Pigments, Patterns, and Fish Behavior [PDF]
Zebrafish, 2008 Color patterns in fish are often multicomponent signals, composed of pigment-based and structural color patches that can be used to communicate within species, in both inter- and intrasexual interactions, and between species. In this review, we discuss some of the roles played by pigment-based elements of color pattern.

Multiple pigment cell types contribute to the black, blue, and orange ornaments of male guppies (Poecilia reticulata). [PDF]
PLoS ONE, 2014 The fitness of male guppies (Poecilia reticulata) highly depends on the size and number of their black, blue, and orange ornaments. Recently, progress has been made regarding the genetic mechanisms underlying male guppy pigment pattern formation, but we ...

Pigment Melanin: Pattern for Iris Recognition [PDF]
IEEE Transactions on Instrumentation and Measurement, 2010 Recognition of iris based on Visible Light (VL) imaging is a difficult problem because of the light reflection from the cornea. Nonetheless, pigment melanin provides a rich feature source in VL, unavailable in Near-Infrared (NIR) imaging. This is due to biological spectroscopy of eumelanin, a chemical not stimulated in NIR.

Endothelin receptor Aa regulates proliferation and differentiation of Erb-dependent pigment progenitors in zebrafish. [PDF]
PLoS Genetics, 2019 Skin pigment patterns are important, being under strong selection for multiple roles including camouflage and UV protection. Pigment cells underlying these patterns form from adult pigment stem cells (APSCs).

How Much Pigment Should Flowers Have? Flowers With Moderate Pigmentation Have Highest Color Contrast
Frontiers in Ecology and Evolution, 2021 Floral pigments are a core component of flower colors, but how much pigment a flower should have to yield a strong visual signal to pollinators is unknown.

Pigmentation and color pattern diversity in Odonata
Current Opinion in Genetics & Development, 2021 The order Odonata (dragonflies and damselflies) comprises diurnal insects with well-developed vision, showing diverse colors in adult wings and bodies. It is one of the most ancestral winged insect groups. Because Odonata species use visual cues to recognize each other, color patterns have been investigated from ecological and evolutionary viewpoints ...

Pigment pattern in jaguar/obelix zebrafish is caused by a Kir7.1 mutation: implications for the regulation of melanosome movement. [PDF]
PLoS Genetics, 2006 Many animals have a variety of pigment patterns, even within a species, and these patterns may be one of the driving forces of speciation. Recent molecular genetic studies on zebrafish have revealed that interaction among pigment cells plays a key role ...
