Andersen's Leaf-nosed Bat
''Hipposideros gentilis'', commonly known as Andersen's leaf-nosed bat or Andersen's roundleaf bat, is a species of roundleaf bat found in Asia. Taxonomy ''Hipposideros gentilis'' was described as a new species in 1918 by Danish mammalogist Knud Andersen. The holotype had been collected by Edward Yerbury Watson near Thayet, Myanmar. Submitted by his colleague Oldfield Thomas, it was Andersen's final credited publication due to his mysterious disappearance that same year. Andersen additionally described three subspecies as well as the nominate (''H. gentilis gentilis''): *''H. gentilis sinensis'' *''H. gentilis atrox'' *''H. gentilis major'' In 1963, British mammalogist John Edwards Hill published that he considered all the subspecies of ''H. gentilis'' as subspecies of the bicolored roundleaf bat (''H. bicolor''). He later considered ''H. g. gentilis'' and ''H. g. sinensis'' as subspecies of the Pomona roundleaf bat (''H. pomona''). A 2018 publication stated that ''H. gentil ...

Knud Andersen (mammalogist)
Knud Christian Andersen (29 April 1867 in Frederiksberg – last seen alive June 1918 in England) was a Danish zoologist. His research focused on bats. Life and work Towards the end of the 19th century, Andersen first worked as an ornithologist and ran field studies on the Faroe Islands. In 1901 Ferdinand I awarded him an appointment at the Zoological Museum of Sofia. Due to his frustration with the working conditions, he gave up this position.Jon Fjeldså: ''Danske ornitologer langt fra hjemmet: fra P.W. Lund til international fuglebeskyttelse'' In: ''100-års festskrift'' Dansk Orn. Foren. Tidsskr. 100 (2006):S. 265-275 In 1904, he was hired by the British Museum to research bats in the Pacific, in South-East Asia and in Queensland. He was especially interested in the genus Flying Fox and Horseshoe bats, of which he described 15 new species. He published 13 scientific papers on the South-East Asian Horseshoe bats. His most famous work was his ''Catalogue of the Chiropter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pomona Roundleaf Bat
The Pomona roundleaf bat, Pomona leaf-nosed bat, or Andersen's leaf-nosed bat (''Hipposideros pomona'') is a species of bat in the family Hipposideridae that is endemic to India. Taxonomy It was described as a new species in 1918 by Danish mammalogist Knud Andersen. The holotype had been collected in what was then the Coorg Province of India by G. C. Shortridge. The Vietnam leaf-nosed bat, ''Paracoelops megalotis'', formerly known as its own species based on one specimen, is now recognized as synonymous with the pomona roundleaf bat. In 2012, researchers determined that all the features of ''P. megalotis'' match the pomona roundleaf bat. Their skulls and teeth were identical, and the ''P. megalotis'' specimen is indistinguishable from pomona roundleaf bat individuals. The Integrated Taxonomic Information System, responsible for managing taxonomy of species, no longer recognizes ''Paracoelops'' as a valid genus nor ''P. megalotis'' as a valid species.

Taxa Named By Knud Andersen
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hipposideros
''Hipposideros'' is one of the most diverse genera of bats, with more than 70 species. They are collectively called roundleaf bats after the shape of their nasal ornament. It is the type genus of the family Hipposideridae. It is divided into species groups based on morphology. Some species that were previously placed in ''Hipposideros'' are now placed in the related genera '' Doryrhina'' and '' Macronycteris''. Conversely, the genus ''Paracoelops'', which was considered distinct until 2012, is now synonymized with ''Hipposideros'', as the only species turned out to be based on a specimen of '' Hipposideros pomona''.

Hipposideros Atrox
''Hipposideros atrox'', commonly known as the lesser bicolored leaf-nosed bat, is a species of bat found in Southeast Asia. Originally described as a subspecies in 1918, it was recognized as a full species in 2010. It uses echolocation to navigate and find prey, and roosts in caves during the day. Taxonomy ''Hipposideros atrox'' was described as a new subspecies of ''Hipposideros gentilis'' by Danish mammalogist Knud Andersen in 1918; he described ''H. gentilis'' in the same publication. The holotype had been collected by Arthur Lennox Butler in the Malaysian state of Selangor. ''Hipposideros gentilis'' has been recognized as a synonym of the Pomona roundleaf bat (''Hipposideros pomona''). In 1963, British mammalogist John Edwards Hill included ''H. atrox'' as a subspecies of the bicolored roundleaf bat (''Hipposideros bicolor''). However, in 2010 ''H. atrox'' was recognized as a distinct species for the first time, which was followed by the IUCN in 2019. Description ''H. atrox ...

