Yinpterochiroptera
The Yinpterochiroptera (or Pteropodiformes) is a suborder of the Chiroptera, which includes taxa formerly known as megabats and five of the microbat families: Rhinopomatidae, Rhinolophidae, Hipposideridae, Craseonycteridae, and Megadermatidae. This suborder is primarily based on molecular genetics data. This proposal challenged the traditional view that megabats and microbats form monophyletic groups of bats. Further studies are being conducted, using both molecular and morphological cladistic methodology, to assess its merit. The term Yinpterochiroptera is constructed from the words Pteropodidae (the family of megabats) and Yinochiroptera (a term proposed in 1984 by Karl F. Koopman to refer to certain families of microbats). Recent studies using transcriptome data have found strong support for the Yinpterochiroptera-Yangochiroptera classification system. Researchers have created a relaxed molecular clock that estimates the divergence between Yinpterochiroptera and Yangochirop ...

Chiroptera
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 ...

Megabat
Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or—especially the genera ''Acerodon'' and ''Pteropus''—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described. The leading theory of the evolution of megabats has been determined primarily by genetic data, as the fossil record for this family is the most fragmented of all bats. They likely evolved in Australasia, with the common ancestor of all living pteropodids existing approximately 31 million years ago. Many of their lineages probably originated in Melanesia, then dispersed over time to mainland Asia, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yangochiroptera
Yangochiroptera, or Vespertilioniformes, is a suborder of Chiroptera that includes most of the microbat families, except the Rhinopomatidae, Rhinolophidae, Hipposideridae, and Megadermatidae. These other families, plus the megabats, are seen as part of another suborder, the Yinpterochiroptera. All bats in Yangochiroptera use laryngeal echolocation(LE), which involves the use of high-frequency sounds to detect prey and avoid obstacles. The rationale for the Yangochiroptera taxon is primarily based on molecular genetics data. The Yangochiroptera/ Yinpterochiroptera classification remains a relatively recent proposal, which challenges the traditional view that megabats and microbats form monophyletic groups by claiming that the superfamily Rhinolophoidea is more closely related to Old World fruit bats than other microbats. Further studies are being conducted, using both molecular and morphological cladistic methodology, to assess the merit of this alternative view of bat evolut ...

Pteropus
''Pteropus'' (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 Extant taxon, extant species in the genus. Flying foxes eat fruit and other plant matter, and occasionally consume insects as well. They locate resources with their keen sense of smell. Most, but not all, are nocturnality, nocturnal. They navigate with keen eyesight, as they cannot Animal echolocation, echolocate. They have R/K selection theory#K-selection, long life spans and low reproductive outputs, with females of most species producing only one offspring per year. Their slow life history makes their populations vulnerable to threats such as Overexploitation, overhunting, culling, and natural disasters. Six flying fox species have been ...

Microbats
Microbats constitute the suborder Microchiroptera within the order Chiroptera (bats). Bats have long been differentiated into Megachiroptera (megabats) and Microchiroptera, based on their size, the use of echolocation by the Microchiroptera and other features; molecular evidence suggests a somewhat different subdivision, as the microbats have been shown to be a paraphyletic group. Characteristics Microbats are long. Most microbats feed on insects, but some of the larger species hunt birds, lizards, frogs, smaller bats or even fish. Only three species of microbat feed on the blood of large mammals or birds ("vampire bats"); these bats live in South and Central America. Although most "Leaf-nose" microbats are fruit and nectar-eating, the name “leaf-nosed” isn't a designation meant to indicate the preferred diet among said variety. Three species follow the bloom of columnar cacti in northwest Mexico and the Southwest United States northward in the northern spring and then ...

Hipposideridae
The Hipposideridae are a 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 tribes, one with two subtribes, but these tribes turned out to be non- monophyletic and have been abandoned. A different classification was proposed by Hand and Kirsch in 2003. In 2009, Petr Benda and Peter Vallo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megadermatidae
Megadermatidae, or false vampire bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a wide membrane between the hind legs, or uropatagium, but no tail. Many species are a drab brown in color, but some are white, bluish-grey or even olive-green, helping to camouflage them against their preferred roosting environments. They are primarily insectivorous, but will also eat a wide range of small vertebrates. Description False vampire bats are relatively large, with combined head and body lengths that range from . Their forearm lengths range from . They all lack tails. The ghost bat is the largest member of the family. All the species have very large ears with divided tragi. They have long nose-leaves. All species are similar in that they lack upper incisors, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...
