Bahia Mangroves
The Bahia mangroves is a tropical ecoregion of the mangroves biome, and the South American Atlantic Forest biome, located in Northeastern Brazil. Its conservation status is considered to be critical/endangered due to global climate change and other factors. Geography The Bahia mangrove habitats occupy minor bays, estuaries, and river inlets along the coast from Recôncavo on Todos os Santos Bay in Bahia State; north to the Doce River in Espírito Santo State. The total ecoregion comprises 2,100 square kilometers (800 square miles) of shallow coastal waters and land. Flora Mangrove tree species include typical Atlantic Ocean tropical mangrove species, the red mangrove (''Rhizophora mangle'') of the Rhizophoraceae, the black mangrove (''Avicennia germinans'') of the Acanthaceae, and the white mangrove (''Laguncularia racemosa'') of the Combretaceae family.

Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of 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 trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Inlet
An inlet is a (usually long and narrow) indentation of a shoreline, such as a small arm, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea. Overview In marine geography, the term "inlet" usually refers to either the actual channel between an enclosed bay and the open ocean and is often called an "entrance", or a significant recession in the shore of a sea, lake or large river. A certain kind of inlet created by past glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes. Multi-arm complexes of large inlets or fjords may be called sounds, e.g., Puget Sound, Howe Sound, Karmsund (''sund'' is Scandinavian for "sound"). Some fjord-type inlets are called canals, e.g., Portland Canal, Lynn Canal, Hood Canal, and some are channels, e.g., Dean Channel and Douglas Channel. Tidal amplitude, wave intensity, and wave direction are all factors that in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ucides Cordatus
''Ucides cordatus'', the swamp ghost crab (or ''caranguejo-uçá'' in Portuguese), is one of two species of crabs in the genus ''Ucides''. This species of crab is native to many coasts off of the western Atlantic Ocean. It has been found to be native to areas as far as Florida, to as southern as Uruguay. ''U. cordatus'' is especially noteworthy in the country in Brazil as it plays important roles in the economy and food resources at Brazil’s Atlantic borders. Like most other crabs, ''U. cordatus'' has two distinct pinchers for different uses. Its left sharp pincher functions to cut and feed and the other pincher, is much larger and used to crush objects. It has an oval back with a very unique color scheme. ''U. cordatus'' is one of many animals that have sexual dimorphism. Most noticeably, female crabs are larger than their male counter parts. Males have a flatter oval shaped back with a distinct light blue in the middle with a beige white encompassing its back. On the other h ...

Benthic Macrofauna
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertidal ...

Combretaceae
The Combretaceae, often called the white mangrove family, are a family of flowering plants in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in ca 10 genera. The family includes the leadwood tree, ''Combretum imberbe''. Three genera, ''Conocarpus'', ''Laguncularia'', and ''Lumnitzera'', grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from ''Terminalia ivorensis''. The commonly cultivated ''Quisqualis indica'' is now placed in the genus ''Combretum''. Many plants in the Quisqualis species contain the Non-proteinogenic amino acid excitotoxin Quisqualic acid, a potent AMPA agonist.Excitotoxic cell death and delayed rescue in human neurons derived from NT2 cells, M Munir, L Lu and P Mcgonigl, Journal of Neuroscience, Vol 15, 7847–7860 White mangroves The family name comes from the type genus ''Combretum''; it also ...

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 ...

Acanthaceae
Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests. Description Plants in this family have simple, opposite, decussated leaves with entire (or sometimes toothed, lobed, or spiny) margins, and without stipules. The leaves may contain cystoliths, calcium carbonate concretions, seen as streaks on the surface. The flowers are perfect, zygomorphic to nearly actinomorphic, and arranged in an inflorescence that is either a spike, raceme, or cyme. Typically, a colorful bract subtends ea ...

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 ...

Rhizophoraceae
The Rhizophoraceae is a family of tropical or subtropical flowering plants. It includes around 147 species distributed in 15 genera.Setoguchi, H., Kosuge, K., & Tobe, H. (1999). Molecular Phylogeny of Rhizophoraceae Based on rbcL Gene Sequences. ''Journal of Plant Research'', ''112''(4), 443–455. https://doi.org/10.1007/PL00013899 Under the family, there are three tribes, Rhizophoreae, Gynotrocheae, and Macarisieae. Even though Rhizophoraceae is known for its mangrove members, only the genera under Rhizophoreae grow in the mangrove habitats and the remaining members live in inland forests. Taxonomy This family is now placed in the order Malpighiales, though under the Cronquist system, they formed an order in themselves (Rhizophorales).Juncosa, A. M., & Tomlinson, P. B. (1988).

Rhizophora Mangle
''Rhizophora mangle'', the red mangrove, is distributed in Estuary, estuarine ecosystems throughout the tropics. Its Vivipary, 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 root#Aerial roots as supports, 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. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree ''(Schinus terebinthifolius)''. The red mangrove itself is considered an invasive species in some locations, such as Hawaii, where it forms dense, monoculture, monospecific thickets. ''R. mangle'' thickets, however, provide nesting and hunting habitat for a diverse array of organisms, including fish, birds, and cro ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
