In which reproduction pattern do organisms breed over distinct seasons?

Seasonal iteroparity is a reproduction pattern where organisms breed during specific seasons rather than throughout the year. This is often advantageous as it allows organisms to time their reproductive efforts to coincide with optimal environmental conditions, ensuring better survival rates for their offspring. For instance, many animals breed in spring when resources are abundant, thus increasing the likelihood that their young will survive to maturity.

This strategy contrasts with continuous iteroparity, where organisms can reproduce multiple times throughout the year regardless of seasonality, and semelparity, where organisms breed only once in their lifetime. R-selected reproduction refers more broadly to a reproductive strategy characterized by high fecundity and low parental investment, but it doesn't specifically relate to the seasonal aspect of breeding. Therefore, seasonal iteroparity is the most accurate choice for organisms that breed over distinct seasons.
