Myotis Nimbaensis
The Nimba myotis (''Myotis nimbaensis''), also known as the orange-furred bat or Nimba Mountain bat, is a species of bat in the family Vespertilionidae. The species is endemic to the Nimba Mountains in Guinea, West Africa. It was discovered in 2018 and officially described in 2021 by a team of scientists from the American Museum of Natural History in partnership with a team from The University of Cameroon, which was led by American mammalogist Nancy Simmons. Description ''M. nimbaensis'' has orange fur with black dichromatic wing pigmentation. It lives in natural caves and adits (abandoned mine shafts) in the Nimba mountain range. The expedition of researchers went out searching for Lamotte's roundleaf bat Lamotte's roundleaf bat (''Hipposideros lamottei'') is a species of bat found only at Mount Nimba on the border of Côte d'Ivoire, Guinea and Liberia.

Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of West Africa
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saurop ...

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] |
Mouse-eared Bats
The mouse-eared bats or myotises are a diverse and widespread genus (''Myotis'') of bats within the family Vespertilionidae. The noun "''myotis''" itself is a New Latin construction, from the Greek language, Greek "''muós'' (meaning "mouse") and "''oûs''" (meaning ear), literally translating to "mouse-eared". Relationships ''Myotis'' has historically been included in the subfamily Vespertilioninae, but was classified in its own subfamily, Myotinae, by Nancy Simmons in 1998. In her 2005 classification in ''Mammal Species of the World'', Simmons listed the genera ''Cistugo'' and ''Lasionycteris'' in the Myotinae in addition to ''Myotis'' itself.Simmons, 2005, p. 499 However, molecular data indicate that ''Cistugo'' is distantly related to all other Vespertilionidae, so it was reclassified into its own family, the Cistugidae, and that ''Lasionycteris'' belongs in the Vespertilioninae.Roehrs et al., 2010 The genus ''Submyotodon'' has since been added to the subfamily, making it and ...

Myotis Welwitschii
Welwitsch's bat also known as Welwitsch's mouse-eared bat or Welwitsch's myotis (''Myotis welwitschii'') is a species of vesper bat native to Africa. Description Welwitsch's bat is a relatively large member of its genus, measuring about in length, and weighing . The body is chestnut brown, with off-white underparts, while the wing membranes are particularly distinctive, being reddish in colour with irregular dark brown to black spots. The face is pinkish, with a moderately long snout and large round, coppery-red ears. Distribution and habitat Welwitsch's bat is found through much of eastern and southern Africa. In the east, it is patchily distributed from the Free State in South Africa to Ethiopia in the north, while further west it is also found in Zambia, the southern Democratic Republic of the Congo, and central Angola. It has also been reported from a single locality in Guinea. Within this large region, the bat has been reported form a range of different habitats, but appea ...

Myotis Tricolor
The Cape hairy bat, also known as little brown bat, Temminck's mouse-eared bat, Cape myotis, tricoloured mouse-eared bat, Cape hairy myotis, Temminck's hairy bat and three-coloured bat (''Myotis tricolor'') is a species of vesper bat that is found in Sub-Saharan Africa. Description The Cape hairy bat is a diminutive bat which is very similar in appearance to the even more diminutive rufous mouse-eared bat. It has orangey to fufous fur on its back with slightly paler fur on the underparts, the fur is long, erect and his soft to the touch. Each hair is dark at its base and coppery-red towards the tips. it has relatively broad wings which are dark brown contrasting with the bright fur of the body.

Lamotte's Roundleaf Bat
Lamotte's roundleaf bat (''Hipposideros lamottei'') is a species of bat found only at Mount Nimba on the border of Côte d'Ivoire, Guinea and Liberia. It is critically endangered. Taxonomy It was described as a new species in 1984 by French zoologist André Brosset. He chose the species name ''lamottei'' after Dr. Maxime Lamotte, who was also a French zoologist. Its status as a species has been called into question, and some suggested that it might be synonymous with Noack's roundleaf bat, ''Hipposideros ruber''. While its mitochondrial gene for cytochrome b may only differ from that of ''H. ruber'' by only 6%, a 2013 study found that it was morphologically distinct from it. Based on its morphology, it is in the ''caffer/ruber'' species complex of its genus. Other species in this complex include: * Sundevall's roundleaf bat, ''H. caffer'' * Noack's roundleaf bat, ''H. ruber'' *'' H. tephrus'' Based on genetic analysis, it has been hypothesized that Lamotte's roundleaf bat has ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
