Rousettus is a genus of Old World fruit bats or megabats, referred to as rousette bats. The genus is a member of the family Pteropodidae. The genus consists of seven species [1] that range over most of Africa to southeast Asia, and the islands of the south Pacific. They are among the few megabats capable of echolocation, and the only genus of megabats known to use vocal echolocation. [2]
Genus Rousettus – rousette fruit bats
The species in the genera Boneia , Stenonycteris , and Pilonycteris were also formerly classified in Rousettus, but phylogenetic analysis supports them being their own genera.
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.
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.
Cynopterus is a genus of megabats. The cynopterine section is represented by 11 genera, five of which occur in Malaysia, namely, Chironax, Balionycteris, Penthetor, Dyacopterus, and Cynopterus. About 30 names for Cynopterus species have been proposed, but only 16 are taxonomically valid forms.
The Egyptian fruit bat or Egyptian rousette is a species of megabat that occurs in Africa, the Middle East, the Mediterranean and the Indian subcontinent. It is one of three Rousettus species with an African-Malagasy range, though the only species of its genus found on continental Africa. The common ancestor of the three species colonized the region in the late Pliocene or early Pleistocene. The species is traditionally divided into six subspecies. It is considered a medium-sized megabat, with adults weighing 80–170 g (2.8–6.0 oz) and possessing wingspans of approximately 60 cm (24 in). Individuals are dark brown or grayish brown, with their undersides paler than their backs.
Geoffroy's rousette is a species of megabat or Old World fruit bats. It is one of ten species in the genus Rousettus.
The bare-backed rousette is a species of megabat.
Peters's dwarf epauletted fruit bat is a species of megabat in the family Pteropodidae. It is found in Angola, Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, Sudan, Tanzania, Togo, Uganda, and Zambia. Its natural habitats are subtropical or tropical moist lowland forests and moist savanna.
The Manado fruit bat is a species of megabat in the family Pteropodidae.
The Sulawesi rousette or Sulawesi fruit bat is a species of megabat in the family Pteropodidae endemic to Sulawesi, an island in Indonesia. It is presently the only member of the genus Pilonycteris.
The long-haired fruit bat, also known as the long-haired rousette, is a species of megabat in the family Pteropodidae. It is the only member of the genus Stenonycteris. It was formerly classified in the genus Rousettus until a 2013 phylogenetic study found it to belong to its own genus and tribe.
The Madagascan rousette or Madagascar rousette, is a species of megabat in the family Pteropodidae endemic to Madagascar. Its natural habitat is subtropical or tropical dry forests.
Syconycteris is a genus of megabat in the family Pteropodidae. There are three described species at present, with more likely to be added. Members of this genus are found in Indonesia, New Guinea and Australia. Their diet mainly consists of nectar and fruit, making them important for pollination and seed dispersal in their environment.
In evolutionary biology, the flying primate hypothesis is that megabats, a subgroup of Chiroptera, form an evolutionary sister group of primates. The hypothesis began with Carl Linnaeus in 1758, and was again advanced by J.D. Smith in 1980. It was proposed in its modern form by Australian neuroscientist Jack Pettigrew in 1986 after he discovered that the connections between the retina and the superior colliculus in the megabat Pteropus were organized in the same way found in primates, and purportedly different from all other mammals. This was followed up by a longer study published in 1989, in which this was supported by the analysis of many other brain and body characteristics. Pettigrew suggested that flying foxes, colugos, and primates were all descendants of the same group of early arboreal mammals. The megabat flight and the colugo gliding could be both seen as locomotory adaptations to a life high above the ground.
Bats are flying mammals of the order Chiroptera. 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, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is 29–34 mm (1.1–1.3 in) in length, 150 mm (5.9 in) across the wings and 2–2.6 g (0.071–0.092 oz) in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox reaching a weight of 1.6 kg (3.5 lb) and having a wingspan of 1.7 m.
The bat virome is the group of viruses associated with bats. Bats host a diverse array of viruses, including all seven types described by the Baltimore classification system: (I) double-stranded DNA viruses; (II) single-stranded DNA viruses; (III) double-stranded RNA viruses; (IV) positive-sense single-stranded RNA viruses; (V) negative-sense single-stranded RNA viruses; (VI) positive-sense single-stranded RNA viruses that replicate through a DNA intermediate; and (VII) double-stranded DNA viruses that replicate through a single-stranded RNA intermediate. The greatest share of bat-associated viruses identified as of 2020 are of type IV, in the family Coronaviridae.
Lubee Bat Conservancy is a nonprofit organization in Gainesville, Florida. The organization was founded in 1989 by Luis F. Bacardi as a center for the research, conservation, and breeding of endangered animals; it later narrowed its focus solely to bats, particularly megabats.
The Rousettinae are a subfamily of megabats. Taxa within this subfamily include:
The outbreak of Marburg virus disease in Gueckedou district, Guinea started in July 2021, and ended in September. A single individual got sick and died of the virus, with no other known cases.
