Semelparity refers to which type of reproduction?

Semelparity refers to a reproductive strategy in which an organism produces all of its offspring in a single reproductive event or season, often followed by death. This strategy is seen in various species, particularly in those that may have high reproductive risks or significant environmental pressures. The primary advantage of semelparity is that it allows the species to take advantage of optimal conditions for breeding at one time, enabling a large number of offspring to be produced simultaneously.

This reproductive approach contrasts with other strategies such as iteroparity, where organisms reproduce multiple times throughout their lives, spreading out their reproductive efforts. In semelparous species, the focus on a single reproductive event can lead to an increase in the number of offspring produced, particularly in environments where survival is uncertain, as it concentrates reproductive resources into one effort.
