Leptopelis Christyi
''Leptopelis christyi'', also known as the Christy's tree frog or Christy's forest treefrog, is a species of frog in the family Arthroleptidae. It is known with confidence from eastern and northeastern Democratic Republic of Congo, southern and western Uganda, and northwestern Tanzania. It is likely to occur in Burundi and Rwanda, possibly ranging further in East Africa. There is an isolated population in Cameroon and Gabon that might represent a distinct species. The specific name ''christyi'' honours Dr. Cuthbert Christy, a British army doctor who collected the holotype. Description Adult males measure and adult females in snout–vent length. The tympanum is large, about half to three-fourths of the diameter of the eye. The dorsum often bears a dark, forward-pointing triangle. Most individuals have a light, irregular lateral line. Also a green colour phase might be present. Males have pectoral glands. The male advertisement call is a single, rather tonal clack. Habitat an ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Amphibians Described In 1912
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 ...

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 ...

Leptopelis
''Leptopelis'' is a genus of frogs in the family Arthroleptidae. They are found throughout Sub-Saharan Africa, excluding Madagascar. It is placed in monotypic subfamily Leptopelinae, although this subfamily is not always recognized. They have a number of common names, including forest treefrogs, tree frogs, leaf-frogs, and big-eyed frogs. Description ''Leptopelis'' are mostly medium-sized frogs (snout–vent length ), but ''Leptopelis palmatus'' can reach . Tympanum is present. Most species have expended digit tips. Ecology ''Leptopelis'' are mainly arboreal, but some species, especially in more arid areas, are terrestrial or even subfossorial. Breeding typically starts with the heavy rains in the beginning of the wet season. Eggs may be deposited either in water or in/on the ground. Development includes a free-living tadpole stage, with a possible exception of '' Leptopelis brevirostris'', whose large eggs suggest that development could be direct. Males typically call in bushe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garamba National Park
Garamba National Park is a nearly national park in north-eastern Democratic Republic of the Congo. It is among Africa's oldest parks, and was designated a World Heritage Site by UNESCO in 1980 for its protection of critical habitat for northern white rhinoceroses, elephants, hippopotamuses, and giraffes. Garamba has been managed by African Parks in partnership with the Institut Congolais pour la Conservation de la Nature (ICCN), since 2005. Overview Garamba National Park was established in 1938 and covers an area of a in northeastern Democratic Republic of the Congo. It is bounded by Gangala-na-Bodio Hunting Reserve on the west, south, and east, and borders South Sudan on the north and northeast. It is part of the Sudano– Guinean savanna zone. The park is one of Africa's oldest protected areas. It lies in the transition zone between two centres of endemism: Guinea-Congolian and Guinean-Sudanese savanna. These two biogeographic zones support a variety of wildlife, which hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kibale National Park
Kibale Forest National Park is a national park in western Uganda, protecting moist evergreen rainforest. It is in size and ranges between and in elevation. Despite encompassing primarily moist evergreen forest, it contains a diverse array of landscapes.McGrew, William, ''et al''. ''Great Ape Societies''. Cambridge University Press, 1996. Print. Kibale is one of the last remaining expanses to contain both lowland and montane forests. In eastern Africa, it sustains the last significant expanse of pre-montane forest. The park was gazetted in 1932 and formally established in 1993 to protect a large area of forest previously managed as a logged forest reserve. The park forms a continuous forest with Queen Elizabeth National Park. This adjoining of the parks creates a wildlife corridor. It is an important ecotourism and safari destination, well-known for its population of habituated chimpanzees and twelve other species of primates. It is also the location of the Makerere University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...
