All living organisms emit, detect, and respond to chemical stimuli, thus creating an almost
limitless number of interactions by means of chemical signals. Technological and intellectual …

Covering: 2017–2019 Guanidine natural products isolated from microorganisms, marine
invertebrates and terrestrial plants, amphibians and spiders, represented by non-ribosomal …

The updated third edition of the only textbook on colour The revised third edition of Colour
and the Optical Properties of Materials focuses on the ways that colour is produced, both in …

Transparency in animals is a complex form of camouflage involving mechanisms that reduce
light scattering and absorption throughout the organism. In vertebrates, attaining …

The initial evolution of warning signals in unprofitable prey, termed aposematism, is often
seen as a paradox because any new conspicuous mutant would be easier to detect than its …

Fluorescence of visible wavelengths under ultraviolet (UV) light has been previously
detected in a wide range of birds, reptiles, and amphibians and a few marsupial mammals …

Biofluorescence is the absorption of electromagnetic radiation (light) at one wavelength
followed by its reemission at a lower energy and longer wavelength by a living organism …

Biofluorescence is widespread in the natural world, but only recently discovered in terrestrial
vertebrates. Here, we report on the discovery of iridophore-based, neon-green flourescence …

Fluorescence is widespread in marine organisms but uncommon in terrestrial tetrapods. We
here show that many chameleon species have bony tubercles protruding from the skull that …

Biofluorescence has been detected in several nocturnal-crepuscular organisms from
invertebrates to birds and mammals. Biofluorescence in mammals has been detected across …
