Amnirana Lepus
''Amnirana lepus'' is a species of frog in the family Ranidae. It is found in Cameroon, Equatorial Guinea, Gabon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, and northern Angola. Common names Andersson's Cameroon frog, Andersson's white-lipped frog, and jumping white-lipped frog have been proposed for it. Description Males grow to a snout–vent length of and females to . The body is elongated and the snout is moderately pointed, rounded in lateral view. The tympanum is relatively large. The legs are slender and long. The toes are fully webbed. The finger and the toe tips bear discs. The upper surfaces are dark to bronze-brown, possibly with darker spots. The flanks turn to pale green in their lower part and have some dark patterning. The venter is pale green. Males do not have an external vocal sac, but they do have short oval glands in their upper arms and nuptial pads on the thumbs. The male advertisement call is a quiet, high-frequenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lars Gabriel Andersson
Lars Gabriel Andersson (22 February 1868 – 13 February 1951) was a Swedish schoolteacher and herpetologist. He studied at Uppsala University and earned his PhD in 1909. During his long career he taught classes at several schools in and near Stockholm. In 1894–95 and from 1897 to 1902 he worked as an assistant in the vertebrate department at the Naturhistoriska riksmuseet in Stockholm. Taxa With zoologist Einar Lönnberg he described the following herpetological species: * ''Aipysurus tenuis'', 1913 * '' Atractaspis engdahli'', 1913 * ''Eulamprus brachyosoma'', 1915. * '' Eulamprus tympanum'', 1915 * '' Gastrotheca microdiscus'', (Andersson in Lönnberg and Andersson, 1910). * ''Glaphyromorphus mjobergi'', 1915 * ''Strophurus taeniatus'', 1913. On his own, he described: * '' Didynamipus sjostedti'', 1903 Works by Andersson that have been published in English * "Catalogue of Linnean type-specimens of snakes in the Royal Museum in Stockholm", 1899. * "Catalogue of Linnean ...

Amphibians Of Angola
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Taxa Named By Lars Gabriel Andersson
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frogs Of Africa
The fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical realm. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife. Africa is home to many of the world's most famous fauna in human culture such as lions‚ rhinos‚ cheetahs‚ giraffes‚ antelope, hippos, leopards, zebras‚ and African elephants among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" tha ...

Fritz Nieden
Fritz Nieden (1883 – 1942) was a German zoologist who specialized in African herpetology. He worked as a zoologist at the ''Museum für Naturkunde'' in Berlin. His name is associated with Nieden's dwarf skink, '' Panaspis megalurus''. In 1911 he was the first to describe '' Callulina kreffti'', a species of frog, which until 2004 was the only known species of the genus ''Callulina''. The Sagala caecilian, ''Boulengerula niedeni'', is named after him. Selected writings *Die Amphibienfauna von Kamerun' (1908), Mitteilungen aus dem Zoologischen Museum in Berlin 3: 491–518 ("''Amphibian fauna of Cameroon''") *''Die Reptilien (außer den Schlangen) und Amphibien'', 1910 - Reptiles (other than snakes) and amphibians. *''Gymnophoina (Amphibia apoda)'', 1913 - Gymnophiona Caecilians (; ) are a group of limbless, vermiform or serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians. Caecilians are mo ...

Amnirana
''Amnirana'' is a genus of frogs in the family Ranidae, "true frogs". The genus is primarily found in Sub-Saharan Africa, but one species occurs in parts of southern and southeastern Asia. Some of the African species are widespread but contain undescribed cryptic diversity. Most (but not all) species have a white upper lip, and the genus is sometimes known as the white-lipped frogs. Taxonomy ''Amnirana'' was originally introduced as a subgenus of ''Rana''. It was often included in the then-diverse genus ''Hylarana'', until Oliver and colleagues revised the genus in 2015, delimiting ''Hylarana'' more narrowly and elevating ''Amnirana'' to genus rank. Within the genus, '' Amnirana nicobariensis'' appears to be the sister taxon of the African clade of species, but the data are inconclusive. With more data available to resolve possible non-molecular synapomorphies of the genus, ''A. nicobariensis'' might become recognized as a separate genus. A later study suggested it to be close ...
