Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Swimming Rhythm Generation in The Caudal Hindbrain of The Lamprey [PDF]

open access: yes, 2018
The spinal cord has been well established as the site of generation of the locomotor rhythm in vertebrates, but studies have suggested that the caudal hindbrain in larval fish and amphibians can also generate locomotor rhythms.

Eco‐Evo‐Hydraulics: Integrating Fish Evolution Into Ecohydraulics for Conservation

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Riverine fish conservation in eco‐hydraulics is often based on restoring or regulating river habitat to a semi‐natural state. For example, ecohydraulic projects support fish populations by increasing river connectivity through fishways, and by maintaining or restoring natural flow variance to enhance habitat quality and availability.

Using structured decision making to evaluate the tradeoffs of selective fish passage

open access: yesConservation Science and Practice, Volume 8, Issue 4, April 2026.
Abstract Dams have dramatically altered rivers and are a major contributor to native fish population declines. However, many dams serve important ecological, social, and economic functions, such as flood control, invasive species control, and provision of recreational opportunities.

Identification of squalamine in the plasma membrane of white blood cells in the sea lamprey, Petromyzon marinus

open access: yesJournal of Lipid Research, 2007
It is well established that innate mechanisms play an important role in the immunity of fish. Antimicrobial peptides have been isolated and characterized from several species of teleosts.

TGF‐β Signaling Plays a Pivotal Role During Developmental Biliary Atresia in Sea Lamprey (Petromyzon marinus)

open access: yesHepatology Communications, 2020
Biliary atresia (BA) is a rare neonatal disease with unknown causes. Approximately 10% of BA cases develop in utero with other congenital defects that span a large spectrum of disease variations, including degeneration of the gall bladder and bile duct ...

DNA Retention in Sea Lamprey Digestive Tracts: Insights From Controlled Feeding Experiments

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Host DNA from a single species was detected via DNA metabarcoding from sea lamprey digestive tracts up to 30 days post‐feeding at 5°C, 10°C, and 15°C. Multiple previous host species could be detected from a single lamprey up to 30 days after fasting at 10°C.

Cellular and Molecular Features of Developmentally Programmed Genome Rearrangement in a Vertebrate (Sea Lamprey: Petromyzon marinus). [PDF]

open access: yesPLoS Genetics, 2016
The sea lamprey (Petromyzon marinus) represents one of the few vertebrate species known to undergo large-scale programmatic elimination of genomic DNA over the course of its normal development.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Introns as Protective Buffers Against Transposable Elements Invasion During Genome Gigantism in a Newt

open access: yesGenes to Cells, Volume 31, Issue 2, March 2026.
In the giant Pleurodeles waltl genome, introns serve as “structural buffers,” absorbing transposable elements (TEs) to protect coding exons. While this enables “gene body inflation,” persistent TE accumulation eventually leads to transcriptional silencing and functional collapse, or “burst,” of the gene architecture.
