Grey Foam-nest Treefrog
The grey foam-nest tree frog (''Chiromantis xerampelina''), or southern foam-nest tree frog, is a species of frog in the family Rhacophoridae. They are found in southern Africa. Its natural habitats are subtropical or tropical dry forest, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical dry lowland grassland, subtropical or tropical seasonally wet or flooded lowland grassland, intermittent freshwater marshes, arable land, pastureland, rural gardens, urban areas, heavily degraded former forests, ponds, and canals and ditches. Grey foam-nest tree frogs are known for simultaneous polyandry, where female frogs have multiple mates on separate territories that guard the eggs and care for young. This behavior is owed to their external fertilization mechanism. During the mating process, the female frog produces a foam nest, typically on branches that hang above bodies of water, in order to keep her eggs mo ...

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he g ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Amphibians Of South 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 decline ...

Chiromantis Kelleri
''Chiromantis kelleri'' is a species of frog in the family Rhacophoridae. It is found in eastern and southern Ethiopia, northern Kenya, and Somalia; its range probably extends into South Sudan. The specific name ''kelleri'' honours who collected the type series. Common name Keller's foam-nest frog has been proposed for it. Description Males grow to a snout–vent length of and females to . The dorsum is rough and has usually grey and brown colouration, sometimes with darker markings. The throat is grey in males. The belly is darkened. The fingers and the toes are partially webbed and bear small terminal discs. The male advertisement call is a slow creak. Habitat and conservation ''Chiromantis kelleri'' occurs in arid savanna and shrubland. Breeding takes place in temporary pools and involves foam nests.

Chiromantis Petersii
''Chiromantis petersii'' is a species of frog in the family Rhacophoridae. It is found in Kenya and Tanzania and is broadly distributed in the inland areas of both countries. ''Chiromantis kelleri'' was previously considered subspecies of ''Chiromantis petersii'', but is currently recognized as a distinct species. These two species are sympatric in northern Kenya. Etymology and common names The specific name ''petersii'' honours Wilhelm Peters, German zoologist and traveller. Common names Peters' foam-nest treefrog, Peters' foam-nest frog, and central foam-nest tree frog have been proposed for it. Description Males grow to a snout–vent length of and females to . The dorsum is rough and has usually grey and brown colouration, sometimes with darker markings. The throat is pale and may have black speckles. The fingers and the toes are partially webbed and bear small terminal discs. The male advertisement call is a series of quiet creaks. Habitat and conservation ''Chiromantis ...

Aestivate
Aestivation ( la, aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. Fossil records suggest that aestivation may have evolved several hundred million years ago. Physiology Organisms that aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state.

Rhacophoridae
The Rhacophoridae are a family of frogs that occur in tropical sub-Saharan Africa, South India and Sri Lanka, Japan, northeastern India to eastern China and Taiwan, south through the Philippines and Greater Sundas, and Sulawesi. They are commonly known as shrub frogs, or more ambiguously as " moss frogs" or " bush frogs". Some Rhacophoridae are called "tree frogs". Among the most spectacular members of this family are numerous "flying frogs". Although a few groups are primarily terrestrial, rhacophorids are predominantly arboreal treefrogs. Mating frogs, while in amplexus, hold on to a branch, and beat their legs to form a foam. The eggs are laid in the foam and covered with seminal fluid before the foam hardens into a protective casing. In some species, this is done in a large group. The foam is laid above a water source so the tadpoles fall into the water once they hatch. The species within this family vary in size from . Like other arboreal frogs, they have toe discs, and thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
