Chemical come-on successfully lures lovesick lampreys to traps

EAST LANSING, Mich. A synthetic chemical version of what male sea lampreys use to attract spawning females can lure them into traps and foil the mating process of the destructive invasive species, according to Michigan State University scientists. Pheromones, chemical scents used to attract a ...

Leading lampreys to slaughter: Pheromone for scourge of Great Lakes identified

For the rats of Hamelin, it was the Pied Piper's tune. For the destructive sea lamprey of the Great Lakes, it's a chemical attractant, or pheromone, released by lamprey larvae living in streambeds. Following the pheromone trail, adults are drawn to streams favorable for spawning. Researchers have l...

...linkages within the network at early stages," Bronner-Fraser says. "Because the neural crest cell type represents a vertebrate innovation, our work in lampreys shows that this network is ancient and tightly conserved to the base of vertebrates," she says.
