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 ferns.

Polypodiaceae
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial. Description Stems of Polypodiaceae range from erect to long-creeping. The fronds are entire, pinnatifid, or variously forked or pinnate. The petioles lack stipules. The scaly rhizomes are generally creeping in nature. Polypodiaceae species are found in wet climates, most commonly in rain forests. In temperate zones, most species tend to be epiphytic or epipetric. Notable examples of ferns in this family include the resurrection fern (''Pleopeltis polypodioides'') and the golden serpent fern (''Phlebodium aureum''). Taxonomy Two distinct circumscriptions of the family are in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern America (WGSRPD)
The World Geographical Scheme for Recording Plant Distributions (WGSRPD) is a biogeographical system developed by the international Biodiversity Information Standards (TDWG) organization, formerly the International Working Group on Taxonomic Databases. The WGSRPD standards, like other standards for data fields in botanical databases, were developed to promote "the wider and more effective dissemination of information about the world's heritage of biological organisms for the benefit of the world at large". The system provides clear definitions and codes for recording plant distributions at four scales or levels, from "botanical continents" down to parts of large countries. Current users of the system include the International Union for Conservation of Nature (IUCN), the Germplasm Resources Information Network (GRIN), and the World Checklist of Selected Plant Families (WCSP). Principles of organization The scheme is one of a number developed by Biodiversity Information Standard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 le ...

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Flora Of Colombia
The Flora of Colombia is characterized by over 28,000 species of green plants. National Flower of Colombia The national flower of Colombia is the orchid ''Cattleya trianae'' which was named after the Colombian naturalist José Jerónimo Triana. The orchid was selected by botanist Emilio Robledo, in representation of the Colombian Academy of History to determine the most representative flowering plant of Colombia. He described it as one of the most beautiful flowers in the world and selected ''Cattleya trianae'' as National symbol. National Tree of Colombia The national tree of Colombia is the palm ''Ceroxylon quindiuense'' (Quindío wax palm) which was named after the Colombian Department of Quindío where is located the Cocora valley, the only habitat of this restricted range species. The Quindío wax palm was selected as the national tree by the government of Belisario Betancur and was the first tree officially declared as a protected species in Colombia. ''C.quindiuens ...

Flora Of Ecuador
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Haiti
The wildlife of Haiti is important to the country because of its biodiversity. According to the World Conservation Monitoring Centre, Haiti is considered to be "one of the most biologically significant countries of the West Indies". With an estimated 5,600 plant species on the island of Hispaniola, some of which only occur in Haiti, 36% are considered as endemic to the island. A mountainous area country, it is situated in the western three-eighths of Hispaniola and shares a border with the Dominican Republic. There are nine life zones, from low desert to high cloud forests, as well as four mountain ranges, and hundreds of rivers and streams and the coral reefs in the seas that surround the islands. Issues of environmental damage, expanding population, deforesting and erosion are of concern; less than 2% of the original forest remains on account of deforestation. This degradation is traced from the 17th century to 19th century starting with the French colonization of the Haiti and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Venezuela
The flora of Venezuela consists of a huge variety of unique plants; around 38% of the estimated 30,000 species of plants found in the country are endemic to Venezuela. Overall, around 48% of Venezuela's land is forested; this includes over 60% of the Venezuelan Amazon. These rainforests are increasingly endangered by mining and logging activities. Venezuela's habitats range from the Andes mountains in the west to the Amazon Basin rainforest in the south, via extensive Llanos plains and Caribbean coast in the center and the Orinoco River Delta in the east. They include xeric scrublands in the extreme northwest and coastal mangrove forests in the northeast. Its cloud forests and lowland rainforests are particularly rich, for example hosting over 25,000 species of orchids.Dydynski, K; Beech, C (2004). Venezuela'. Lonely Planet. . Retrieved 10 March 2007. p42 These include the ''flor de mayo'' orchid (''Cattleya mossiae''), the national flower. Venezuela's national tree is the '' arag ...
