Syconycteris (blossom bat) is a genus of megabat in the family Pteropodidae. [1] 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.
Syconycteris bats play an especially important role as pollinators for flowers that require an explosive opening such as Mucuna macrocarpa . This is where the stamen and pistill are covered until exposed by an animal. Syconycteris opens the flower by pushing their snout into the basal section between the banner and carina and then pressing their wings to open. Syconycteris bats are primary pollinators as the pollen of explosively opened flowers sticks to their fur. [2]
Syconycteris is a long tongued nectar feeding bat. They are small compared to other megabats and swarm around tall fruit trees. [3] Like closely related Macroglossus species, their vocalizations consist of a long series of similar trill like bursts with high repetition rate and small changes in dominant frequency. They vocalize when distressed and when fighting against other bats over food. [4] The similarity to the echolocating bat Rousettus has led to hypthotheses that Syconycteris is also capable of echolocation. [4]
The Etolo tribe of New Guinea will sometimes include Syconycteris bats in their diet, along with other bats. [5]
Syconycteris is unique among megabats bats because they do not produce spats. Spats are created by slow feeding bats that chew and swallow the juices of their food while pressing the pulp and seeds into a spat or wadge which is then spit out. This makes them more effective seed dispersers because seeds in spats tend to travel less distance and are more vulnerable to fungi compared to seeds that are defecated like those eaten by Syconycteris. [6]
They are part of the Australasian nectarivorous clade along with the genus Macroglossus . [7] Its placement in this clade has changed over time as studies in DNA testing have grown more in depth. Previously the two were thought to make up Cynopterinae, [4] but it was later found the Cynopterinae is monophyletic and not closely related to Syconycteris. [8] The experiment was the most inclusive analysis of molecular data for pteropodids to date. It used data from five loci. Four mitochondrial and one nuclear gene representing 43 species including exemplars from seven cynopterine genera. Later reanalysis with more sequences using different substitution to gap costs resulted in the current classification. Inclusion of 236 non-molecular characters, mostly morphological, supported the trees. Nyctimeninae and Cynopterinae were found to not be closely related to Syconycteris as previously thought because both are monophyletic. [8] Grouping Syconycteris with Macroglossus has been supported by further studies into mitochondrial DNA. [9] Syconycteris has appeared only recently in the fossil records with no ancestor fossils recovered yet. [10]
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.
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.
The long-tongued nectar bat, also known as the northern blossom bat, honey nectar bat, least blossom-bat, dagger-toothed long-nosed fruit bat, and lesser long-tongued fruit bat, is a species of megabat. M. minimus is one of the smallest species in the family Pteropodidae, with an average length of 60–85 mm. It has a reddish-brown colouring with relatively long hair compared to the other species. The hair on the abdomen is a lighter colour, and a dark brown stripe runs bilaterally down the top of the head and back.
The eastern or Queensland tube-nosed bat is a megabat in the family Pteropodidae that lives in north-eastern Australia. N. robinsoni is one of the few species of megabat that roosts solitarily. They get their common name from their raised tubular nostrils which are unlike those of most other species in the family. They are a deep brown with gray heads and sparse yellow spotting.
The common blossom bat also known as the southern blossom bat or Queensland blossom bat, is a megabat in the family Pteropodidae. The common blossom bat feeds mostly on nectar and pollen rather than fruit. It is one of eight Pteropodidae species on mainland Australia. It is one of the smallest of all nectarivorous megabats.
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 lesser tube-nosed fruit bat or unstriped tube-nosed bat is a species of megabat in the family Pteropodidae found in West Papua, Indonesia and Papua New Guinea.
The Ryukyu flying fox or Ryukyu fruit bat is a species of megabat in the family Pteropodidae. It is found in Japan, Taiwan, and the Batanes and Babuyan Islands of the Philippines. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical swamps. It is threatened by habitat loss and by hunting for food and the IUCN classify it as "Vulnerable".
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 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.
The Halmahera blossom bat is a species of megabat in the family Pteropodidae. It is endemic to Halmahera and Bacan islands, of the northern Maluku Islands archipelago in Indonesia.
The moss-forest blossom bat is a species of megabat in the family Pteropodidae found in New Guinea. Its natural habitat is subtropical and tropical dry forests.
The megabat subfamily Macroglossusinae is within the family Pteropodidae.
The Yinpterochiroptera 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.
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.
Nyctimene is a genus of bats in the Pteropodidae family. Commonly known as tube-nosed fruit bats, they are found in the central Philippines, eastern Indonesia, Papua New Guinea and the north-east coast of Australia.
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 millimetres in length, 150 mm (6 in) across the wings and 2–2.6 g in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox reaching a weight of 1.6 kg and having a wingspan of 1.7 m.
The subfamily Cynopterinae comprises 24 species of pteropodid bats distributed exclusively in South and Southeast Asia.
