Gulf Of Fonseca
The Gulf of Fonseca (; ), a part of the Pacific Ocean, is a gulf in Central America, bordering El Salvador, Honduras, and Nicaragua. The waters of the gulf are shared among all three countries. History Fonseca Bay was discovered by Europeans in 1522 by Gil González Dávila, Gil González de Ávila, and named by him after his patron, Juan Rodríguez de Fonseca, Archbishop Juan Fonseca, the implacable enemy of Columbus. In 1849, E. G. Squier negotiated a treaty for the United States to build a canal across Honduras from the Caribbean Sea to the Gulf. Frederick Chatfield, the British Empire, British commander in Central America, was afraid the American presence in Honduras would destabilize the British Mosquito Coast, and sent his fleet to occupy El Tigre Island at the entrance to the Gulf. Shortly thereafter, however, Squier demanded the British leave, since he had anticipated the occupation and negotiated the island's temporary cession to the United States. Chatfield could o ...

ONUCA
ONUCA was a United Nations peacekeeping mission deployed in Central America in 1990 and 1991. ONUCA The United Nations Security Council formally created ONUCA ("United Nations Observer Group in Central America") when it approved Resolution 644 on 7 November 1989. The 625-person group, located in 33 regional bases, was responsible for halting cross-border infiltration and cutting support for rebels in the Central American region, and consisted of 260 unarmed military observers along with supporting technicians. Hemisphere countries involved in ONUCA included Spain, Sweden, Ireland, India, Venezuela, Canada, Argentina, Brazil, Ecuador and Colombia. ONUCA's initial mandate, composition and operational concept reflected the UN reluctance to get involved in internal conflicts. It was to be a verification and peace-observing mission, not a full-scale peacekeeping interposition mission, and certainly not peace-enforcement, although as events unfolded there were brief periods when Co ...

Laguncularia Racemosa
''Laguncularia'' is a genus of plants in the family Combretaceae. The only species in the genus is ''Laguncularia racemosa'', the white mangrove. 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 frui ...

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 northern Florida 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 oft ...

Rhizophora Mangle
''Rhizophora mangle'', also known as the red mangrove, is a salt-tolerant, small-to-medium sized evergreen tree restricted to coastal, estuarine ecosystems along the southern portions of North America, the Caribbean as well as Central America and tropical West Africa. Its viviparous "seeds", in actuality called propagules, become fully mature plants before dropping off the parent tree. These are dispersed by water until eventually embedding in the shallows. ''Rhizophora mangle'' grows on aerial prop roots, which arch above the water level, giving stands of this tree the characteristic "mangrove" appearance. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. The name refers to the red colour on the inner part of its roots when halved, so it does not display any red colour in its regular appearance. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree ''(Schinus terebinthifolius)''. The red mangrove itself is co ...

Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as ba ...

Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

Desde La Plaza De Amapala
Prepositions in the Spanish language, like those in other languages, are a set of connecting words (such as ''con'', ''de'' or ''para'') that serve to indicate a relationship between a content word (noun, verb, or adjective) and a following noun phrase (or noun, or pronoun), which is known as the object of the preposition. The relationship is typically spatial or temporal, but prepositions express other relationships as well. As implied by the name, Spanish "prepositions" (like those of English) are positioned ''before'' their objects. Spanish does not place these function words ''after'' their objects, which would be postpositions. Spanish prepositions can be classified as either "simple", consisting of a single word, or "compound", consisting of two or three words. The prepositions of Spanish form a closed class and so they are a limited set to which new items are rarely added. Many Spanish school pupils memorize the following list: ''a, ante, bajo, cabe, con, contra, de, des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
