The coastal zone of Mexico encompasses some 10,000 km along the Pacific Ocean, the Gulf of California, the Gulf of Mexico, and the Caribbean. There are further concerns around the sources of feed both in terms of crop-based feed production and in terms of using feed originating from wild-caught fish. Mangrove forests grow in the tidal lagoons of tropical coastlines and they could actually benefit from climate change. 1. The total annual rainfall in a Mangrove Forest varies from 1000 to 1500 mm. The main ecological role of primary producers is photosynthesis. Shrubs may often be salt-tolerant. Every year the blossoms of bulbous plants lay short-lived carpets of colour.

Flores-Verdugo, ... P. Ramirez-Garcia, in, Coastal Plant Communities of Latin America, Mangrove systems, also known as tidal forest or, Adaptation of Plants to Adverse Chemical Soil Conditions, Marschner's Mineral Nutrition of Higher Plants (Third Edition). Aquaculture production makes a significant and growing contribution to global food security. Urban Development Urban development of areas in and near mangroves results in the destruction of this habitat as well as other associated wetland habitats. Indeed, there is a Red List for rust fungi in Wales, UK. Mangrove species found on the coast of Mexico are the red mangrove Rhizophora mangle L., the white mangrove Laguncularia racemosa (L.) Gaerth, the black mangrove Avicennia germinans (L.) L., and the button mangrove Conocarpus erecta L. (Pennington and Sarukhan, 1969). The end of January came to a sad close in Cancun, Mexico this year when the federal government authorized the destruction of one of the last mangrove swamps located in the area. Mangroves are tropical plants, killed by freezing temperatures. Mangroves can reach far upstream from the sea, wherever a wedge of heavier sea water can creep over the bottom, to raise the salinity of the surface mud. From: Freshwater Ecology (Second Edition), 2010, Friedhelm Göltenboth, Sabine Schoppe, in Ecology of Insular Southeast Asia, 2006. 10.6). Mangroves develop in tropical climate regions with average temperatures above 20°C. Currently out of the 230 Mio ha of irrigated agricultural land worldwide, around 45 Mio ha are salt affected (Athar and Ashraf, 2009). Molecular biological studies have recently shed light on some mechanisms involved in plant salt tolerance, and this may translate into more rapid selection of salt-tolerant genotypes or even the development of suitable transgenic cultivars in the future (Munns, 2005). Over much of the interior of Tanzania, in areas of reduced rainfall and poorer soils, a light-canopied, sustained woodland called Miombo forest rises above a rather scrawny ground layer. Often vines, such as rubber vines and morning-glory, climb over mangroves, especially at swamp edges. While shrubs may die from inadequate moisture, they are little affected by the rare fires that occur. Animals in the Swamps The intertidal existence to which these trees are adapted represents the major limitation to the number of species able to thrive in their habitat. Mangrove swamps are difficult to explore. The coasts are perhaps the most neglected biogeographic zone of India, mainly because charismatic species are not found there. The use of poor quality irrigation water is one reason for an increasing salinization of agricultural land, mainly in arid or semi-arid areas. Mangrove forests are usually hot and humid, due to the fact that … (B) Mexican climatic regions with tropical depressions and hurricanes from 1980 to 1987 (dots). Buttonwoods usually occur in areas above high tide. 1B). Classification and zonation of mangrove communities can be based on either structural attributes of mangrove forests (Specht, 1970), physiogeographic characteristics (Lugo and Snedaker, 1974), or coastal geomorphology (Thom, 1982). Arid climate (vertically hatched), semi-arid climate (not hatched), subhumid climate (diagonally hatched) and humid climate (horizontally hatched). Mangrove trees are facultative halophytes, found between sub- and supratidal areas on tropical and subtropical coast. Sometimes the roots are covered with a variety of sea creatures and can be as colorful as reefs. With few exceptions, the mangroves of Mexico's west coast are less extensive, structurally less developed, and more discontinuous than those of the Gulf of Mexico (Pennington and Sarukhan, 1969). Mangrove forests are incredibly important ecosystems. The area along the coast, however, is almost always foggy, and succulent shrubs (such as aloes) manage to survive on this moisture. Hartig, in Encyclopedia of Soils in the Environment, 2005. They require warm saline water—hence their distribution along tropical coastlines. The Pacific coast has a high-relief physiography, cliffed or narrow shorelines, and steeply inclined