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 ...

Gabon
Gabon (; ; snq, Ngabu), officially the Gabonese Republic (french: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly and its population is estimated at million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita (PPP) i ...

Minkébé National Park
Minkébé National Park is a national park in the extreme northeast of Gabon. It covers an area of 7,570 km2. The WWF recognized it as an area needing protection as early as 1989 and has been actively working towards protecting the forest since 1997. The park was established as a provisional reserve in 2000 but the Minkébé National Park itself was officially recognized and established by the Gabonese government in August 2002. It is recognized as a critical site for conservation by the IUCN and has been proposed as a World Heritage Site. History and management The Fang people once inhabited the Minkébé area but on becoming a protected area the park now has no permanent human population. The name Minkébé derives from the Fang word ''minkegbe'', which means 'valleys' or 'ditches'. Historically, the park was under former French army control in the 1920s. In 1997, the WWF initiated a management program and established two main centres of forest command, one at Oyem, the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trama (mycology)
In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue that is commonly referred to as the "flesh" of mushrooms and similar fungi.Largent D, Johnson D, Watling R. 1977. ''How to Identify Mushrooms to Genus III: Microscopic Features''. Arcata, CA: Mad River Press. . pp. 60–70. The second use is more specific, and refers to the "hymenophoral trama" that supports the hymenium. It is similarly interior, connective tissue, but it is more specifically the central layer of hyphae running from the underside of the mushroom cap to the lamella or gill, upon which the hymenium rests. Various types have been classified by their structure, including trametoid, cantharelloid, boletoid, and agaricoid, with agaricoid the ...

Universal Veil
In mycology, a universal veil is a temporary membranous tissue that fully envelops immature fruiting bodies of certain gilled mushrooms. The developing Caesar's mushroom (''Amanita caesarea''), for example, which may resemble a small white sphere at this point, is protected by this structure. The veil will eventually rupture and disintegrate by the force of the expanding and maturing mushroom, but will usually leave evidence of its former shape with remnants. These remnants include the volva, or cup-like structure at the base of the stipe, and patches or "warts" on top of the cap. This macrofeature is useful in wild mushroom identification because it is an easily observed, taxonomically significant feature. It is a character present among species of basidiomycete fungi belonging to the genera ''Amanita'' and ''Volvariella''. This has particular importance due to the disproportionately high number of potentially lethal species contained within the former genus. A membrane envel ...

Pileipellis
The pileipellis is the uppermost layer of hyphae in the pileus of a fungal fruit body In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particu .... It covers the trama, the fleshy tissue of the fruit body. The pileipellis is more or less synonymous with the cuticle, but the cuticle generally describes this layer as a macroscopic feature, while pileipellis refers to this structure as a microscopic layer. Pileipellis type is an important character in the identification of fungi. Pileipellis types include the cutis, trichoderm, epithelium, and hymeniderm types. Types Cutis A cutis is a type of pileipellis characterized by hyphae that are repent, that is, that run parallel to the pileus surface. In an ixocutis, the hyphae are gelatinous. Trichoderm In a trichoderm, the outermost hyphae emer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp (fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium (hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various ''Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as ''umbonate''. An umbo is a knobby protrusion at the center of th ...

Baka (Cameroon And Gabon)
The Baka people, known in the Congo as Bayaka (''Bebayaka, Bebayaga, Bibaya''), are an ethnic group inhabiting the southeastern rain forests of Cameroon, northern Republic of the Congo, northern Gabon, and southwestern Central African Republic. They are sometimes called a subgroup of the Twa, but the two peoples are not closely related. Likewise, the name "Baka" is sometimes mistakenly applied to other peoples of the area who, like the Baka and Twa, have been historically called pygmies, a term that is now considered derogatory. Identity Baka people are all hunter-gatherers, formerly referred to as pygmies, located in the Central African rain forest. Having average heights of 1.52 meters (5 feet) on average as well as living semi-nomadic lifestyles, the Baka are often discriminated against and marginalized from society. They reside in southeastern Cameroon, northern Gabon and in the northern part of the Republic of Congo. In Congo, the Baka people are otherwise known as the ...

Specific Name (botany)
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (biology)
In biology a section ( la, sectio) is a taxonomic rank that is applied differently in botany and zoology. In botany Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species: * Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species In zoology Within fauna (animals), 'section' refers to a ''zoological'' rank below the order, but above the family: * Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species In bacteriology The International Code of Nomenclature for Bacteria The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P.

Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Korotayev A.br>Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries.
