Per Magnus Jørgensen
Per Magnus Jørgensen (born 1944) is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen. He is known for his work on the lichen families Pannariaceae and Collemataceae. Jørgensen was awarded the Acharius Medal in 2021 for his lifetime contributions to lichenology. Biography Jørgensen was born in Stavanger, Norway, in 1944. He obtained his Candidatus realium from the University of Bergen in 1969, where Knut Fægri was his supervisor. In 1978, he earned a doctor philosophiae from University of Bergen, with a dissertation titled "The lichen family Pannariaceae in Europe". He was a student of prominent lichenologist Rolf Santesson; Gunnar Degelius was another early mentor. During his time as a student, he was recruited to work at the Botanical Garden in Bergen. A few years after receiving his doctorate, he was appointed Professor of Systematic Botany at the University of Bergen in 1982. He was known for delivering hi ...

Stavanger
Stavanger, officially the Stavanger Municipality, is a city and municipalities of Norway, municipality in Norway. It is the third largest city and third largest metropolitan area in Norway (through conurbation with neighboring Sandnes) and the administrative center of Rogaland county. The municipality is the fourth most populous in Norway. Located on the Stavanger Peninsula in southwest Norway, Stavanger counts its official founding year as 1125, the year the Stavanger Cathedral was completed. Stavanger's core is to a large degree 18th- and 19th-century wooden houses that are protected and considered part of the city's cultural heritage. This has caused the town center and inner city to retain a small-town character with an unusually high ratio of detached houses, and has contributed significantly to spreading the city's population growth to outlying parts of Greater Stavanger. The city's population rapidly grew in the late 20th century due to its oil industry. Stavanger is know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematics
Systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships, graphically represented in cladograms) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms ( biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word of Ancient Greek origin '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different br ...

Stigmidium Joergensenii
''Stigmidium'' is a genus of lichenicolous (lichen-eating) fungi in the family Mycosphaerellaceae. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1860, with '' Stigmidium schaereri'' assigned as the type species.

British Lichen Society
The British Lichen Society (BLS) was founded in 1958 with the objective of promoting the study and conservation of lichen. Although the society was founded in London, UK, it is of relevance to lichens worldwide. It has been a registered charity (number 228850) since 1964. History Prior to the Society's formation, discussions were held with both the British Bryological Society and the British Mycological Society about potentially establishing a lichen section within one of these existing organisations. However, these talks were unsuccessful; the British Mycological Society offered lichenologists only two pages at the end of their journal, while a joint meeting with bryologists revealed that productive sites for lichens rarely coincided with those favoured by bryologists. At the instigation of Dougal Swinscow, the first meeting of the society was held at the British Museum on 1 February 1958; there were 24 attendees. Twenty-five people attended this inaugural meeting and almo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naturen
''Naturen'' () is a Norwegian popular science magazine, which has been published since 1877 in Bergen, Norway. It is the earliest still running popular science magazine of the country. History and profile ''Naturen'' was started by the geologist Hans Reusch in Bergen in 1877. It was subtitled ''Et illustreret Maanedsskrift for popular Naturvidenskab'' (An Illustrated Monthly for Popular Natural Sciences). It is connected to the University of Bergen. It has a popular science approach to the natural sciences, including medicine. ''Naturen'' was edited by its founder, Hans Reusch, for the first four years. Among its former editors are Jens Holmboe (1906–1925), Torbjørn Gaarder (1925–1946) and Knut Fægri (1947–1977), and Per Magnus Jørgensen Per Magnus Jørgensen (born 1944) is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen.

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Johan Ernst Gunnerus (26 February 1718 – 25 September 1773) was a Norway, Norwegian bishop and botanist. Gunnerus was born at Oslo, Christiania. He was bishop of the Diocese of Nidaros from 1758 until his death and also a professor of theology at the University of Copenhagen. Biography Gunnerus was born and raised in Oslo, Christiania in Norway. He enrolled at the University of Copenhagen in Denmark in 1737, but had to postpone his studies for three years because of poverty. He studied in Copenhagen from 1740, at Martin Luther University of Halle-Wittenberg, Halle in Germany from 1742, and at Friedrich-Schiller-Universität Jena, Jena from 1744, where he received his Magister degree in 1745 and in 1753 was admitted to the Faculty of Philosophy.

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
