Late-migration strategy, although rare, may be key
In late October, a study spotlighting the migration patterns, or life-history strategies, of the spring-run Chinook salmon in California’s Central Valley showed that juveniles that migrate later in the year may have higher survival rates during years with unfavorable living conditions, such as drought. This late-migration strategy, once thought to be a rare behavior among spring-run Chinook salmon, may in fact prove pivotal for the fish population facing an increasing warming climate.
