Acantholichen Sorediatus
''Acantholichen sorediatus'' 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, Harrie Sipman, and Robert Lücking. The type specimen was collected from the Las Cruces Biological Station ( San Vito, Puntarenas) at an altitude of ; this area is part of the Cordillera Central. Here, in the undergrowth of a disturbed primary forest, it was found growing on a tree trunk along with other lichens, including ''Hypotrachyna'', '' Normandina'', and '' Leptogium''. The specific epithet refers to the soredia Soredia are common reproduction, reproductive structures of lichens. Lichens asexual reproduction, reproduce asexually by employing simple fragmentation and production of soredia and isidia.

Harrie Sipman
Henricus (Harrie) Johannes Maria Sipman (born 1945) is a retired Dutch lichenologist who specialised in tropical and subtropical lichens and authored or co-authored over 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010. Between 1990 and 1997 he edited and distributed the exsiccata ''Lichenotheca Latinoamericana a museo botanico Berolinensi edita''. Early life and education Sipman was born on 2 January 1945 in Sittard in the southern part of the Netherlands. As a schoolboy, he developed an interest in paleontology, collecting Cretaceous marine fossils from quarries in the hills surrounding his hometown. He later moved to Utrecht to study biology at Utrecht University. His first research project at university focused on paleontology, specifically the taxonomy of Cretaceous oysters. Through meticulous analysis, he demonstrated that morphological variations previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Robert Lücking
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichens Of Central America

University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails.

Soredium
Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria or green algae. These can be either scattered diffusely across the surface of the lichen's thallus Thallus (: 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. A thallus usually names the entir ..., or produced in localized structures called soralia. Fungal hyphae make up the basic body structure of a lichen. The soredia are released through openings in the upper cortex of the lichen structure. After their release, the soredia disperse to establish the lichen in a new location.

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 ...

Leptogium
''Leptogium'' is a genus of lichen-forming fungi in the family Collemataceae. It has about 110 species. Species formerly classified under ''Leptogium'' have since been divided among the genera ''Leptogium'', '' Pseudoleptogium'', and '' Scytinium''. ''Leptogium'' lichens are predominantly found on tree bark or soil, often among mosses, and sometimes on rocks in moist environments. Taxonomy In 2013, a proposal supported by molecular phylogenetics data was made to conserve the genus ''Leptogium'' with a conserved type, aiming to maintain the current broader classification including both small- and larger foliose species within ''Leptogium'', while segregating the smaller squamulose species into '' Scytinium''. This conservation was recommended by a vote of 14-0-1 to prevent the necessity of reclassifying about 100 species into new genera such as '' Malotium''. The proposal was widely supported by the Nomenclature Committee for Fungi as it simplifies the taxonomy and maintains hist ...

Normandina
''Normandina'' is a genus of lichen-forming fungi in the family Verrucariaceae. It has five species of crustose and squamulose (scaly) lichens. * '' Normandina acroglypta'' – Europe * '' Normandina chlorococca'' – Northern Europe * '' Normandina dictyospora'' – Falkland Islands * '' Normandina pulchella'' * '' Normandina simodensis'' The type species of the genus, ''Normandina jungermanniae'', is now considered synonymous A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language.

''Lauderlindsaya'' is a genus that was proposed by David and Hawksworth in 1989 to contain the lichenicolous fungus ''Sphaerulina chlorococca'', which was thought to grow parasitically on ''Normandina pulchella''. Later research showed that ''Lauderlindsaya'' represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primary Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without Disturbance (ecology), disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and Canopy (biology), canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debr ...
