Rolf Santesson
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology. Early life and education Santesson was born in 1916 in Trollhättan, Sweden. He was already collecting lichens as a student, investigating the lichen flora of the table mountains of Halleberg and Hunneberg near his home. He entered the University of Uppsala in the 1930s to study botany. It was here he met the flamboyant Professor of Plant Ecology and lichen taxonomist Gustaf Einar Du Rietz, with whom he undertook studies on crustose lichens found on shoreline rocks of Swedish lakes. This work led to a lifelong interest in marine lichens. He earned a B.Sc. in 1938, followed by an M.Sc. in 1939. That same year, joined by zoologist Christian Olrog, Santesson embarked on what was supposed to be an eight-month research excursion in Patagonia (southern South America). Because of the outbreak of war, which made sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trollhättan
Trollhättan () is the 23rd-largest city in Sweden, the seat of Trollhättan Municipality, Västra Götaland County. It is situated by Göta älv, near the lake Vänern, and has a population of approximately 50,000 in the city proper. It is located 75 km (46 mi) north of Sweden's second-largest city, Gothenburg. History Trollhättan was granted city rights (which today have no legal effect) in 1916 at which time it had about 15,000 inhabitants, now grown to 59,058. Trollhättan was founded on the river Göta älv, at the Trollhättan Falls. The site was first mentioned in literature from 1413. Trollhättan had a strategic significance on the road between Västergötland and Norway. It was also of a commercial and political significance for shipping to and from Vänern. Utilization of the river falls was the first important business activity in the area. From the Middle Ages milling and sawing operations have been conducted where the city center is now located.

Menegazzia
''Menegazzia'' is a genus of lichenized fungi containing roughly 70 accepted species.Galloway, D.J. (2007). Flora of New Zealand - ''Menegazzia'' http://floraseries.landcareresearch.co.nz/pages/index.aspx The group is sometimes referred to as the tree flutes, honeycombed lichens, or hole-punch lichens. The most obvious morphological feature of the genus is the distinctive perforations spread across the upper side of the thallus. This makes the group easy to recognise, even for those not particularly familiar with lichen identification. The genus has a sub-cosmopolitan distribution (excluding Antarctica), but is concentrated in Australasia, Melanesia, and southern South America. Most species grow exclusively on trees, but some grow on rocks, moss, and/or soil. Etymology ''Menegazzia'' was described by the Veronese lichenologist Abramo Massalongo in 1854.James, P.W. and Galloway, D.J. (1992).

Robert Lücking
Robert Lücking (born 1964) is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves. Life and career Born in Ulm in 1964, Lücking earned both his master's (1990) and PhD degree (1994) at the University of Ulm. Both degrees concerned the taxonomy, ecology, and biodiversity of foliicolous lichens. His graduate supervisor was mycologist and bryologist Sieghard Winkler, who had previously studied epiphyllous (upper leaf-dwelling) fungi in El Salvador and Colombia. In 1996 Lücking was awarded the Mason E. Hale award for an "outstanding doctoral thesis presented by a candidate on a lichenological theme". His thesis was titled ''Foliikole Flechten und ihre Mikrohabitatpraferenzen in einem tropischen Regenwald in Costa Rica'' ("Foliicolous lichens and their microhabitat preferences in a tropical rainforest in Costa Rica"). In this work, Lücking recorded 177 foliicolous lichen species from the shrub layer in a Costa Rican tropical forest. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichenicolous Fungi
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul. The Bryologist 106(1), pp. 80 120, 2003/ref> More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 classes and 19 orders. Although basidiomycetes have less than 5% of lichenicolous lichen species, they represent 4 classes and 8 orders. Many lichenicolous species have yet to be assigned a phylogenetic position as of 2003. See also * List of lichenicolous fungi o ...

University Of Uppsala Botanical Garden
The University of Uppsala Botanical Garden (in Swedish ''Botaniska trädgården''), near Uppsala Castle, is the principal botanical garden belonging to Uppsala University. It was created on land donated to the university in 1787 by Sweden's King Gustav III, who also laid the cornerstone of ''Linneanum'', its orangery. Uppsala University also maintains two satellite botanical gardens. The older of these is its original botanical garden, created in 1655 by Olaus Rudbeck, now called the Linnaean Garden (in Swedish ''Linnéträdgården''). The other satellite is Linnaeus Hammarby (''Linnés Hammarby''), the former summer home of Carl Linnaeus and his family. The first botanical garden in Uppsala Early botanical gardens focused on educating and supplying physicians, as had the medicinal gardens of medieval monasteries. Medical training remained the primary purpose of university botanical gardens throughout the seventeenth and eighteenth centuries. In 1655, Uppsala University's Ol ...

Foliicolous Lichen
A foliicolous lichenized fungi is a lichen which grows on the surfaces of living leaves of vascular plants, usually inhabiting the upper surface (epiphyllous) but sometimes also the lower surface (hypophyllous). Foliicolous lichens largely occur in tropical environments and of the over 800 foliicolous lichens accepted (as of 2008) over 600 of these are known from the tropics. Unlike most lichens which are common in humid but cool and temperate climates, these tropical lichens are more suited to the higher temperatures and lower light levels present beneath the rainforest canopy, where they are involved in the nutrient cycle and water retention. Chlorophyta are common photosynthetic Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in c ... partner phycobionts of epiphyllous lichens. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctoral Dissertation
A thesis ( : theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.International Standard ISO 7144: DocumentationâPresentation of theses and similar documents International Organization for Standardization, Geneva, 1986. In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate. This is the typical arrangement in American English. In other contexts, such as within most institutions of the United Kingdom and Republic of Ireland, the reverse is true. The term graduate thesis is sometimes used to refer to both master's theses and doctoral dissertations. The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, and the required minimum study period may thus vary significantly in du ...

Swedish Museum Of Natural History
The Swedish Museum of Natural History ( sv, Naturhistoriska riksmuseet, literally, the National Museum of Natural History), in Stockholm, is one of two major museums of natural history in Sweden, the other one being located in Gothenburg. The museum was founded in 1819 by the Royal Swedish Academy of Sciences, but goes back to the collections acquired mostly through donations by the academy since its foundation in 1739. These collections had first been made available to the public in 1786. The museum was separated from the Academy in 1965. One of the keepers of the collections of the academy during its earlier history was Anders Sparrman, a student of Carl Linnaeus and participant in the voyages of Captain James Cook. Another important name in the history of the museum is the zoologist, paleontologist and archaeologist Sven Nilsson, who brought the previously disorganised zoological collections of the museum into order during his time as keeper (1828–1831) before returning t ...

Calicioid Lichen
Lichens are composite organisms made up of multiple species: a fungal partner, one or more photosynthetic partners, and sometimes a basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known as the cortex, may be found o ...
