Parmotrema Aptrootii
''Parmotrema aptrootii'' is a species of corticolous lichen in the family Parmeliaceae. Found in South America, it was described as new to science in 1992. The holotype specimen was collected in the Cuyuni-Mazaruni region of Guyana, where it was found growing on a Mahogany tree on the bank of the Kamarang River. It has a pale yellowish to greenish-grey thallus measuring up to about . The specific epithet honours Dutch lichenologist André Aptroot. The lichen has also been recorded from Acre, Brazil, where it is commonly found on dead branches in dense shrubby campinas Campinas (, ''Plains'' or ''Meadows'') is a Brazilian municipality in São Paulo State, part of the country's Southeast Region.

Parmotrema
''Parmotrema'' is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands. Members of the genus are commonly called ruffle lichens or scatter-rag lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Description ''Parmotrema'' is characterized by its typically large, moderately to loosely-attached foliose thallus with broad lobes that are usually more than 5 mm wide. There is a broad, naked zone around the margin of the lower surface, an epicortex with pores and an upper cortex with a palisade-plectenchymatous arrangement of hyphae. Ascospores are thick-walled and ellipsoid. Taxonomy The genus was proposed as a genus by Italian lichenologist Abramo Bartolommeo Massalongo in 1860, with '' Parmotrema perforatum'' as the type species. The genus name, composed of the Greek ''parmos'' (cup) an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campina (biome)
Campina is a Neotropical ecoregion found in the Amazon biome. It refers to vegetation that grows on infertile sandy soil with poor drainage. The term may be used to include open forest, shrubland and meadow, or may be restricted to treeless meadows. Open forest The term ''campina'' is related to '' campinarana''. The meaning of both is "wild field", and some consider that they are the same. The terms ''campina'' and ''campinarana'' both describe white sand savannas that are very poor in nutrients. They may be flooded periodically or seasonally, in which case the roots suffer from lack of aeration. The vegetation is stunted. Amazon ''campinas'' are defined as open forest on sandy soil where sunlight can reach the ground. More than half the species of orchid in the Amazon lowlands are found in this type of forest. The ''campina'' areas of the Amazon have a flowering peak in the dry season. Treeless shrubland or meadow For others, ''campina'' is distinguished as being completely tree ...

Acre, Brazil
Acre () is a state located in the west of the North Region of Brazil and the Amazonia Legal. Located in the westernmost part of the country, at a two-hour time difference from Brasília, Acre is bordered clockwise by the Brazilian states of Amazonas and Rondônia to the north and east, the Bolivian department of Pando to the southeast, and the Peruvian regions of Madre de Dios, Ucayali and Loreto to the south and west. The state, which has 0.42% of the Brazilian population, generates 0.2% of the Brazilian GDP. Its capital and largest city is Rio Branco. Other important places include Cruzeiro do Sul, Sena Madureira, Tarauacá and Feijó. Intense extractive activity in the rubber industry, which reached its height in the early 20th century, attracted Brazilians from many regions to the state. From the mixture of sulista, southeastern Brazil, nordestino, and indigenous traditions arose a diverse cuisine. It combines sun-dried meat (carne-de-sol) with pirarucu, a typical ...

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parmeliaceae
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: '' Xanthoparmelia'' ( 822 species), ''Usnea'' (355 species), ''Parmotrema'' ( 255 species), and ''Hypotrachyna'' (262 species). Nearly all members of the family have a symbiotic association with a green alga (most often ''Trebouxia'' spp., but '' Asterochloris'' spp. are known to associate with some species).Miadlikowska, J.

Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamarang River
Kamarang River is a river in Venezuela and Guyana, and a part of the Essequibo River basin. Route The river originates in Venezuela where it is called Río Camarán or Río Camurán. Its source is located right next to the Troncal 10, in the middle of the Gran Sabana region. The nascent river first flows in parallel to the road in a southeasterly direction. It then passes the road a few meters after the Campamento Kamoiran. Here the river forms the Kamoiran rapids. Its course then turns more eastward for several kilometers through open Savannah. Shortly after entering the disputed Guayana Esequiba territory in Guyana the river drops roughly 160 meters at the impressive Kamarang falls creating a 40 meter wide water curtain. The Kamarang River then flows through a deep forested gorge first north-, then eastbound. This area is very remote and inhabited by the Arecuna people and rarely visited as it is difficult to access from both Guyana and Venezuela. The river then flows east th ...
