Magnificent Bird-of-paradise
The magnificent bird-of-paradise (''Diphyllodes magnificus'') is a species of bird-of-paradise. The magnificent bird-of-paradise is evaluated as Least Concern on the IUCN Red List of Threatened Species. They are listed in Appendix II of CITES. Etymology The generic name ''Cicinnurus'' means "curled tail" and its specific name ''magnificus'' means magnificent or splendid. The species was formerly listed in the genus ''Diphyllodes'', which means "Double leaf-like", referring to its "leaf-like" tail. Taxonomy The magnificent bird-of-paradise is included in the same genus as the King and Wilson's Birds-of-paradise, though it is more closely related to the latter. The genus ''Cicinnurus'' forms a clade with the genera '' Paradisaea'' and '' Paradisornis'', and the other closest genus is '' Astrapia,'' though it is not included in the clade. Three subspecies are recognised: * ''D. m. magnificus'' ( Pennant, 1781) – Salawati (Raja Ampat Islands, northwest of New Guinea) and south ...

Thomas Pennant
Thomas Pennant (16 December 1798) was a Welsh natural history, naturalist, traveller, writer and antiquarian. He was born and lived his whole life at his family estate, Downing Hall, near Whitford, Flintshire, in Wales. As a naturalist he had a great curiosity, observing the geography, geology, plants, animals, birds, reptiles, amphibians, and fish around him and recording what he saw and heard about. He wrote acclaimed books including ''British Zoology'', the ''History of Quadrupeds'', ''Arctic Zoology'' and ''Indian Zoology'' although he never travelled further afield than continental Europe. He knew and maintained correspondence with many of the scientific figures of his day. His books influenced the writings of Samuel Johnson. As an antiquarian, he amassed a considerable collection of art and other works, largely selected for their scientific interest. Many of these works are now housed at the National Library of Wales. As a traveller he visited Scotland and many other par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Adolf Bernhard Meyer
Adolf Bernhard Meyer (11 October 1840, Hamburg – 22 August 1911, Dresden) was a German anthropologist, ornithologist, entomologist, and herpetologist. He served for nearly thirty years as director of the Königlich Zoologisches und Anthropologisch-Ethnographisches Museum (now the natural history museum or Museum für Tierkunde Dresden) in Dresden. He worked on comparative anatomy and appreciated the ideas of evolution, and influenced many German scientists by translating into German the 1858 papers by Darwin and Wallace which first proposed evolution by natural selection. Influenced by the writings of Wallace with whom he interacted, he travelled to Southeast Asia, and collected specimens and recorded his observations from the region. Biography Meyer was born in a wealthy Jewish family in Hamburg as Aron Baruch Meyer, and was educated at the universities of Göttingen, Vienna, Zürich and Berlin. He became director of the Anthropological and Ethnographic Museum in Dresden in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sympatry
In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and ...

Female
An organism's sex is female ( symbol: ♀) if it produces the ovum (egg cell), the type of gamete (sex cell) that fuses with the male gamete (sperm cell) during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes (unlike isogamy where they are the same size). The exact mechanism of female gamete evolution remains unknown. In species that have males and females, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Characteristics of organisms with a female sex vary between different species, having different female reproductive systems, with some species showing characteristics secondary to the reproductive system, as with mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender in the social sense of gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sickle
A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting or reaping grain crops, or cutting Succulent plant, succulent forage chiefly for feeding livestock. Falx was a synonym, but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge. Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved, initially of iron and later steel. This great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using slightly different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is even found in modern grain-harvesting machines and in some kitchen knives.

Turquoise (color)
Turquoise ( ) is a cyan color, based on the turquoise, mineral of the same name. The word ''turquoise'' dates to the 17th century and is derived from the French language, French , meaning 'Turkish', because the mineral was first brought to Europe through Turkey from mines in the historical Greater Khorasan, Khorasan province of Iran (Persia) and Afghanistan today. The first recorded use of ''turquoise'' as a color name in English language, English was in 1573. The Web colors#X11 color names, X11 color named turquoise is displayed on the right. Turquoise gemstones Turquoise is an opaque, blue-to-green mineral that is a hydrate, hydrous phosphate of copper and aluminium, with the chemical formula copper, Cualuminium, Al6(phosphorus, Poxygen, O4)4(Ohydrogen, H)8·4water, H2O. It is rare and valuable in finer grades and has been prized as a gemstone, gem and ornamental stone for thousands of years owing to its unique hue.

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. The first recorded use of ''lime green'' as a color name in English was in 1890. Lime (color hex code #C0FF00) is a pure spectral color at approximately 564 nanometers on the visible spectrum when plotted on the CIE chromaticity diagram. Usage During the 2000s, lime green was a very popular aesthetic, particularly with products, throughout the entirety ...

Iridescence
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and acted as a messenger of th ...

Scalloped
Scallop () is a common name that encompasses various species of marine bivalve molluscs in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cape
A cape is a clothing accessory or a sleeveless outer garment of any length that hangs loosely and connects either at the neck or shoulders. They usually cover the back, shoulders, and arms. They come in a variety of styles and have been used throughout history for many different reasons. Semantic distinction In fashion, the word "cape" usually refers to a shorter garment and "cloak" to a full-length version of the different types of garment, though the two terms are sometimes used synonymously for full-length coverings. A shoulder cape is thus sometimes called a "capelet". The fashion cape does not cover the front to any appreciable degree. In raingear, a cape is usually a long and roomy protective garment worn to keep one dry in the rain. History The first known usage of capes is unknown, but some early references we know of are from Ancient Roman military uniforms. Later on, capes were common in medieval Europe, especially when combined with a hood in the chaperon. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sulfur
Sulfur ( American spelling and the preferred IUPAC name) or sulphur ( Commonwealth spelling) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere Th ...

Male
Male (Planet symbols, symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or Egg cell, ovum, in the process of fertilisation. A male organism cannot sexual reproduction, reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and Asexual reproduction, asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. In humans, the word ''male'' can also be used to refer to gender, in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineage (evolution), lineages, an example of convergent evolution. The repeated pattern is sexual reproduction in isogamy, isogamous species with two or more mating types with gametes of identic ...
