Chinese Rufous Horseshoe Bat
The Chinese rufous horseshoe bat (''Rhinolophus sinicus'') is a species of bat in the family Rhinolophidae. It is found in Bhutan, China, India, Nepal, and Vietnam. The species is most easily confused with '' R. affinis'', from which it is best distinguished by its straight-sided lancet and the relatively short second phalanx of the third digit (< 66% of the length of the ; Csorba ''et al''. 2003). Subspecies ''Rhinolophus sinicus'' is divided into the following two subspecies: * ''R. s. septentrionalis'' * ''R. s. sinicus''Description The Chinese rufous horseshoe bat has a forearm length of . It has an ear length of and a tail length of . Overall, it is considered a medium-sized horseshoe bat. It is similar in appearance to the |
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 Chiroptera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maternity Colonies
A maternity colony refers to a temporary association of reproductive female bats for giving birth to, nursing, and weaning their pups. The colonies are initiated by pregnant bats. After giving birth, the colony consists of the lactating females and their offspring. After weaning, juveniles will leave the maternity colony, and the colony itself will break apart. The size of a maternity colony is highly variable by species, with some species forming colonies consisting of ten or fewer individuals, while the largest maternity colony in the world in Bracken Cave is estimated to have over 15 million bats. Benefits of a maternity colony Maternity colonies are especially prevalent in temperate regions due to the thermal benefits of roosting with other individuals.Dietz, M., & Kalko, E. K. (2006).

Mammals Described In 1905
Mammals () are a group of vertebrate animals constituting the class (biology), class Mammalia (), characterized by the presence of mammary glands which in Female#Mammalian female, females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three ossicles, middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they Genetic divergence, diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant taxon, extant species of mammals have been described divided into 29 Order (biology), orders. The largest Order (biology), orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, Mole (animal), moles, shrews, and others).

Mammals Of Nepal
Wildlife diversity is a notable feature of Nepal. Because of the variance in climate, from tropical to arctic, Nepal has a large variety of plants and animals. Wildlife tourism is also a major source of tourism in the country. There are some animal species which are unique to Nepal, such as the spiny babbler. Nepal is also host to many rhododendron species. The wildlife of Nepal includes its flora and fauna. Nepal has established numerous national parks and reserves in order to protect its diverse fauna. Nepal is a biodiversity hot spot with ecoregions broadly comprising the mountainous ecoregion, the savanna and grasslands ecoregion of the terai (foothills), and the Rara Lake ecoregion, which has many endemic species. Legal protection Nepal has established numerous national parks and reserves in order to protect its diverse fauna ever since 1973, with the passing of the National Parks and Wildlife Conservation Act 2029 BS. There are four different "classes" of protection, rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bats Of China
Bats are mammals of the Order (biology), order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, Bat flight, flying with their very long spread-out digits covered with a thin skin, membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the Flying fox#Physical characteristics, flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the Animal echolocation, echolocating microbats. But more r ...

Bat SARS-like Coronavirus WIV1
Bat SARS-like coronavirus WIV1 (Bat SL-CoV-WIV1), also sometimes called SARS-like coronavirus WIV1, is a strain of '' severe acute respiratory syndrome–related coronavirus'' (SARSr-CoV) isolated from Chinese rufous horseshoe bats in 2013 ('' Rhinolophus sinicus''). Like all coronaviruses, virions consist of single-stranded positive-sense RNA enclosed within an envelope. Zoonosis The discovery confirms that bats are the natural reservoir of SARS-CoV. Phylogenetic analysis shows the possibility of direct transmission of SARS from bats to humans without the intermediary Chinese civets, as previously believed.Vineet D.

Severe Acute Respiratory Syndrome–related Coronavirus
''Severe acute respiratory syndrome–related coronavirus'' (SARSr-CoV or SARS-CoV)The terms ''SARSr-CoV'' and ''SARS-CoV'' are sometimes used interchangeably, especially prior to the discovery of SARS-CoV-2. This may cause confusion when some publications refer to SARS-CoV-1 as ''SARS-CoV''. is a species of virus consisting of many known strains phylogenetically related to severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1) that have been shown to possess the capability to infect humans, bats, and certain other mammals. These enveloped, positive-sense single-stranded RNA viruses enter host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor. The SARSr-CoV species is a member of the genus ''Betacoronavirus'' and of the subgenus ''Sarbecovirus'' (SARS Betacoronavirus). Two strains of the virus have caused outbreaks of severe respiratory diseases in humans: severe acute respiratory syndrome coronavirus 1 (SARS-CoV or SARS-CoV-1), which caused the 20 ...

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Haemadipsidae
__NOTOC__ Haemadipsidae (From Greek "haima" and "dipsa" ("blood" and "thirst", respectively)) are a family of jawed leeches. They are a monophyletic group of hirudiniform proboscisless leeches. These leeches have five pairs of eyes, with the last two separated by two eyeless segments. The family is monotypic, containing only the subfamily Haemadipsinae, though as the family can apparently be divided into two or three distinct lineages, at least one of the proposed splits, while not a distinct family, might be a valid subfamily. Haemadipsids have two or three jaws. The two-jawed (duognathous) species were classified in a number of largely monotypic or non-monophyletic genera, so they were placed into a single monophyletic genus called ''Chtonobdella''. To increase grip, their caudal suckers have textured "friction" or "sucker" rays. Commonly known as jawed land leeches, these annelids are known from subtropical and tropical regions around the Indian and Pacific Ocean. Well-kn ...

Sinospelaeobdella
''Sinospelaeobdella'' is a genus of jawed land leech, endemic to caves in China. It contains the species ''S. cavatuses'' (previously ''Haemadipsa cavatuses'') and ''S. wulingensis'', the latter being named after the Wuling Mountains where it was found. The diet of this genus is unique among the land leeches, as it exclusively feeds off blood of cave dwelling bats. Its central diet is based on ''Rhinolophus sinicus The Chinese rufous horseshoe bat (''Rhinolophus sinicus'') is a species of bat in the family Rhinolophidae.

Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffic ...
