Andaman Horseshoe Bat
The Andaman horseshoe bat (''Rhinolophus cognatus'') is a species of bat in the family Rhinolophidae. It is endemic to the Andaman Islands. During the day, it roosts in caves, but may also choose tree hollows. Taxonomy The Andaman horseshoe bat was first collected by Italian zoologist Enrico Hillyer Giglioli in May 1892. It was collected in Port Blair of the Andaman Islands. The specimen was taken to the Museo Civico di Storia Naturale di Genova, where it was described by Danish zoologist Knud Andersen in 1906.Andersen, K. (1906). On some new or little-known bats of the genus ''Rhinolophus'' in the collection of the Museo Civico, Genoa. Annali del Museo Civico di Storia Naturalia di Genova, Serie, 3(2), 1905. As the horseshoe bat genus is very speciose, it is further divided into closely related species groups. The Andaman horseshoe bat is placed into the ''pusillus'' species group.Srinivasulu, C., & Srinivasulu, B. (2012). South Asian Mammals. In South Asian Mammals (pp. 9 ...

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 Chiropt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortridge's Horseshoe Bat
Shortridge's horseshoe bat (''Rhinolophus shortridgei'') is a species of Horseshoe bat native to Northeast India, northern Myanmar, and southern China. It was first described in 1918 by Knud Andersen, and was considered a subspecies of Blyth's horseshoe bat until 2003 when the two species were collected in sympatry. Description It is of medium size with a long mandible and a nose leaf which does not completely cover its nostril. It has brown fur with a relatively pale underside. Range and conservation status In China, the species is found in Yunnan, Sichuan, Guizhou, Hunan, Guangxi, Hubei, Hainan, Guangdong and Fujian provinces. It is also found in northern parts of India and in Myanmar. There is limited data on the habitat of ''R. shortridgei'' but specimens have been collected from a dipterocarp Dipterocarpaceae is a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees.

Wildlife Protection Act, 1972
The Wild Life (Protection) Act, 1972 is an Act of the Parliament of India enacted for protection of plants and animal species. Before 1972, India had only five designated national parks. Among other reforms, the Act established scheduled protected plant and hunting certain animal species or harvesting these species was largely outlawed. The Act provides for the protection of wild animals, birds and plants; and for matters connected therewith or ancillary or incidental thereto. It extends to the whole of India. It has six schedules which give varying degrees of protectionSchedule Iand part II oprovide absolute protection - offences under these are prescribed the highest penalties.

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon is Vulnerable when it is not critically endangered or Endangered but ...

Generation Time
In population biology and demography, generation time is the average time between two consecutive generations in the lineages of a population. In human populations, generation time typically ranges from 22 to 33 years. Historians sometimes use this to date events, by converting generations into years to obtain rough estimates of time. Definitions and corresponding formulas The existing definitions of generation time fall into two categories: those that treat generation time as a renewal time of the population, and those that focus on the distance between individuals of one generation and the next. Below are the three most commonly used definitions: The time it takes for the population to grow by a factor of its net reproductive rate The net reproductive rate \textstyle R_0 is the number of offspring an individual is expected to produce during its lifetime (a net reproductive rate of 1 means that the population is at its demographic equilibrium). This definition envisions the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpor
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor". Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy. Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This ...

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 The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the ta ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines o ...
