Georg Johann Pfeffer
Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks. Pfeffer was born in Berlin. In 1887 he became curator of the , which was established in 1843 and destroyed during World War II. Pfeffer's published writings were mainly about cephalopods. The World Register of Marine Species database lists 133 marine Taxon, taxa named by Pfeffer When Pfeffer's name is listed as an authority for a taxon such as the land snail genus ''Lamellaxis'' Hermann Strebel, Strebel & Pfeffer, 1882, his name is ''not'' simply an orthography, orthographic error for the more commonly encountered molluscan authority Pfeiffer, i.e. Ludwig Karl Georg Pfeiffer, who lived 50 years earlier, from 1805 to 1877.

Gaston-François De Witte
Gaston-François de Witte (12 June 1897, in Antwerp – 1 June 1980, in Brussels) was a Belgian herpetologist who discovered and described at least 24 different species of reptiles. During his career, he was associated with the Royal Museum for Central Africa in Tervuren (from 1920) and the Museum of Natural Sciences in Brussels (from 1937). He is best known for his research of amphibians and reptiles found in the Belgian Congo, from where he collected thousands of specimens. While in central Africa, he also collected botanical specimens. Biography Gaston-François de Witte was the son of Henry de Witte and Jeanne della Faine de Leverghem, and the grandson of Jean de Witte. As a child, he already liked natural science. During his scholarship at the Bénédictins of the Abbaye de Maredsours, Gaston-François met the British zoologist George Albert Boulenger, who came to study fossils from Denée. They became friends and Boulenger encouraged de Witte to study reptiles. When the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. 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 (mathematics), 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 ...

Quilimane
Quelimane () is a seaport in Mozambique. It is the administrative capital of the Zambezia Province and the province's largest city, and stands from the mouth of the Rio dos Bons Sinais (or "River of the Good Signs"). The river was named when Vasco da Gama, on his way to India, reached it and saw "good signs" that he was on the right path. The town was the end point of David Livingstone's west-to-east crossing of south-central Africa in 1856. Portuguese is the official language of Mozambique, and many residents of the areas surrounding Quelimane speak Portuguese. The most common local language is Chuabo. Quelimane, along with much of Zambezia Province, is extremely prone to floods during Mozambique's rainy season. History Pre-colonial era The town originated as a Swahili trade centre, and then grew as a slave market of the Indian Ocean slave trade. Quelimane was founded by Muslim traders (see Kilwa Sultanate) and was one of the oldest towns in the region. Etymology The orig ...

Mozambique
Mozambique, officially the Republic of Mozambique, is a country located in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the south and southwest. The sovereign state is separated from the Comoros, Mayotte, and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and dialect. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of the Portuguese Empire, Portuguese, who began a gradual process of colonisation and settlement in 1505.

Ptychadena
''Ptychadena'' is a genus of frogs in the grassland frog family, Ptychadenidae. They are distributed in Sub-Saharan Africa, as well as nilotic Egypt. The common names of this genus are ridged frogs and grass frogs. This type of family have many different characteristics such as the species, '' Ptychadena neumanni'' who have long hindlimbs and a large ear drum compared to the '' Ptychadena erlangeri, for example.'' They also have a unique bone structure which is a fusion between the presacral vertebrae and sacrum The sacrum (: sacra or sacrums), in human anatomy, is a triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30. The sacrum situates at the upper, back part of the pelvic cavity, ....

Frogs Of Africa
The fauna of Africa are all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna are found in the Afro-tropical realm. Lying almost entirely within the tropics, and stretching equally north and south of the equator creates favorable conditions for variety and abundance of wildlife. Africa is home to many of the world's most recognizable fauna such as lions‚ rhinoceroses‚ cheetahs‚ giraffes‚ antelope, hippopotamuses, leopards, zebras‚ and 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" ...

Amphibians Of Mozambique
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this. Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Mozambique
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a la ...
