Invading a stable structured population
While most species are iteroparous, reproducing multiple times throughout life, there are a variety of semelparous species, such as cicadas, Pacific salmon, annual plants, etc., which only reproduce once. To investigate whether there is an advantage in a species being iteroparous or semelparous, we look specifically at whether one holds an advantage when invading a population. We analyze the invasion by both types into a stable resident population through a bifurcation approach using a structured population model.
