Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have special adaptations to take in extra oxygen and to remove salt, which allow them to tolerate conditions that would kill most plants. 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. [6] => [[File:Acrostichum aureum? 00811.JPG|thumb|([[Acrostichum aureum]]) fern]] [7] => Mangroves are salt-tolerant trees, shrubs and ferns also called [[halophyte]]s, and are adapted to live in harsh coastal conditions.

Mangrove forests serve as vital habitats for a diverse array of aquatic species, offering a unique ecosystem that supports the intricate interplay of marine life and terrestrial vegetation. The saline conditions tolerated by various mangrove species range from brackish water, through pure seawater (3 to 4% salinity), to water concentrated by evaporation to over twice the salinity of ocean seawater (up to 9% salinity).{{cite web|url=http://www.nhmi.org/mangroves/phy.htm |title=Morphological and Physiological Adaptations: Florida mangrove website |publisher=Nhmi.org |access-date=8 February 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120204222702/http://www.nhmi.org/mangroves/phy.htm |archive-date=4 February 2012 }}{{cite book |last1=Primavera |first1=J.

''R. stylosa'' can grow even in saline water and the salt level in its roots is regulated within a certain threshold value through filtration. The root possesses a hierarchical, triple layered pore structure in the [[Epidermis (botany)|epidermis]] and most Na+ ions are filtered at the first sublayer of the outermost layer. The high blockage of Na+ ions is attributed to the high surface [[zeta potential]] of the first layer. The second layer, which is composed of [[Macroporous material|macroporous structures]], also facilitates Na+ ion filtration. The study provides insights into the mechanism underlying water filtration through [[halophyte]] roots and could serve as a basis for the development of a [[bio-inspired]] method of [[desalination]]. [62] => [63] => Uptake of Na+ ions is desirable for halophytes to build up [[osmotic potential]], absorb water and sustain [[turgor pressure]]. However, excess Na+ions may work on toxic element. Therefore, halophytes try to adjust salinity delicately between growth and survival strategies. In this point of view, a novel sustainable desalination method can be derived from halophytes, which are in contact with saline water through their roots. Halophytes exclude salt through their roots, secrete the accumulated salt through their aerial parts and sequester salt in [[senescent]] leaves and/or the bark.Tomlinson, P. The botany of mangroves.

Once germinated, the seedling grows either within the fruit (e.g. ''[[Aegialitis]]'', ''[[Avicennia]]'' and ''[[Aegiceras]]''), or out through the fruit (e.g. ''[[Rhizophora]]'', ''[[Ceriops]]'', ''[[Bruguiera]]'' and ''[[Nypa (genus)|Nypa]]'') to form a [[propagule]] (a ready-to-go seedling) which can produce its own food via [[photosynthesis]]. [70] => [71] => The mature propagule then drops into the water, which can transport it great distances. Propagules can survive desiccation and remain dormant for over a year before arriving in a suitable environment. Once a propagule is ready to root, its density changes so that the elongated shape now floats vertically rather than horizontally. In this position, it is more likely to lodge in the mud and root. If it does not root, it can alter its density and drift again in search of more favorable conditions.

However, a given mangrove swamp typically features only a small number of tree species. It is not uncommon for a mangrove forest in the Caribbean to feature only three or four tree species. For comparison, the tropical rainforest biome contains thousands of tree species, but this is not to say mangrove forests lack diversity.

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. Small environmental variations within a mangal may lead to greatly differing methods for coping with the environment. Therefore, the mix of species is partly determined by the tolerances of individual species to physical conditions, such as tidal flooding and salinity, but may also be influenced by other factors, such as crabs preying on plant seedlings.{{cite journal |last1=Cannicci |first1=S. |last2=Fusi |first2=M. |last3=Cimó |first3=F. |last4=Dahdouh-Guebas |first4=F. |last5=Fratini |first5=S. |title=Interference competition as a key determinant for spatial distribution of mangrove crabs |journal=BMC Ecology |date=2018 |volume=18 |issue=1 |pages=8 |doi=10.1186/s12898-018-0164-1 |pmid=29448932 |pmc=5815208 |doi-access=free |bibcode=2018BMCE...18....8C }} [399] => [400] => [[File:Nipa palms.jpg|thumb|Nipa palms, ''[[Nypa fruticans]]'', the only palm species fully adapted to the mangrove biome]] [401] => Once established, mangrove roots provide an oyster habitat and slow water flow, thereby enhancing sediment deposition in areas where it is already occurring.

About

Mangroves are a type of forest that grow in coastal areas, characterized by the presence of salt-tolerant plants called mangroves. The page describes their diverse distribution around the world, with notable concentrations in areas such as the Sundarbans in Bangladesh and the Florida Everglades in the United States. The article highlights the important ecological role of mangroves. Their complex root systems protect coastlines from erosion and storm damage, while also acting as nurseries for a wide variety of marine species. Mangroves are also highly efficient carbon sinks, helping to mitigate climate change by storing large amounts of carbon dioxide. The page explores the unique adaptations of mangroves to their challenging environment. These plants have developed mechanisms to tolerate high salinity levels, access oxygen in waterlogged soils, and filter salt from their systems. The article also discusses their reproductive strategies, including aerial prop roots and vivipary, where seeds germinate while still on the tree. The page delves into the human impacts on mangroves, including deforestation for urbanization, agriculture, and aquaculture. These activities result in the loss of important habitats, disruption of coastal ecosystems, and a decrease in biodiversity. The article also examines conservation efforts aimed at protecting and restoring mangrove forests and their associated benefits. In addition to describing the ecological and conservation aspects, the page also touches on the cultural significance of mangroves. They have been an integral part of coastal communities for centuries, providing resources such as timber, food, and traditional medicines. Overall, the Wikipedia page on mangroves provides a comprehensive and informative overview of these important ecosystems, covering their distribution, ecological functions, adaptations, human impacts, and conservation efforts.
