The word melanin refers to dark natural pigments produced by the oxidative degradation of tyrosine, catalyzed by tyrosinase, and polymerized into insoluble granular substance. The main function of melanin is to protect from harmful agents, primarily UV radiation, but also from oxidation, heavy metals, etc. In this volume, chapters deal with production of melanin in human oral mucosa (Liviu et al.), the regulation of melanin action (Cecile et al.), production and potential technological application of fungal melanins (Pombiero-Sponchiado et al.) and an innovative method for measuring melanin in various samples (Zdybel et al.). In conclusion, this volume presents various biological and industrial aspects of melanin production, uses and analysis.

Structural colorations originate from self-organized microstructures, which interact with light in a complex way to produce brilliant colors seen everywhere in nature. Research in this field is extremely new and has been rapidly growing in the last 10 years, because the elaborate structures created in nature can now be fabricated through various types of nanotechnologies. Indeed, a fundamental book covering this field from biological, physical, and engineering viewpoints has long been expected.Coloring in nature comes mostly from inherent colors of materials, though it sometimes has a purely p

Why do visual signals have the characteristics that they do? Why do animals (including man) gesture, posture, and move in communicative fashions? Why are animals colored and patterned in particular ways? Optical Signals is the first attempt to answer these and related questions. After presenting a synthetic framework of social communication, ethology, mathematical information theory, and semiotics, Hailman explains the relevant background: considerations of the physics of light that carry information from sender to receiver, and properties that limit the receiver's ability to get and send information encoded in light. Next Hailman puts together data from different disciplines in order to discover the "design characteristics" of optical signals. The major part of the book concerns these design characteristics and factors that influence them: behavioral patterns and coloration that look like visual signals but are not, principles of visual deception, and the way in which the physical and biological environment structures the characteristics of signals. Lastly, the book considers how the message being transmitted influences the design of the signal itself.
