Gilbertiodendron Dewevrei
''Gilbertiodendron dewevrei'' is a species of tree in the family Fabaceae, native to tropical rain forests in Central Africa. It is often the dominant tree species of the Guineo-Congolian rainforest. The timber is traded as ''limbali'', and is used for construction, flooring and railway sleepers. It is also used for making boats, furniture, tool handles and joinery and for making charcoal. Description ''Gilbertiodendron dewevrei'' is a large evergreen tree, reaching a height of up to . The crown is dense and allows little light through. The unbuttressed trunk is cylindrical, with a diameter of up to or more, the lower half usually being devoid of branches. The bark is rough, greyish-brown or yellowish brown, peeling off in large flakes. The leaves are pendulous and leathery, the underside being covered with papillae, and they often have a few glands near the margins. They are alternate and pinnate with two to five pairs of leaflets. Each leaflet is ovate or elliptical, the lowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivindo National Park
Ivindo National Park is a national park in east-central Gabon in Central Africa, straddling the border of the Ogooué-Ivindo and Ogooué-Lolo provinces. Its creation was announced in August 2002 by then-President Omar Bongo at the Earth Summit in Johannesburg, along with Gabon’s 12 other terrestrial national parks. Most famous for the spectacular Kongou and Mingouli waterfalls of the Ivindo River, known as the “wonders of Ivindo”, the park also includes the Ipassa Makokou Biosphere Reserve and Langoué Baï, one of the 5 most important forest clearings in Central Africa. The park was designated as a UNESCO UNESCO World Heritage Site in 2021 for its outstanding biodiversity and relatively intact tropical forest ecosystem. Physical Geography Physical features of the park include the Ivindo River, the park is the main tributary to the Ogooué, and Mount Kingué (749 m) and Mount Ngouadi (870 m). Average rainfall is 1672 mm, with peaks in rainfall between September ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Democratic Republic Of The Congo
The Democratic Republic of the Congo (french: République démocratique du Congo (RDC), colloquially "La RDC" ), informally Congo-Kinshasa, DR Congo, the DRC, the DROC, or the Congo, and formerly and also colloquially Zaire, is a country in Central Africa. It is bordered to the northwest by the Republic of the Congo, to the north by the Central African Republic, to the northeast by South Sudan, to the east by Uganda, Rwanda, and Burundi, and by Tanzania (across Lake Tanganyika), to the south and southeast by Zambia, to the southwest by Angola, and to the west by the South Atlantic Ocean and the Cabinda exclave of Angola.

Angraecum
The genus ''Angraecum'', abbreviated as Angcm in horticultural trade, common name comet orchid, contains about 220 species. Etymology Despite the genus's distribution being largely confined to Africa and its offshore islands, the genus name is a latinization of the Indonesian and Malay word anggrek (“orchid”), itself ultimately from Javanese ꦲꦔ꧀ꦒꦿꦺꦏ꧀ (anggrék, “orchid”). Description Angraecums are quite varied vegetatively and florally, and are adapted to dry tropical woodland habitat and have quite fleshy leaves as a consequence. Most are epiphytes, but a few are lithophytes. The long-lasting flowers are racemose and grow from the leaf axils. They are mostly white, but a few are yellow, green or ochre. They all have a long spur at the back of the labellum (lip). In the case of ''Angraecum sesquipedale'', a species from Madagascar, on observing the spur in the lip, Charles Darwin made the hypothesis that, since the nectar was at the bottom of the sp ...

Pulveroboletus Bembae
''Pulveroboletus bembae'' is a species of fungus in the family Boletaceae that was first described in 2009. It is known only from the rainforest of northern Gabon, a region known for its high level of species diversity. Like all boletes, ''P. bembae'' has fleshy fruit bodies that form spores in tubes perpendicular to the ground on the underside of the cap. These yellowish tubes form a surface of pores, each about 1–2 mm in diameter. The brownish caps may reach up to wide, and rest atop pale brown stems up to long. The stems have a woolly, whitish yellow ring of tissue that is short-lived, and may be absent in older specimens. The spores of ''P. bembae'' are spindle- or fuse-shaped, and have rough surfaces—a detail observable when viewed with scanning electron microscopy. The fungus grows in a mycorrhizal relationship with ''Gilbertiodendron dewevrei'', the dominant tree species of the Guineo-Congolian rainforest. Other similar ''Pulveroboletus'' species in t ...

Ectomycorrhiza
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branched hyphae form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorilla
Gorillas are herbivorous, predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus ''Gorilla'' is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees and bonobos. Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 metres, weights between 100 and 270 kg, and arm spans up to 2.6 metres, depending on species and sex. They tend to live in troops, with the leader being called a silverback. The Eastern gorilla is distinguished from the Western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. The oldest gorilla known is Fatou (b. 1957), who is still alive at the advanced age of 65 years. Gorillas' ...

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elephants ...

Duiker
A duiker is a small to medium-sized brown antelope native to sub-Saharan Africa, found in heavily wooded areas. The 22 extant species, including three sometimes considered to be subspecies of the other species, form the subfamily Cephalophinae or the tribe Cephalophini. Taxonomy and phylogeny The tribe Cephalophini (formerly the subfamily Cephalophinae) comprises three genera and 22 species, three of which are sometimes considered to be subspecies of the other species. The three genera include ''Cephalophus'' (15 species and three disputed taxa), ''Philantomba'' (three species), and ''Sylvicapra'' (one species). The subfamily was first described by British zoologist John Edward Gray in 1871 in ''Proceedings of the Zoological Society of London''. The scientific name "Cephalophinae" probably comes from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The three disputed species in ''Cephalophus'' are Brooke's dui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...
