Sticta Parahumboldtii
''Sticta parahumboldtii'' is a species of foliose lichen in the family Peltigeraceae. It is found in the Colombian Andes. Taxonomy The lichen was species description, formally described as a new species by lichenologists Bibiana Moncada and Robert Lücking. The Type (biology), type specimen was collected near the La Laguna de Chisacá (Cundinamarca Department, Cundinamarca) at an altitude of . The botanical name, species epithet refers to its resemblance to and close association with ''Sticta humboldtii''. The name "parahumboldtii" is derived from the Greek language, Greek prefix "para," meaning "next to" or "near." In a time-calibrated chronogram of the phylogeny of the genus ''Sticta'', ''Sticta parahumboldtii'' was most closely related to ''Sticta hirsutofuliginosa, S. hirsutofuliginosa'' and a clade containing ''Sticta atlantica, S. atlantica'', ''Sticita humboldtii, S. humboldtii'', and ''Sticta arachnosylvatica, S. arachnosylvatica''.

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 Arachnosylvatica
''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 ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fr ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plasti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metzgeria
''Metzgeria'' is a genus of thalloid liverworts in the family Metzgeriaceae.

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] |
Cordillera Oriental (Colombia)
The Cordillera Oriental ( en, Eastern Ranges) is the widest of the three branches of the Colombian Andes. The range extends from south to north dividing from the Colombian Massif in Huila Department to Norte de Santander Department where it splits into the Serranía del Perijá and the Cordillera de Mérida in Venezuelan Andes. The highest peak is Ritacuba Blanco at in the Sierra Nevada del Cocuy. Geography The western part of the Cordillera Oriental belongs to the Magdalena River basin, while the eastern part includes the river basins of the Amazon River, Orinoco River, and Catatumbo River. Within it, the Altiplano Cundiboyacense and the Sierra Nevada del Cocuy (with the only snowy peaks in this mountain range) stand out. The mountain range contains the most páramos in the world.
