Brain pathways of the chromatophore system in the squid Lolliguncula brevis

, 1990
Brain pathways controlling the chromatophores of the squidLolliguncula brevis are described using cobalt iontophoresis. The results show several input and output pathways of the anterior and posterior chromatophore and lateral basal lobes.

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.

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 ...

Reconstruction of a Kinetic Model of the Chromatophore Vesicles from Rhodobacter sphaeroides [PDF]

, 2006
We present a molecular model of a chromatophore vesicle from Rhodobacter sphaeroides. These vesicles are ideal benchmark systems for molecular and systemic simulations, because they have been well studied, they are small, and they are naturally separated

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 ...

Phylogeographic Patterns of the Eigenmannia humboldtii Group Shaped by Miocene‐Pleistocene Transitions

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim Eigenmannia is a monophyletic genus of small and medium‐sized fishes known as ‘glass knifefishes’, with a wide distribution throughout the Neotropical region and a complex taxonomic history. This study aimed to investigate the phylogenetic diversification patterns within the Eigenmannia humboldtii species group (specifically E. nigra and E.

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

Journal of Phycology, Volume 62, Issue 4, Page 1185-1192, August 2026.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Description of the Early Development of Hoplias intermedius (Günther, 1864) (Characiformes: Erythrinidae)

Journal of Morphology, Volume 287, Issue 7, July 2026.
This study provides the first description of the early development of Hoplias intermedius (Characiformes: Erythrinidae), from the embryonic to the juvenile stage. The morphological, meristic, and morphometric characterization contributes to understanding the ontogeny and developmental transitions of Neotropical fishes, supporting taxonomy, conservation,
