Mangrove plants require a number of physiological adaptations to overcome the problems of low environmental oxygen levels, high salinity, and frequent tidal flooding.Each species has its own solutions to these problems; this may be the primary reason why, on some shorelines, mangrove tree species show distinct zonation.
Avicennia germinans, the black mangrove, [3] 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.
A mangrove is a shrub or tree that grows mainly in coastal 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.
Black mangrove flower Excreted salt on the underside of a mangrove leaf. Avicennia germinans — black mangrove; Black mangrove trees grow to a heights of 133 feet and average 66 feet. They are characterized by vertically erect aerating branches (pneumatophores) extending up to 20 cm above the soil. The bark is dark and scaly and the upper ...
The Mesoamerican Gulf-Caribbean mangroves ecoregion (WWF ID: NT1403) covers the series of disconnected mangrove habitats along the eastern coast of Central America.These salt-water wetlands are found in river deltas, lagoons, and low-lying areas facing the Gulf of Mexico and Caribbean Sea, from Tampico, Mexico to central Panama.
The Northern Mesoamerican Pacific Mangroves are composed of two main mangrove areas located on the Pacific Coast and the Gulf of California Coast. Magdalena Bay is the largest area on the Pacific coast, along with San Ignacio Lagoon and Ojo de Liebre Lagoon, and on Cedros Island and Guadalupe Island off the coast.
Mangroves extend along the Pacific coast south to 5°32' at the estuary of the Piura River in the north of Peru. South of that the cold Humboldt Current causes high soil salinity and very arid conditions, with hardly any fresh water streams. This is an inhospitable environment for mangroves, particularly during El Niño years. [12]
The Northern Dry Pacific Coast mangroves ecoregion (WWF ID: NT1425) covers the mangrove habitats in a series of sites along the Pacific Ocean coast of Guatemala and El Salvador. This part of Central America is relatively dry compared to higher elevations or more southerly areas, so the wetland mangroves serve as a refuge for animals of the ...
