However, warmer springs appeared to moderate the impact of salmon abundance, possibly through increased runoff due to increased glacial melt. Three hypotheses have been raised to explain this general phenomenon: the experience hypothesis based on age-specific reproductive experience, the effort hypothesis based on age-specific reproductive effort, and the selection hypothesis based on progressive disappearance of phenotypes due to variation in individual productivity and survival.
