African Long-fingered Bat
The African long-fingered bat (''Miniopterus africanus'') is a species of vesper bat in the family Miniopteridae. It is found only in Kenya. It is found in subtropical or tropical moist montane forests. This species is often considered a synonym of '' Miniopterus inflatus''. The holotype was collected in October 1926 by A. M. Bailey. It was described as a new species in 1936 by Colin Campbell Sanborn. Description It is similar in appearance to the Natal long-fingered bat, but it is much larger. Its dorsal fur is light brown, with the bases of individual hairs darker than their tips. Its ventral fur is lighter than the dorsal fur, with individual hairs brown at the base and gray at the tip. Its forearm is long. The greatest length of the skull is long. Biology It is known to be infected with the parasite '' Polychromophilus melanipherus'', which helps support the hypothesis that Haemosporidiasina transitioned from avian hosts to bat hosts in a single evolutionary event. ...

Colin Campbell Sanborn
Colin Campbell Sanborn (1897–1962) was a US ecologist and biologist, employed as curator of birds and mammals at the Field Museum of Natural History in Chicago. His works include taxonomic revisions of the Chiroptera bat families, and he was recognised in the specific epithet of the broad-nosed bat ''Scotorepens sanborni''. In 1950, Sanborn received a request from the infamous murderer Nathan Leopold Nathan Freudenthal Leopold Jr. (November 19, 1904 – August 29, 1971) and Richard Albert Loeb (; June 11, 1905 – January 28, 1936), usually referred to collectively as Leopold and Loeb, were two wealthy students at the University of Chicago ..., asking for photo of the Kirtland's warblers that Leopold had donated to the museum as a young birder, years before his crime; Sanborn had to tell the Joliet prison inmate that the specimens had never been exhibited or photographed.

Polyomaviridae
''Polyomaviridae'' is a family of viruses whose natural host (biology), hosts are primarily mammals and birds. As of 2020, there are six recognized genera and 117 species, five of which are unassigned to a genus. 14 species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent. Most of these viruses are very common and typically asymptomatic in most human populations studied. BK virus is associated with nephropathy in renal transplant and non-renal solid organ transplant patients, JC virus with progressive multifocal leukoencephalopathy, and Merkel cell virus with Merkel cell cancer. Structure and genome Polyomaviruses are viral envelope, non-enveloped double-stranded DNA viruses with circular genomes of around 5000 base pairs. The genome is packaged in a viral capsid of about 40-50 nanometers in diameter, which is icosahedral in shape (T=7 symmetry). The capsid is composed of 72 pentameric capsomeres of a protein ca ...

Bats Of Africa
Bats are mammals of the 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, 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 in length, across the wings and in mass. The largest bats are the 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 echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochirop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Population Growth
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. World human population has been growing since the end of the Black Death, around the year 1350. A mix of technological advancement that improved agricultural productivity and sanitation and medical advancement that reduced mortality increased population growth. In some geographies, this has slowed through the process called the demographic tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983).

Addis Ababa
Addis Ababa (; am, አዲስ አበባ, , new flower ; also known as , lit. "natural spring" in Oromo), is the capital and largest city of Ethiopia. It is also served as major administrative center of the Oromia Region. In the 2007 census, the city's population was estimated to be 2,739,551 inhabitants. Addis Ababa is a highly developed and important cultural, artistic, financial and administrative centre of Ethiopia. Addis Ababa was portrayed in the 15th century as a fortified location called "Barara" that housed the emperors of Ethiopia at the time. Prior to Emperor Dawit II, Barara was completely destroyed during the Ethiopian–Adal War and Oromo expansions. The founding history of Addis Ababa dates back in late 19th-century by Menelik II, Negus of Shewa, in 1886 after finding Mount Entoto unpleasant two years prior. At the time, the city was a resort town; its large mineral spring abundance attracted nobilities of the empire, led them to establish permanent settlement ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Miniopterus
''Miniopterus'', known as the bent-winged or long winged bats, is the sole genus of the family Miniopteridae. They are small flying insectivorous mammals, micro-bats of the order Chiroptera, with wings over twice the length of the body. The genus had been placed in its own subfamily among the vespertilionid bats, as Miniopterinae, but is now classified as its own family. Taxonomy The genus was erected in 1837 by Charles L. Bonaparte. In the first systematic revision of the genus, published in a monograph of ''Miniopterus'' in 1858 by Robert F. Tomes, the author reallocated specimens and described new taxa. A new systematic arrangement was produced in an extensive study of poorly known chiropterans of the Indo-Austral region by James E. Hill in 1985, the greater resolution of the genus being determined by the British Museum of Natural History's acquisition of new series of specimens collected in Fiji, the New Hebrides and New Caledonia and the extensive collection made in New G ...

Vesper Bat
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus ''Vespertilio'', which takes its name from a word for bat, ', derived from the Latin term ' meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds". (The term "evening bat" also often refers more specifically to one of the species, '' Nycticeius humer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
