Assignment - Salmon life history

Life History Evolution
Pick one of the four scenarios given below:

• Egg size increases with female size.
- This means that 2SW salmon will produce offpsring that have higher fitness
- This means lower FW1 - SW1 mortality, and thus higher SW1 proportion

• Habitat availability and competition during spawning.
- Competition might result in 2SW females outcompeting 1SW individuals since they are larger (increasing SW1 mortality)
- Or maybe this could result inmore SW1 if they can access more small streams that have less competiton (expand intonew habitats)

• Genetic correlation between age-at maturity & behavior.
-
• Iteroparity exists in the population and is genetically correlated to early maturation.

• Early maturing individuals will be able to reproduce again, so we would expect
