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] |

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, al ...

Durrell Wildlife Conservation Trust
Durrell Wildlife Conservation Trust is a conservation organization with a mission to save species from extinction. Gerald Durrell founded the Jersey Wildlife Preservation Trust as a charitable institution in 1963 with the dodo as its symbol. The trust was renamed Durrell Wildlife Conservation Trust in its founder's honor on 26 March 1999. Its patron is Princess Anne, the Princess Royal. Its headquarters are at Les Augrès Manor on the isle of Jersey in the English Channel. The grounds of Les Augrès Manor form the Durrell Wildlife Park, which was originally established by Gerald Durrell in 1959 as a sanctuary and breeding center for endangered species. The zoological park was known as the ''Jersey Zoo'' at that time. As of 2016, the zoo was home to more than one hundred species of reptiles, birds and mammals, many of which are designated as endangered in the wild. Despite strong resistance to his ideas from much of the zoological community, in 1959 Gerald Durrell succeeded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Pochard, Captive Breeding Program, Madagascar 3
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] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Agriculture In Madagascar
Agriculture employs the majority of Madagascar's population. Mainly involving smallholders, agriculture has seen different levels of state organisation, shifting from state control to a liberalized sector. Rice is the main produce and main export crop of Madagascar. It is mainly planted in a terraced paddy system in the central highlands. Other major subsistence crops include cassava, corn, and sweet potato, while coffee, cloves, vanilla and other cash crops are exported. Among livestock, zebu account for most of the cattle, while pigs, sheep and poultry are also raised. Fishing is popular, and aquaculture has grown in importance. Madagascar has seen high rates of deforestation, and the illegal extraction of highly valued timber species such as mahogany, ebony, and rosewood threatens native stands. The traditional slash-and-burn agriculture (''tavy'') together with population growth put increasing pressure on the native and very diverse flora of Madagascar. Production Madag ...

Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyperaceae
The Cyperaceae () are a family of graminoid (grass-like), monocotyledonous flowering plants known as wikt:sedge, sedges. The family (biology), family is large; botanists have species description, described some 5,500 known species in about 90 genus, generathe largest being the "true wikt:sedge, sedges" (genus ''Carex''), with over 2,000 species. Distribution Cyperaceae species are widely distributed with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges grow in almost all environments, many thrive in wetlands or in poor soils. Community (ecology), Ecological communities dominated by sedges are known as s or as sedge meadows. Classification Some species superficially resemble the closely related Juncaceae , rushes and the more distantly related grasses.
