Echiniscus Testudo
''Echiniscus testudo'' is a cosmopolitan species of tardigrade. Taxonomy The species was described by Louis Michel François Doyère in 1840; he placed it in the genus '' Emydium''. G. Ramazzotti and W. Maucci classified ''E. filamentos mongoliensis'' as a synonym of ''E. testudo'' in 1983; this was followed by other tardigradologists. In 2017, Piotr Gąsiorek and colleagues restored it as a distinct taxon and elevated it to species level: ''E. mongoliensis''. Gąsiorek and colleagues also classified ''E. filamentosus'' and ''E. glaber'' as junior synonyms of ''E. testudo''. Distribution It is found throughout most of the Palaearctic, and has been recorded in all continents except Antarctica and Australia. Most reports are Holarctic. Locations where it has been recorded include: Denmark, Egypt, the Faroe Islands, France, Germany, Greece, Greenland, Israel, Italy, Morocco, Iberia, Mongolia, and China. Doyère based his description off specimens collected in Paris. The neotyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Michel François Doyère
Louis Michel François Doyère (born 28 January 1811 in Saint-Michel-des-Essartiers, Calvados; died 12 July 1863 in Bastia, Corsica) was a French zoologist and agronomist. He was among the first zoologists to study tardigrades, describing species including ''Milnesium tardigradum'' in 1840. Life After obtaining his degree in science, Doyère became a professor in Paris. In 1838, he translated into French the 1836 book ''Geology and Mineralogy considered with reference to Natural Theology'' by William Buckland. Two years later, he published with Dezobry and Magdeleine, a work entitled: ''Lessons in Natural History''. From 1841 to 1842, he was a preparatory assistant at the laboratory of anatomy and natural history of Man, at the French National Museum of Natural History. In 1842, he defended his thesis at the Faculty of Sciences of Paris on the biology of tardigrades, including their ability to survive complete desiccation.

Cosmopolitan Species
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tardigrade
Tardigrades (), known colloquially as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them . In 1776, the Italian biologist Lazzaro Spallanzani named them Tardigrada, which means 'slow walkers'. They live in diverse regions of Earth's biospheremountaintops, the deep sea, tropical rainforests, and the Antarctic. Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other forms of life. Tardigrades have survived exposure to outer space. There are about 1,500 known species in the phylum Tardigrada, a part of the superphylum Ecdysozoa. The earliest known fossil is from the Cambrian, some 500 million years ago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Palaearctic
The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. Both the eastern and westernmost extremes of the Paleartic span into the Western Hemisphere, including Cape Dezhnyov in Chukotka Autonomous Okrug to the east and Iceland to the west. The term was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ Ind ...

Holarctic
The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical region (which covers most of North America), and Alfred Wallace's Palearctic zoogeographical region (which covers North Africa, and all of Eurasia except for Southeast Asia, the Indian subcontinent, the southern Arabian Peninsula). These regions are further subdivided into a variety of ecoregions. Many ecosystems and the animal and plant communities that depend on them extend across a number of continents and cover large portions of the Holarctic realm. This continuity is the result of those regions’ shared glacial history. Major ecosystems Within the Holarctic realm, there are a variety of ecosystems. The type of ecosystem found in a given area depends on its latitude and the local geography. In the far north, a band of Arctic tun ...

Iberia
The Iberian Peninsula ( ), also known as Iberia, is a peninsula in south-western Europe. Mostly separated from the rest of the European landmass by the Pyrenees, it includes the territories of peninsular Spain and Continental Portugal, comprising most of the region, as well as the tiny adjuncts of Andorra, Gibraltar, and, pursuant to the traditional definition of the Pyrenees as the peninsula's northeastern boundary, a small part of France. With an area of approximately , and a population of roughly 53 million, it is the second-largest European peninsula by area, after the Scandinavian Peninsula. Etymology The Iberian Peninsula has always been associated with the River Ebro (Ibēros in ancient Greek and Ibērus or Hibērus in Latin). The association was so well known it was hardly necessary to state; for example, Ibēria was the country "this side of the Ibērus" in Strabo. Pliny goes so far as to assert that the Greeks had called "the whole of the peninsula" Hiberia beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotype
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 ...

Montmartre Cemetery
The Cemetery of Montmartre () is a cemetery in the 18th arrondissement of Paris, France, that dates to the early 19th century. Officially known as the Cimetière du Nord, it is the third largest necropolis in Paris, after the Père Lachaise Cemetery and the Montparnasse Cemetery. History In the mid-18th century, overcrowding in the cemeteries of Paris had created numerous problems, from impossibly high funeral costs to unsanitary living conditions in the surrounding neighborhoods. In the 1780s, the Cimetière des Innocents was officially closed and citizens were banned from burying corpses within the city limits of Paris. During the early 19th century, new cemeteries were constructed outside the precincts of the capital: Montmartre in the north, Père Lachaise Cemetery in the east, Passy Cemetery in the west and Montparnasse Cemetery in the south. The Montmartre Cemetery was opened on 1 January 1825. It was initially known as le Cimetière des Grandes Carrières (Cemetery of the ...

Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...
