In some spiders, ultraviolet cues are important for predator-prey interactions, intraspecific communication, and camouflage-matching with fluorescent flowers. Differing ecological contexts could favor inhibition or enhancement of fluorescence expression, depending upon whether fluorescence helps spiders be cryptic or makes them more conspicuous to predators. Therefore, natural selection could be acting on expression of fluorescence across spider species. [56] Physical principles [ edit ] Mechanism [ edit ] A ruby ball lens atop a green laser-pointer. The green beam converges into a cone within the crystal and is focused to a point on top. The green light is absorbed and spontaneously remitted as red light. Not all of the light is absorbed, and a small portion of the 520 nm laser-light transmits through the top, unaltered by the ruby's red color. Currently, relatively little is known about the functional significance of fluorescence and fluorescent proteins. [30] However, it is suspected that fluorescence may serve important functions in signaling and communication, mating, lures, camouflage, UV protection and antioxidation, photoacclimation, dinoflagellate regulation, and in coral health.

Fluorescence also occurs frequently in nature in some minerals and in many biological forms across all kingdoms of life. The latter may be referred to as biofluorescence, indicating that the fluorophore is part of or is extracted from a living organism (rather than an inorganic dye or stain). But since fluorescence is due to a specific chemical, which can also be synthesized artificially in most cases, it is sufficient to describe the substance itself as fluorescent.Spiders fluoresce under UV light and possess a huge diversity of fluorophores. Andrews, Reed, & Masta noted that spiders are the only known group in which fluorescence is "taxonomically widespread, variably expressed, evolutionarily labile, and probably under selection and potentially of ecological importance for intraspecific and interspecific signaling". [56] They showed that fluorescence evolved multiple times across spider taxa, with novel fluorophores evolving during spider diversification. Fox, A. (2 April 2019).

The color defined as blue in the RGB color model, X11 blue, is the brightest possible blue that can be reproduced on a computer screen, and is the color named blue in X11. It is one of the three primary colors used in the RGB color space, along with red and green. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a computer or television set.

One of several important cell sorting techniques used in the separation of different cell lines (especially those isolated from animal tissues). Fingerprints can be visualized with fluorescent compounds such as ninhydrin or DFO ( 1,8-Diazafluoren-9-one). Blood and other substances are sometimes detected by fluorescent reagents, like fluorescein. Fibers, and other materials that may be encountered in forensics or with a relationship to various collectibles, are sometimes fluorescent. Shkolnikov, V; Santiago, J. G. (2013).

The polka-dot tree frog ( Hypsiboas punctatus), widely found in South America, was unintentionally discovered to be the first fluorescent amphibian in 2017. The fluorescence was traced to a new compound found in the lymph and skin glands. [48] The main fluorescent compound is Hyloin-L1 and it gives a blue-green glow when exposed to violet or ultraviolet light. The scientists behind the discovery suggested that the fluorescence can be used for communication. They speculated that fluorescence possibly is relatively widespread among frogs. [49] Only a few months later, fluorescence was discovered in the closely related Hypsiboas atlanticus. Because it is linked to secretions from skin glands, they can also leave fluorescent markings on surfaces where they have been. [50] The incidence of fluorescence across the tree of life is widespread, and has been studied most extensively in cnidarians and fish. The phenomenon appears to have evolved multiple times in multiple taxa such as in the anguilliformes (eels), gobioidei (gobies and cardinalfishes), and tetradontiformes (triggerfishes), along with the other taxa discussed later in the article. Fluorescence is highly genotypically and phenotypically variable even within ecosystems, in regards to the wavelengths emitted, the patterns displayed, and the intensity of the fluorescence. Generally, the species relying upon camouflage exhibit the greatest diversity in fluorescence, likely because camouflage may be one of the uses of fluorescence. [29] Fluorescence has multiple origins in the tree of life. This diagram displays the origins within actinopterygians (ray finned fish).The color blue is the top favorite color around the world. It’s the popular kid at parties, the superhero that everyone trusts. Choosing a Neon Blue color scheme infuses this amazing hue with some electric flair. The Neon Blue color code is perfect for high-energy, modern designs that love to be the center of attention. Add some fluorescent yellow to make a warmer fluorescent green.

Many plants are fluorescent due to the presence of chlorophyll, which is probably the most widely-distributed fluorescent molecule, producing red emission under a range of excitation wavelengths. [59] This attribute of chlorophyll is commonly used by ecologists to measure photosynthetic efficiency. [60] Firefly Squid - Deep Sea Creatures on Sea and Sky". www.seasky.org.

Improvements since then have largely been better phosphors, longer life, and more consistent internal discharge, and easier-to-use shapes (such as compact fluorescent lamps). Some high-intensity discharge (HID) lamps couple their even-greater electrical efficiency with phosphor enhancement for better color rendition.
