Alexander William Evans
Alexander William Evans (May 17, 1868 – December 6, 1959) was a botanist, bryologist, and mycologist that specialized in the flora of Connecticut. Early life Born in Buffalo, New York on May 17, 1868, Evan's family moved to New Haven, Connecticut after the death of his father. After graduation from Hillhouse High School, Evans received his Ph.B. from the Sheffield Scientific School at Yale University in 1890. An excellent student, Evans was among the top of his class. Two years later, Evans earned his M.D. from the Yale School of Medicine. After a two-year internship at the Yale-New Haven Hospital, he went to the University of Berlin to briefly study botany under Leopold Kny. John R. Reeder, Charlotte G. Reeder. 1960.

Ivan Mackenzie Lamb
Elke Mackenzie (11 September 1911 – 18 January 1990), born Ivan Mackenzie Lamb, was a British polar explorer and botanist who specialised in the field of lichenology. Early life Mackenzie was born in Clapham, London, on 11 September 1911. Mackenzie's family moved to Scotland while she was a child, and she was enrolled in the Edinburgh Academy. After her graduation in 1929, she attended Edinburgh University. She earned her B.Sc. with Honors in Botany in 1933. She received a scholarship from the German Academic Exchange Service, and continued doing research in botany at the University of Munich and the University of Würzburg.Llano, G. (1991). I.

John R
John R. (born John Richbourg, August 20, 1910 - February 15, 1986) was an American radio disc jockey who attained fame in the 1950s and 1960s for playing rhythm and blues music on Nashville radio station WLAC. He was also a notable record producer and artist manager. Richbourg was arguably the most popular and charismatic of the four announcers at WLAC who showcased popular African-American music in nightly programs from the late 1940s to the early 1970s. (The other three were Gene Nobles, Herman Grizzard, and Bill "Hoss" Allen.) Later rock music disc jockeys, such as Alan Freed and Wolfman Jack, mimicked Richbourg's practice of using speech that simulated African-American street language of the mid-twentieth century. Richbourg's highly stylized approach to on-air presentation of both music and advertising earned him popularity, but it also created identity confusion. Because Richbourg and fellow disc jockey Allen used African-American speech patterns, many listeners thought that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mason Hale
Mason Ellsworth Hale, Jr. (September 23, 1929 – April 23, 1990) was one of the most prolific lichenologists of the 20th century. Many of his scholarly articles focused on the taxonomy of the family Parmeliaceae. Hale was one of the first lichen experts to incorporate secondary chemistry and technology such as computers and scanning electron microscopy into taxonomic work. Mason Hale published approximately two hundred articles and books on various aspects of lichen biology including taxonomy, anatomy, chemistry, and ecology. Hale also wrote several books aimed at education and increasing accessibility to lichens. Early life and education Mason Hale Jr. grew up on a farm outside of Winsted, Connecticut. He had an affinity towards biology from experiences from living on his family's farm. As an undergraduate, Hale wanted to be a linguist, but was not able to take specialized classes. Instead, he earned an undergraduate degree studying biology at Yale University, where he studied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Yasuhiko Asahina
Yasuhiko Asahina (朝比奈泰彦 ''Asahina Yasuhiko''; April 16, 1881 – June 30, 1975) was a Japanese chemist and lichenologist. Early life During his childhood, Asahina developed an interest in plants. In 1902, he enrolled in the School of Pharmacy at Tokyo Imperial University, from which he graduated in 1905. Asahina stayed at the university to research the chemical principles of Chinese traditional medicine under Junichiro Shimoyama. His first paper on styracitol isolation from ''Styrax obassia'' was published in 1907. In 1909, Asahina travelled to Zurich to study phytochemistry under Richard Willstätter. He continued his research on chlorophyll until 1912, when he moved to Berlin. He spent three months in Germany working in the laboratory of Professor Emil Fischer on a styracitol experiment.Shibata, S. (2000).

Cladonia
''Cladonia'' is a genus of moss-like lichens in the family Cladoniaceae. They are the primary food source for reindeer/caribou. ''Cladonia'' species are of economic importance to reindeer-herders, such as the Sami in Scandinavia or the Nenets in Russia. Antibiotic compounds are extracted from some species to create antibiotic cream. The light green species ''Cladonia stellaris'' is used in flower decorations. Although the phylogeny of the genus ''Cladonia'' is still under investigation, two main morphological groups are commonly differentiated by taxonomists: the ''Cladonia'' morpho-type and the ''Cladina'' morpho-type. The ''Cladonia'' morpho-type has many more species, and is generally described as a group of squamulose (grow from squamules), cup-bearing lichens. The ''Cladina'' morpho-types are often referred to as forage lichens, mat-forming lichens, or reindeer lichens (due to their importance as caribou winter forage). ''Cladonia perforata'' ("perforate cladonia") is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichens
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among hypha, filaments of multiple fungus, fungi species in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches (fruticose); flat leaf-like structures (foliose); grow crust-like, adhering tightly to a surface (substrate) like a thick coat of paint (crustose); have a powder-like appearance (Leprose lichen, leprose); or other growth forms.

Hepaticae
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly dif ...

Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

British Bryological Society
The British Bryological Society is an academic society dedicated to bryology, which encourages the study of bryophytes (mosses, liverworts and hornworts). It publishes the peer-reviewed ''Journal of Bryology''. History The Society developed from the Moss Exchange Club founded in 1896 by Coslett Herbert Waddell who was Secretary of the club until 1903. It was therefore the first bryological society in the world. Its aim was to provide communication between those interested in bryophytes so they could build up collections of correctly identified specimens. The Club produced printed reports and compiled records of bryophyte distributions by vice-county, and members exchanged information by letter, but the Club did not hold meetings. Over the years, several updated lists of the moss flora were produced. Members focused on the British Isles, although several were interested in bryophytes of other countries. A proposal for a formal 'Foreign Section' in 1901 was unsuccessful. In 1903 Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
