Xylocarpus is a genus of plants in the mahogany family Meliaceae.It contains 3 described species, all of which are mangroves. [1] [2] The native range of the genus is the coasts of the Indian Ocean, Southeast Asia and the western Pacific Ocean. [3]
Mangroves in general are under threat from coastal development and from harvesting, and another threat is global warming and the consequent rise in sea levels. Xylocarpus granatum is a common species of mangrove with a very wide range, and it is probably not declining at a sufficient fast rate to be included in any threatened category.
The nature of these deposits depends on the environment and the types of mangroves involved. Termites process fallen leaf litter, root systems and wood from mangroves into peat to build their nests. [35] Termites stabilise the chemistry of this peat and represent approximately 2% of above ground carbon storage in mangroves. [35]
They are primarily found in mangroves but have also made appearances in salt marshes, rotten wood, man-made structures, [2] and free-hanging aerial roots. [ 6 ] [ 5 ] Though the mangrove and the isopod have a non- symbiotic relationship, there are both consequences and advantages for the mangroves and the surrounding environment. [ 6 ]
The fruits are button-like (from which the common names derive), 5–8 mm (0.20–0.31 in) diameter, with no petals; they are produced in stalked panicles of 35-56 flowers. The fruit is a cluster of red to brown, small scaly, two-winged cone-like seeds, 5–15 mm (0.20–0.59 in) long. The seed heads burst when ripe, and the seeds are dispersed ...
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.
These wood structures keep the xylem sap in high tension to absorb water, resulting in a high sodium chloride concentration and high osmatic potential. [9] Terrestrial species in Rhizophoreae could not survive in the intertidal zone because the osmatic potential in the sea water would be much higher than that in the xylem sap of the tree ...
It seems to be more tolerant of inundation than other mangrove species and often forms an evergreen fringe to mangrove areas. It sometimes occurs as a pure stand or may grow with Rhizophora apiculata. [6] The red mangrove is a protected tree in South Africa. [7]
