Parmelia Encryptata
''Parmelia encryptata'' is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. Found in the Iberian Peninsula, it was formally described as a new species in 2011 by Ana Crespo, Pradeep Kumar Divakar, and Maria del Carmen Molina. It is cryptic species that is a member of the '' Parmelia sulcata'' species complex, and it is morphologically indistinguishable from that lichen. Molecular phylogenetic analysis, however, shows that it is a genetically unique species originating from a different lineage Lineage may refer to: Science * Lineage (anthropology), a group that can demonstrate its common descent from an apical ancestor or a direct line of descent from an ancestor * Lineage (evolution), a temporal sequence of individuals, populati .... ''Parmelia encryptata'' has been estimated to have diverged from the '' P. squarrosa'' complex about 5.4 million years ago. References encryptata Lichen species Lichens described in 2011 ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Parmelia Squarrosa
''Parmelia squarrosa'', commonly known as the bottlebrush shield lichen, is a species of foliose lichen in the family Parmeliaceae. It occurs in east Asia, Europe, and eastern North America, where it typically grows on tree bark, much less frequently on rocks, and rarely on moss. Because of its abundance, widespread distribution, and stable populations, it has been assessed as a species of least concern by the International Union for Conservation of Nature. ''Parmelia saxatilis'' is quite similar in appearance ''Parmelia squarrosa'' and the latter was quite often confused with the former, especially in herbarium collections. Molecular phylogenetic analysis proved the genetic distinctness between the two species, which are morphologically distinguished by difference in rhizine structure. Taxonomy The lichen was described as a new species in 1971 by American mycologist Mason Hale. The type specimen was collected by Hale in Shenandoah National Park, Virginia, USA, at ...

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 Friedrich Burdach ...

Foliose Lichen
Foliose lichen is one of the morphological classes of lichens, which are complex organisms that arise from the symbiotic relationship between fungi and a photosynthetic partner, typically algae. This partnership allows lichen to live in diverse climates that can range from cold, dry mountains to wet, warm valleys. Lichens develop quite slowly with recorded growth rates of 0.01–27mm/year depending on the species. Their lifespan averages between 30 and 60 years. Lichens have a main body part called the thallus, which is composed of hyphae, and houses the cortex and medulla. The cortex contains the photosynthetic cells while the medulla allows for gas exchange and makes up the bulk of the lichen's thallus. There are three main types of lichens: crustose, foliose, and fruticose. Foliose lichen are characterised by flattened leafy thalli, and an upper and lower cortex. Many have numerous layers, which are stratified, and aid in identifying different types. Foliose lichens attach to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parmelia Sulcata
''Parmelia sulcata'' is a foliose lichen in the family Parmeliaceae. It is very tolerant of pollution and has a cosmopolitan distribution, making it one of the most common lichens. It harbours a unicellular ''Trebouxia'' green algal symbiont. Taxonomy First described by Thomas Taylor in 1836 under its current name, ''Parmelia sulcata'' has a large number of named varieties and forms, but no subspecies despite its extensive range. Most taxonomists have left the species in the genus to which Taylor originally assigned it, though mycologist Maurice Choisy assigned it to the genus ''Parmotrema'' in 1952. The genus name ''Parmelia'' is a compound of two Greek words: ''parme'', meaning "fruit bowl" and ''-eileo'', meaning "enclosed". This likely refers to the lecanorine apothecia of species belonging to the genus. The specific epithet ''sulcata'' is derived from ''sulcatus'', meaning "grooved" or "furrowed". The species is known by a number of colloquial names, including hammered sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
