Sticta Pseudohumboldtii
''Sticta pseudohumboldtii'' is a species of foliose lichen in the family Peltigeraceae. It is found in the Colombian Andes. Taxonomy The lichen was formally described as a new species in by lichenologists Bibiana Moncada and Robert Lücking.The type specimen was collected in the Parque Ecológico Matarredonda (El Verjón, Cundinamarca) at an altitude of . The species epithet refers to its resemblance to ''Sticta humboldtii'', but with the added Greek prefix "pseudo," meaning "false." This is because, unlike the similarly named ''S. parahumboldtii'', ''S. pseudohumboldtii'' is not the closest relative to ''S. humboldtii''. Rather, it is a sister species to the morphologically distinct '' S. arachnofuliginosa''. In a time-calibrated chronogram of the phylogeny of the genus ''Sticta'', ''Sticta pseudohumboldtii'' was most closely related to '' S. arachnofuliginosa''; these two species comprise a clade with a sister relationship to '' S. atlantica'' ...

Robert Lücking
Robert Lücking (born 1964) is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves. Life and career Born in Ulm in 1964, Lücking earned both his master's (1990) and PhD degree (1994) at the University of Ulm. Both degrees concerned the taxonomy, ecology, and biodiversity of foliicolous lichens. His graduate supervisor was mycologist and bryologist Sieghard Winkler, who had previously studied epiphyllous (upper leaf-dwelling) fungi in El Salvador and Colombia. In 1996 Lücking was awarded the Mason E. Hale award for an "outstanding doctoral thesis presented by a candidate on a lichenological theme". His thesis was titled ''Foliikole Flechten und ihre Mikrohabitatpraferenzen in einem tropischen Regenwald in Costa Rica'' ("Foliicolous lichens and their microhabitat preferences in a tropical rainforest in Costa Rica"). In this work, Lücking recorded 177 foliicolous lichen species from the shrub layer in a Costa Rican tropical forest. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sticta
''Sticta'' is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. ''Sticta'' species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens. Description The vegetative bodies of the ''Sticta'', the thalli, are foliose, or leafy in appearance. They typically have dimensions of in diameter, although specimens with diameters of up to have been recorded. The lobes are rounded, and the upper surface is black or brown, while the lower surface has a light to dark brown layer of fine hairs (a ), with a few craters, called . Thalli often smell of shrimp or fish. The vegetative reproductive structures called isidia or soredia are often present on ...

They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Oropogon Bicolor
''Oropogon'' is a genus of lichenised ascomycetes in the large family Parmeliaceae. It is a genus of roughly 40 currently accepted species. It was previously included in the family Alectoriaceae, but this group has since been subsumed into the Parmeliaceae. All members of the genus have a fruticose growth form. The most obvious synapomorphic character which separates ''Oropogon'' from the rest of the family is the large brown, muriform ascospores (i.e. with transverse and longitudinal walls) that occur singly in each ascus.

Metzgeria
''Metzgeria'' is a genus of thalloid liverworts in the family Metzgeriaceae. Taxonomy The genus was named in honor of Johann Metzger (1771–1844), a German copper engraver and art restorer from Staufen im Breisgau, in Baden-Württemberg, a friend of Giuseppe Raddi and pupil of the great Florentine engraver Raffaello Sanzio Morghen (1753–1833).K.

Cordillera
A cordillera is an extensive chain and/or network system of mountain ranges, such as those in the west coast of the Americas. The term is borrowed from Spanish, where the word comes from , a diminutive of ('rope'). The term is most commonly used in physical geography p. 687 (Encyclopedia Americana Corp., 1918): "It is used particularly in physical geography, although in geology also it is sometimes applied...." and is particularly applied to the various large |
Epiphyte
An epiphyte is an organism that grows on the surface of a 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. 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 tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Páramo
Páramo () can refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be " evolutionary hot spots", that meaning that it's among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ecuado ...
