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 ...

Progressive fate restriction model for iridophore development from eNCCs.

, 2018
We interpret our gene expression and mutant data in the context of a progressive fate restriction model, identifying a series of intermediate stages: early and late Cbl, ib(sp), ib(df) and iph.

Honest signals and sexual conflict: Female lizards carry undesirable indicators of quality

Ecology and Evolution, 2021
Sex differences in animal coloration often result from sex‐dependent regulatory mechanisms. Still, some species exhibit incomplete sexual dimorphism as females carry a rudimentary version of a costly male trait, leading to intralocus sexual conflict. The

Ordered Chaos: Photoreceptor Mosaics in the Larval and Adult Turquoise Killifish (Nothobranchius furzeri)

Journal of Comparative Neurology, Volume 534, Issue 9, September 2026.
The annual turquoise killifish (Nothobranchius furzeri) cone photoreceptor mosaic is an ordered lattice but lacks regularity of cone subtypes in adulthood. The cone mosaic differs between life stages and has characteristics observed in other fishes adapted for life in turbid water.

Variation in pigmentation gene expression is associated with distinct aposematic color morphs in the poison frog Dendrobates auratus

BMC Evolutionary Biology, 2019
Background Color and pattern phenotypes have clear implications for survival and reproduction in many species. However, the mechanisms that produce this coloration are still poorly characterized, especially at the genomic level.

The Ultrastructure of the Spectacle, Cornea and Conjunctiva of the Short‐Nosed Sea Snake Aipysurus apraefrontalis (Elapidae, Squamata) With Particular Reference to the Sub‐Spectacular Space and Its Contents

Journal of Morphology, Volume 287, Issue 9, September 2026.
Using micro computed tomography, light microscopy and transmission electron microscopy, this study reveals that the conjunctival portions of the corneal epithelial and spectacular endothelial lining in the eye of the short‐nosed sea snake Aipysurus apraefrontalis possess high densities of microvilli to increase the surface area and two types of ...

Developmental and Cellular Basis of Vertical Bar Color Patterns in the East African Cichlid Fish Haplochromis latifasciatus

Frontiers in Cell and Developmental Biology, 2020
The East African adaptive radiations of cichlid fishes are renowned for their diversity in coloration. Yet, the developmental basis of pigment pattern formation remains largely unknown.

On the fourth Diadema species (Diadema-sp) from Japan. [PDF]

PLoS ONE, 2014
Four long-spined sea urchin species in the genus Diadema are known to occur around the Japanese Archipelago. Three species (D. savignyi, D. setosum, and D. paucispinum) are widely distributed in the Indo-Pacific Ocean.
