Canis Lupus Subspecies
There are 38 subspecies of ''Canis lupus'' listed in the taxonomic authority ''Mammal Species of the World'' (2005, 3rd edition). These subspecies were named over the past 250 years, and since their naming, a number of them have gone extinct. The nominate subspecies is the Eurasian wolf (''Canis lupus lupus''). Taxonomy In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his ''Systema Naturae'' the binomial nomenclature – or the two-word naming – of species. ''Canis'' is the Latin word meaning "dog", and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as ''Canis familiaris'', and on the next page he classified the wolf as ''Canis lupus''. Linnaeus considered the dog to be a separate species from the wolf because of its head and body and tail ''cauda recurvata'' - its upturning tail - which is not found in any other canid. In 1999, a study of mitochondrial DNA indicated that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an age in the international geologic timescale or a stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.770 Ma (770,000 years ago) and 0.126 Ma (126,000 years ago), also expressed as 770–126 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian and succeeded by the proposed Tarantian. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. It ends with the onset of the Eemian interglacial period (Marine Isotope Stage 5). The term Middle Pleistocene was in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). W ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Himalayan Wolf
The Himalayan wolf (''Canis lupus chanco'') is a canine of debated taxonomy. It is distinguished by its genetic markers, with mitochondrial DNA indicating that it is genetically basal to the Holarctic gray wolf, genetically the same wolf as the Tibetan and Mongolian wolf, and has an association with the African wolf (''Canis lupaster''). No striking morphological differences are seen between the wolves from the Himalayas and those from Tibet. The Himalayan wolf lineage can be found living in Ladakh in the Himalayas, the Tibetan Plateau, and the mountains of Central Asia predominantly above in elevation because it has adapted to a low-oxygen environment, compared with other wolves that are found only at lower elevations. Some authors have proposed the reclassification of this lineage as a separate species. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau. The group ...

Italian Wolf
The Italian wolf (''Canis lupus italicus'' or ''Canis lupus lupus''), also known as the Apennine wolf, is a subspecies of the grey wolf native to the Italian Peninsula. It inhabits the Apennine Mountains and the Western Alps, though it is undergoing expansion towards the north and east. As of 2022 the wolf population within Italy is estimated to be 3,307 individuals. Although not universally recognised as a distinct subspecies, it nonetheless possesses a unique mtDNA haplotype and a distinct skull morphology. It has been strictly protected in Italy since the 1970s, when the population reached a low of 70–100 individuals. The population is increasing in number, though illegal hunting and persecution still constitute a threat. Since the 1990s, the Italian wolf's range has expanded into southeastern France and Switzerland. The Italian wolf features prominently in Latin and Italian cultures, such as in the legend of the founding of Rome. It is unofficially considered the national ...

Arabian Wolf
The Arabian wolf (''Canis lupus arabs'') is a subspecies of gray wolf native to the Arabian Peninsula, the Negev Desert, the Sinai Peninsula, and Jordan. It is the smallest wolf subspecies, and a desert-adapted subspecies that normally lives in small groups. It is omnivorous, eating small to medium-sized prey. Taxonomy Once thought to be synonymous with ''C. l. pallipes'' (the Indian wolf), the Arabian wolf was designated ''Canis lupus arabs'' by the British zoologist Reginald Innes Pocock in 1934. Pocock noted its smaller skull and smaller size. In the third edition of ''Mammal Species of the World'' published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf ''Canis lupus'' the subspecies ''Canis lupus arabs''. A 2014 study suggests that genetically the Arabian wolf is closer to ''C. l. lupus'' than it is to ''C. l. pallipes'' and supports the subspecies designation ''C. l. arabs''. There has been admixture with domestic dogs, but it is unclear whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Honshu Wolf
The Japanese wolf ( ja, ニホンオオカミ（日本狼）, ja, script=Latn, label= Hepburn, Nihon ōkami, or , below">#Nomenclature: "ōkami" and "yamainu"">below ''Canis lupus hodophilax''), also known as the Honshū wolf, is an extinct subspecies of the gray wolf that was once endemic to the islands of Honshū, Shikoku and Kyūshū in the Japanese archipelago. It was one of two subspecies that were once found in the Japanese archipelago, the other being the Hokkaido wolf. Phylogenetic evidence indicates that Japanese wolf was the last surviving wild member of the Pleistocene wolf lineage (in contrast to the Hokkaido wolf which belonged to the lineage of the modern day gray wolf), and may have been the closest wild relative of the domestic dog. Many dog breeds originating from Japan also have Japanese wolf DNA from past hybridization. Despite long being revered in Japan, the introduction of rabies and canine distemper to Japan led to the decimation of the population, an ...

