Supernormal Stimulus
A supernormal stimulus or superstimulus is an exaggerated version of a stimulus to which there is an existing response tendency, or any stimulus that elicits a response more strongly than the stimulus for which it evolved. For example, it is possible to create artificial bird eggs which certain birds will prefer over their own eggs, particularly evident in brood parasitism. Some speculate humans can be similarly exploited by junk food. Organisms tend to show a preference for the stimulus properties (e.g. size, colour, etc.) that have evolved in nature, but when offered an artificial exaggerated stimulus, animals will show behaviour in favour of the artificial stimulus over the naturally occurring stimulus. A variety of organisms display or are susceptible to supernormal stimuli, including insects, birds, and humans. Supernormal stimuli are present in areas of biology and psychology, but are also studied within other fields like sociology and art. British academic Nigel Spive ...

Venus Von Willendorf 01
Venus is the second planet from the Sun. It is often called Earth's "twin" or "sister" planet for having almost the same List of Solar System objects by size, size and mass, and the closest orbit to Earth's. While both are rocky planets, Venus has an Atmosphere of Venus, atmosphere much thicker and denser than Earth and any other rocky body in the Solar System. Its atmosphere is composed of mostly carbon dioxide (), with a global sulfuric acid cloud cover and no List of largest lakes and seas in the Solar System, liquid water. At the mean surface level the atmosphere reaches a temperature of and a atmospheric pressure, pressure 92 times greater than Earth's at sea level, turning the lowest layer of the atmosphere into a supercritical fluid. Venus is the List of brightest natural objects in the sky, third brightest object in Earth's sky, after the Moon and the Sun, and, like Mercury (planet), Mercury, appears always relatively close to the Sun, either as a "morning star" or ...

Parental Investment
Parental investment, in evolutionary biology and evolutionary psychology, is any parental expenditure (e.g. time, energy, resources) that benefits offspring.Clutton-Brock, T.H. 1991. ''The Evolution of Parental Care''. Princeton, NJ: Princeton U. Press. pg. 9Trivers, R.L. (1972). Parental investment and sexual selection. In B. Campbell (Ed.), ''Sexual selection and the descent of man'', 1871-1971 (pp. 136–179). Chicago, IL: Aldine. . Parental investment may be performed by both males and females (called ''biparental care''), females alone (''exclusive maternal care'') or males alone (''exclusive paternal care''). Care can be provided at any stage of the offspring's life, from pre-natal (e.g. egg guarding and Egg incubation, incubation in birds, and placental nourishment in mammals) to post-natal (e.g. food provisioning and protection of offspring). Parental investment theory, a term coined by Robert Trivers in 1972, predicts that the sex that invests more in its offsprin ...

Eurasian Reed Warbler
The common reed warbler (''Acrocephalus scirpaceus'') is an Old World warbler in the genus '' Acrocephalus''. It breeds across Europe into the temperate western Palaearctic where it is migratory, wintering in sub-Saharan Africa. It is also a resident species over large parts of Africa. Taxonomy The common reed warbler was formally described in 1804 by the French naturalist Johann Hermann under the binomial name ''Turdus scirpaceus''. The type locality is Alsace. The common reed warbler is now one of around 40 species placed in the genus '' Acrocephalus'' that was introduced by Johann Andreas Naumann and his son Johann Friedrich Naumann in 1811. The genus name ''Acrocephalus'' is from Ancient Greek ''akros'', "highest", and ''kephale'', "head". It is possible that the Naumanns thought ''akros'' meant "sharp-pointed". The specific ''scirpaceus'' is from Latin and means "reed". Ten subspecies are recognised: * ''A. s. scirpaceus'' (Hermann, 1804) – breeds in Europe to west ...

Cuckoo
Cuckoos are birds in the Cuculidae ( ) family, the sole taxon in the order Cuculiformes ( ). The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals, and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae, respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species, which are divided into 33 genera. The cuckoos are generally medium-sized, slender birds. Most species live in trees, though a sizeable minority are ground-dwelling. The family has a cosmopolitan distribution; the majority of species are tropical. Some species are migratory. The cuckoos feed on insects, insect larvae, and a variety of other animals, as well as fruit. Some species are brood parasites, laying their eggs in the nests of other species and giving rise to the terms " cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silver-washed Fritillary
The silver-washed fritillary (''Argynnis paphia'') is a common and variable butterfly found over much of the Palearctic realm – Algeria, Europe and across the Palearctic to Japan. Description The silver-washed fritillary butterfly is deep orange with black spots on the upperside of its wings. It has a wingspan of 54–70 mm, with the male's being smaller and paler than the female's. The underside is green (verdigris) with a metallic gloss and broad silver bands which are partly curved, hence the name silver-washed. In the male the forewings are rather pointed whereas in the female they are more rounded. On females of the minority ''valesina'' form, recurrent in most European populations, the ground color is not fawn but grey with greenish reflections. The caterpillar is black brown with two yellow lines along its back and long reddish-brown spines. The male possesses scent scales on the upperside of the forewing that run along veins one to four as three distinct scent-str ...

Cucumber Mosaic Virus
Cucumber mosaic virus (CMV) is a plant pathogenic virus in the family ''Bromoviridae''. This virus has a worldwide distribution and a very wide host range, having the reputation of the widest host range of any known plant virus. It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, ''Cuscuta sp.'' (dodder). Hosts and symptoms This virus was first characterized in cucumbers (''Cucumis sativus'') showing mosaic symptoms in 1934, hence the name ''Cucumber mosaic''. Since then, it has been found to infect a great variety of other plants. These include other vegetables such as squash, melons, peppers, eggplants, tomatoes, beans, carrots, celery, lettuce, spinach, beets, many ornamentals and bedding plants, such as '' Narcissus'', and various weeds. Its presence has been confirmed on every continent of the world, including Antarctica. Symptoms seen with this virus in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ig Nobel Prize
The Ig Nobel Prize () is a satirical prize awarded annually since 1991 to promote public engagement with scientific research. Its aim is to "honor achievements that first make people laugh, and then make them think." The name of the award is a pun on the Nobel Prize, which it parodies, and on the word "ignoble". Organized by the scientific humor magazine '' Annals of Improbable Research'' (AIR), the Ig Nobel Prizes are presented by Nobel laureates in a ceremony at the Massachusetts Institute of Technology. The winners also deliver public lectures. The Ig Nobel Prize monetary award is given in a solitary banknote for the amount of 10 trillion Zimbabwean dollars ($0.40 USD, but the banknote is worth more as a collector's item). History The Ig Nobels were created in 1991 by Marc Abrahams, then editor-in-chief of the '' Journal of Irreproducible Results'' and later co-founder of the '' Annals of Improbable Research'', who has been the master of ceremonies at all awards ceremon ...
