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 forest, 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 Mara ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...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 Cork (material), 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 b ...

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 ...

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
''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 pneumatophores 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 ῥίζα (''rhiza''), meaning "root," and φορός (''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 ...

Avicennia
''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 mari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
