Sample sizes are in parentheses. migrant behavior was assumed to be negligible, and results between streams were comparable without adjustments. Steelhead from our study streams may have evolved migratory strategies whereby expression of temporal differences is dependent on the outcome of tradeoffs between the energetic costs of protracted stream life (increased freshwater mortality) versus the potential benefits associated with larger size at outmigration (increased marine survival). If a population has either exceeded the carrying capacity of its habitat ( over seeding) or had its habitat altered.
