Cora Paraminor
''Cora paraminor'' is a species of basidiolichen in the family Hygrophoraceae. Found in Costa Rica, it was formally described as a new species in 2016 by Manuela Dal Forno, José Luis Chaves, and Robert Lücking. The specific epithet ''paraminor'' refers to its close relationship with '' Cora minor''. ''Cora paraminor'' is known to occur only at the type locality at the Los Santos Forest Reserve in Cerro de la Muerte. Here it grows in mountainous forest as an 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 phoroph ..., on the twigs and branches of trees. Its phylogenetically distinct namesake, ''C. minor'', is also found in Costa Rica, but in Chirripó National Park. The authors suggest this may represent an example of allopatric speciation resulting from geographic iso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Taxa Named By Robert Lücking
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allopatric Speciation
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chirripó National Park
Chirripó National Park is a national park of Costa Rica, encompassing parts of three provinces: San José, Limón and Cartago. It was established in 1975. It is named for its most prominent feature, Cerro Chirripó, which at is the highest mountain in Costa Rica. Geography Chirripó is the 38th most prominent peak in the world. In terms of Holdridge life zones, the park can be categorized into five ecosystems: lowland tropical wet forest, premontane tropical wet forest, lower montane wet forest, montane wet forest and subalpine wet forest (páramo). Most of the park consists of both primary rain forests and primary cloud forests. Around it changes to wet desert. Summiting the peak begins with a hike along a uphill trail from the town of San Gerardo de Rivas to the park ranger's refuge in the Los Crestones sector; that is followed by a walk to the peak. Climate The climate is dominated by two seasons: a dry season lasting from December to April and a wet season from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Basidiolichen
Basidiolichens are lichenized members of the Basidiomycota, a much smaller group of lichens than the far more common ascolichens in the Ascomycota. In arctic, alpine, and temperate forests, the most common basidiolichens are in the agaric genus ''Lichenomphalia'' (including former members of '' Omphalina'' or '' Gerronema'') and the clavarioid genus '' Multiclavula''. Several lichenized genera occur in tropical regions, the most common being the foliose '' Dictyonema''. Previously basidiolichens had been classified in their own subclass, Basidiolichenes.

Cerro De La Muerte
Cerro de la Muerte is a mountain peak of a massif in Costa Rica, it is located within the Tapantí — Cerro de la Muerte Massif National Park, and is the highest point on the Pan-American Highway. Toponymy Its name means "Mountain of Death", "Hill of Death" or "Summit of Death," since in the past crossing the mountains from the Valle Central meant a three- or four-day journey, on foot or on horseback, and many ill-prepared travelers succumbed to the cold and rain. However, the peak is now easily accessible since the Route 2 runs close by. Description A drivable track from the highway (Kilometer 89) leads to a peak, with its cluster of telecommunications aerials. A short hike is also available from the highway to another peak marked with a barrel. A sign marks the high point of the highway ( Route 2) at , from where the vehicle track and hiking trail begin. At this altitude, overnight temperatures can dip below freezing, but the sun soon raises the temperatures in the morning, ...
