| A review of the ecological parameters and implications of subsociality in Parastrachia japonensis, a semelparous species that specializes on a poor resource. |
| Conceptual and mathematical models identify the conditions under which annual semelparity has a selective advantage over perennial iteroparity, where semelparous and iteroparous life histories are discrete alternatives. |
| In many species, semelparous life cycle with unpredictable juvenile causes decreased population size. |
| In semelparous forms, reproduction takes place near the end of the life span, after which there ensues a rapid senescence that quickly leads to the death of the organism. |
| Annual and biennial plants are semelparous, as are many insects and a few vertebrates, notably salmon and eels. |
| Additionally, chum salmon are semelparous and cease feeding activity before the initiation of upriver migration for spawning. |
