Iteroparity

Definition

Iteroparity is a reproductive strategy where organisms reproduce multiple times throughout their lifespan. This strategy contrasts with semelparity, where organisms reproduce only once before dying.

5 Must Know Facts For Your Next Test

1. Iteroparous species often invest more in the survival of their offspring through parental care.
2. Examples of iteroparous organisms include humans, most mammals, and many perennial plants.
3. This strategy is advantageous in stable environments where the probability of adult survival is high.
4. Iteroparity allows for flexibility in reproductive timing, which can be beneficial if environmental conditions vary.
5. Energy allocation in iteroparous species is spread out over multiple reproductive events rather than concentrated into a single event.
