Reproductive success improves after a single generation in the wild for descendants of some hatchery-origin Chinook salmon

Researchers who created “family trees” for nearly 10,000 fish found that first-generation, wild-born descendants of hatchery-origin Chinook salmon in an Oregon river show improved fitness.

Hypoxia is widespread and increasing in the ocean off the Pacific Northwest coast

Low oxygen conditions that pose a significant threat to marine life are widespread and increasing in coastal Pacific Northwest ocean waters as the climate warms, a new study shows.

Marine heat waves disrupt the ocean food web in the northeast Pacific Ocean

Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.

Oregon State leads effort to expand ocean oxygen monitoring sensor use in fishing industry

Even very low levels of pesticide exposure can affect fish for generations, study finds

Fish exposed to some pesticides at extremely low concentrations for a brief period of time can demonstrate lasting behavioral changes, with the impact extending to offspring that were never exposed firsthand, a recent study found.

Marine heat waves trigger shift in hatch dates and early growth of Pacific cod

Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study from Oregon State University shows.

Scientists outline a bold solution to climate change, biodiversity loss, social injustice

CORVALLIS, Ore. – An international team of scientists led by Oregon State University researchers has used a novel 500-year dataset to frame a “restorative” pathway through which humanity can avoid the worst ecological and social outcomes of climate change.
