What does the term "iteroparous" refer to in evolutionary biology?

The term "iteroparous" in evolutionary biology refers to organisms that reproduce multiple times throughout their lifetime. This reproductive strategy allows iteroparous species to invest in several breeding events, which can enhance their chances of passing on their genes over time. Iteroparity typically occurs in environments where survival conditions can be variable, allowing for multiple opportunities for reproduction.

In contrast, reproductive strategies like semelparity, which describes organisms that reproduce only once in their lifetime, showcase a different adaptation to environmental pressures. Iteroparous species can have a more flexible approach to reproduction, where they can capitalize on favorable conditions at different times, which may increase their overall reproductive success.
