Alan Orange
Alan Orange (19 June 1955 – 5 February 2023) was a British lichenologist. His research interests included lichen taxonomy and phylogenetics, aquatic lichens, and the family Verrucariaceae. Early life and education Alan Orange was born in Leeds on 19 June 1955, and shortly after, his family relocated to Longhope in the Forest of Dean. This environment fostered his passion for botanical exploration, often accompanied by cousins and the family dogs. His penchant for collecting and classifying challenging organisms began in childhood, evident from his extensive bramble collection. Additionally, he showcased a natural talent for art, crafting intricate botanical illustrations throughout his life. Pursuing his passion academically, he completed his undergraduate studies at Bristol University, followed by a master's degree in pure and applied plant taxonomy at Reading University, earning it with distinction. Career and contributions In the early 1980s, Orange worked as a fie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenology
Lichenology is the branch of mycology that studies the lichens, symbiotic organisms made up of an intimate symbiotic association of a microscopic alga (or a cyanobacterium) with a filamentous fungus. Study of lichens draws knowledge from several disciplines: mycology, phycology, microbiology and botany. Scholars of lichenology are known as lichenologists. History The beginnings Lichens as a group have received less attention in classical treatises on botany than other groups although the relationship between humans and some species has been documented from early times. Several species have appeared in the works of Dioscorides, Pliny the Elder and Theophrastus although the studies are not very deep. During the first centuries of the modern age they were usually put forward as examples of spontaneous generation and their reproductive mechanisms were totally ignored. For centuries naturalists had included lichens in diverse groups until in the early 18th century a French researche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

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 also of relevance to lichens worldwide. It has been a registered charity (number 228850) since 1964. History 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. Several positions were decided: Arthur Edward Wade was elected as the secretary, Peter Wilfred James as the editor and recorder, Joseph Peterken as the treasurer, David Smith the librarian, and Swinscow as curator and assistant editor. Another founder was Ursula Katherine Duncan. A tenth-anniversary symposium, held jointly with the British Mycological Society, was held on 27 September 1968. In 1983, the BLS held its silver jubilee celebrations to commemorate 25 years since its founding. A one-day lichenology symposium was held at the Natural Histo ...

Trapeliaceae
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 species. Taxonomy Trapeliaceae was originally circumscribed by French lichenologist Maurice Choisy in 1929. Hannes Hertel emended the family in 1970. Because of similarities in ascus structure, the family was originally classified in the Agyriineae, a suborder of the Lecanorales. Preliminary molecular phylogenetic studies showed that Agyriineae was not related to the Lecanorales, and the order Agyriales was resurrected to contain the family. Some authorities considered Trapeliaceae to be synonymous with Agyriaceae. In 2007, Thorsten Lumbsch and colleagues transferred Trapeliaceae to the order Baeomycetales based on a sister relationship between Trapeliaceae and a clade in the Baeomycetales. This placement contradicted the results of some previous phylogenetic analyses that showed the Trapeliaceae as neither sister nor contained within the Baeomycetales. In 2011, Bren ...

Porinaceae
Trichotheliaceae is a family of lichen-forming fungi in the order Gyalectales. The family was circumscribed by Friedrich von Schilling and Friedrich August Georg Bitter in 1927. In a recent (2018) molecular phylogenetic analysis, Trichotheliaceae was shown to be part of a monophyletic clade containing the families Coenogoniaceae, Gyalectaceae, Phlyctidaceae, and Sagiolechiaceae. Genera According to a recent (2022) survey of fungal classification, Trichotheliaceae contains eight genera and about 365 species. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *''Clathroporina'' – ca. 25 *'' Flabelloporina'' – 1 sp. *'' Myeloconis'' – 4 spp. *''Porina'' – ca. 145 spp. *''Pseudosagedia'' – 80 spp. *'' Saxiloba'' – 2 spp. *'' Segestria'' – 70 spp. *''Trichothelium ''Trichothelium'' is a genus of lichen-forming fungi in the family Trichotheliaceae.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Crustose Lichen
Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cortex (botany), cortex layer, an algal layer, and a medulla. The upper cortex layer is differentiated and is usually pigmented. The algal layer lies beneath the cortex. The medulla fastens the lichen to the substrate and is made up of Fungus, fungal hyphae. The surface of crustose lichens is characterized by branching cracks that periodically close in response to climatic variations such as alternate wetting and drying regimes. Subtypes * Powdery – considered as the simplest subtype due to the absence of an organized thallus. :The thallus appears powdery. :E.g. Genera ''Lepraria'', ''Vezdaea'' * Endolithic – grows inside the rock, usually in interstitial spaces between mineral grains. The :upper cortex is usually d ...

Research Fellow
A research fellow is an academic research position at a university or a similar research institution, usually for academic staff or faculty members. A research fellow may act either as an independent investigator or under the supervision of a principal investigator. Although research fellow positions vary in different countries and academic institutions, it is in general that they are junior researchers who try to develop their research careers under the guidance of senior researchers. United Kingdom In many universities this position is a career grade of a ''Research Career Pathway'', following on from a postdoctoral position such as research associate, and may be open-ended, subject to normal probation regulations. Within such a path, the next two higher career grades are usually senior research fellow and professorial fellow. Although similar to the position of a research fellow, these two positions are research only posts, with the rise of the career grade there will normal ...

Curator
A curator (from la, cura, meaning "to take care") is a manager or overseer. When working with cultural organizations, a curator is typically a "collections curator" or an "exhibitions curator", and has multifaceted tasks dependent on the particular institution and its mission. In recent years the role of curator has evolved alongside the changing role of museums, and the term "curator" may designate the head of any given division. More recently, new kinds of curators have started to emerge: "community curators", "literary curators", " digital curators" and " biocurators". Collections curator A "collections curator", a "museum curator" or a "keeper" of a cultural heritage institution (e.g., gallery, museum, library or archive) is a content specialist charged with an institution's collections and involved with the interpretation of heritage material including historical artifacts. A collections curator's concern necessarily involves tangible objects of some sort—artwork, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lady Park Wood National Nature Reserve
Lady Park Wood National Nature Reserve () is a nature reserve straddling the borders of Gloucestershire in England and Monmouthshire in Wales. Most of the wood is in Wales – where it forms Wales' easternmost point – but it is managed under agreement with Natural England. The wood is in the Wye Valley Area of Outstanding Natural Beauty. It is part of the Upper Wye Gorge Site of Special Scientific Interest (SSSI) and the River Wye Special Area of Conservation (SAC). The site is owned by the Forestry Commission and access is on recognised rights of way. Permits are needed to access non-public areas. The wood has been a research location for some time as unmanaged woodland and is a prime woodland conservation area. It is notable as being the easternmost point of Wales. The wood take its name from the estate to which it formerly belonged, which was built up chiefly between about 1580 and 1650 by the Hall family of the now demolished High Meadow House. The woods were inhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
