Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quebradillas, Puerto Rico
Quebradillas (, ) is a town and municipality of the island of Puerto Rico located in the north-western shore bordering the Atlantic Ocean, north of San Sebastián; east of Isabela; and west of Camuy. Quebradillas is spread over seven barrios and Quebradillas Pueblo (the downtown area and the administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area. Quebradillas is called "''La Guarida del Pirata''" (The Pirate's Hideout). A well-known beach in the area, Puerto Hermina, is home to an old structure known to have been a hiding place for pirates and their contraband. History The town was founded in 1823 by Felipe Ruiz. There were many factors that cause the inhabitants of this territory of Puerto Rico to be independent from the towns that formed the Hato de la Tuna resulting in the formation of a new municipality. The town lacked chapels or churches, religious services nor priests, a place to bury the dead, a post office, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hatillo, Puerto Rico
Hatillo () is a town and municipality located in Puerto Rico's north coast, bordered by the Atlantic Ocean to the north, Lares and Utuado to the south, Camuy to the west, and Arecibo to the east. According to the 2000 US Census Hatillo is spread over nine barrios and Hatillo Pueblo (the downtown area and the administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area. History Agustín Ruiz Miranda, a Canarian immigrant, founded Hatillo on approximately ten (a cuerda is 0.97 acre, also called a Spanish acre) in 1823. Miranda granted this land on the condition that public buildings be erected and wide streets be built, and that the remaining land be sold or used for homes. In its first year, Hatillo had 910 people; increasing to 2,663 inhabitants the following year distributed among the central town and the barrios of Carrizales, Capáez, Naranjito, Corcovado, Buena Vista (formerly Yeguada Occidental), Campo Alegre (fo ...

Sorus
A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. A coenosorus (plural coenosori) is a compound sorus composed of multiple, fused sori. Etymology This New Latin word is from Ancient Greek σωρός (''sōrós'' 'stack, pile, heap'). Structure In lichens and other fungi, the sorus is surrounded by an external layer. In some red algae, it may take the form of depression into the thallus. In ferns, the sori form a yellowish or brownish mass on the edge or underside of a fertile frond. In some species, they are protected during development by a scale or film of tissue called the indusium, which forms an umbrella-like cover. Lifecycle significance Sori occur on the sporophyte generation, the sporangia within producing haploid meiospores. As the sporangia mature, the indusium shrivels so that spore release is unimpeded. The sporangia then burst and release the spores. As an aid to identification The shape, arrangem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thelypteridaceae
Thelypteridaceae is a family of about 900 species of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the suborder Aspleniineae. Alternatively, the family may be submerged in a very broadly defined family Aspleniaceae as the subfamily Thelypteridoideae. The ferns are terrestrial, with the exception of a few which are lithophytes (grow on rocks). The bulk of the species are tropical, although there are a number of temperate species. These ferns typically have creeping rhizomes. The fronds are simply pinnate to pinnate- pinnatifid. There is either no frond dimorphism or only mild dimorphism, either open venation or very simple anastomosing. The sori are mostly reniform in shape and have indusia, except for the ''Phegopteris'' group. Classification During the early and mid 1900's all thelypterioid ferns were included in the genus '' Dryopteris'' because of the sorus shape. However, there are a great many d ...
