Parotia Lawesii
Lawes's parotia (''Parotia lawesii''), is a medium-sized (up to 27 cm long) passerine of the bird-of-paradise family, Paradisaeidae. It is distributed and endemic to mountain forests of southeast and eastern Papua New Guinea. Occasionally, the eastern parotia is considered a subspecies of ''P. lawesii''. The species is similar to the western parotia (''Parotia sefilata''). Like most birds of paradise, male Lawes's parotia are polygamous. The few eggs that have been studied were about 33 x 24 mm in size, but these were possibly small specimens. It eats mainly fruit, seeds and arthropods. The bird's home was discovered by Carl Hunstein on a mountain near Port Moresby in 1884. Its name honors the New Guinea pioneer missionary Reverend William George Lawes. Widespread and common throughout its range, Lawes's parotia is evaluated as Least Concern on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES.

Edward Pierson Ramsay
Edward Pierson Ramsay FRSEFLS LLD (3 December 1842 – 16 December 1916) was an Australian zoologist who specialised in ornithology. Early life Ramsay was born in Dobroyd Estate, Long Cove, Sydney, and educated at St Mark's Collegiate School, The King's School, Sydney, The King's School, Parramatta. He studied medicine from 1863 to 1865 at the University of Sydney but did not graduate. Career Although he never had had any formal scientific training in zoology, Ramsay had a keen interest in natural history and published many papers. In 1863 he was treasurer of the Entomological Society of New South Wales, he contributed a paper on the "Oology of Australia" to the Philosophical Society in July 1865, and when this society was merged into the Royal Society of New South Wales, he was made a life member in recognition of the work he had done for the Philosophical Society. In 1868 Ramsay joined with his brothers in a sugar-growing plantation in Queensland which, however, was not succes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missionary
A missionary is a member of a Religious denomination, religious group which is sent into an area in order to promote its faith or provide services to people, such as education, literacy, social justice, health care, and economic development.Thomas Hale 'On Being a Missionary' 2003, William Carey Library Pub, . In the Bible translations into Latin, Latin translation of the Bible, Jesus, Jesus Christ says the word when he sends the disciples into areas and commands them to preach the gospel in his name. The term is most commonly used in reference to Christian missions, but it can also be used in reference to any creed or ideology. The word ''mission'' originated in 1598 when Jesuits, the members of the Society of Jesus sent members abroad, derived from the Latin (nominative case, nom. ), meaning 'act of sending' or , meaning 'to send'. By religion Buddhist missions The first Buddhist missionaries were called "Dharma Bhanaks", and some see a missionary charge in the symbolis ...

Parotia
The parotias are a genus, ''Parotia'', of passerine birds in the bird-of-paradise family Paradisaeidae. They are endemic to New Guinea. They are also known as six-plumed birds of paradise, due to their six head quills. These birds were featured prominently in the BBC series ''Planet Earth''. The males of the genus are characterized by an ornamental plumage consisting of six wired head plumes with black oval-shaped tips, a neck collar of black, decomposed feathers which can be spread into a skirt-like shape, and bright or iridescent head and throat markings. During courtship, they perform ballerina-like dances and spread out their "skirt" on a patch of forest floor they have meticulously cleaned of dead leaves and other debris. The "ballerina dances" usually consist of the male hopping from foot and bobbing their heads from side to side. The males are polygamous and do not take part in raising the young. Clutch size is somewhat uncertain; it is usually one to three eggs. Taxono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proceedings Of The Royal Society
''Proceedings of the Royal Society'' is the main research journal of the Royal Society. The journal began in 1831 and was split into two series in 1905: * Series A: for papers in physical sciences and mathematics. * Series B: for papers in life sciences. Many landmark scientific discoveries are published in the Proceedings, making it one of the most historically significant science journals. The journal contains several articles written by the most celebrated names in science, such as Paul Dirac, Werner Heisenberg, Ernest Rutherford, Erwin Schrödinger, William Lawrence Bragg, Lord Kelvin, J.J. Thomson, James Clerk Maxwell, Dorothy Hodgkin and Stephen Hawking. In 2004, the Royal Society began ''The Journal of the Royal Society Interface'' for papers at the interface of physical sciences and life sciences.

Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skirt
A skirt is the lower part of a dress or a separate outer garment that covers a person from the waist downwards. At its simplest, a skirt can be a draped garment made out of a single piece of fabric (such as pareos). However, most skirts are fitted to the body at the waist or hips and fuller below, with the fullness introduced by means of darts, gores, pleats, or panels. Modern skirts are usually made of light to mid-weight fabrics, such as denim, jersey, worsted, or poplin. Skirts of thin or clingy fabrics are often worn with slips to make the material of the skirt drape better and for modesty. In modern times, skirts are very commonly worn by women and girls. Some exceptions include the izaar, worn by many Muslim cultures, and the kilt, a traditional men's garment in Scotland, Ireland, and sometimes England. Fashion designers such as Jean Paul Gaultier, Vivienne Westwood, Kenzo and Marc Jacobs have also shown men's skirts. Transgressing social codes, Gaultier frequently intr ...

Lime (color)
Lime is a color that is a shade of yellow-green, so named because it is a representation of the color of the citrus fruit called limes. It is the color that is in between the web color chartreuse and yellow on the color wheel.Maerz and Paul ''A Dictionary of Color'' New York: 1930 McGraw-Hill; The index refers to Plate 20 Color Sample J1 as ''Lime Green''; this color is shown on Plate 20 as being halfway between ''yellow-green'' (the old name for the color that is now called chartreuse green) and ''yellow'' on the color wheel. Alternate names for this color included yellow-green, lemon-lime, lime green, or bitter lime. Lime (traditional lime green) The first recorded use of ''lime green'' as a color name in English was in 1890. Lime (color hex code #BFFF00) is a pure spectral color at approximately 564 nanometers on the visible spectrum when plotted on the CIE chromaticity diagram.

Sexual Selection
Sexual selection is a mode of natural selection in which members of one biological sex mate choice, choose mates of the other sex to mating, mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual selection). These two forms of selection mean that some individuals have greater reproductive success than others within a population, for example because they are more Animal sexual behaviour, attractive or prefer more attractive partners to produce offspring. Successful males benefit from frequent mating and monopolizing access to one or more fertile females. Females can maximise the return on the energy they invest in reproduction by selecting and mating with the best males. The concept was first articulated by Charles Darwin who wrote of a "second agency" other than natural selection, in which competition between mate candidates could lead to speciation. The theory was given a mathematical basis by Ronald F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural Coloration
Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination with pigments. For example, peacock tail feathers are pigmented brown, but their microscopic structure makes them also reflect blue, turquoise, and green light, and they are often iridescent. Structural coloration was first observed by English scientists Robert Hooke and Isaac Newton, and its principle – wave interference – explained by Thomas Young a century later. Young described iridescence as the result of interference between reflections from two or more surfaces of thin films, combined with refraction as light enters and leaves such films. The geometry then determines that at certain angles, the light reflected from both surfaces interferes constructively, while at other angles, the light interferes destructively. Different colours ...

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...
