- - - - "This “premature migration” reduces growth opportunities at sea, compels them to occupy much less productive freshwater habitats, and exposes them to extremes of flow and temperature, disease, and predation""Consistent with this hypothesis, early return is characteristic of larger, older salmonids (that would benefit less from additional time at sea to grow than would smaller fish)"(Quinn et al., 2016)
- - - - support- If you manipulate egg clutches, there should be an impact of productivity
    - - implications Population Dynamics: Intermediate clutch sizes contribute to stable populations since they maximize reproductive success without overburdening parental care.
        Conservation: Understanding the optimal clutch size for a species can aid in conservation strategies by identifying critical factors that influence reproductive success.
- - - - Survival=body mass determines energy consumption
      - Reproduction=allocate resources in quality of offspring, or quantity (few large or many small)
    - - K-selected species
        
        Habitat: Constant and predictable
        
        Populations tend to be at carrying capacity (k) – so main evolutionary pressure is competition
        
        Evolve to be more competitive in stable habitats. Grow to be larger to compete bette
      - r-selected species
        
        Habitat: Variable and unpredictable
        
        Populations grow (r) at a fast rate – best strategy for variable habitats
        
        Populations can respond to quick environment change (e.g. fires), early age reproduction
      - high allocation to survival at the other (slower population growth) at the other end
      - high allocation to reproduction (and hence fast population growth) at one end
