Platygramme Subarechavaletae
''Platygramme subarechavaletae'' is a species of script lichen in the family Graphidaceae. Found in Thailand, it was species description, formally described as a new species in 2014 by lichenologists Vasun Poengsungnoen and Klaus Kalb. The type (biology), type specimen was collected by the first author from the Phu Luang Wildlife Sanctuary (Loei) at an elevation of , there it was found growing on an unidentified tree in a lower montane Deserts and xeric shrublands, scrub. The lichen has a grey to yellowish-green thallus with a smooth and dull surface. The botanical name, species epithet alludes to its resemblance to ''Platygramme arechavaletae''.

Klaus Kalb
Klaus Kalb (born 1942) is a German lichenologist and an authority on tropical lichens. Biography Klaus Kalb was born in Nuremberg in 1942 and grew up in southern Bavaria. From 1960 to 1965 he studied biology, chemistry, and geography at the University of Erlangen–Nuremberg. Kalb was greatly interested in lichens and decided to pursue a doctoral degree; his thesis work was about lichen communities in the Ötztal Alps. From 1978–1981 he was a teacher at the Colégio Visconde de Porto Seguro in São Paulo, Brazil. This position afforded him the opportunity to initiate research into tropical lichens. Kalb earned his habilitation from the University of Regensburg in 1989, becoming an associate professor with that institution. In 2014, the University of Wisconsin herbarium purchased Kalb's lichen collection of 60,000 specimens for $75,000. With the acquisition of Kalb's collection, rich in tropical and European specimens, the herbarium houses about 70% of the world's ...

Script Lichen
A script lichen, or graphid lichen, is a member of a group of lichens which have spore producing structures that look like writing on the lichen body. The structures are elongated and narrow apothecia called lirellae, which look like short scribbles on the thallus. "Graphid" is derived from Greek for "writing". An example is ''Graphis mucronata ''Graphis mucronata ''is a graphid lichen found in Australia. It is in the family Graphidaceae The Graphidaceae are a family of lichens in the order Ostropales.

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] |
Type (biology)
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. 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 (mathematics), 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 ...

Phu Luang Wildlife Sanctuary
Phu Luang Wildlife Sanctuary ( th, เขตรักษาพันธุ์สัตว์ป่าภูหลวง) is a wildlife sanctuary in northern Thailand, located in the Phu Luang mountain area, in the south of Loei Province. The area around the mountain is part of the Luang Prabang montane rain forests ecoregion. It covers an area of 897 km², covering area of the ''tambon'' Pla Ba and Tha Sala of Phu Ruea District, Phon Sung, Wang Yao and I Pum of Dan Sai, Nong Ngio and Saikhao of Wang Saphung, and Phu Ho of Phu Luang District. History The wildlife reserve was established in 1974. In 1985 it was further enlarged by 97 km². The reserve is named after its highest mountain, which peaks at 1,571 m. The reserve covers the whole mountain plateau around the peak, which has an elevation of around 1,200 m. To west of the reserve the Loei River originates. "Phu Luang" means "large mountain" or the "mountain of the king", formed by an uplift of the earth's crus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi, become quite cold in winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.

Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or " twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts ( leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoid ...

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the '' International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name '' Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
