Lake Alaotra
Lake Alaotra (, ; ) is the largest lake in Madagascar, located in Alaotra-Mangoro, 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 Ramsar List of Wetlands of International Importance, wetland of international importance under the international Ramsar Convention on February 2, 2003. The Oreochromis macrochir, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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.

Lakes Of Madagascar
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...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 a recently extinct grebe that was endemic to Lake Alaotra and its surrounding lakes in Madagascar. Experts say that the grebe became extinct after carnivorous fish were introduced into its native habitat. The last sighting of the Alaotra grebe was in 1983 or 1985 and it was officially declared extinct in 2010. Description The grebe was about long. Its ability to fly long distances was restricted because of its small wings. It exhibited no marked sexual dimorphism, although males were slightly larger than females. Diet 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. Breeding 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 court ...

Madagascar Pochard
The Madagascar pochard or Madagascan pochard (''Aythya innotata''; ) 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, The population is small, fluctuating around 25 individuals, and mainly utilises two small volcanic lakes in the far north of Madagascar. ''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 ... [...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 |
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, sea eagles, fish eagles, fish owls, and fishing owls, hunt aquatic prey but do not stay in water for long and live predominantly over dry land, and are not considered water birds.
