Analyzing fish skull development and evolutionary success

Jim Coopere holding a fish tankA biology researcher at WSU Tri-Cities aims to pinpoint underpinnings of evolutionary success by analyzing the skull morphology of a handful of fish species.

“One-third of living vertebrates belong to two fish lineages that independently evolved the ability to project their upper jaws forward from the face during feeding,” said Jim Cooper, assistant professor of biological sciences. “This jaw protrusion has been massively important to » More …

Salmon face double whammy from toxic stormwater

SalmoWSU researchers have found that salmon face a double whammy when they swim in the stormwater runoff of urban roadways.

First, as scientists learned a couple years ago, toxic pollution in the water can kill them. WSU researchers have now determined that fish that survive polluted stormwater are still at risk.

Experiments on both larval zebrafish, a model for salmon, and actual coho salmon showed that toxic runoff can also damage hair-like sensors the fish use to find food, sense predators, and find their way in the current. » More …
