Madagascar Mangroves
Madagascar mangroves are a coastal ecoregion in the mangrove forest biome found on the west coast of Madagascar. They are included in the WWF's Global 200 list of most outstanding ecoregions. Geography Mangrove swamps are located in flat coastal areas where the ocean tides wash saltwater high into the mouths of rivers which are bringing nutrient-rich soil down to the coast. For mangroves to thrive, there needs to be some natural feature such as coral reefs to shelter the coast from ocean storms and monsoons. In Madagascar, they are mostly found on the more sheltered west coast along the Mozambique Channel, where they stretch along roughly of coastline. The largest areas are in the estuaries of the Betsiboka River (in Bombetoka Bay near the city of Mahajanga), Besalampy, the Mahajamba and South Mahavavy river, and near Maintirano. The climate is warm all along the coast but more humid in the north. Flora The mangrove trees found in Madagascar are mainly ''Rhizophora mucronat ...

Biome
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its c ...

Mahajanga
Mahajanga (French: Majunga) is a city and an administrative district on the northwest coast of Madagascar. The city of Mahajanga (Mahajanga I) is the capital of the Boeny Region. The district (identical to the city) had a population of 220,629 in 2013. Mahajanga is a tourist destination for Malagasy tourists and international travelers, with beaches, a coconut-lined boardwalk ("Le Bord", short for "Bord de la mer" or sea-side), and eight months of hot, virtually rain-free weather. City Mahajanga is a seaport, the second most important one in Madagascar after Toamasina. The marine terminal accommodates containerships and small (150 gross ton) general cargo freighters. Because of limited water depth at the wharf, only small ships can call at the terminal. Deeper-draft ships anchor off the terminal and transfer cargoes to and from barges, which move it to and from the terminal. Severe storms during December 2006 damaged the bulkhead, allowing water to flow in and wash backfi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombetoka Bay
Bombetoka Bay is a bay on the northwestern coast of Madagascar near the city of Mahajanga, where the Betsiboka River flows into the Mozambique Channel. Numerous islands and sandbars have formed in the estuary from the large amount of sediment carried in by the Betsiboka River and have been shaped by the flow of the river and the push and pull of tides. Along coastlines and on the islands, the vegetation is predominantly mangrove forests. In fact, Bombetoka Bay is home to some of Madagascar's largest remaining communities of mangroves, which provide shelter for diverse mollusk and crustacean communities, as well as habitat for sea turtles, birds, and dugongs. Along the northwest coast of Madagascar, mangroves and coral reefs partner to create dynamic, diverse coastal ecosystems. The mangrove forests capture river-borne sediment that would smother coastal reefs, while reefs buffer the mangroves from pounding surf. Near water, shrimp and rice farming are common, while coffee plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betsiboka River
Betsiboka River is a long river in central-north Madagascar. It flows northwestward and empties to Bombetoka Bay, forming a large river delta, delta. It originates to the east of Antananarivo. The river is surrounded in mangroves. The river is distinctive for its red-coloured water, which is caused by river sediments. The river carries an enormous amount of reddish-orange silt to the sea. Much of this silt is deposited at the mouth of the river or in the bay. It is dramatic evidence of the catastrophic erosion of northwestern Madagascar. Removal of the native forest for cultivation and pastureland during the past 50 years has led to massive annual soil losses approaching 250 metric tonnes per hectare (112 tons per acre) in some regions of the island, the largest amount recorded anywhere in the world. Several fish species are Endemism, endemic to the river basin, including the three cichlids ''Kotso, Paretroplus petiti'', ''Paretroplus tsimoly, P. tsimoly'' and ''Damba mipentina, P ...

Mozambique Channel
The Mozambique Channel (french: Canal du Mozambique, mg, Lakandranon'i Mozambika, pt, Canal de Moçambique) is an arm of the Indian Ocean located between the Southeast African countries of Madagascar and Mozambique. The channel is about long and across at its narrowest point, and reaches a depth of about off the coast of Mozambique. A warm current, the Mozambique Current, flows in a southward direction in the channel, leading into the Agulhas Current off the east coast of Southern Africa. Extent The International Hydrographic Organization (IHO) defines the limits of the Mozambique Channel as follows: ::''On the North.'' A line from the estuary of the River Rovuma () to Ras Habu, the northernmost point of Ile Grande Comore, the northernmost of the Comore (Comoro) Islands, to Cap d'Ambre (Cape Amber), the northern extremity of Madagascar (). ::''On the East.'' The west coast of Madagascar. ::''On the South.'' A line from Cap Sainte-Marie, the southern extremity of Mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area.

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...
