Poyntonia
''Poyntonia'', is a monotypic frog genus in the family Pyxicephalidae. It was named after J.C. Poynton, a notable herpetologist who worked in southern Africa. ''Poyntonia paludicola,'' commonly known as the Montane Marsh frog, is the sole member of the genus. It is endemic to the Western Cape province, South Africa. Populations have been recorded in the Kogelberg, Hottentots-Holland, and Klein River mountains at the elevations of asl. Despite occurring as relatively fragmented populations across its range, it is locally abundant in suitable habitat and is presumably philopatric. It is possible that the separate populations represent cryptic species, but this has to be investigated. Description ''P. paludicola'' resemble bufonids due to their stout form and warty appearance. Adults attain a length of 27 - 30mm, with females being larger than males. The tympanum is not visible. Fingers have slight webbing. Toes are long without discs. Warts cover most of the body.

Pyxicephalidae
The Pyxicephalidae are a family of frogs currently found in sub-Saharan Africa. However, in the Eocene, the taxon '' Thaumastosaurus'' lived in Europe. Classification The Pyxicephalidae contain two subfamilies, with a total of 12 genera. This family was formerly considered part of the family Ranidae.

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

African Bullfrog
The African bullfrog (''Pyxicephalus adspersus'') is a species of frog in the family Pyxicephalidae. It is also known as the pixie frog due to its scientific name. It is found in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Tanzania, Uganda, Zambia, Zimbabwe, and possibly the Democratic Republic of the Congo. It has been extirpated from Eswatini. It has long been confused with the edible bullfrog (''P. edulis'') and species boundaries between them, including exact range limits, are not fully understood. Additionally, '' P. angusticeps'' of coastal East Africa only was revalidated as a separate species in 2013. The natural habitat of the African bullfrog is moist to dry savanna, subtropical to tropical dry shrubland, intermittent freshwater lakes, intermittent freshwater marshes, arable land, pastureland, canals, and flooded ditches. It is among the largest anurans on the planet, sixth only to the goliath frog, the helmeted water toad, the Lake Junin frog ...

Anthropogenic Effect
Human impact on the environment (or anthropogenic impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it wa ...

Benthic Zone
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertida ...

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hottentots Holland Nature Reserve
The Hottentots Holland Mountains are part of the Cape Fold Belt in the Western Cape, South Africa. The mountain range forms a barrier between the Cape Town metropolitan area and the southern Overberg coast. The range is primarily composed of Table Mountain Sandstone, and lies between the eastern Cape Town suburbs of Somerset West and Gordon's Bay to the west, and the Elgin valley to the east. Sir Lowry's Pass is the only crossing, in the form of the N2 motorway. The Steenbras Dam, one of Cape Town's main supply dams, is located in the Elgin valley south of the town of Grabouw due to the abundant rainfall normally experienced in the uplands of the catchment area. Pass The Gantouw (Eland Pass) ceased to be used by wagons on the 6th July 1830, when the new Sir Lowry's Pass road was opened. Wagons of the Great Trek beginning 1835 did not actually use the old pass, instead they used the new road. When previous migrants decided to leave the Cape Town area, or Cape Colony as it was th ...
