Thermal Envelopes & Climate Change

Study further tracks the current and potential future distribution of fish and amphibians across the US West.

High Elevation Climate Refuges

A recent study suggests fish habitat is more resilient to climate changes than previously thought.

Migrations and Struggling Salmon as Pacific Warms

Ocean temperatures are projected to rise. Two new studies look at how species could respond.

Juvenile Salmon and Freshwater Acidification

Ocean acidification and its impacts have received a lot of attention recently. However, much less is known about freshwater acidification and its impacts. A new study examines how both freshwater and ocean acidification affects juvenile salmon.

Study Links Salmon Survival to Different Climatic Factor

It’s long been believed the behavior of the Pacific Decadal Oscillation was the best predictor of salmon survival. Now a new paper is suggesting it’s the North Pacific Gyre Oscillation fisheries and biologists should be watching. 

Trout Need Cold, Wide, Connected Waters

As the world warms, many species are migrating, seeking habitat within a temperature range they can tolerate. This movement has involved organisms as different as birds and trees. But not all species are so mobile. This is especially true for freshwater fish, including several species of landlocked trout in the Western United States. The problem:…