Animal Echolocation
Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the Echo (phenomenon) , echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for animal navigation , navigation, foraging, and predation, hunting prey. Echolocation calls can be Frequency modulation, frequency modulated (FM, varying in pitch during the call) or constant frequency (CF). FM offers precise range discrimination to localize the prey, at the cost of reduced operational range. CF allows both the prey's velocity and its movements to be detected by means of the Doppler effect. FM may be best for close, cluttered environments, while CF may be better in open environments or for hunting while perched. Echolocating animals include mammals, especially odontocetes (toothed whales) and some bat species, and, using s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nose-leaf
A nose-leaf, or leaf nose, is an often large, lance-shaped nose, found in bats of the Phyllostomidae, Hipposideridae, and Rhinolophidae families. Because these bats Animal echolocation, echolocate nasally, this nose-leaf is thought to serve a role in modifying and directing the echolocation call. The shape of the nose-leaf can be important for identifying and classifying bats. Furthermore, the shape of the nose-leaf can identify behavior of the bat itself; for example, in the families that have the nose-leaf, experiments have shown it to act as a baffle and focus their emission beams.

Baculum
The baculum (: bacula), also known as the penis bone, penile bone, ''os penis'', ''os genitale'', or ''os priapi'', is a bone in the penis of many placental mammals. It is not present in humans, but is present in the penises of some primates, such as the gorilla and the chimpanzee. The baculum arises from primordial cells in soft tissues of the penis, and its formation is largely influenced by androgens. The bone lies above the male urethra, urethra, and it aids sexual reproduction by maintaining stiffness during sexual penetration. The Homology (biology), homologue to the baculum in female mammals is the baubellum (''os clitoridis''), a bone in the clitoris. Etymology The word ''baculum'' means "stick" or "staff" in Latin and originates from , ''baklon'' "stick". Function The baculum is used for copulation and varies in size and shape by species. Its evolution may be influenced by sexual selection, and its characteristics are sometimes used to differentiate between simila ...

Bicolored Roundleaf Bat
The bicolored roundleaf bat (''Hipposideros bicolor'') is a species of bat in the family Hipposideridae found in Indonesia, Malaysia, Singapore, the Philippines, Thailand, and Timor-Leste. This bat inhabits caves, rock crevices and tunnels among lowland forests. They roost in large numbers and consume mostly small winged insects. Their navigation and hunting skills come from the use of echolocation. Its leafnose is used to release ultrasonic shouts to distinguish its surroundings. Echolocation is also used to distinguish other species based on their wingbeat and size. The habitat of this bat decides the color of its fur. Bleaching fumes of a cave environment will cause an orange colored fur. Those who inhabit a well-ventilated roost will be a light brown color. Taxonomy It was described as a new species in 1834 by Dutch zoologist Coenraad Jacob Temminck. Temminck placed it in the genus '' Rhinolophus'' with a binomial of ''R. bicolor''. The bicolored leafnose bat has four subspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hipposideridae
The Hipposideridae are a family (biology), family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family.Simmons, 2005, p. 365 Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera. Taxonomy The Hipposideridae contain 10 living genera and more than 70 species, mostly in the widespread genus ''Hipposideros''. In addition, several fossil genera are known; the oldest fossils attributed to the family are from the middle Eocene of Europe. In their 1997 ''Classification of Mammals'', Malcolm C. McKenna and Susan K. Bell proposed a division of Hipposideridae (called Rhinonycterinae in their work) into three tribe (taxonomy), tribes, one with two subtribes, but these tribes turned out to be non-monophyly, monophyletic and have been abandoned. A different classification was proposed by Hand and Kirsch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Edwards Hill
John Edwards Hill (11 June 1928 – 6 May 1997) was a British mammalogist who described 24 species and 26 subspecies during his career. Early life and education Hill was born on 11 June 1928 in the small hamlet of Colemans Hatch in East Sussex, England. He was the only child of Marjorie Edwards and her husband Albert Hill. He attended East Grinstead Grammar School on scholarship. During World War II, his father worked as a gardener and his mother worked as a housekeeper. Hill finished Grammar School after the war in 1946 at eighteen years old. Career After finishing school, Hill joined the Air Ministry's Meteorological Office as a Meteorological Assistant. He then served in the Royal Air Force for two years as a Meteorological Assistant, during which he traveled to Japan, Singapore, and the Nicobar Islands. In 1948, he began working as an Assistant Experimental Officer at the British Museum (Natural History)'s Department of Zoology. He retired from the Museum 40 years later in 1 ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, 1st Baronet, Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
