Great Evening Bat
The great evening bat (''Ia io'') is the largest bat in the vesper bat family (Vespertilionidae) and the only living species in the genus '' Ia''. It is common to Eastern and Southeastern Asia (China, India, Laos, Nepal, Thailand and Vietnam), mainly living in areas with limestone caves at altitudes of . Their roost sites have been found both near the cave entrances and up to within the cave systems. Description The great evening bat reaches a length of . It is colored brown on the top and grayish on the bottom. Average wingspan is and it typically weighs . Not much is known about its habits and behavior. The bat usually lives in small groups. Its food consists of insects, as with most vesper bats. The great evening bat also sometimes feeds on small birds. The bat leaves its sleeping place in the late afternoon to search of food. During the winter months it may migrate to warmer regions. Status The IUCN lists its conservation status as near-threatened. One of the threats to i ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the 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, 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 Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Oldfield Thomas
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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesper Bats
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus ''Vespertilio'', which takes its name from a word for bat, ', derived from the Latin term ' meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds". (The term "evening bat" also often refers more specifically to one of the species, '' Nycticeius humer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Short Species Names
Living organisms are known by scientific names. These binomial names can vary greatly in length, and some can be very short; genus or species names composed of only one letter are not allowed by any of the nomenclature codes, but any combination of two letters and above can be valid if it has not been previously used. This list of shortest species names lists the scientific binomials with the fewest letters. The longest scientific species names can be found in the List of long species names. 4 letters *'' Ia io'' Thomas, 1902 – Family Vespertilionidae. The great evening bat is the largest vespertilionid bat, reaching a wingspan of just over half a metre. It occurs in tropical Asia where it lives in limestone caves. Apart from being the shortest scientific name of a living organism (and one of the shortest possible, since anything below 4 letters would not be allowed), it also has the peculiarity of being composed only of vowels. The specific name probably refers to Io, a wom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
