Lecidea Aptrootii
''Lecidea aptrootii'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecideaceae. It is found in northwestern Pakistan, where it grows on exposed siliceous rocks. The lichen was formally described as a new species in 2018 by Memoona Khan, Abdul Khalid, and H. Thorsten Lumbsch. The type specimen was collected in the Gabin Jabba valley (Swat District, Khyber Pakhtunkhwa) at an altitude of . This area has a moist temperate climate, with snowfall during winter and much rainfall during summer. The species epithet honours Dutch lichenologist André Aptroot, who suggested to the authors that the taxon In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Helge Thorsten Lumbsch
Helge Thorsten Lumbsch (born 1964) is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History. Biography Lumbsch was born in Frankfurt in 1964. Interested in lichens already as a schoolboy, he studied natural sciences at the University of Marburg, under the tutelage of Aino Henssen. He received his diploma in 1989, with a dissertation titled ''Ontogenetisch-systematische Studien der Trapeliaceae und verwandter Familien (Lichenisierte Ascomyceten)'' ("Ontogenic-systematic studies of the Trapeliaceae and related families (lichenized ascomycetes"). After Henssen's retirement in 1990, he transferred to the University in Essen, where he worked on the ''Lecanora subfusca'' group in Australasia, a subje ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Taxon
In biology, a taxon ( back-formation from '' taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
André Aptroot
André Aptroot ( Heemskerk, 1961) is a Dutch mycologist and lichenologist. In 1993 he did his PhD at the University of Utrecht under the supervision of Robbert Gradstein (nl). His dissertation was titled "Systematic studies on pyrenocarpous lichens and related fungi". He specializes in fungi and lichens on which he has several hundreds of publications to his name.

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] |

Saxicolous Lichen
A saxicolous lichen is a lichen that grows on rock. The prefix "sax" from the Latin means "rock" or "stone". Characteristics Saxicolous lichens exhibit very slow growth rates. They may develop on rock substrates for long periods of time, given the absence of external disturbances. The importance of the mineral composition of the rock substrate, as well as the elemental geochemistry Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the ... is also important to the distribution of saxicolous lichens, but the relationship between the substrate influence on lichens, either chemical or textural, is still obscure.

Swat District
Swat District (, ps, سوات ولسوالۍ, ) is a district in the Malakand Division of Khyber Pakhtunkhwa, Pakistan. With a population of 2,309,570 per the 2017 national census, Swat is the 15th-largest district of Khyber Pakhtunkhwa province. Swat District is centered on the Valley of Swat, usually referred to simply as Swat, which is a natural geographic region surrounding the Swat River. The valley was a major centre of early Buddhism under the ancient kingdom of Gandhara, and was a major centre of Gandharan Buddhism, with pockets of Buddhism persisting in the valley until the 10th century, after which the area became largely Muslim. Until 1969, Swat was part of the Yusafzai State of Swat, a self-governing princely state that was inherited by Pakistan following its independence from British rule. The region was seized by the Tehrik-i-Taliban in late-2007 until Pakistani control was re-established in mid-2009. The average elevation of Swat is , resulting in a co ...
