Gilles Deslisle
The Gilles are the oldest and principal participants in the Carnival of Binche in Belgium. They go out on Shrove Tuesday from 4 am until late hours and dance to traditional songs. Other cities, such as La Louvière and Nivelles, have a tradition of Gilles at carnival, but the Carnival of Binche is by far the most famous. In 2003, the Carnival of Binche was proclaimed one of the Masterpieces of the Oral and Intangible Heritage of Humanity The Proclamation of Masterpieces of the Oral and Intangible Heritage of Humanity was made by the Director-General of UNESCO starting in 2001 to raise awareness of intangible cultural heritage and encourage local communities to protect them and t ... by UNESCO.Logan p.223 Costume Around 1000 Gilles, all male, some as young as three years old, wear the traditional costume of the Gille on Shrove Tuesday.

Aristolochic Acid
Aristolochic acids () are a family of carcinogenic, mutagenic, and nephrotoxic phytochemicals commonly found in the flowering plant family Aristolochiaceae (birthworts). Aristolochic acid (AA) I is the most abundant one. The family Aristolochiaceae includes the genera ''Aristolochia'' and '' Asarum'' (wild ginger), which are commonly used in Chinese herbal medicine. Although these compounds are widely associated with kidney problems, liver and urothelial cancers, the use of AA-containing plants for medicinal purposes has a long history. The FDA has issued warnings regarding consumption of AA-containing supplements. History Early medical uses Birthwort plants, and the aristolochic acids they contain, were quite common in ancient Greek and Roman medical texts, well-established as an herb there by the fifth century BC. Birthworts appeared in Ayurvedic texts by 400 AD, and in Chinese texts later in the fifth century. In these ancient times, it was used to treat kidney and urinary pro ...

Fauna Of New Guinea
The fauna of New Guinea comprises a large number of species of mammals, reptiles, birds, fish, invertebrates and amphibians. As the world's largest and highest tropical island, New Guinea occupies less than 0.5% of world's land surface, yet supports a high percentage of global biodiversity. Approximately 4,624 vertebrate species inhabit the island of New Guinea and its surrounding waters, which constitutes about 8% of the recognized world vertebrates. This ranges from an estimated 4% of the world's lizards and mammals, to about 10% of the world's fish species. The numbers of global and New Guinea invertebrate species are poorly known, and thus an accurate comparison is difficult. Butterflies are the best known invertebrate group, and are represented in New Guinea by about 735 species, which is about 4.2% of the world total of 17,500 species. Origin History New Guinea is a large island located north of Australia, and south-east of Asia. It is part of the Australian Plate, known as ...

Conservation In Papua New Guinea
Papua New Guinea together with the West Papua region of Indonesia ( New Guinea) make up a major tropical wilderness area that still contains 5% of the original and untouched tropical high-biodiversity terrestrial ecosystems. PNG in itself contains over 5% of the world's biodiversity in less than 1% of the world's total land area. The flora of New Guinea is unique because it has two sources of origin; the Gondwana flora from the south and flora with Asian origin from the west. As a result, New Guinea shares major family and genera with Australia and the East Asia, but is rich in local endemic species. The endemicity is a result of mountainous isolation, topographic and soil habitat heterogeneity, high forest disturbance rates and abundant aseasonal rainfall year round. PNG boasts some 15–21,000 higher plants, 3,000 species of orchids, 800 species of coral, 600 species of fish, 250 species of mammals and 760 species of birds and 8 species of tree-kangaroos out of which 84 gen ...

1951 Eruption Of Mount Lamington
In early January 1951, a series of minor explosions and earthquakes rocked Mount Lamington, a volcano in Oro Province, Territory of Papua and New Guinea. Prior to the eruption, Mount Lamington was not recognized as a volcano due to the absence of historically-recorded eruptions and dense vegetation cover. From January 15, volcanic activity intensified, and tall eruption plumes were generated. The largest eruption occurred on the morning of January 21 when a thick black plume of ash rose into the atmosphere. The eruption collapsed a lava dome and produced a lethal pyroclastic flow that killed 2,942–3,466 people. In the years after the eruption, new lava domes formed and collapsed in succession. Activity persisted until July 1956. The eruption is the deadliest natural disaster in Australian history, as the region was under the rule of the Government of Australia. Tectonic setting Volcanism in Papua New Guinea is due to the ongoing subduction of oceanic crust beneath the island du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Palm
''Elaeis'' () is a genus of palms containing two species, called oil palms. They are used in commercial agriculture in the production of palm oil. The African oil palm ''Elaeis guineensis'' (the species name ''guineensis'' referring to its country of origin) is the principal source of palm oil. It is native to west and southwest Africa, occurring between Angola and Gambia. The American oil palm ''Elaeis oleifera'' () is native to tropical Central and South America, and is used locally for oil production. Description Mature palms are single-stemmed, and can grow well over tall. The leaves are pinnate, and reach between long. The flowers are produced in dense clusters; each individual flower is small, with three sepals and three petals. The palm fruit is reddish, about the size of a large plum, and grows in large bunches. Each fruit is made up of an oily, fleshy outer layer (the pericarp), with a single seed (the palm kernel), also rich in oil. Species The two species, '' ...

Popondetta
Popondetta (sometimes spelled Popondota) is the capital of Oro (Northern) Province in Papua New Guinea. Popondetta is a city. In 1951 the city became the focus of relief efforts after nearby Mount Lamington erupted and killed 4,000 people. Popondetta is near to Buna on the Northern Papua coast and is not far from the beginning of the Kokoda Trail, made famous during World War II. This area of New Guinea is home to the endangered Queen Alexandra's birdwing, the world's largest butterfly. Climate Popondetta has a tropical rainforest climate (Köppen ''Af'') with heavy rainfall year-round.

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). P ...

Hibiscus
''Hibiscus'' is a genus of flowering plants in the mallow family, Malvaceae. The genus is quite large, comprising several hundred species that are native to warm temperate, subtropical and tropical regions throughout the world. Member species are renowned for their large, showy flowers and those species are commonly known simply as "hibiscus", or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus. The genus includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The generic name is derived from the Greek name ἰβίσκος (''ibískos'') which Pedanius Dioscorides gave to ''Althaea officinalis'' ( 40–90 AD). Several species are widely cultivated as ornamental plants, notably ''Hibiscus syriacus'' and ''Hibiscus rosa-sinensis''. A tea made from hibiscus flowers is known by many names around the world and is served both hot and cold. The beverage is known for its red colour, t ...
