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 ...

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.

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).

Pigment pattern formation in the medaka embryo [PDF]
Pigment Cell Research, 2005 SummaryFor the study of development of pigmentation, compared with mammalian models, fish offer the advantage of multiple chromatophore types and ready access to the developing embryo for observation and experimental manipulation. Compared with zebrafish embryos, medaka embryos have an additional unique chromatophore‐type and superb properties for ...

The multifocal pattern electroretinogram in chloroquine retinopathy [PDF]
, 2004 Purpose: Optimal screening for ocular toxicity caused by chloroquine and hydroxychloroquine is still controversial. With the multifocal pattern electroretinogram (mfPERG), a new electrophysiological technique has recently become available to detect early

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 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.

Advancing biology through a deeper understanding of zebrafish ecology and evolution
eLife, 2015 Over the last two decades, the zebrafish has joined the ranks of premier model organisms for biomedical research, with a full suite of tools and genomic resources. Yet we still know comparatively little about its natural history.