Hokkaido Wolf
The Hokkaido wolf (''Canis lupus hattai''), also known as the and in Russia as the Sakhalin wolf,Heptner, V. G. & Naumov, N., P. (1998''Mammals of the Soviet Union'' Vol.II Part 1a, SIRENIA AND CARNIVORA (Sea cows; Wolves and Bears) Science Publishers, Inc., USA, pp. 193, is an extinct subspecies of gray wolf that once inhabited coastal north-east Asia. Its nearest relatives were the wolves of North America rather than Asia. It was exterminated in Hokkaido during the Meiji Restoration period, when American-style agricultural reforms incorporated the use of strychnine-laced baits to kill livestock predators. Stable URL: https://www.jstor.org/stable/1178791 Some taxonomists believe that it survived up until 1945 on the island of Sakhalin. It was one of two subspecies that were once found in the Japanese archipelago, the other being the Japanese wolf (''C. l. hodophilax'').

Mongolian Wolf
The Mongolian wolf (''Canis lupus chanco'') is a subspecies of gray wolf which is native to Mongolia, northern and central China, Korea, and the Ussuri region of Russia. Taxonomy ''Canis chanco'' was the scientific name proposed by John Edward Gray in 1863 who described a skin of a wolf that was shot in Chinese Tartary. This specimen was classified as a wolf subspecies ''Canis lupus chanco'' by St. George Jackson Mivart in 1880. In 1923, Japanese zoologist Yoshio Abe proposed separating the wolves of the Korean Peninsula from ''C. chanco'' as a separate species, ''C. coreanus'', because of their comparatively narrower muzzle. This distinction was contested by Reginald Pocock, who dismissed it as a local variant of ''C. chanco''. In the third edition of ''Mammal Species of the World'' published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf ''Canis lupus'' the taxonomic synonyms for the subspecies ''Canis lupus chanco''. Wozencraft classified ''C. cor ...

Steppe Wolf
The steppe wolf (''Canis lupus campestris''), also known as the Caspian Sea wolf, is a subspecies of grey wolf native to the Caspian steppes, the steppe regions of the Caucasus, the lower Volga region, southern Kazakhstan north to the middle of the Emba, and the steppe regions of the lower European part of the former Soviet Union. It may also occur in northern Afghanistan and Iran and occasionally the steppe regions of Romania and Hungary. The German name is ''der Steppenwolf'', whence the novel (1927) by German-Swiss author Hermann Hesse is named. Studies have shown that this type of wolf is known to carry rabies. Due to its close proximity to domestic animals, the need for a reliable vaccination is high. Rueness ''et al.'' (2014) showed that wolves in the Caucasus Mountains of the putative Caucasian subspecies, ''C. l. cubanensis'', are not genetically distinct enough to be considered a subspecies, but may represent a local ecomorph of ''C. l. lupus''. In Kazakhstan, village ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Wolf
The Indian wolf (''Canis lupus pallipes'') is a subspecies of gray wolf that ranges from Southwest Asia to the Indian Subcontinent. It is intermediate in size between the Himalayan wolf and the Arabian wolf, and lacks the former's luxuriant winter coat due to it living in warmer conditions. Within this subspecies, the "Indian plains wolf" is genetically basal to all other extant ''Canis lupus'' apart from the older-lineage Himalayan wolf, with both proposed as separate species. The Indian wolf travels in smaller packs and is less vocal than other variants of the gray wolf, and has a reputation for being cunning. The Indian wolf is one of the most endangered populations of gray wolf in the world. Taxonomy The Indian wolf was first described to Western science in 1831 by the British ornithologist William Henry Sykes under the binomial ''Canis pallipes''. In 1941, Reginald Pocock subordinated it to ''Canis lupus'' under the trinomial ''Canis lupus pallipes''. Pocock, R. I. (1941 ...

Tundra Wolf
The tundra wolf (''Canis lupus albus''), also known as the Turukhan wolf,Mech, L. David (1981), The Wolf: The Ecology and Behaviour of an Endangered Species', University of Minnesota Press, p. 353, is a subspecies of grey wolf native to Eurasia's tundra and forest-tundra zones from Finland to the Kamchatka Peninsula. It was first described in 1792 by Robert Kerr, who described it as living around the Yenisei, and of having a highly valued pelt.Kerr, R.
