Population Biology
The term population biology has been used with different meanings. In 1971 Edward O. Wilson ''et al''. used the term in the sense of applying mathematical models to population genetics, community ecology, and population dynamics. Alan Hastings used the term in 1997 as the title of his book on the mathematics used in population dynamics. The name was also used for a course given at UC Davis in the late 2010s, which describes it as an interdisciplinary field combining the areas of ecology and evolutionary biology. The course includes mathematics, statistics, ecology, genetics, and systematics. Numerous types of organisms are studied. The journal ''Theoretical Population Biology ''Theoretical Population Biology'' is a peer-reviewed scientific journal covering research on theoretical aspects population biology in its widest sense, including mathematical modelling of populations, ecology, evolution, genetics, demography, ...'' is published.

Bonin Flying Fox
The Bonin flying fox, Bonin fruit bat (''Pteropus pselaphon''), or in Japanese is a species of flying fox in the family Pteropodidae. It is endemic to four islands (Chichijima, Hahajima, North Iwo Jima, and South Iwo Jima) in Ogasawara Islands, Japan. Its natural habitat is subtropical forests. It is threatened by habitat loss. Etymology The Bonin flying fox was described by British naturalist George Tradescant Lay in 1829. He gave it the species name ''pselaphon'' as a reference to "the habit of feeling instead of seeing its way in the day time." ''Pselaphon'' is a New Latin word ."Pselaphus." Merriam-Webster.com. Merriam-Webster, n.d. Web. 3 September 2017. Taxonomy As the Pteropus genus is quite speciose, it is traditionally divided into closely related species groups, identified based on morphology. Traditionally, the Bonin flying fox has been the identifier of the ''pselaphon'' species group, of which there are several other members: *the extinct large Palau flying fox * ...

Rodrigues Flying Fox
The Rodrigues flying fox or Rodrigues fruit bat (''Pteropus rodricensis'') is a species of bat in the family Pteropodidae, the flying foxes or fruit bats. It is endemic to Rodrigues, an island in the Indian Ocean belonging to Mauritius. Its natural habitat is tropical lowland forests. The bats are sociable, roost in large groups during the day and feed at night, squeezing the juice and flesh out of fruits. They are hunted by humans for food and their numbers have been dwindling, and the International Union for Conservation of Nature has rated the species as being "endangered". In an effort to preserve them from extinction, some bats have been caught and are being bred in various zoos around the world. Ecology It is a sociable species which lives in large groups. It can reach 350 g in weight and has a wingspan of 90 cm. At night, the bats forage in dry woodland for fruit of various trees, such as tamarinds, rose-apples, mangoes, palms, and figs.

Nyctalus Azoreum
The Azores noctule (''Nyctalus azoreum'') is a species of bat found in the dry forests of the Azores. It is the only species of mammal endemic to the Azores. It has been recorded on most of the islands of the Azores, and remains common on some but is rare on others. Its numbers are threatened due to habitat loss caused by humans, and the remaining populations are quite fragmented. It is known to roost in hollowed-out trees, buildings, and caves. The species is related to the widespread lesser noctule, and in the past was treated as a subspecies of that species. Genetic studies have found that it originated recently from lesser noctules which colonised the Azores, and has low levels of genetic divergence from its parent species. It nevertheless is much smaller than the lesser noctule and weighs less, has darker fur and has a different frequency of echolocation calls (about 4–5 Hz higher), and is usually treated as a separate species. As opposed to other bats, the Azores n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Caledonia Wattled Bat
The New Caledonian wattled bat (''Chalinolobus neocaledonicus'') is a species of vesper bat, family Vespertilionidae. It is found only in New Caledonia. Taxonomy The New Caledonia wattled bat was first described by Swiss naturalist Pierre Revilliod in 1914. It was formerly considered a subspecies of Gould's wattled bat (''Chalinolobus gouldii''), but evidence for synonymy is weak. Its species name "''neocaledonicus''" comes from Ancient Greek '' néos'' meaning "new" and the New Latin rendering of "Caledonia," ''caledonicus''; the species name refers to New Caledonia where this species is found. Description It is a small species of bat, with a head and body length of only . Its forearm is long, and its tail is long. Its ears are relatively long, at Its dental formula is , for a total of 32 teeth. Range and habitat It is one of nine species of bat found in New Caledonia. It is among the three species of bat endemic to the territory. Conservation It is considered endangered by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Livingstone's Fruit Bat
Livingstone's fruit bat (''Pteropus livingstonii''), also called the Comoro flying fox, is a megabat in the genus ''Pteropus''. It is an Old World fruit bat found only in the Anjouan and Mohéli islands in the Union of the Comoros in the western Indian Ocean. It is the largest and rarest bat of all Comorian species. Its preferred habitat is montane forest above on Mohéli and above on Anjouan, the destruction of which is a major threat to the bat population. As of 2003, the total population was estimated at 1,200 individuals. Other threats to the bats' survival include storms, hunting, and their struggles to readapt to new habitats. The black-bearded flying fox is believed to be one of the closest relatives of Livingstone's fruit bats, but experts differ as to whether or not these species belong to the same species group. No subspecies have been recognized. Physical appearance Livingstone's fruit bats are mostly black in colour, with a scattering of golden or tawny hairs ove ...

Canary Big-eared Bat
The Canary long-eared bat (''Plecotus teneriffae''), also known as the Canary big-eared bat or Tenerife long-eared bat, is a species of vesper bat endemic to the Canary Islands. According to the IUCN, it is vulnerable to the risk of extinction. The species is primarily found in woodland habitat at elevations between 100 and 2300 m. It feeds mainly on moths. Roosting sites include caves, lava tubes and abandoned buildings. Taxonomy and etymology It was described as a new species in 1907 by British mammalogist Gerald Edwin Hamilton Barrett-Hamilton. He described it based on specimens in the British Museum of Natural History. The holotype had been collected by R. Gomez in April 1887 near the town of La Orotava. "R. Gomez" was likely Ramon Gomez, a local pharmacist who traded in medicines, old coins, and biological specimens from the Canary Islands. Its species name "''teneriffae''" is derived from Tenerife, which is one of the islands of the Canary Islands and the place where t ...
