Expression of sympathetic nervous system genes in Lamprey suggests their recruitment for specification of a new vertebrate feature.

open access: yesPLoS ONE, 2011
The sea lamprey is a basal, jawless vertebrate that possesses many neural crest derivatives, but lacks jaws and sympathetic ganglia. This raises the possibility that the factors involved in sympathetic neuron differentiation were either a gnathostome ...

Contribution of anadromous fish to the diet of European catfish in a large river system [PDF]

open access: yes, 2009
Many anadromous fish species, when migrating from the sea to spawn in fresh waters, can potentially be a valuable prey for larger predatory fish, thereby efficiently linking these two ecosystems. Here, we assess the contribution of anadromous fish to the

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Evolution of vertebrate GnRH receptors from the perspective of a basal vertebrate

open access: yesFrontiers in Endocrinology, 2012
This minireview provides the current status on gonadotropin-releasing hormone receptors (GnRH-R) in vertebrates, from the perspective of a basal vertebrate, the sea lamprey, and provides an evolutionary scheme based on the recent advance of whole genome ...

Bifurcations in valveless pumping techniques from a coupled fluid-structure-electrophysiology model in heart development [PDF]

open access: yes, 2017
We explore an embryonic heart model that couples electrophysiology and muscle-force generation to flow induced using a $2D$ fluid-structure interaction framework based on the immersed boundary method.

Adaptive Capacity of Freshwater Organisms in North America: Current Understanding and Future Applications

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
This paper tailors adaptive capacity understanding for North American freshwater fishes, mussels, and crayfishes by integrating trait‐based approaches to provide practical guidance for improving management and conservation decisions under global change.

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.

Achieving Functionality Targets for Seismically Isolated Steel Buildings Using Gaussian Process Modeling

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
As seismic design paradigms shift toward functional recovery, there is a need for efficient methods to achieve desired decision variables (DVs), such as probability of replacement, repair cost, and downtime of the building, for seismically isolated buildings.

Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and
