Alectoria Ochroleucoides
''Alectoria ochroleucoides'' is a species of fruticose lichen in the family Parmeliaceae. It was formally described as a new species in 2016 by the American lichenologist Theodore Esslinger. The type specimen was collected by Thomas Hawkes Nash III about southeast of Perote, at an elevation of , where it was found growing on soil and rocks. It occurs in alpine areas in the states of Puebla and Veracruz in Mexico, and also in the Andes The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America.

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Cofre De Perote
Cofre de Perote, also known by its Nahuatl names Naupa-Tecutépetl (from ''Nāuhpa-Tēuctēpetl'') and Nauhcampatépetl, both meaning something like "Place of Four Mountains" or "Mountain of the Lord of Four Places", is an inactive volcano located in the Mexican state of Veracruz, at the point where the Trans-Mexican Volcanic Belt, home to all of Mexico's highest peaks, joins the Sierra Madre Oriental. With an elevation of above sea level, Cofre de Perote is Mexico's eighth highest mountain summit. Cofre de Perote is a shield volcano, shaped very differently from the stratovolcanic Pico de Orizaba, which lies about to the southeast. A ''cofre'' is a coffer, and the name alludes to a volcanic outcropping on the shield which constitutes the peak of the mountain. To the north is the town of Perote, Veracruz, after which the mountain is named. The area surrounding the volcano was protected by the Mexican government as a national park A national park is a nature park desi ...

Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but are a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Characteristic of fruticose lichen is the shape of the thallus. Like crustose lichen, fruticose lichen is composed of a holdfast which will act as an anchor for the lichen to grow in rock fissures, over loose sand or soil. Growth and structure Fruticose or ...

Parmeliaceae
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: '' Xanthoparmelia'' ( 822 species), '' Usnea'' (355 species), '' Parmotrema'' ( 255 species), and '' Hypotrachyna'' (262 species). Nearly all members of the family have a symbiotic association with a green alga (most often ''Trebouxia'' spp., but ''Asterochloris'' spp. are known to associate with some species).Miadlikowska, J.

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Thomas Hawkes Nash III
Thomas Hawkes Nash III (born November 13, 1945) is an American lichenologist. His research is about the biology and ecology of lichens, and the effects of air pollution on plants and lichens. He is known as an authority on the family Parmeliaceae. During his long career at the Arizona State University, he helped develop the lichen herbarium into a world-class collection with over 100,000 specimens representing more than 5000 species. In 2010, the year of his retirement, he was awarded the Acharius Medal for lifetime achievements in lichenology, and the following year had a ''Festschrift'' published in his honor. Biography Nash was born in Arlington, Virginia, in 1945. He received a B.Sc. from Duke University in 1967. It was around this time that he was introduced to lichens by ecologist Larry Bliss; he would later take an advanced undergraduate class on lichens given by William Culberson, and a lichenology summer course given by Mason Hale. Nash later went on to earn an M.Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Climate
Alpine climate is the typical climate for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ice cap cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puebla
Puebla, officially the Free and Sovereign State of Puebla, is one of the 31 states that, along with Mexico City, comprise the Federal Entities of Mexico. It is divided into 217 municipalities and its capital is Puebla City. Part of east-central Mexico, it is bordered by the states of Veracruz to the north and east, Hidalgo, México, Tlaxcala and Morelos to the west, and Guerrero and Oaxaca to the south. The origins of the state lie in the city of Puebla, which was founded by the Spanish in this valley in 1531 to secure the trade route between Mexico City and the port of Veracruz. By the end of the 18th century, the area had become a colonial province with its own governor, which would become the State of Puebla, after the Mexican War of Independence in the early 19th century. Since that time the area, especially around the capital city, has continued to grow economically, mostly through industry, despite being the scene of a number of battles, the most notable of which bei ...
