Cardioglossa Pulchra
''Cardioglossa pulchra'' is a species of frog in the family Arthroleptidae. It is found in the Cameroon Range in western Cameroon (excluding Mount Cameroon) and in the Obudu Plateau in adjacent eastern Nigeria. Common name black long-fingered frog has been coined for it. Description Males measure and females in snout–vent length. Males have extremely long third fingers and spines in the fingers and in the groin; females lack these characteristics (though no female specimens of this particular species were inspected). Dorsal markings, typical for the genus ''Cardioglossa'', are fused to a broad black stripe that extends over the entire dorsum. The white line running under the tympanum is absent. The tadpoles have a depressed, elliptical body and a long tail with broadly rounded tip. The largest specimen (Gosner stage 29) measures in total length, most of which is tail: body length is only .

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 ...

Taxa Named By Arne Schiøtz
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1963
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), 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 ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Fauna Of Nigeria
The wildlife of Nigeria consists of the flora and fauna of this country in West Africa. Nigeria has a wide variety of habitats, ranging from mangrove swamps and tropical rainforest to savanna with scattered clumps of trees. About 290 mammal species and 940 bird species have been recorded in the country. Geography Nigeria is a large country in West Africa just north of the equator. It is bounded by Benin to the west, Niger to the north, Cameroon to the east and the Atlantic Ocean to the south. The country consists of several large plateaus separated by the valleys of the two major rivers, the Niger and the Benue, and their tributaries. These converge inland and flow into the Gulf of Guinea through a network of creeks and branches which form the extensive Niger Delta. Other rivers flow directly to the sea further west, with many smaller rivers being seasonal. The highest mountain is Chappal Waddi () on the Mambilla Plateau in the southeast of the country near the border with Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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" ...

Cardioglossa
''Cardioglossa'' is a genus of frogs in the family Arthroleptidae known as long-fingered frogs. They are native to western and central Africa, with the greatest species richness in Cameroon. They are found near streams in lowland and mountain forests, but also occur in other highland habitats near streams at up to in altitude. These are small frogs with a snout-to-vent length of . Some of the more localized species are threatened. Species There are 19 species of ''Cardioglossa'': *''Cardioglossa alsco ''Cardioglossa alsco'' is a species of frog in the family Arthroleptidae.

Cross River National Park
The Cross River National Park is a national park of Nigeria, located in Cross River State, Nigeria. There are two separate sections, Okwangwo (established 1991) and Oban (established 1988). The park has a total area of about 4,000 km2, most of which consists of primary moist tropical rainforests in the North and Central parts, with mangrove swamps on the coastal zones. Parts of the park belong to the Guinea-Congolian region, with a closed canopy and scattered emergent trees reaching 40 or 50 meters in height. Cross River National Park borders Korup National Park in Cameroon and is the largest rain forest area in Nigeria. It is also a hotspot for biodiversity.Fitz, J., Adenle, A. A., & Speranza, C. I.

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthroleptidae
The Arthroleptidae are a family (biology), family of frogs found in sub-Saharan Africa. This group includes African treefrogs in the genus ''Leptopelis'' along with the terrestrial breeding squeakers ''Arthroleptis'', and several genera restricted to the Guinean forests of central and west Africa, such as the hairy frog ''(Trichobatrachus)''. Taxonomy This family is the phylogenetic sister group of reed frogs, the Hyperoliidae, which together form the lineage Laurentobatrachia, a name that commemorates work on African frogs by the Argentine herpetologist Raymond Laurent. This group is further nested within the Afrobatrachia, an ancient African endemic lineage that includes the Brevicipitidae and Hemisotidae. The Arthroleptidae are separated, based on phylogenetic analyses, into three deeply divergent and dissimilar subfamilies: Arthroleptinae, Astylosterninae, and Leptopelinae. Some consider these to be separate families, while others do not recognize any subfamilies, in particul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
