Trinidad Mangroves
The Trinidad mangroves ecoregion (WWF ID: NT1436) covers the separate mangrove forest areas on the coast of the island of Trinidad, in the country of Trinidad and Tobago. The character of the mangroves is affected by the large amount of fresh water flowing out of the Orinoco River and Amazon River to the south, which flow northwest around the island. The mangroves of Trinidad are found on all coasts, and are usually in the estuaries of rivers, but also found in coastal lagoons. Location and description The largest mangrove wetland on Trinidad is the Nariva Swamp, a permanent brackish lagoon, on the east coast. It is separated from the sea by a sand bar, and has a salinity of 18-25 ‰. The water level typically fluctuates by 0.6 - 1.9 meters. The second largest is the Caroni Swamp, formed where the Caroni River enters Gulf of Paria just south of Port of Spain in the northwest of the island. The ecoregion surrounding the mangroves on the inland side is Trinidad and Toba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caroni Swamp
The Caroni Swamp is the second largest mangrove wetland in Trinidad and Tobago. It is located on the west coast of Trinidad, south of Port of Spain and northwest of Chaguanas, where the Caroni River meets the Gulf of Paria. The Caroni Swamp is an estuarine system comprising 5,611 hectares of mangrove forest and herbaceous marsh, interrupted by numerous channels, and brackish and saline lagoons, and with extensive intertidal mudflats on the seaward side. This swamp is an important wetland since it is ecologically diverse, consisting of marshes, mangrove swamp and tidal mudflats in close proximity. The wetland provides a variety of habitats for flora and faunal species and as such, supports a rich biodiversity. It is highly productive system that provides food and protection and is a nursery for marine and freshwater species. Description The Caroni Swamp is a 12,000 acre swamp located on the west coast of the island of Trinidad. It is one of the largest mangrove forest on the ...

Tropical Rainforest Climate
A tropical rainforest climate, humid tropical climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as the coast of southeast Florida, USA, and Okinawa, Japan that fall into the tropical rainforest climate category. They experience high mean annual temperatures, small temperature ranges, and rain that falls throughout the year. Regions with this climate are typically designated ''Af'' by the Köppen climate classification. A tropical rainforest climate is typically hot, very humid, and wet. Description Tropical rain forests have a type of tropical climate in which there is no dry season—all months have an average precipitation value of at least . There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be very similar to the next, while the change in temperature between day and night ...

Neotropical Ecoregions
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bon Accord Lagoon
''Bon'', also spelled Bön () and also known as Yungdrung Bon (, "eternal Bon"), is a Tibetan religious tradition with many similarities to Tibetan Buddhism and also many unique features.Samuel 2012, pp. 220-221. Bon initially developed in the tenth and eleventh centuries, but may retain elements from earlier religious traditions (which also used the term Bon).Kvaerne 1996, pp. 9-10. Bon remains a significant minority religion in Tibet (especially in Eastern Tibet) and in the surrounding Himalayan regions. The relationship between Bon and Tibetan Buddhism has been a subject of debate. According to the modern scholar Geoffrey Samuel, while Bon is "essentially a variant of Tibetan Buddhism" with many resemblances to Nyingma, it also preserves some genuinely ancient pre-Buddhist elements. David Snellgrove likewise sees Bon as a form of Buddhism, albeit a heterodox kind. Similarly, John Powers writes that "historical evidence indicates that Bön only developed as a self-consci ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Mangrove Swamp
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. Mangrove forests grow mainly at tropical and subtropical latitudes because mangroves cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate.What is a mangrove forest? National Ocean Service, NOAA. Updated: 25 March 2021. Retrieved: 4 October 2021. Many mangrove forests can be recognised by their dense tangle of prop roots that make the trees appear to be standing on stilts above the water. This tangle of roots allows the trees to handle the daily rise and fall of tides, which means that most mangroves get flooded at least twice per day. ...

