Nycteris Woodi
Wood's slit-faced bat (''Nycteris woodi'') is a species of slit-faced bat that lives in the dry savanna regions of Southern Africa. Its numbers are declining due to habitat loss from logging and farming, pesticide use, and the decline of baobab tree ''Adansonia'' is a genus made up of eight species of medium-to-large deciduous trees known as baobabs ( or ).

Knud Andersen (mammalogist)
Knud Christian Andersen (29 April 1867 in Frederiksberg – last seen alive June 1918 in England) was a Danish zoologist. His research focused on bats. Life and work Towards the end of the 19th century, Andersen first worked as an ornithologist and ran field studies on the Faroe Islands. In 1901 Ferdinand I awarded him an appointment at the Zoological Museum of Sofia. Due to his frustration with the working conditions, he gave up this position.Jon Fjeldså: ''Danske ornitologer langt fra hjemmet: fra P.W. Lund til international fuglebeskyttelse'' In: ''100-års festskrift'' Dansk Orn. Foren. Tidsskr. 100 (2006):S. 265-275 In 1904, he was hired by the British Museum to research bats in the Pacific, in South-East Asia and in Queensland. He was especially interested in the genus Flying Fox and Horseshoe bats, of which he described 15 new species. He published 13 scientific papers on the South-East Asian Horseshoe bats. His most famous work was his ''Catalogue of the Chiroptera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Southern Africa
Southern Africa is the southernmost subregion of the African continent, south of the Congo and Tanzania. The physical location is the large part of Africa to the south of the extensive Congo River basin. Southern Africa is home to a number of river systems; the Zambezi River being the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, the Zambezi River flows over the mighty Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist attraction for the region. Southern Africa includes both subtropical and temperate climates, with the Tropic of Capricorn running through the middle of the region, dividing it into its subtropical and temperate halves. Countries commonly included in Southern Africa include Angola, Botswana, the Comoros, Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namib ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Pesticide
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus ''Alternaria solani'' is used to combat the aquatic weed ''Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or a ...

Baobab Tree
''Adansonia'' is a genus made up of eight species of medium-to-large deciduous trees known as baobabs ( or ). They are placed in the Malvaceae family, subfamily Bombacoideae. They are native to Madagascar, mainland Africa, and Australia.Tropicos.org. Missouri Botanical Garden. 8 Jul 2020 http://www.tropicos.org The trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described ''Adansonia digitata''. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plantsAdrian Patrut et al.

Mammals Of South Africa
The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 849 species of bird and over 20,000 species of vascular plants. Geography South Africa is located in subtropical southern Africa, lying between 22°S and 35°S. It is bordered by Namibia, Botswana and Zimbabwe to the north, by Mozambique and Eswatini (Swaziland) to the northeast, by the Indian Ocean to the east and south, and the Atlantic Ocean to the west, the coastline extending for more than . The interior of the country consists of a large, nearly flat, plateau with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mammals Described In 1914
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 Sauropsida ...
