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, officially the Democratic Republic of São Tomé and Príncipe, is an 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 northwestern coast of Gabon. With a population of 201,800 (2018 official estimate),Instituto Nacional de Estadística de São Tomé e Príncipe, as of 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 Portuguese explorers João de Santarém and Pedro Escobar became the first Europeans to discover them in 1470. Gradually colonized and settled throughout the 16th century, they collectively served as a vital commercial and trade centre for the Atlantic slave trade. The rich volcanic soil and proximity to the equator made São Tomé and Príncipe ideal for sugar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Guinea (English)
The Gulf of Guinea (French: ''Golfe de Guinée''; Spanish: ''Golfo de Guinea''; Portuguese: ''Golfo da Guiné'') is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. Null Island, defined as 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 "Guinea" is thought to have originated from a local name for an area in the region, although the specifics are disputed. Bovill (1995) gives a thorough description: The name "Guinea" was also previously applied to the south coast of West Africa (north of the Gulf of Guinea), which became known as "Upper Guinea", and to the west coast of Southern Africa (to the east), which became known as "Lower Guinea". Today, the word "Guinea" is found in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameroon Line
The Cameroon line (, , ) is a long chain of volcanoes that includes islands in the Gulf of Guinea and mountains on the African mainland, from Mount Cameroon on the coast towards Lake Chad on the northeast. They form a natural border between eastern Nigeria and the West Region of Cameroon. The islands, which span the equator, have tropical climates and are home to many unique plant and bird species. The mainland mountain regions are much cooler than the surrounding lowlands, and also contain unique and ecologically important environments. The Cameroon volcanic line is geologically unusual in extending through both the ocean and the continental crust. Various hypotheses have been advanced by different geologists to explain the line. Geography In the Gulf of Guinea, the Cameroon line consists of six offshore volcanic swells that have formed islands or seamounts. From the southwest to the northeast the island groups are Annobón (or Pagalu), São Tomé, Príncipe and Bioko. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 shallow intrusive or 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. It has an unusually high (12% or more) Na2O + K2O content, defining its position in the TAS classification of igneous rocks. Its coarse grained (phaneritic) 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 su ...

Epiphytes
An epiphyte is a plant or plant-like organism that grows on the surface of another 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. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leptopelis Palmatus
''Leptopelis'' is a genus of frogs in the family Arthroleptidae. They are found throughout Sub-Saharan Africa, excluding Madagascar. It is placed in monotypic subfamily Leptopelinae, although this subfamily is not always recognized. They have a number of common names, including forest treefrogs, tree frogs, leaf-frogs, and big-eyed frogs. Description ''Leptopelis'' are mostly medium-sized frogs (snout–vent length ), but '' Leptopelis palmatus'' can reach . Tympanum is present. Most species have expended digit tips. Ecology ''Leptopelis'' are mainly arboreal, but some species, especially in more arid areas, are terrestrial or even subfossorial. Breeding typically starts with the heavy rains in the beginning of the wet season. Eggs may be deposited either in water or in/on the ground. Development includes a free-living tadpole stage, with a possible exception of '' Leptopelis brevirostris'', whose large eggs suggest that development could be direct. Males typically call in bush ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