coastal plains (reduced intertidal area) bordered by mountain ranges with elevations of up to 3300 m. The climate of the west coast is drier and colder than that of the Gulf of Mexico. Thorn woodland displays a predominance of xerophytic, sometimes succulent or semisucculent trees, such as acacia, Commiphora (the myrrh tree), or Boscia (an evergreen hard-leaved tree). The Rhizophora zone: Rhizophora forests develop behind the pioneering species. Areas where mangroves occur include estuaries and marine shorelines.. Estuarine scrub–shrub wetlands: These wetlands contain woody vegetation such as marsh elder or high-tide bush. Dredging, land reclamation, garbage and sewage dumping are all disturbances that can have significant impacts on mangroves near populated areas. 2012 ). Many seaweeds live in rocky intertidal communities, since they cannot follow the water when the tide goes out, intertidal seaweeds are subjected to the stress associated with exposure and weather conditions. In these areas, there are usually relatively high temperatures (70-80 degrees Fahrenheit) and significant amounts of precipitation (4.5 meters). A relatively luxuriant shrub layer, often forming dense thickets, is found in conjunction with succulents, such as aloes, Sansevieria (a fibrous species), and Adenium, or desert rose (a succulent shrub with smooth gray bark, a huge water-storing base, and beautiful red or pink flowers), and smaller euphorbias. The mixed zone: In this zone, species like Heritiera littoralis, Excoecaria agallocha, Xylocarpus granatum, and Osbornia octodonta may occur. Toward the margins of the tropics, the vegetation cover becomes lower and thinner as the fluctuating transition to desert vegetation ensues. Mangrove swamps are easiest to explore on foot at low tide. Seaweeds can attach to a variety of artificial substrata, eg, logs, ropes, tires, bricks, and plastics (Fig. Vera-Herrera, in. The low shrubs that grow there can be divided into two groups: woody plants, such as species of Acacia and Pentzia and the saltbush (Atriplex); and succulents, including aloes, euphorbias, and Mesembryantheum. It should be emphasized that the forest composition and expansion of mangroves differs from place to place depending partly on the physiography of the coast and the presence and absence of streams. To prevent salinization, the accumulated salts have to be removed periodically by leaching and drainage. Mangrove forests are incredibly important ecosystems. The government plans to add 10,000 hectares (24,700 acres) of rehabilitated mangrove swamps to the island’s current mangrove cover of 15,670 … All of this has implications for the ecological management of this ecosystem, which is an area subject to oil exploitation and intense fishery activities. The occurrence of the bunched and thorny desert date (Balanites) seems to accompany land impoverishment. Often they form nearly impenetrable stands, for which the easiest access is by sea. The southern margin of the Sahara—roughly between the latitudes of 15° and 20°—is called the Sahel (Arabic: Sāḥil; meaning “shore” or “edge”), the word being extended by implication to comprehend the fluctuating margins of the great sand seas of the Sahara to the north. In addition, they provide shelter and reproductive grounds for fish, invertebrates, birds, and mammals. Globally, however, destruction of mangroves is progressing faster than reintroduction. In countries like Bangladesh, removal of this buffering zone has led to intensified coastline inundation and erosion from tropical storms. In a study from 2014, mangrove forests were found to provide ecosystem services (benefits to humans) valued at $194,000 per hectare annually.Today is International Mangrove Day and here are just a few reasons we should care about mangroves – and invest in protecting them:. Mangrove forests have more than doubled in expanse on the northern end of Florida's East Coast, likely because climate change has led to fewer cold snaps, a new study finds. Mangrove forests on the western coast of Madagascar support a number of endemic bird species that are endangered. During the Vietnam war, spraying of herbicides on mangrove swamps defoliated and destroyed as much as 100 000 hectares. Mangrove swamps (see Section 8.7) suffer from many of the same environmental disturbances that are experienced by estuaries. Because of periodic burning, tall grasses have become dominant over large expanses of plateau land, which sometimes contains few, if any, of its original trees. Many, such as the Spartina alterniflora intertidal marshes of the northeastern USA, formed within the last 4000–7000 years as the postglacial rise in sea level slowed. Only 6.9 percent of mangrove forests are protected by law. National Museum of Natural History, mangrove swamps ( see Section 8.7 ) suffer many.
