How Can We Protect Salmon from Climate Warming? It Depends on the River

March 8, 2024March 4, 2024 Julia Bebout 0 Comments acclimation, Climate Change, fish ecology, population ecology, salmon

Atlantic salmon (Salmo salar) are sensitive to changes in temperature. To survive, salmon must be adaptable, particularly in a warming and increasingly unpredictable climate. However, little is known about how this culturally valuable fish responds to dramatic changes in temperature.

Habitats are a work of art: habitat mosaics and fish production

June 18, 2019June 18, 2019 Chelsea Barreto 0 Comments biodiversity, environmental science, fish production, salmon

Biodiversity is continually being threatened by human activities, and it is vital that we protect it. Conserving biodiversity means conserving species and the habitats they live in. We know that habitats vary through space and time, but does this variation impact fish production in the long term? Brennen et al. explores this question using Pacific salmon species in an Alaskan watershed.

Using Genetics to Inform Conservation: Spring-Run Chinook Salmon in the Klamath-Trinity River Basin

May 5, 2019May 20, 2019 Maddie Halloran 0 Comments California, Chinook, genetics, Restoration, salmon

The same species of Chinook salmon in the Klamath-Trinity basin return to the river each year in two groups: the fall-run and the spring-run. Spring-run Chinook in the Klamath River have drastically declined from historical levels, and are at much lower abundances than fall-run Chinook there. A key genetic difference between these two runs may determine how they are protected (and hopefully restored) under the Endangered Species Act. Read on to learn more!
