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.
