Alaotra
Lake Alaotra ( mg, farihin' Alaotra, ; french: Lac Alaotra) is the largest lake in Madagascar, located in Alaotra-Mangoro Region and on the island's northern central plateau. Its basin is composed of shallow freshwater lakes and marshes surrounded by areas of dense vegetation. It forms the center of the island's most important rice-growing region. It is a rich habitat for wildlife, including some rare and endangered species, as well as an important fishing ground. Lake Alaotra and its surrounding wetlands cover , and include a range of habitats, including open water, reedbeds, marshes, and rice paddies. The lake itself covers . Lake Alaotra was declared a wetland of international importance under the international Ramsar Convention on February 2, 2003. The longfin tilapia (''Oreochromis macrochir'') was introduced into Lake Alaotra from the mainland in 1954 and proliferated quickly. By 1957, it provided 46% of the catch, perhaps because it was moving into an empty ecological niche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaotra Grebe
The Alaotra grebe (''Tachybaptus rufolavatus''), also known as Delacour's little grebe or rusty grebe, is an extinct grebe that was endemic to Lake Alaotra and its surrounding lakes in Madagascar. Description The grebe was about long. Its ability to fly long distances was restricted because of its small wings. Ecology and behavior The Alaotra grebe fed mostly on fish, although insects were found in the stomachs of a few specimens.Safford 2013, p. 111 Its hefty bill was considered typical of a piscivorous grebe. The breeding behavior of the Alaotra grebe was largely undocumented. Because little and Alaotra grebes were able to successfully pair off, it is suspected that courtship and pair formation took place in December, while most breeding activity took place between January and March. However, based off some observations of older juveniles with their mothers in late May and early June 1929, it is suspected that some egg laying must have occurred in April to June. Otherwise, t ...

Lac Alaotra Gentle Lemur
The Lac Alaotra bamboo lemur (''Hapalemur alaotrensis''), also known as the Lac Alaotra gentle lemur, Alaotran bamboo lemur, Alaotran gentle lemur, Alaotra reed lemur, or locally as the ', is a bamboo lemur. It is endemic to the reed beds in and around Lac Alaotra, in northeast Madagascar. It is about long, with a similar length tail, and is a brownish-gray colour. It is the only bamboo lemur to live in and feed on Cyperus papyrus, papyrus reeds, and other reeds and grasses, and some authorities argue that it should be regarded as a subspecies of the eastern lesser bamboo lemur (''Hapalemur griseus''). The population of this lemur has been declining because of habitat destruction and the International Union for Conservation of Nature has rated it as being "critically endangered". Taxonomy The classification of the'' bandro'' is disputed, with some classifying it as a subspecies of ''Hapalemur griseus'', while others see it as a separate species.

Madagascar Pochard
The Madagascar pochard or Madagascan pochard (''Aythya innotata''; mg, Fotsy maso, Onjo) is an extremely rare diving duck of the genus ''Aythya''. Thought to be extinct in the late 1990s, specimens of the species were rediscovered at Lake Matsaborimena near Bemanevika in Madagascar in 2006. By 2017, a captive breeding program had produced a population of around 90 individuals. The birds were reintroduced to the wild in December 2018. The Madagascar pochard feeds mainly on aquatic insects, unlike other diving ducks in the same genus, Aythya. Ducklings begin making short dives at around 14 days old, before which they feed on the surface. Taxonomy The Madagascar pochard was largely overlooked by scientists in the 19th century, as those that saw it assumed they were seeing ferruginous ducks instead. Even after its description in 1894 little notice was taken of the species, and even numbers are hard to gauge from early accounts of the species. Based on the accounts written by Web ...

In urban areas the condition was comparatively better and the percentage of people living below the poverty line was the least in the whole of Madagascar. The country's largest harbour–Toamasina Harbour was located in the province. Vanilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meller's Duck
Meller's duck (''Anas melleri'') is a species of the dabbling duck genus ''Anas''. It is endemic to eastern Madagascar. Although a population was established on Mauritius in the mid-18th century, this is on the verge of extinction due to habitat loss and competition by feral domestic ducks. The species name of this species is after the botanist Charles James Meller, and its generic name is from the Latin for "duck". Description The Meller's duck resembles a large female mallard. At , it averages slightly larger than a mallard and is at the top size for the genus ''Anas''. . arkive.org However, as opposed to most mallard relatives, they lack a . The |
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 ...

Ramsar List Of Wetlands Of International Importance
This is the list of Wetlands of International Importance as defined by the Ramsar Convention for the conservation and sustainable use of wetlands, recognizing the fundamental ecological functions of wetlands and their economic, cultural, scientific, and recreational value. The convention establishes that "wetlands should be selected for the list on account of their international significance in terms of ecology, botany, zoology, limnology or hydrology." Over the years, the Conference of the Contracting Parties has adopted more specific criteria interpreting the convention text. The Ramsar List organizes the Ramsar sites according to the contracting party that designated each to the list. Contracting parties are grouped into six "regions": Africa, Asia, Europe, Latin American and the Caribbean, North America, and Oceania. , 170 states have acceded to the convention and designated 2,471 sites to the list, covering ; two other states have acceded to the convention but have yet to des ...

Oreochromis Macrochir
''Oreochromis macrochir'' (longfin tilapia, greenhead tilapia, or greenhead bream) is a species of cichlid native to the Zambezi Basin, Lake Mweru, and Lake Bangweulu Bangweulu — 'where the water sky meets the sky' — is one of the world's great wetland systems, comprising Lake Bangweulu, the Bangweulu Swamps and the Bangweulu Flats or floodplain.Camerapix: ''Spectrum Guide to Zambia.'' Camerapix Internation .... It has been used extensively for stocking ponds and dams in other parts of southern Africa, but is little-used elsewhere. In Lake Mweru, it is economically the most important fish. The fish was introduced into Lake Alaotra in Madagascar in 1954, and proliferated quickly. By 1957, it provided 46% of the catch, perhaps because it was moving into an empty ecological niche as a phytophagous species. This species reaches a maximum length of .

Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
