Ptychadena Tournieri
''Ptychadena tournieri'' is a species of frog in the family Ptychadenidae. It is a widespread species in West Africa and found in Senegal, Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, and Ivory Coast, as well as in Togo and Benin; it is assumed to occur in Ghana and southeastern Burkina Faso, although it has not been recorded there. On the other hand, some records may refer to other species; the Amphibian Species of the World excludes Gambia and Togo from the distribution. Common names Liberia grassland frog and Tournier's rocket frog are sometimes used. Etymology The Specific name (zoology), specific name ''tournieri'' refers to Jean-Luc Tournier, who was director of the ''Institut Français d’Afrique Noire'' in Abidjan (now Institut Fondamental d'Afrique Noire). Description Adult males measure and females in snout–vent length. The webbing in feet leaves one Phalanx bone, phalanx of toe V free (two in ''P. pujoli''). The head is slightly longer than wide and with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Marius René Guibé
Jean Marius René Guibé was a French naturalist, especially a herpetologist. He was born on 18 February 1910 in Paris and died on 4 May 1999 in Caen.

Amphibian Species Of The World
''Amphibian Species of the World 6.1: An Online Reference'' (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians, which scientists first described each species and what year, and the animal's known range. The American Museum of Natural History hosts ''Amphibian Species of the World''. As of 2019, it contained more than 8000 species. History The Association of Systematics Collections (ASC) started this project in 1978 because the Convention on Trade in Endangered Species of Fauna and Flora (CITES) needed a database for animals. (The ASC later changed its name to Natural Science Collections Alliance.) The ASC's Stephen R. Edwards wrote ''Mammal Species of the World'' first and started ''Amphibian Species of the World'' second. Edwards decided to write about living amphibians because Richard G. Zweifel had just composed a large list of amphibian names and because experts from the University of Kansas were available to assist him. Darrel ...

Taxa Named By Jean Marius René Guibé
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] |
Amphibians Of West Africa
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 ...

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 Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Medit .... 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.

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 ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Phalanx Bone
The phalanges (singular: ''phalanx'' ) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones. Structure The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two. The middle and far phalanges of the fifth toes are often fused together (symphalangism). The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abidjan
Abidjan ( , ; N'Ko script, N’ko: ߊߓߌߖߊ߲߬) is the economic capital of the Ivory Coast. As of the Demographics of Ivory Coast, 2021 census, Abidjan's population was 6.3 million, which is 21.5 percent of overall population of the country, making it the sixth most populous city proper in Africa, after Lagos, Cairo, Kinshasa, Dar es Salaam, and Johannesburg. A cultural crossroads of West Africa, Abidjan is characterised by a high level of industrialisation and urbanisation. It also is one of the most populous French-speaking cities in Africa. The city expanded quickly after the construction of a new wharf in 1931, followed by its designation as the capital city of the then-French colony in 1933. The completion of the Vridi Canal in 1951 enabled Abidjan to become an important sea port. Abidjan remained the capital of the Ivory Coast after its independence from France in 1960. In 1983, the city of Yamoussoukro was designated as the official political capital of Ivory Coast. Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
