A new Hyphessobrycon (Characiformes: Acestrorhamphidae) of the Hyphessobrycon agulha lineage of Hyphessobryconinae from the lower Aripuanã basin, Brazil, with comments about the lineage

Journal of Fish Biology, EarlyView.
Abstract A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.

Charge‐Induced Morphing Gels for Bioinspired Actuation

Advanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Spontaneous melanotic lesions in axillary seabream, Pagellus acarne (Risso) [PDF]

, 2013
In this paper, we describe spontaneous melanotic lesions in the skin of axillary seabream, Pagellus acarne (Risso) from a defined area of the Portuguese Coast, located in Cabo da Roca and Foz do Arelho.

Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...

Enrichment of Neural Crest Cells by Antibody Labeling and Flow Cytometry for Single‐Cell Transcriptomics in a Lizard

Evolution &Development, Volume 28, Issue 1, March 2026.
Using wall lizard embryos, we present an approach to isolate neural crest cells by antibody labeling and flow cytometry followed by single‐cell RNA sequencing. The approach does not require transgenic animals, and thus enables addressing evo‐devo questions across a range of vertebrate taxa.

Epigenetics in Captivity: Restoring Wild Phenotypes in Captive‐Reared Salmonids

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Captive rearing is a common practice for the stocking, conservation, and supplementation of fish species worldwide, but captive‐reared fish can exhibit altered phenotypes leading to reduced fitness in nature compared to wild conspecifics. In salmonids, certain studies have found limited genetic differentiation between wild and captive‐reared ...

Species Delimitation of Argonauta Paralarvae Reveals an Extensive Morphological Variability in the Northern Humboldt Current System

Diversity
Argonauts or paper nautiluses are pelagic octopod cephalopods with a cosmopolitan distribution in tropical and subtropical waters around the world. Unlike other species of octopus, these are characterized by the fact that the female has a shell that ...

Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater

Journal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).
