Effects of Lateral Hydrological Connectivity on the Taxonomic and Functional Structure of Fish Communities in Saône River Floodplains (France): Implications for Non‐Native Species Distribution

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Large alluvial plain rivers provide a complex mosaic of freshwater habitats characterised by a lateral hydrological connectivity (LHC) gradient between the main channel and floodplains. This connectivity plays a key role in structuring aquatic communities, influencing species distribution, diversity, and ecosystem processes.

Vision in the Southern Hemisphere Lamprey Mordacia Mordax: Spatial Distribution, Spectral Absorption Characteristics, and Optical Sensitivity of a Single Class of Retinal Photoreceptor [PDF]

, 2004
The dorso-laterally located eyes of the southern hemisphere lamprey Mordacia mordax (Agnatha) contain a single morphological type of retinal photoreceptor, which possesses ultrastructural characteristics of both rods and cones.

Effects of Heat Stress on the Fat Greenling (Hexagrammos otakii) Necroptosis Mediated by MLKL and Heart Injury

Aquaculture Research, Volume 2026, Issue 1, 2026.
Mixed lineage kinase domain‐like pseudokinase (MLKL) is a key effector of necroptosis. We identified an MLKL homologue from Hexagrammos otakii, named HoMLKL. The open reading frame (ORF) of HoMLKL contained 1497 nucleotides and encoded a protein with 498 amino acids (Mw = 57.15 kDa). Bioinformatic analysis revealed that HoMLKL is highly conserved.

Will a Fish's Perspective Improve the Ecological Relevance of River Connectivity Metrics?

River Research and Applications, Volume 41, Issue 10, Page 2248-2259, December 2025.
ABSTRACT Structural indices of aquatic connectivity typically focus on the spatial arrangement of barriers to fish movement. Here, we describe a method that adapts the widely applied structural Dendritic Connectivity Index (DCI) into a functional index (DCIF) that constrains connectivity measurements to biologically relevant scales (e.g., based on fish

Evolution of the vertebrate claudin gene family: insights from a basal vertebrate, the sea lamprey [PDF]

, 2016
Claudins are major constituents of tight junctions, contributing both to their intercellular sealing and selective permeability properties. While claudins and claudin-like molecules are present in some invertebrates, the association of claudins with ...

Can the mitochondrial malondialdehyde content be an useful tool to distinguish ecological quality of Petromyzon marinus habitat? [PDF]

, 2014
The sea lamprey is an anadromous species that migrates twice during its life cycle between freshwater and seawater. Microphagous larvae generally spend 4–5 years burrowed in the substrate of rivers and streams before undergoing metamorphosis that ends ...

Ancient evolutionary origin of vertebrate enteric neurons from trunk-derived neural crest [PDF]

, 2017
The enteric nervous system of jawed vertebrates arises primarily from vagal neural crest cells that migrate to the foregut and subsequently colonize and innervate the entire gastrointestinal tract.

Sea lamprey enlightens the origin of the coupling of retinoic acid signaling to vertebrate hindbrain segmentation

Nature Communications
Retinoic acid (RA) is involved in antero-posterior patterning of the chordate body axis and, in jawed vertebrates, has been shown to play a major role at multiple levels of the gene regulatory network (GRN) regulating hindbrain segmentation. Knowing when

Isolation, partial purification, and characterization of a novel petromyzonol sulfotransferase from Petromyzon marinus (lamprey) larval liver

Journal of Lipid Research, 2004
We have isolated, partially purified, and characterized the 5α–petromyzonol (5α-PZ), (5α-cholan- 3α, 7α, 12α, 24-tetrahydroxy-) sulfotransferase (PZ-SULT) from larval lamprey liver.
