The Madagascan fruit bat (Eidolon dupreanum) is a species of bat in the family Pteropodidae. It is endemic to Madagascar and is listed as "Vulnerable" by the IUCN because it is hunted as bushmeat.

Distribution and habitat

Eidolon dupreanum is named after the Governor of Réunion from 1864 to 1869, Marie Jules Dupré, for the help he gave to scientific researchers. [2] The Madagascan fruit bat is found both around the coastal plain and in the inland high plateau. It has not been recorded in some areas but that is likely to be because it has not been observed rather than that it is absent from these areas. It requires suitable rock fissures and caves in which to roost during the day. Colony size varies between about ten and five hundred individuals. [1]

Biology

Examination of the droppings from the Madagascan fruit bat show that it mainly consumes fruit but also feeds on the flowers of Eucalyptus spp. It was found to fly as far as 5 kilometres (3.1 mi) to reach trees of Polyscias spp. while largely neglecting the guava trees Psidium near its roost. Seeds smaller than about 7 mm (0.3 in) in diameter were swallowed. This helped with dispersal of the seed and it has been shown that seed germination was enhanced by their passage through the gut. [3] At times of year when fruit is not available, this bat feeds on nectar. It has been observed to visit the flowers of the rare baobab Adansonia suarezensis and the kapok tree Ceiba pentandra and it is believed to pollinate these trees. [4]

A single offspring is produced each year. This slow reproductive rate makes this bat susceptible to over-hunting. [5]

Status

In its Red List of Threatened Species, the IUCN has classified this bat as "Vulnerable". Its numbers appear to be declining and the greatest threat it faces is being hunted for bushmeat. Under Madagascar law, hunting this species is only permitted between the months of May and August. This legislation is widely disregarded and the bat is hunted at any time of year. Some colonies have been completely wiped out, but in some instances, these sites have been recolonised a few years later. The bat is present in a number of protected areas where it should receive protection. It is an adaptable species in that, if its main food sources are lost, it is able to change to other sources although it seems to prefer the fruit of native trees to those of introduced species. [1]

<span class="mw-page-title-main">Megabat</span> Family of fruit bats

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.

<i>Pteropus</i> Genus of large bats

Pteropus 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 species in the genus.

Peters's wrinkle-lipped bat, also called Peters's goblin bat, is a species of bat in the family Molossidae, the free-tailed bats. It is endemic to Madagascar, where it is widespread and in some areas abundant. It commonly roosts in human-made structures, sometimes in colonies with other free-tailed bat species. It forages in the open, often in agricultural areas. The bat is sexually dimorphic, with males larger than females.

<span class="mw-page-title-main">Straw-coloured fruit bat</span> Species of mammal

The straw-coloured fruit bat is a large fruit bat that is the most widely distributed of all the African megabats. It is quite common throughout its area ranging from the southwestern Arabian Peninsula, across forest and savanna zones of sub-Saharan Africa. It is listed as Near Threatened on the IUCN Red List due to a decreasing population trend. Straw-coloured fruit bats travel in massive colonies of at least 100,000 bats and sometimes massing up to 1 million. From October to end of December every year, in the largest migration of mammals on the planet, up to 10 million straw-coloured fruit bats congregate in Kasanka National Park, Zambia, roosting in a 2 hectare area of Mushitu forest each day. This migration was only discovered in 1980. Their necks and backs are a yellowish-brown colour, while their undersides are tawny olive or brownish.

The Madagascar sucker-footed bat, Old World sucker-footed bat, or simply sucker-footed bat is a species of bat in the family Myzopodidae endemic to Madagascar, especially in the eastern part of the forests. The genus was thought to be monospecific until a second species, Myzopoda schliemanni, was discovered in the central western lowlands. It was classified as Vulnerable in the 1996 IUCN Red List of Threatened Species but is now known to be more abundant and was reclassified in 2008 as of "Least Concern".

<span class="mw-page-title-main">Indian flying fox</span> Species of mammal

The Indian flying fox, also known as the greater Indian fruit bat, is a species of flying fox native to the Indian subcontinent. It is one of the largest bats in the world. It is of interest as a disease vector, as it is capable of transmitting several viruses to humans. It is nocturnal and feeds mainly on ripe fruits, such as mangoes and bananas, and nectar. This species is often regarded as vermin due to its destructive tendencies towards fruit farms, but the benefits of its pollination and seed propagation often outweigh the impacts of its fruit consumption.

<span class="mw-page-title-main">Gray flying fox</span> Species of mammal

The gray flying fox is a species of flying fox in the family Pteropodidae. It is not to be confused with the grey flying fox. It is found in Indonesia, but not in the Philippines, despite occasional reference to such. Very little is known about this species. The gray flying fox has small size and neutral coloration with a brownish head and an orange abdomen. It probably roosts individually or in small groups. It was listed on appendix II of CITES, and is classified as "Data Deficient" by the IUCN. This species has been decimated by hunting for bushmeat in Indonesia. The hunters use fishing hooks, ropes, and other supplies to hunt the bats. The ropes and hooks are placed along their flight paths, tearing and ensnaring the bats' wings when are flying. In the course of a hunting season, entire colonies can be killed.

<i>Triaenops menamena</i> Bat species found in Madagascar

Triaenops menamena is a bat in the genus Triaenops found on Madagascar, mainly in the drier regions. It was known as Triaenops rufus until 2009, when it was discovered that that name had been incorrectly applied to the species. Triaenops rufus is a synonym of Triaenops persicus, a Middle Eastern species closely related to T. menamena— the Malagasy species had previously been placed as a subspecies of T. persicus by some authors. Triaenops menamena is mostly found in forests, but also occurs in other habitats. It often roosts in large colonies and eats insects such as butterflies and moths. Because of its wide range, common occurrence, and tolerance of habitat degradation, it is not considered to be threatened.

Commerson's roundleaf bat, also known as Commerson's leaf-nosed bat, is a species of bat endemic to Madagascar. It is named after French naturalist Philibert Commerson (1727-1773). Bat populations of Africa or São Tomé and Príncipe formerly considered part of this species are now classified separately as M. gigas, M. thomensis or M. vattatus, while one from Madagascar was split off to become M. cryptovalorona. It was formerly placed in the genus Hipposideros, but moved to the resurrected Macronycteris in 2017 on the basis of molecular evidence.

<i>Chaerephon jobimena</i> Species of bat

Chaerephon jobimena, commonly known as the black and red free-tailed bat, is a species of bat in the family Molossidae. It is endemic to western Madagascar. With a forearm length of 45 to 48 mm, C. jobimena is somewhat larger than other Malagasy bats assigned to Chaerephon, but similar in size to Tadarida aegyptiaca.
