Pico Do Príncipe
Pico do Príncipe is a mountain on the island of Príncipe, the smaller of the two inhabited islands of São Tomé and Príncipe. The elevation of the mountain is , making it the highest peak on the island. The island is one of the volcanic swells that make up the Cameroon line of extinct and active volcanoes. Topology The mountain is the remains of a volcano that has been inactive for 15.7 million years. The volcanoes on this island were at first primarily basalt, but later phonolite intruded in their cores. The basalt has been deeply eroded, leaving spectacular towers of the harder phonolite rising almost vertically from the rainforest. The peak has only occasionally been explored, with the first expedition in 1929 having established a base on the top. A second trip was made in 1956, but could not make a serious botanical inventory due to poor weather. The 1999 trip found that the mountain rises from a heavily forested plateau with elevation . From there, a series of ridges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

São Tomé And Príncipe
São Tomé and Príncipe (; pt, São Tomé e Príncipe (); English: " Saint Thomas and Prince"), officially the Democratic Republic of São Tomé and Príncipe ( pt, República Democrática de São Tomé e Príncipe), is a Portuguese-speaking island country in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands of São Tomé and Príncipe, about apart and about off the north-western coast of Gabon. With a population of 201,800 (2018 official estimate),Instituto Nacional de Estadística de São Tomé e Príncipe, as at 13 May 2018. São Tomé and Príncipe is the second-smallest and second-least populous African sovereign state after Seychelles. The islands were uninhabited until their discovery by Portuguese explorers in the 15th century. Gradually colonized and settled throughout the 16th century, they collectively served as a vital commercial and trade centre for the Atlantic slave trade. The ri ...

Gulf Of Guinea (English)
The Gulf of Guinea is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. The intersection of the Equator and Prime Meridian (zero degrees latitude and longitude) is in the gulf. Among the many rivers that drain into the Gulf of Guinea are the Niger and the Volta. The coastline on the gulf includes the Bight of Benin and the Bight of Bonny. Name The origin of the name Guinea is thought to be an area in the region, although the specifics are disputed. Bovill (1995) gives a thorough description: The name " Guinea" was also applied to south coast of West Africa, north of the Gulf of Guinea, which became known as "Upper Guinea", and the west coast of Southern Africa, to the east, which became known as "Lower Guinea". The name "Guinea" is still attached to the names of three countries in Africa: Guinea, Guinea-Bissau, and Equatorial Guinea, as well as New Guinea in Melanesia. Geography The main river s ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Phonolite
Phonolite is an uncommon extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained). Phonolite is a variation of the igneous rock trachyte that contains nepheline or leucite rather than quartz. Its intrusive equivalent is nepheline syenite. Phonolite is typically fine grained and compact. The name ''phonolite'' comes from the Ancient Greek meaning "sounding stone" due to the metallic sound it produces if an unfractured plate is hit; hence, the English name ''clinkstone'' is given as a synonym. Formation Unusually, phonolite forms from magma with a relatively low silica content, generated by low degrees of partial melting (less than 10%) of highly aluminous rocks of the lower crust such as tonalite, monzonite and metamorphic rocks. Melting of such rocks to a very low degree promotes the liberation of aluminium, potassium, sodium and calcium by melting of f ...

Epiphytes
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leptopelis Palmatus
The palm forest tree frog (''Leptopelis palmatus'') is a species of frog in the family Arthroleptidae which is endemic to Príncipe island in São Tomé and Príncipe. Red tree frog '' Leptopelis rufus'' from the African mainland was for a long time included in this species, but is now considered a distinct species. Description The palm forest tree frog is a large species: females measure in snout–vent length. The tympanum is large and the feet are fully webbed. The colouring varies, but the dorsum is typically dark green to black, sometimes with many light spots giving the frog a marbled appearance. The ventrum is dark and has a granular surface. Compared to the red tree frog, this species has larger choanae (the apertures where the nasal passages join the throat), larger tympani and differences in skin texture. Habitat and conservation The natural habitats of palm forest tree frog are wet forests along the edges of creeks and streams to above sea level, possibly to 1000 m ...