Conocarpus Erectus
''Conocarpus erectus'', commonly called buttonwood or button mangrove, is a mangrove shrub in the family Combretaceae. This species grows on shorelines in tropical and subtropical regions around the world. Range Locations it is known from include Florida, Bermuda, the Bahamas, the Caribbean, Central and South America from Mexico to Brazil on the Atlantic Coast and Mexico to Ecuador on the Pacific Coast, western Africa and in Melanesia and Polynesia. It was introduced in Kuwait because it can thrive in high temperatures and absorbs brackish water. Description ''Conocarpus erectus'' is usually a dense multiple-trunked shrub, tall, but can grow into a tree up to or more tall, with a trunk up to in diameter. The United States National Champion green buttonwood is tall, has a spread of , and a circumference of . The bark is thick and has broad plates of thin scales which are gray to brown. The twigs are brittle, and angled or narrowly winged in cross-section. The leaves are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laguncularia Racemosa
''Laguncularia racemosa'', the white mangrove, is a species of flowering plant in the leadwood tree family, Combretaceae. It is native to the coasts of western Africa from Senegal to Cameroon, the Atlantic Coast of the Americas from Bermuda and Florida to the Bahamas, Mexico, the Caribbean, and south to Brazil; and on the Pacific Coast of the Americas from Mexico to northwestern Peru, including the Galápagos Islands. It is a mangrove tree, growing to tall. The bark is gray-brown or reddish, and rough and fissured. Pneumatophores and/or prop roots may be present, depending on environmental conditions. The leaves are opposite, elliptical, long, and broad, rounded at both ends, entire, smooth, leathery in texture, slightly fleshy, without visible veins, and yellow-green in color. The petiole is stout, reddish, and long, with two small glands near the blade that exude sugars. The white, bell-shaped flowers are mostly bisexual and about long. The fruit is a reddish-brown dr ...

Avicennia Schaueriana
''Avicennia'' is a genus of flowering plants currently placed in the bear's breeches family, Acanthaceae. It contains mangrove trees, which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots. They are also commonly known as ''api api'', which in the Malay language means "fires", a reference to the fact that fireflies often congregate on these trees. Species of ''Avicennia'' occur worldwide south of the Tropic of Cancer. The taxonomic placement of ''Avicennia'' is contentious. In some classifications, it has been placed in the family Verbenaceae, but more recently has been placed by some botanists in the monogeneric family Avicenniaceae. Recent phylogenetic studies have suggested that ''Avicennia'' is derived from within Acanthaceae, and the genus is included in that family in the Angiosperm Phylogeny Group system. Designation of species is made difficult by the great variations in form of ''Avicennia marina''. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avicennia Germinans
''Avicennia germinans'', the black mangrove, is a shrub or small tree growing up to 12 meters (39 feet) in the acanthus family, Acanthaceae. It grows in tropical and subtropical regions of the Americas, on both the Atlantic and Pacific Coasts, and on the Atlantic Coast of tropical Africa, where it thrives on the sandy and muddy shores where seawater reaches. It is common throughout coastal areas of Texas and Florida, and ranges as far north as southern Louisiana and coastal Georgia in the United States. Like many other mangrove species, it reproduces by vivipary. Seeds are encased in a fruit, which reveals the germinated seedling when it falls into the water. Unlike other mangrove species, it does not grow on prop roots, but possesses pneumatophores that allow its roots to breathe even when submerged. It is a hardy species and expels absorbed salt mainly from its leathery leaves. The name "black mangrove" refers to the color of the trunk and heartwood. The leaves often appear ...

Rhizophora Racemosa
''Rhizophora racemosa'' is a species of mangrove tree in the family Rhizophoraceae. It has a patchy distribution on the Pacific coast of Central and South America, occurs in places on the Atlantic coast of that continent, and has a more widespread range on the Atlantic coast of West Africa. Description Members of the genus ''Rhizophora'' are very similar to each other in morphology. They grow up to tall often with aerial stilt roots, but in more marginal habitats are shorter, more branched and scrubby. The leaves grow in opposite pairs, each pair with two interlocking stipules. The leaves are simple and entire, with elliptical hairless blades and slightly down-rolled margins. The lower surfaces have numerous tiny corky warts which appear as black spots on dried leaves. At one time considered to be a subspecies of ''Rhizophora mangle'', ''R. racemosa'' is now accepted as a full species, most easily distinguished by the fact that the stem of the axillary flowers branches up to si ...
