The Killers of California and Oregon
Thirteen years of photo-identification data of killer whales observed in California and Oregon provide new insights into the distribution and population structure of mammal-eating killer whales in the eastern North Pacific Ocean.
PROFILE: Investigating ocean pollution to “provide solutions, not just answers to questions”
“Anthropogenic stressors are reshaping our ocean – it’s not the same ocean we had 30 or 40 years ago. As academics we need to provide solutions, not just answers to questions.”
St. Lawrence fishery study tests the benefits of collaboration between scientists, government, management and industry members
Researchers had the opportunity to test the usefulness of a fashionable fisheries management tool called management strategy evaluation (MSE).
Partnership between researchers and whale-watch operators makes for big whale behaviour insights
Based on their findings, the researchers recommended that whale-watchers keep some distance from foraging areas to avoid disturbing the whales while they eat.
Ecosystem modelling indicates that adding fertilizer to water reservoirs pays off
In the simulated Arrow Lakes Reservoir, fish fared better when nutrients were added to the water, regardless of whether the water flow was high or low.

GOM took advantage of the COVID-19 pandemic, moving online, and connecting with researchers from 29 countries.
Blue herons identified as a significant juvenile salmon predator
Looking for predators that ate salmon, an Indigenous biologist suggested looking at heron. Discarded tags proved Pacific great blue herons could be scooping up as many as 3-6% of all juvenile salmon.
