Madagascar Lowland Forests
The Madagascar lowland forests or Madagascar humid forests are a tropical and subtropical moist broadleaf forests, tropical moist broadleaf forest ecoregion found on the eastern coast of the island of Madagascar, home to a plant and animal mix that is 80 to 90% endemic, with the forests of the eastern plain being a particularly important location of this endemism. They are included in the Global 200 list of outstanding ecoregions. Geography The ecoregion constitutes a narrow strip of lowland forests between Madagascar's east coast and the mountainous central highlands, from sea level to elevation. It covers an area of approximately . The ecoregion is under the direct influence of the oceanic trade winds, which maintain a warm, humid climate; rainfall is above 2,000 mm per year and can reach up to 6,000 mm on the Masoala peninsula. The lowland forests extend from Marojejy in the north to the southeast corner of the island. At the northern edge of ecoregion around Vohemar, the moi ...

Masoala National Park
Masoala National Park, in northeast Madagascar, is the largest of the island's protected areas. Most of the park is situated in Sava Region and a part in Analanjirofo. Created in 1997, the park protects 2,300 square kilometres of rainforest and 100 square kilometres of marine parks. The Masoala Peninsula is exceptionally diverse due to its large size, and variety of habitats. Altogether, the park protects tropical rainforest, coastal forest, flooded forest, marsh, and mangrove. Three marine parks protect coral reefs and a dazzling array of marine life. Climate This is an exceptionally wet area of Madagascar. The driest part of the year is from September to December. As the park is accessible only by a three-hour boat journey, the cyclone season (January to March) is best avoided. Flora and fauna There are ten lemur species, including the red ruffed lemur, which is native to the peninsula. The island reserve of Nosy Mangabe is one of the best sites in Madagascar to try to glim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trade Winds
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries. They enabled colonial expansion into the Americas, and trade routes to become established across the Atlantic Ocean and the Pacific Ocean. In meteorology, they act as the steering flow for tropical storms that form over the Atlantic, Pacific, and southern Indian oceans and make landfall in North America, Southeast Asia, and Madagascar and East Africa. Shallow cumulus clouds are seen within trade wind regimes and are capped from becoming taller by a trade wind inversion, which is caused by descending air aloft from within the subtropical ridge. The weak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albizia
''Albizia'' is a genus of more than 160 species of mostly fast-growing subtropical and tropical trees and shrubs in the subfamily Mimosoideae of the family Fabaceae. The genus is pantropical, occurring in Asia, Africa, Madagascar, America and Australia, but mostly in the Old World tropics. In some locations, some species are considered weeds. They are commonly called silk plants, silk trees, or sirises. The obsolete spelling of the generic name – with double 'z' – is still common, so the plants may be called albizzias. The generic name honors the Italian nobleman Filippo degli Albizzi, who introduced ''Albizia julibrissin'' to Europe in the mid-18th century. Some species are commonly called mimosa, which more accurately refers to plants of genus ''Mimosa''. Species from southeast Asia used for timber are sometime termed East Indian walnut. Description They are usually small trees or shrubs with a short lifespan, though the famous ''Samán del Guère'' near Maracay in Venez ...

Symphonia (plant)
''Symphonia'' is a genus of tropical woody plants, specifically trees in the family Clusiaceae. The genus has its diversity center in Madagascar and one species (''Symphonia globulifera'') disjunct in the Afrotropic and the Neotropic in the Amazon Rainforest. Because of this particular distribution pattern, the origin of the genus is controversial: two hypotheses have been proposed, one suggesting an Amazon origin, the other a Madagascar origin. Species , The Plant List accepts 15 species: *'' Symphonia eugenioides'' Baker *'' Symphonia fasciculata'' (Noronha ex Thouars) Vesque *''Symphonia globulifera ''Symphonia globulifera'', commonly known as boarwood, is a timber tree abundant in Central America, the Caribbean, South America and Africa.

Diospyros
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as " God's pear" and " Jove's fire". The genus is a large one a ...

Rain Shadow
A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side. Evaporated moisture from water bodies (such as oceans and large lakes) is carried by the prevailing onshore breezes towards the drier and hotter inland areas. When encountering elevated landforms, the moist air is driven upslope towards the peak, where it expands, cools, and its moisture condenses and starts to precipitate. If the landforms are tall and wide enough, most of the humidity will be lost to precipitation over the windward side (also known as the ''rainward'' side) before ever making it past the top. As the air descends the leeward side of the landforms, it is compressed and heated, producing foehn winds that ''absorb'' moisture downslope and cast a broad "shadow" of dry climate region behind the mountain crests. This climate typically takes the form of shrub–steppe, xeric shrublands or even deserts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Dry Deciduous Forests
The Madagascar dry deciduous forests represent a tropical dry forest ecoregion situated in the western and northern part of Madagascar. The area has high numbers of endemic plant and animal species but has suffered large-scale clearance for agriculture. They are among the world's richest and most distinctive dry forests and included in the Global 200 ecoregions by the World Wide Fund. The area is also home to distinctive limestone karst formations known as tsingy, including the World Heritage Site of Bemaraha. Geography There are two separate areas within the ecoregion: the western side of Madagascar from the Ampasindava peninsula in the north to Belo-sur-Tsiribihina and Maromandia in the south (this is most of Mahajanga Province); and the northern tip of the island (apart from the high areas of Amber Mountain). Geological substrate is varied and includes the tsingy limestone massifs. These dry deciduous forests span the coastal plain with its limestone plateaus emanatin ...
