| Abstract: | Mate choice is common in most animals, but the issue has largelybeen ignored in regard to pelagic copepods—the most abundantzooplankton group in the oceans. Contemporary demographic modelsof copepods assume that all encounters lead to successful copulationand viable egg production. We revisit the subject of copepodmating biology in the framework of sexual selection theory.We discuss, and point to, examples that suggest mate choicein both sexes. Sexual selection theory may add an importantdimension for understanding copepod population dynamics andpotentially lead to renewed interpretations of the diverse copepodbehaviours and life histories. In addition, the range of matingstrategies in copepods represents a rich, but unexplored, sourceof information for general behavioural ecologists. |
