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 We ...

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized 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 colouration, 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, along or ...

The Peregrine Fund
The Peregrine Fund (named after the bird of prey of the same name the peregrine falcon) is a non-profit organization founded in 1970 that conserves threatened and endangered birds of prey worldwide. The successful recovery of the peregrine falcon in the United States, which was removed from the U.S. Endangered Species List in 1999, enabled the organization to expand its mission to include other endangered raptors around the world. The Peregrine Fund is headquartered at its World Center for Birds of Prey in Boise, Idaho, on a campus with breeding and research facilities, an administrative office, interpretive center, research library, and archives. Mission The Peregrine Fund's mission is to restore rare species through captive breeding and release, improve capacity for local conservation, conduct scientific research and environmental education, and conserve habitat. It currently is involved in recovery of the California condor and Aplomado Falcon, and research on American Kes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildfowl & Wetlands Trust
The Wildfowl & Wetlands Trust (WWT) is an international wildfowl and wetland conservation charity in the United Kingdom. Its patron is Charles III, and its president is Kate Humble. History The WWT was founded in 1946 by the ornithologist and artist Sir Peter Scott as the Severn Wildfowl Trust. The first site at Slimbridge was a centre for research and conservation. In a move unusual at the time, he opened the site to the public so that everyone could enjoy access to nature. This modest beginning developed in time into the formation of the Wildfowl & Wetlands Trust, the only United Kingdom charity to promote the protection of wetland birds and their habitats, both in Britain and internationally. Although starting out at Slimbridge, the Wildfowl & Wetlands Trust now owns or manages eight other reserves in Britain, and advocates for wetlands and conservation issues world-wide. WWT Consulting is an offshoot of the Wildlife & Wetland Trust and is based at Slimbridge. It provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 succeede ... [...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 the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, 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 webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter ('' Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus '' Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks.
