Astylosternus Schioetzi
''Astylosternus schioetzi'' is a species of frog in the family Arthroleptidae. It is endemic to south-western Cameroon and is only known from two areas near Edéa, Apouh and Koupongo, separated by the Sanaga River. The specific name ''schioetzi'' honours , a Danish herpetologist who has worked extensively on African tree frogs. Common name Apouh night frog has been coined for this species (Apouh is the type locality). ''Astylosternus schioetzi'' occurs in lowland forests, in and near flowing water. Breeding takes place in small streams, including very small, superficial streams in marshy depressions. It is a rare species threatened by habitat loss and degradation caused clearance for agricultural land, human settlements, and logging. It might occur in the Douala Edéa Wildlife Reserve Douala is the largest city in Cameroon and its economic capital. It is also the capital of Cameroon's Littoral Region. It was home to Central Africa's largest port, now being replaced by Kribi ... [...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] |
Endemic
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Cameroon
Cameroon, officially the Republic of Cameroon, is a country in Central Africa. It shares boundaries with Nigeria to the west and north, Chad to the northeast, the Central African Republic to the east, and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea, and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Cameroon's population of nearly 31 million people speak 250 native languages, in addition to the national tongues of English and French, or both. Early inhabitants of the territory included the Sao civilisation around Lake Chad and the Baka people (Cameroon and Gabon), Baka hunter-gatherers in the southeastern rainforest. Portuguese discoveries, Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''C ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) 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". Etymology 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 ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

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] |

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" ...

Amphibians Of Cameroon
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living 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, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this. Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
