Nycteris Intermedia
The intermediate slit-faced bat (''Nycteris intermedia'') is a species of slit-faced bat living in forest and savanna regions of west and central Africa. It is easily confused with ''Nycteris arge'' and '' Nycteris nana''. It is broadly distributed, but is classified as near-threatened because of the threat of predicted habitat loss. It is much more restricted to true rainforest Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire.

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ...

IUCN
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 ...

Slit-faced Bat
''Nycteris'' comprises a genus of bats commonly called slit-faced or hollow-faced bats. They are grouped in the family Nycteridae. The bats are found in East Malaysia, Indonesia, and many parts of Africa. Description They are small bats, from in body length, and with grey, brown, or reddish fur. The skull is distinguished by a characteristic interorbital concavity, externally connected to a long slit that runs down the centre of their faces from between the eyes to the nostrils, and probably assists in echolocation. They have large ears, and a complex nose-leaf. Their tails end in a T-shape, formed from cartilage, a unique feature among mammals. Their dental formula is: Nycterids have a reduction of the hand phalanges: the 2nd digit has only metacarpus, and the 3rd only two phalanges. The pectoral girdle has parallel features to birds. The sternum is strongly developed and the mesosternum has a keel. Habitat and biology Slit-faced bats inhabit rainforests and savanna, and r ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Nycteris Arge
Bate's slit-faced bat (''Nycteris arge'') is a species of slit-faced bat frequently confused with '' Nycteris major''. It is broadly distributed and common, living throughout many parts of Africa in forests and savannas. It was described as a new species in 1903 by British zoologist Oldfield Thomas. The holotype had been collected from Cameroon by George Latimer Bates. Description Bates's slit-faced bat, as the common name suggests, has a "deep median furrow" down its face. Its ears are large and rounded. Its dental formula is for a total of 32 teeth. It has a particularly large brain for an insectivorous bat species. Range and status It is found throughout Central and West Africa, including Angola, Benin, Burundi, Cameroon, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Kenya, Liberia, Nigeria, Rwanda, Sierra Leone, South Sudan, Tanzania Tanzania (; ), officially the United Republic of Tanzania ( sw, Jam ...

Nycteris Nana
The dwarf slit-faced bat (''Nycteris nana'') is a species of slit-faced bat living in forest and savanna regions of Central Africa. Two subspecies have been identified: ''N. n. nana'' and ''N. n. tristis''. The bat's range goes from Côte d'Ivoire and Ghana in the west, to Cameroon and the Democratic Republic of the Congo, from Rwanda and Burundi to Uganda and western Kenya, and to the south it ranges as far south as northern Angola. It is generally a lowland species. Its habitat has been recorded from both dry and moist lowland forest, gallery forest, and moist savanna A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

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 ...
