Cryptophaea (lichen)
''Cryptophaea'' is a genus of lichen-forming fungi in the family Arthoniaceae. Initially described as a monotypic genus in 2016 with the type species, '' C. phaeospora'', from the Congo Basin, it was expanded in 2024 to include four species of crustose lichens found in Brazil. ''Cryptophaea'' species are characterised by their firmly attached thalli, which are typically whitish grey-green and hydrophobic. The genus has diverse morphological features, including and soredia in some species. ''Cryptophaea'' lichens are corticolous, growing on tree bark in various tropical forest ecosystems, from near sea level to elevations over 1000 metres. Recent molecular phylogenetic studies have revealed complex relationships between ''Cryptophaea'' and other genera within Arthoniaceae, suggesting potential taxonomic revisions may be necessary as more data becomes available. Taxonomy The fungal genus ''Cryptophaea'' was circumscribed by Dries Van den Broeck and Damien Ertz in 2016. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical Forest
Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the Tropic of Cancer, tropics of Cancer and Tropic of Capricorn, Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate climate, temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of ...

Cryptothecia
''Cryptothecia'' is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves, in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid (whispy, like teased wool). The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek ''krypto'' = "to conceal" and ''theke'' = "a container or sheath". It contains '' Trentepohlia'', a green alga, as its photobiont partner. Two species have been described in North America.Brodo, I. M., S. D. Sharnoff, and S. Sharnoff. 2001. Lichens of North America.

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Phylogenetic
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Name
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 cultivar group, 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, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, 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 variou ...

Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant biological specimen, specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called ''exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxon, taxa. Some specimens may be Type (botany), types, some may be specimens distributed in published series called exsiccata, exsiccatae. The term herbarium is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey, Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of ...

Orientale Province
Orientale Province () is one of the former provinces of the Democratic Republic of the Congo and its predecessors the Congo Free State and the Belgian Congo. It went through a series of boundary changes between 1898 and 2015, when it was divided into smaller units. The District of Orientale Province was created from Stanley Falls District on 15 July 1898. The district was expanded to become Orientale Province in 1913. It was divided in 1933 into Costermansville Province, Costermansville (later Kivu) and Stanleyville Province. Stanleyville Province was renamed Orientale Province from 1947 to 1963, when it was broken up into Kibali-Ituri, Uélé and Haut-Congo provinces. Orientale Province was reconstituted in 1966. Between 1971 and 1997 it was called Haut-Zaïre, then it returned to the name of Orientale. The province contained the Bas-Uele District, Bas-Uele, Haut-Uele District, Haut-Uele, Ituri District, Ituri and Tshopo District, Tshopo districts. These were elevated to province ...

Tshopo District
Tshopo is one of the 21 provinces of the Democratic Republic of the Congo created in the 2015 repartitioning. It is situated in the north central part of the country on the Tshopo River, for which it is named. Tshopo, Bas-Uele, Haut-Uele, and Ituri provinces are the result of the dismemberment of the former Orientale province. Tshopo was formed from the Tshopo district and the independently administered city of Kisangani which retained its status as a provincial capital. The 2020 population was estimated to be 2,829,700. History From 1963 to 1966, the area was constituted as the province of Haut-Congo (Upper Congo). It was merged into Orientale Province in 1966 as, separately, the District of Tshopo and the city of Kisangani. The Presidents (later governors) of Haut-Congo were: * 1963 – 26 June 1963: Georges Grenfell (b. 1908) * 26 June 1963 – 1964: Paul Isombuma * 1964 – August 1964: François Aradjabu * August 1964 – 5 Nov 1966: Jean Marie Al ...

Yangambi
Yangambi is a town in Isangi territory of Tshopo province, Democratic Republic of the Congo. Location Yangambi is on the north side of the Congo River and lies on the R408 road which connects it to Kisangani 100 kilometers to the east. This road is unpaved, rarely used in the rainy season and difficult to use at all times of the year. The roads linking Yangambi to Weko and Isangi are also very poor. The river provides an alternative transport route. The town was once served by the small Yangambi Airport. Weather Mean annual rainfall is . August is the wettest month and February the driest. The skies tend to be partly cloudy even during the drier seasons. Yangambi Biosphere Reserve 235,000 hectares of forest around Yangambi were declared a Biosphere Reserve in 1976, part of UNESCO’s Man and the Biosphere Programme (MAB). The Yangambi Biosphere Reserve comprises secondary forests with '' Pycnanthus angolensis'' and '' Fagara macrophylla'', semi deciduous secondary rain fore ...
