Tsiribihina River
The Tsiribihina is a river of western Madagascar. The main tributaries are the Mahajilo, Manandaza, Mania, and Sakeny rivers. Its basin has an area of 49,800 km2. 7,025 km2 is in the basin of the Sakeny River, 14,500 km2 in that of the Mahajilo River, and 18,565 km2 in that of the Mania River. The headwaters are on Madagascar's Central Highlands. The tributary streams flow generally westwards except for the Sakeny, which flows northwards. As they leave the highlands and enter the north–south running Betsiriry Plain, the tributary rivers converge to form the Tsiribihina - the Mahajilo and Manandaza from the north, and the Mania and Sakeny from the south. There are extensive seasonal wetlands and shallow lakes where the rivers converge on the plain. The rich alluvial soils of the Betsiriry Plain make it one of the most suitable regions for agriculture in western Madgagascar.Vololona, Mireille & Kyotalimye, Miriam & Thomas, Timothy & Waithaka, Michael.

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Bruguiera
''Bruguiera'' is a plant genus in the family Rhizophoraceae. It is a small genus of five mangrove species and three hybrids of the Indian and west Pacific Ocean region, its range extending from East Africa and Madagascar through coastal India, Sri Lanka and Southeast Asia to northern Australia, Melanesia and Polynesia. It is characterised by calyces with 8-16 lanceolate, pointed lobes, 16-32 stamens, explosive release of pollen, and viviparous propagules. It is named in honour of French explorer and biologist Jean Guillaume Bruguière (1750–1798). Recently, the eighth taxa of Bruguiera, ''B. × dungarra'' (a previously undescribed hybrid species between '' B. exaristata'' and '' B. gymnorhiza'') was recognised as occurring in northern Australia.

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Menabe Antimena
Menabe Antimena is a protected area in Menabe region of western Madagascar. Menabe Antimena is on the west coast of Madagascar, south of the Mania River. It covers an area of dry forest, succulent woodland, mangroves, and secondary grassland and scrub. It includes the northern portion of the Kirindy Forest and the Avenue of the Baobabs. Large areas have been illegally logged, burned, and converted to maize fields, which threatens the area's wildlife, including the critically endangered Madame Berthe's mouse lemur (''Microcebus berthae''), the smallest primate in the world. Tsiribihina mangroves The Tsiribihina mangroves extend along the coast around the mouth of the Tsiribihina River. The mangroves are mostly within the reserve, with the portion north of the river outside it. There are about 20,000 hectares of mangroves, 8.5% of Madagascar's mangroves by area, along with lagoons, marshes, sandbanks, salt flats, and mud flats. About 40,000 waterbirds from 44 species live in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Fish Eagle
The Madagascar fish eagle (''Haliaeetus vociferoides'') or Madagascar sea-eagle (to distinguish it from the ''Ichthyophaga'' fishing-eagles), is a large bird of prey in the family Accipitridae which also includes many other diurnal raptors such as kites, buzzards and harriers. It is endemic to the coastal strip in the northwest of Madagascar. It is about long and has a pale brown head, dark brown body and white tail. The Madagascan fish eagle has been suffering from a declining population and is threatened by habitat destruction and persecution, and the International Union for Conservation of Nature has rated its conservation status as being " critically endangered". Description The Madagascar fish eagle is a medium-sized sea eagle, long and with a wingspan of . The body and wings are dark brown, with a pale brown head and a white tail; the bill is blackish with a paler base, and the legs are pale grey. Males weigh , while the slightly larger females weigh .

White-backed Duck
The white-backed duck (''Thalassornis leuconotus'') is a waterbird of the family Anatidae. It is distinct from all other ducks, but most closely related to the whistling ducks in the subfamily Dendrocygninae, though also showing some similarities to the stiff-tailed ducks in the subfamily Oxyurinae. It is the only member of the genus ''Thalassornis''. Description These birds are well adapted for diving. On occasions they have been observed to stay under water for up to half a minute. They search especially for the bulbs of waterlilies, but also seeds and leaves of waterlilies and other water plants and the young feed on lake flies larvae as well. From danger, they also escape preferentially by diving; hence, the namesake white back is hardly visible in life.

Bernier's Teal
Bernier's teal (''Anas bernieri''), also known as the Madagascar teal, is a species of duck in the genus ''Anas''. It is endemic to Madagascar, where it is found only along the west coast. Part of the "grey teal" complex found throughout Australasia, it is most closely related to the Andaman teal. Taxonomy The Bernier's teal was first described by the German ornithologist Gustav Hartlaub in 1860 under the binomial name ''Querquedula bernieri''. It is one of many dabbling ducks in the genus ''Anas''. It is one of the "grey teals", a group of related ducks found across Australasia. DNA studies suggest that it may have been a sister species with Sauzier's teal (which was found on the nearby islands of Mauritius and Réunion until it became extinct). Studies further suggest that its closest living relative is the Andaman teal, and confirm that it is related to the gray teal. There are no subspecies. The duck's common and species names both commemorate Chevalier Bernier, a Frenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.''

Eichhornia
''Eichhornia'', commonly called water hyacinths, was a polyphyletic genus of the aquatic flowering plants family Pontederiaceae. Since it was consistently recovered in three independent lineages, it has been sunk into ''Pontederia'', together with '' Monochoria''. Each of the three lineages is currently recognized as subgenera in ''Pontederia'': * ''Pontederia'' subg. ''Cabanisia'', which includes '' P. meyeri'', '' P. paniculata'' (the Brazilian water hyacinth), and '' P. paradoxa'' * ''Pontederia'' subg. ''Oshunae'', which includes the common water hyacinth, '' P. crassipes'' * ''Pontederia'' subg. ''Eichhornia'', which includes '' P. azurea'', '' P. diversifolia'', '' P. heterosperma'', and '' P. natans'' ''Pontederia'' subg. ''Eichhornia'' is pantropical, centered in South America but with '' P. natans'' being endemic to continental Africa and Madagascar. The other three species are restricted to the Neotropics. It was named in honour of , an early-19th-century Prussian min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
