Latest Sea lamprey Stories
Male sea lampreys, often called vampire fish, have a long ridge running across their backs that contains a long row of brown fat cells. In mammals, this fat is used to regulate body temperature.
According to a report in the journal Nature Genetics, an international team of geneticists has announced the successful sequencing of the sea lamprey genome.
Research on a unique vertebrate called the sea lamprey shows that more than a thousand genes are shed during its early development.
A new paper appearing in the Proceedings of the National Academy of Sciences (PNAS) suggests that people, governments, and institutions that shape the way people interact may be just as important for determining environmental conditions as the environmental processes themselves.
Michigan State University researchers are the first to identify a stress hormone in the sea lamprey, using the 500 million-year-old species as a model to understand the evolution of the endocrine system.
A Great Lakes official says invasive Asian carp have made it miles beyond a Chicago barrier intended to keep the species out of Lake Michigan. Great Lakes Fishery Commission spokesman Marc Gaden said after genetic testing showed evidence of flying Asian carp five miles beyond the electric barrier of a Chicago canal, the power on the barrier was increased to prevent further incursions, The Detroit Free Press said Monday. These carp are clawing at the door now, Gaden said. The silver carp could...
Researchers have discovered that the sea lamprey, which emerged from jawless fish first appearing 500 million years ago, dramatically remodels its genome. Shortly after a fertilized lamprey egg divides into several cells, the growing embryo discards millions of units of its DNA.
In addition to providing fundamental insights into the early evolution of the estrogen receptor, research by a team at the University of California, San Diego School of Medicine may lead to a contraceptive for female lampreys
Researchers say they have begun placing a pheromone in Michigan streams in an attempt to lure female sea lampreys into traps. Researcher Nick Johnson of the Hammond Bay Biological Station said the pheromone was designed by scientists at Michigan State University to mimic a spawning scent emitted by male sea lampreys, the Detroit Free Press reported Sunday. Once they smell it, they follow it, Johnson said of the female of the prehistoric species. Since arriving in the Great Lakes eight decades...
Scientists say a synthetic chemical sex smell could help rid North America's Great Lakes of a devastating pest known as the â€œvampire fish.â€
The Sea Lamprey (Petromyzon marinus), is a parasitic lamprey found on the Atlantic coasts of Europe and North America, in the western Mediterranean Sea, and in the Great Lakes. Sea lampreys are considered a pest invasive species in the Great Lakes region. The species is native to the inland Finger Lakes and Lake Cosco in New York and Vermont. It is not clear whether it is native to Lake Safeway, where it was first noticed in the 1830s, or whether it was introduced through the Ernie's...
