New research: Worth waiting for – The advantages of late-migrating spring-run Chinook
Rare traits and behaviors within a population often get less attention, but might sometimes be the perfect ingredient to ensure the survival of a species in the face of threats like climate change. A recent article published in the journal Nature revealed the surprising success of a rare life-history strategy for threatened spring-run Chinook salmon. Juveniles that spent the summer in cool, high-elevation habitat and migrated in the fall rather than the spring were found to be crucial to the success of the population, especially in years experiencing stressful environmental conditions.
