Transcriptome Analysis of Sea Lamprey Embryogenesis
<p>The sea lamprey (<em>Petromyzon marinus</em>) has survived throughout evolution for hundreds of millions of years. It is considered an invasive species to the Great Lakes that has caused dramatic changes in the ecosystem for fish communities resulting in the collapse of a fishing industry that …

Movement ecology of two threatened anadromous species, twaite shad Alosa fallax and sea lamprey Petromyzon marinus, revealed by acoustic telemetry.
… as the Alosinae (shads) and Petromyzontiformes (lampreys), for which movements and space use during both freshwater spawning migrations and the marine life-phase is poorly understood, compared with anadromous species of the Salmonidae family. Here, the movement ecology of threatened twaite shad …

Spatial and Temporal Patterns of Anadromous Fish Passage at Boshers Dam Vertical Slot Fishway on the James River, Richmond, Virginia
… of American shad (Alosa sapidissima) and sea lamprey (Petromyzon marinus) passage. The ecological effects of restoring connectivity to upstream habitat for gizzard shad (Dorosoma cepedianum) and blue catfish (Ictalurus furcatus) are also discussed. Regression analysis determined that the …

Glycoprotein hormone receptors in sea lamprey (Petromyzon marinus): Identification, characterization and implications for the evolution of the vertebrate hypothalamic-pituitary-gonadal/thyroid axes
… with the estimated time of divergence of the lamprey lineage, one of the two surviving Agnathan groups (lamprey and hagfishes) in the actual fauna. Therefore, the study of the GpH/GpH-R system in lamprey is of foremost importance for understanding the evolutionary emergence of the HPG and HPT …

DELAYED EFFECTS OF SUB-LETHAL LAMPRICIDE, 3-TRIFLUOROMETHYL-4-NITROPHENOL (TFM), EXPOSURE ON THE METABOLIC PHYSIOLOGY OF JUVENILE LAKE STURGEON (<em>ACIPENSER FULVESCENS</em>)
… at high concentrations used to control invasive sea lamprey (<em>Petromyzon marinus)</em>. Little is known about how TFM would affect juvenile lake sturgeon (age-0) at the sub-lethal concentrations encountered during routine lampricide treatments; specifically, its effects on growth, stress …

Profiling extracellular vesicles signatures and deiminated protein cargo across phylogeny and pilot assessment of in vitro application of EVs in tissue regeneration, with focus on selected taxa displaying unusual immunological properties.
… systems. EV signature profiles of purple sea urchin, sea lamprey and reindeer and their deiminated protein cargoes revealed similarity across species, highlighting the conservation of deiminated proteins involved in epigenetic regulation and innate immune responses across phylogeny. …

Osmoregulatory role of the intestine in fish physiology. Evolutionary, environmental, and toxicant implications
… in the most basal ion- and osmo- regulator, the sea lamprey (Petromyzon marinus), and in a much recent diverged teleost, the Senegalese sole (Solea Senegalensis). Additionally, aquafeeds' effects contaminated with aflatoxin B1 on growth performance and intestinal physiology are also examined, …

Waterfront spectacular
… on two detrimental aquatic invasive species: the sea lamprey (Petromyzon marinus) and zebra mussel (Dreissena polymorpha) and asserts that making work visible, in public, is spectacular—as noted, “a visible deviation from the norm intended to provoke a response.” In conclusion, this thesis …

Hair Bundles of a Jawless Vertebrate Employ Tetrapod-Like Tuned Mechanical Amplification
… the inner ears of two jawless vertebrates, the sea lamprey Petromyzon marinus and the American brook lamprey Lampetra appendix. We observe spontaneous oscillations in both of these animals. In the latter species, we also show evidence that their oscillations stem from mechanisms similar to those …

Suction pressure measurement and behavioral observations of sprawning-run sea lampreys (<i>Petromyzon marinus</i>)
<p>Sea lampreys utilize attachment by suction throughout their life cycle. Despite the importance of this behavior, the role of surface texture in the attachment process has not been fully understood. The goal of this study was to develop a technique to quantitatively examine attachment abilities …

Deciphering the regulatory code driving neural crest evolution and development
… structures including peripheral neurons. The sea lamprey, Petromyzon marinus, is at the base of the vertebrate lineage and offers an ideal model for the ancestral neural crest. Comparisons to the modern neural crest gene regulatory network (GRN) such as that of the chicken can elucidate …

Gonadotropin releasing hormone in agnathans
<p>Hagfish and lampreys are the only two representatives of Agnathans among extant vertebrates. The regulatory hypothalamic neurohormone, gonadotropin-releasing hormone (GnRH), regulates reproduction in all vertebrates through the hypothalamic-pituitary-gonadal axis. Most vertebrates have at least …

Faecal Sediments as Bio-Archives: The Fish Event Horizon in the Low Countries
… including three very rarely reported species: sea lamprey (Petromyzon marinus), worm pipefish (Nerophis lumbricoides) and zander (Sander lucioperca). Overall, however, DNA consistently underperformed in comparison to sieved ichthyological/ zooarchaeological datasets, despite “gold- standard” …
