Hoplophryne
''Hoplophryne'' is a genus of microhylid frogs. The genus is endemic to mountain forests of Tanzania. They are also known as three-fingered frogs or African banana frogs (not to be confused with ''Afrixalus'', another African genus known as "banana frogs"). Species There are two species in this genus, both endangered: * '' Hoplophryne rogersi'' Barbour and Loveridge, 1928 * '' Hoplophryne uluguruensis'' Barbour and Loveridge, 1928 Description ''Hoplophryne'' are small frogs, reaching in snout–vent length (female ''H. rogersi''). Their distinctive characters is that male frogs have only three fingers: the thumb is reduced to a small bump or group of spines. Ecology and reproduction ''Hoplophryne'' can be found in leaf litter, under logs, and in bananas and bamboos. Reproduction takes place in phytotelma Phytotelma (plural phytotelmata) is a small water-filled cavity in a terrestrial plant.

Hoplophryne Rogersi
''Hoplophryne rogersi'', also known as the Tanzania banana frog, Usambara banana frog, Usambara blue-bellied frog, and Roger's three-fingered frog, is a species of frog in the family Microhylidae. It is endemic to north-eastern Tanzania and known from the Usambara, Magrotto, and Nguru Mountains of Tanga Region. The specific name ''rogersi'' honours F. W. Rogers, the custodian of the Amani Research Institute at the time of the describers' visit to Usambara. Description Males grow to and females to in snout–vent length. The body is stout. Males have only three fingers as the thumb is reduced to a stump with a sharp, protruding bone. No webbing is present. The dorsum is smooth with small spines; there are larger spines on the throat, lips, chest, and limbs. The dorsum is slate-blue to grey-brown.

Microhylidae
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family. Evolution A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the Cretaceous extinction event. The most recent common ancestor of the Microhylidae and their closest ranoid relatives is estimated to have lived 116 million years ago in Gondwana. Description As suggested by their name, microhylids are mostly small frogs. Many species are below in length, although some species are as large as . They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt.

The Biology Of The Amphibia (1931) (19759582984)
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic ...

Endemic Fauna Of Tanzania
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Sub-Saharan Africa
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phytotelma
Phytotelma (plural phytotelmata) is a small water-filled cavity in a terrestrial plant. The water accumulated within these plants may serve as the habitat for associated fauna and flora. A rich literature in German summarised by Thienemann (1954) developed many aspects of phytotelm biology. Reviews of the subject by Kitching (1971) and Maguire (1971) introduced the concept of phytotelmata to English-speaking readers. A multi-authored book edited by Frank and Lounibos (1983)Frank, J.H. and Lounibos, L.P. (1983) ''Phytotelmata: Terrestrial plants as hosts for aquatic insect communities'', Plexus Press. dealt in 11 chapters with classification of phytotelmata, and with phytotelmata provided by bamboo internodes, banana leaf axils, bromeliad leaf axils, ''Nepenthes'' pitchers, ''Sarracenia'' pitchers, tree holes, and ''Heliconia'' flower bracts and leaf rolls. A classification of phytotelmata by Kitching (2000) recognizes five principal types: bromeliad tanks, certain carnivor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Barbour
Thomas Barbour (August 19, 1884 – January 8, 1946) was an American herpetologist. From 1927 until 1946, he was director of the Harvard Museum of Comparative Zoology (MCZ) founded in 1859 by Louis Agassiz at Harvard University in Cambridge, Massachusetts. Life and career Barbour, the eldest of four brothers, was born in 1884 to Colonel William Barbour, and his wife, Julia Adelaide Sprague. Colonel Barbour was founder and president of The Linen Thread Company, Inc., a successful thread manufacturing enterprise having much business in the United States, Ireland, and Scotland. Although born on Martha's Vineyard, Massachusetts, where the family was spending the summer, Barbour grew up in Monmouth, New Jersey, where one of his younger brothers, William Warren Barbour, entered the political arena, eventually serving as U.S. Senator from New Jersey from 1931 to 1937 and again from 1938 to 1943. At age fifteen, Thomas Barbour was taken to visit Harvard University, which, entranced by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Loveridge
Arthur Loveridge (28 May 1891 – 16 February 1980) was a British biologist and herpetologist who wrote about animals in East Africa, particularly Tanzania, and New Guinea. He gave scientific names to several gecko species in the region. Arthur Loveridge was born in Penarth, and was interested in natural history from childhood. He gained experience with the National Museum of Wales and Manchester Museum before becoming the curator of the Nairobi Museum (now the National Museum of Kenya) in 1914. During WW1, he joined the East African Mounted Rifles, later returning to the museum to build up the collections. He then became an assistant game warden in Tanganyika. In 1924, he joined the Museum of Comparative Zoology in the grounds of Harvard University in Cambridge, Massachusetts, where he was the curator of herpetology. He returned to East Africa on several field trips and wrote many scientific papers before retiring from Harvard in 1957. He married Mary Victoria Sloan in 192 ...
