Leif Randulff Ryvarden (born 9 August 1935) is a Norwegian mycologist.
Leif Ryvarden was born in Bergen as a son of Einar Norberg Johansen (1900–1959) and Hjørdis Randulff (1912–1975). [2]
He finished his secondary education at Berg in 1954 and took basic military education from 1957 to 1958 and in 1956 he changed his last name from Johansen to Ryvarden. He studied chemistry at the Norwegian Institute of Technology. [2] In 1961 he ran for election as chairman of Student Society in Trondheim, albeit unsuccessfully. [3] In 1963, he graduated with the siv.ing. degree , [2] and later majored in botany at the University of Oslo, taking a cand.real. degree. He also studied in London from 1971 to 1972, a stay that sparked his interest in mycology. [4]
Ryvarden conducted field work in about eighty countries, mostly in a tropical environment. [5] From 1965 to 1966, he was employed as research assistant at the Norwegian Institute of Technology, from 1966 to 1972 as a research fellow at the University of Oslo and then associate professor. He was promoted to professor at the University of Oslo in 1992, and served until 2002. [2] [6] He is currently a professor emeritus. By 2012, Ryvarden had published more than 300 academic works. [7]
He has chaired the Norwegian Botanical Association. He has been an editorial board member of the journals Neotropica , Plant Systematics and Evolution and Mycological Progress , and a council member of the Research Council of Norway department for sciences. [2]
In 1961 he married teacher Ingbjørg Alise Eia Barstad. [2]
Ryvarden was also noted for his contributions in popular science, including writing for children. For this, some criticized him for simplifying the subject—Ryvarden replied that one should "not take oneself too solemnly". His main work in the children's category was Norsk naturleksikon for barn, a twelve-volume natural science encyclopedia for children. Other popular works include the 1983 Norges nasjonalparker, describing the national parks of Norway, [4] and Norges isbreer, co-published with Bjørn Wold in 1991, about the glaciers of Norway. Together with Per Roger Lauritzen he published Fjellnorge (2001), describing the mountains of Norway, [2] and KystNorge (2006) about coastal Norway. Both works spanned three volumes. Ryvarden also wrote guides on mushrooms, berries, herbs and fauna.
Ryvarden was a member of the board from 1972 to 1985, and deputy leader since 1982, of the Norwegian Mountain Touring Association. [2] He was a prolific writer for the Norwegian Mountain Touring Association Yearbook as well as their magazine Fjell og Vidde . [8] He was also a member of the board of Greenpeace Norway for a year and a half, but resigned from this position in 1992 due to disagreements over the organization's strategy and priorities. Ryvarden especially criticized their perceived bias towards saving an amount of minke whale. He cited that all species are equally important, and also reminded that there were other pressing environmental issues in Norway at that time. As Ryvarden left, there were no longer any Norwegian citizens on the board of Greenpeace Norway. [9] Later, Ryvarden publicly supported Bjørn Økern, who was fired as leader of Greenpeace Norway in 1992. [10]
Ryvarden is a member of the Norwegian Academy of Science and Letters. [11] Ryvarden holds an honorary degree at the University of Gothenburg, and since 2008 the National University of Córdoba. [12] He is also an honorary member of the Mycological Society of America.
He won the Brage Prize in 1998 in the category non-fiction, for the book Er det liv, er det sopp which he co-wrote with Klaus Høiland. [6] In 2002 he was given the University of Oslo Research Promotion Award. [4] In 2007, Ryvarden and Lauritzen were awarded the Norwegian Outdoors Prize for their books. [13] He has also received a prize from the Ministry of the Environment. [8] A special issue of the scientific journal Kurtziana was dedicated to Ryvarden "in honour of his devotion to South American mycology". [7] Fungal taxa named in his honour include the polypore genera Leifiporia [14] and Ryvardenia , [15] and the species Daedalea ryvardeniana . [16]
Polyporus is a genus of poroid fungi in the family Polyporaceae.
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft to very tough. Most members of this family have their hymenium in vertical pores on the underside of the caps, but some of them have gills or gill-like structures. Many species are brackets, but others have a definite stipe – for example, Polyporus badius.
Nils Christian Stenseth is a Norwegian biologist with a focus on ecology and evolution. He is the director of the Centre for Ecological and Evolutionary Synthesis (CEES) at the University of Oslo, CEES was given Centre of Excellence status by the Research Council of Norway in December 2006. He is also the Chief Scientist at the Norwegian Institute of Marine Research in Norway, and Honorary Professor of Tsinghua University.
Oxyporus is a genus of polypore fungi in the family Schizoporaceae. An individual family Oxyporaceae was described for the genus. A number of species in this genus are plant pathogens, causing a white rot. The genus is widely distributed.
Daedalea is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1801 by mycologist Christian Hendrik Persoon, based on the type D. quercina and four other species. The generic name is derived from the Ancient Greek δαιδαλεος.
Arnved Nedkvitne is a Norwegian historian of the Middle Ages and Professor Emeritus of mediaeval history. He held the chair of Norwegian mediaeval history at the University of Trondheim from 1991 to 1993 and at the University of Oslo from 1993 to 2009. He is a member of the Royal Norwegian Society of Sciences and Letters, and was elected in 1993. Nedkvitne is regarded as "one of Norway's preeminent commercial historians" and as Norway's foremost mediaeval historian. His research has focused on Norwegian urban history, foreign trade, the economy of coastal communities and pre-modern social organisation. He is the foremost scholar of the relations between the Hanseatic League and Norway; his research has also explored topics such as honour, law and religious ethics in Scandinavia, the social consequences of literacy in the Middle Ages, lay beliefs of mediaeval Scandinavia, and the Norse settlement of Arctic Greenland.
In 1910 Haakon VII serves his sixth year as King of Norway. On 1 February Wollert Konow takes over as Prime Minister after Gunnar Knudsen, who has held this position since 1908.
Antrodiella is a genus of fungi in the family Steccherinaceae of the order Polyporales.
Dichomitus is a genus of poroid crust fungi in the family Polyporaceae. It was circumscribed by English mycologist Derek Reid in 1965.
Piloporia is a genus of two species of poroid fungi in the family Polyporaceae. The genus was circumscribed by Finnish mycologist Tuomo Niemelä in 1982, with P. sajanensis as the type species. The Indian species P. indica was added to the genus in 1988. P. sajanensis is found in Asia and Europe. In Asia, it is usually recorded on spruce, fir, and larch, while in Europe it is commonly found on spruce, but also on pine. Piloporia species cause a white rot in conifers and hardwoods.
Pseudopiptoporus is a genus of fungi in the family Polyporaceae. It was circumscribed by Norwegian mycologist Leif Ryvarden in 1980 with the type species Pseudopiptoporus devians. This fungus was originally published as Polyporus devians by Giacomo Bresadola in 1920. Pseudopiptoporus chocolatus was added to the genus in 2003.
Skeletocutis is a genus of about 40 species of poroid fungi in the family Polyporaceae. The genus has a cosmopolitan distribution, although most species are found in the Northern Hemisphere. It causes a white rot in a diverse array of woody substrates, and the fruit bodies grow as a crust on the surface of the decaying wood. Sometimes the edges of the crust are turned outward to form rudimentary bracket-like caps.
