Drift Seed
__NOTOC__ Drift seeds (also sea beans) and drift fruits are seeds and fruits adapted for long-distance dispersal by water. Most are produced by tropical trees, and they can be found on distant beaches after drifting thousands of miles through ocean currents. This method of propagation has helped many species of plant such as the coconut colonize and establish themselves on previously barren islands. Consequently, drift seeds and fruits are of interest to scientists who study these currents. In botanical terminology, a drift fruit is a kind of diaspore, and drift seeds and fruits are disseminules.

Seed Dispersal
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. However, this simplified view may ign ...

Ormosia
''Ormosia'' is a genus of legumes (family Fabaceae). The more than 100 living species, mostly trees or large shrubs, are distributed throughout the tropical regions of the world, some extending into temperate zones, especially in East Asia. A few species are threatened by habitat destruction, while the Hainan ormosia (''Ormosia howii'') is probably extinct already. Plants in this genus are commonly known as horse-eye beans or simply ormosias, and in Spanish by the somewhat ambiguous term ''"chocho"''. The scientific name ''Ormosia'' is a ''nomen conservandum'', overruling ''Toulichiba'' which is formally rejected under the ''International Code of Nomenclature for algae, fungi, and plants''. The seeds of these plants are poisonous if eaten, but often look pretty, with bright colors and decorative patterns reminiscent of an eye; the common name "horse-eye beans" refers to these seeds. They resemble the seeds of ''Abrus'', snoutbeans (''Rhynchosia''), and ''Adenanthera'', but are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency ...

Manicaria
''Manicaria'' is a palm genus which is found in Trinidad, Central and South America. It contains two recognized species: #'' Manicaria martiana'' Burret – Colombia, northwestern Brazil #''Manicaria saccifera'' Gaertn. – Central America, Trinidad, Venezuela, Colombia, Ecuador, Peru, northwestern Brazil It has one of the largest known leaves in the plant kingdom (up to 8 metres in length). ''Manicaria'' thrives in swamps or estuarine areas where river meets ocean. In the Tortuguero region of Costa Rica, where ''Manicaria saccifera'' is plentiful, local people know this palm as "Palma Real", or "Royal Palm". Its heavy, large leaves are valued over other palm species as the best material for roof thatching. ''Manicaria saccifera'' is an obligate swamp species, and as most other palms, it thrives in the wet, humid conditions of tropical lowland forests. Myers (1981) states "In the humid environments of the neo-tropics there is an increase in the abundance of understory palms ...

Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lodoicea
''Lodoicea'', commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, ''Lodoicea maldivica'', is endemic to the islands of Praslin and Curieuse in the Seychelles. It has the biggest seed in a plant. It formerly also was found on the small islets of St Pierre, Chauve-Souris, and Ile Ronde (Round Island), all located near Praslin, but had become extinct there for a time until recently reintroduced. Taxonomy The name of the genus ''Lodoicea'' is given by Philibert Commerson, it may be derived from ''Lodoicus'', a Latinised form of ''Louis'' (typically '' Ludovicus''), in honour of King Louis XV of France. Other sources say that ''Lodoicea'' is from Laodice, the daughter of Priam and Hecuba. ''Lodoicea'' belongs to the Coryphoideae subfamily and tribe Borasseae. Borasseae is represented by four genera in Madagascar and one in Seychelles out of the seven worldwide. They are distributed on the coastlands surro ...

Tropics
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polynesia
Polynesia () "many" and νῆσος () "island"), to, Polinisia; mi, Porinihia; haw, Polenekia; fj, Polinisia; sm, Polenisia; rar, Porinetia; ty, Pōrīnetia; tvl, Polenisia; tkl, Polenihia (, ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including language relatedness, cultural practices, and traditional beliefs. In centuries past, they had a strong shared tradition of sailing and using stars to navigate at night. The largest country in Polynesia is New Zealand. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Geographical Society of Paris. By tradition, the islands located in the southern Pacific have ...
