Comparative light and electron microscopic studies of dorsal skin melanophores of Indian toad, Bufo melanostictus [PDF]

, 2014
Indian toad, Bufo melanostictus is an amphibian, which is able to change the body color to adapt to its ambient need. This ability is due to specialized skin pigment cells known as melanophores which are excellent animal-cell models to study most of the ...

Hierarchical Assembly as a Design Principle: Structure–Property Relationships Linking Biological Architectures to Functional Aggregate Materials

Aggregate, Volume 7, Issue 9, September 2026.
Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

Signaling for color change in melanophores : and a biosensor application

, 2001
Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells.

The Nature of the Response of Scale Melanophores of the Teleost Fish, Pseudorasbora parva, to Light [PDF]

, 2003
textThe primary color response of innervated and denervated scale melanophores of the adult motsugo, Pseudorasbora parva, was investigated. The intensity of the light used for illumination was about 2,000 ～ 10,000 lux. Innervated melanophores remained in

Ultrastructure of the dermal chromatophores in the Fringe-toed lizard, Acanthodactylus orientalis

Zoologia (Curitiba), 2017
Histology and electron microscopic studies of the dorsal skin of the Fringe-toed lizard, Acanthodactylus orientalis Angel, 1936, showed three types of dermal chromatophores: xanthophores, iridophores and melanophores. These pigment cells were observed in

Evolutionary Reorganization of Transcriptomic Architecture Across a UVB Tolerance Gradient in Fish

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Environmental stress can drive adaptation through changes in transcriptomic organization. Across a UVB tolerance gradient in fish, adaptive responses were associated with increasingly coordinated and functionally specialized transcriptomic networks built upon a conserved functional background.

Taisho-Sanshoku koi have hardly faded skin and show attenuated melanophore sensitivity to adrenaline and melanin-concentrating hormone

Frontiers in Endocrinology, 2022
IntroductionKoi carp, an ornamental fish derived from the common carp Cyprinus carpio (CC), is characterized by beautiful skin color patterns. However, the mechanism that gives rise to the characteristic vivid skin coloration of koi carp has not been ...

Beyond the Classics: The Synergy of AI and Genomics Reveals an Expanded Repertoire of Pigmentation Genes

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 6, Page 475-486, September 2026.
Classical approaches for coloration analysis are limited by human low‐resolution phenotyping and genetic analysis. Artificial intelligence allows us to find genes beyond the tip of the iceberg that explain color and pattern diversity in nature. ABSTRACT Pigmentation has long served as a powerful system for exploring gene–trait relationships, yet much ...

Evolution of Endothelin signaling and diversification of adult pigment pattern in Danio fishes. [PDF]

PLoS Genetics, 2018
Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D.

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

Journal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...
