurich.
Calicium trabinellum, commonly known as the yellow-collar stubble lichen, is a widespread species of pin lichen in the family Caliciaceae. It was first described by Swedish lichenologist Erik Acharius in 1803 as Calicium xylonellum ß trabinellum. He made the new combination Calicium trabinellum in a later chapter of the same publication.
Henricus (Harrie) Johannes Maria Sipman is a Dutch lichenologist. He specialises in tropical and subtropical lichens, and has authored or co-authored more than 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010.
The following outline provides an overview of and topical guide to lichens.
