Monocalenia
''Monocalenia'' is a fungal genus in the family Gomphillaceae. It comprises the single species ''Monocalenia monospora'', a leaf-dwelling lichen that occurs in Guinea and the Galápagos Islands. Taxonomy Genus ''Monocalenia'' contains a single species, ''Monocalenia monospora'', which was originally described as ''Calenia monospora'' by the Czech lichenologist Antonín Vězda in 1979. The species was later transferred to its own genus by Amanda Xavier-Leite, Marcela Cáceres, and Robert Lücking in 2023 based on molecular phylogenetics analysis that showed it was unrelated to '' Calenia'' in the strict sense and instead allied with ''Asterothyrium''. The genus is of several segregates from the historically broad concept of ''Calenia'' that were recognised following modern molecular systematic studies of the Gomphillaceae. The genus name combines "Calenia" (the original genus) with a reference to the distinctive single-spored asci that characterise the species. ''Monocalenia' ...

Gomphillaceae
The Gomphillaceae are a family of lichen-forming fungi in the order Graphidales. Species in this family are found mostly in tropical regions. The family underwent a major molecular phylogenetics-led reorganisation in 2023, in which 17 genera were recognised and formally established as new or reinstated. Taxonomy The Gomphillaceae has undergone significant taxonomic revision as molecular analysis techniques have improved scientists' understanding of relationships between species. As of 2024, the family includes approximately 440 accepted species, of which 422 are lichenised (form a symbiotic relationship with algae) and 18 are lichenicolous or fungicolous (grow on other lichens or fungi). The family is particularly diverse in tropical regions, where many species grow on leaves in wet forests. However, some members, particularly in the genus '' Gyalideopsis'', can also be found growing on other surfaces and extend into temperate regions. Recent molecular phylogenetics studies (an ...

Robert Lücking
Robert Lücking (born 1964) is a German lichenologist, known for his extensive research on foliicolous lichens (lichens that live on leaves) and his significant contributions to the taxonomy, ecology, and biodiversity of fungi and lichens. He earned his master's and PhD from the University of Ulm, focusing on foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale Award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in the scientific journal '' The Bryologist''. Since 2015, Lücking has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, overseeing a vast scientific collection and contributing to major advancements in molecular phylogenetics in lichenology. Lücking has authored or co-authored the description of more than 1000 taxa, making him one of the most prolific modern lichenologists. ...

Septum
In biology, a septum (Latin language, Latin for ''something that encloses''; septa) is a wall, dividing a Body cavity, cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the Pulmonary alveolus, alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Septum of the penis, Penile septum, a fibrous w ...

Taxa Described In 2023
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 still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichen Genera
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphidales Genera
Graphidales is an order (biology), order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 family (biology), families, about 81 genus, genera and about 2,228 species. Family Graphidaceae are the largest crustose family within Graphidales order comprising more than 2000 species, which are widely distributed in tropical and subtropical regions of the world. History The Graphidales were introduced in a 1884 publication by Frigyes Ákos Hazslinszky in Magyar Birodalom Zuzmó-Flórája on page 216 as family Graphideae. In 1907, they were established as an Order (biology), order by American botanist Charles Edwin Bessey, Bessey (1845–1915), When the order was introduced, it contained just two families, the Graphidaceae and Thelotremataceae who were both mainly tropical based and each family had about 800–1000 species. Sherwood in 1977 proposed to maintain a distinction between the Graphidales with mostly lichenised members and the Ostropales which included mostl ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...

Montane
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...
