Pico De São Tomé
Pico de São Tomé is the highest mountain in São Tomé and Príncipe at elevation. It lies just west of the centre of São Tomé Island, in the Parque Natural Obô de São Tomé and in the Lembá District. The second highest point, Pico de Ana Chaves (), lies about to its south east. The town Santa Catarina is to the west. Description The entire island of São Tomé is a massive shield volcano which rises from the floor of the Atlantic Ocean, over below sea level. It formed along the Cameroon line, a linear rift zone extending from Cameroon southwest into the Atlantic Ocean. Most of the lava erupted on São Tomé over the last million years has been basalt. The most recent activity was about 36,000 years ago. On old maps of São Tomé and Príncipe, the mountain is named "Pico Gago Coutinho", after Portuguese naval officer Carlos Viegas Gago Coutinho (1869–1959) who, together with Sacadura Cabral (1881–1924), was the first to cross the South Atlantic Ocean by air. ...

Ana Chaves Bay
Ana Chaves Bay () is a bay on the northeast coast of São Tomé Island in São Tomé and Príncipe. The capital city of São Tomé and its port are situated by the bay. It stretches from the Ponta Oque del Rei in the north to Ponta São Sebastião in the south. Forte de São Sebastião, now part of São Sebastião Museum, occupies Ponta São Sebastião. The port of São Tomé was built at the end of the 1950sInformação geral Enaport on reclaimed land that extends north of Ponta São Sebastião; there is a 200 m quay at its north end, with a depth of 3 metres alongside. It is the main port of the country for solid goods; the port of Neves is the main point of entry for liquid fuels. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrocarpus Mannii
''Afrocarpus'' is a genus of conifer of the family Podocarpaceae. Five species are recognized. They are evergreen trees native to Africa. ''Afrocarpus'' was designated a genus in 1989, when several species formerly classified in ''Podocarpus'' and ''Nageia'' were reclassified.Christopher N. Page. 1989. "New and maintained genera in the conifer families Podocarpaceae and Pinaceae". ''Notes of the Royal Botanical Garden Edinburgh'' 45(2): 377-395. Taxonomy ''Afrocarpus'' was originally erected in 1948 as a section of the genus ''Podocarpus'', following a review of the latter by botanists John Theodore Buchholz and Netta Elizabeth Gray. It was raised to genus status by Christopher Nigel Page in 1989, a move well supported by more recent studies. In a 2009 treatment of the genus, only two species were recognized; ''A. dawei'', ''A. gracilior'', and ''A. usambarensis'' were sunk into ''A. falcatus''. The reason for this merger was that "variation across the group appears to be essen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fern
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaf, leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled Fiddlehead fern, fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae (plant), Polypodiidae) and eusporangiate ferns, the latter group including horsetails, Psilotaceae, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Forest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest, is a generally tropical or subtropical, evergreen, Montane forest, montane, Tropical and subtropical moist broadleaf forests, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the mountain pass, saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity-rich ecosystems in the world, with a large number of species directly or indirectly depending on them. Other moss forests include black spruce/feathermoss Climax community, climax forest, with a moderately dense canopy and a forest fl ...

Afromontane
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanzani ...

Epiphyte
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] |
Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genus of the vanilla plant), the type genus '' Orchis'', and many commonly cultivated plants such as '' Phalaenopsis'' and '' Cattleya''. Moreover, since the introduction of tropical species into cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theobroma Cacao
''Theobroma cacao'' (cacao tree or cocoa tree) is a small ( tall) evergreen tree in the Malvaceae family. Its seedscocoa beansare used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. Although the tree is native to the tropics of the Americas, the largest producer of cocoa beans in 2022 was Ivory Coast. The plant's leaf, leaves are alternate, entire, unlobed, long and broad. Description Flowers The flowers are produced in clusters directly on the Trunk (botany), trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink Calyx (botany), calyx. The floral formula, used to represent the structure of a flower using numbers, is ✶ K5 C5 A(5°+52) (5). While many of the world's flowers are pollinated by bees (Hymenoptera) or Butterfly, butterflies/moths (Lepidoptera), cacao flowers are pollinated by tiny flies, ''Forcipomyia'' biting midges. Using the natural pollinator ''Forcipomyia'' midges produced more fruit tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffee
Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes. Typically served hot, coffee has the highest sales in the world market for hot drinks. Coffee production begins when the seeds from coffee cherries (the '' Coffea'' plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Aerial Crossing Of The South Atlantic
The first aerial crossing of the South Atlantic was made by the Portuguese naval aviators Gago Coutinho and Sacadura Cabral in 1922, to mark the centennial of Brazil's independence. Coutinho and Cabral flew in stages from Lisbon, Portugal, to Rio de Janeiro, Brazil, using three different Fairey III biplanes, and covered a distance of between 30 March and 17 June. Although the North Atlantic had already been traversed in a non-stop flight by John Alcock and Arthur Brown in 1919, Coutinho and Cabral's flight remains notable as a milestone in transatlantic aviation, and for its use of new technologies such as the artificial horizon. In June 2022, the centenary of the first aerial crossing of the South Atlantic, it was announced that Faro Airport will officially change its name to Gago Coutinho Airport, in honour of Carlos Viegas Gago Coutinho. The journey First aircraft The journey started at the Bom Sucesso Naval Air Station in the Tagus, near the Belém Tower in Lisbon, at 1 ...
