Genetic analysis reveals differences in mate choice between wild and hatchery coho salmon

A new study of the genetic profiles of wild and hatchery coho salmon demonstrates important distinctions in how the two types of fish form mating pairs.

 

Non-native fish are main consumers of salmon in reservoirs, researchers find

When warmwater fish species like bass, walleye and crappie that are not native to the Pacific Northwest, but prized by some anglers, overlap with baby spring chinook salmon in reservoirs in Oregon’s Willamette River they consume more baby salmon than native fish per individual, new research found.

Beavers are well established and moving through the Oregon Coast Range, study finds

Beavers are often translocated to restore populations in areas, reduce their conflicts with humans and to take advantage of their ability to improve ecosystems.

Study: Buffer zones, better regulation needed to prevent agricultural pollution in rivers, streams

Greater buffer zones around bodies of water and more consistent enforcement of water protection regulations are needed to reduce agriculture-based pollution in the Western U.S., a recent review from Oregon State University found.

Removal of barred owls slows decline of iconic spotted owls in Pacific Northwest, study finds

A 17-year study in Oregon, Washington and California found that removal of invasive barred owls arrested the population decline of the northern spotted owl, a native species threatened by invading barred owls and the loss of old-forest habitats.

Peace accord in Colombia has increased deforestation of biologically-diverse rainforest

Since the end of the long-running conflict in Colombia, large areas of forest have been rapidly converted to agricultural uses, suggesting the peace agreement presents a threat to conservation the country’s rainforest, a new study from Oregon State University shows.

Partial shade from solar panels increase abundance of flowers in late summer

A new study by Oregon State University researchers found that shade provided by solar panels increased the abundance of flowers under the panels and delayed the timing of their bloom, both findings that could aid the agricultural community.

Master's thesis wins top landscape ecology honor

Oregon State University master’s graduate Kate Halstead has been honored by the North American Chapter of the International Association of Landscape Ecology for her thesis, “Using a species-centered approach to predict bird community responses to habitat fragmentation.”

As lumber prices skyrocket, Oregon State professor develops method to predict future price changes

At a time when lumber prices are skyrocketing, an Oregon State University researcher has developed a new way to predict the future price of logs that uses readily accessible economic information.
