Amapá Mangroves
The Amapá mangroves (NT1402) is an ecoregion along the Atlantic coast of the state of Amapá in Brazil. The low coastal plain has been formed from recent sedimentation, including sediments deposited by the rivers and sediments carried northward from the mouth of the Amazon River by strong currents and deposited by the tides. The extensive mangroves grow on the newly formed coastal mudflats and along the edges of estuaries. They merge into freshwater várzea flooded forests further inland. The ecoregion is generally well-preserved, although excessive extraction of natural resources including timber and shrimps is a concern. Location The Amapá mangroves cover an area of . They run along the Atlantic coast to the north of the mouth of the Amazon River up to the mouth of the Cassiporé River. The ecoregion is naturally fragmented, with patches of mangroves developing where the conditions are suitable for their growth. The mangroves form the coastal margin of the Marajó várzea ...

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] |
Calçoene
Calçoene () is a municipality located in the east of the state of Amapá in Brazil. It is located on the Atlantic Ocean in the Amazon jungle basin near French Guiana. Calçoene covers and has a population is 11,306. The name Calçoene is a corruption of "Calço N" (North Wedge, one of four mining zones defined by the Brazilian Government at the beginning of the 20th century). The city has the highest rainfall of any in Brazil, with an annual average of . Calçoene is noted for its ancient megalithic observatory, often referred to as the "Amazon Stonehenge". History The borders between French Guiana and Brazil were not clear, and in the 19th century, it was decided that the area between the Amazon and the Oyapock River was a neutral territory. Paul Quartier had a meeting with the village chiefs of Cunani and Carsewenne (nowadays: Calçoene) in 1885. In 1886, the Republic of Independent Guiana was founded by a group of French adventurers and two village chiefs with Cunani as t ...

Spartina Alterniflora
''Sporobolus alterniflorus'', or synonymously known as ''Spartina alterniflora'', the smooth cordgrass, saltmarsh cordgrass, or salt-water cordgrass, is a perennial deciduous grass which is found in intertidal wetlands, especially estuarine salt marshes. It has been reclassified as ''Sporobolus alterniflorus'' after a taxonomic revision in 2014, but it is still common to see ''Spartina alterniflora'' and in 2019 an interdisciplinary team of experts coauthored a report published in the journal ''Ecology'' supporting ''Spartina'' as a genus. It grows tall and has smooth, hollow stems that bear leaves up to long and wide at their base, which are sharply tapered and bend down at their tips. Like its relative saltmeadow cordgrass ''S. patens'', it produces flowers and seeds on only one side of the stalk. The flowers are a yellowish-green, turning brown by the winter. It has rhizoidal roots, which, when broken off, can result in vegetative asexual growth. The roots are an important f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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 ...

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
''Rhizophora'' is a genus of tropical mangrove trees, sometimes collectively called true mangroves. The most notable species is the red mangrove (''Rhizophora mangle'') but some other species and a few natural hybrids are known. ''Rhizophora'' species generally live in intertidal zones which are inundated daily by the ocean. They exhibit a number of adaptations to this environment, including pneutomatophores that elevate the plants above the water and allow them to respire oxygen even while their lower roots are submerged and a cytological molecular "pump" mechanism that allows them to remove excess salts from their cells. The generic name is derived from the Greek words ριζα (''rhiza''), meaning "root," and φορος (''phoros''), meaning "bearing," referring to the stilt-roots. The beetle '' Poecilips fallax'' is a common pest of these trees, especially '' Rhizophora mucronata'' and ''Rhizophora apiculata''. This beetle (related to carver beetles) lays its eggs in the ...
