Usually, the oocyte diameter-frequency distribution analysis for semelparous species exhibits a single bell curve, showing only one modal value.
Now, turning to the semelparous case with nonlinear fecundity element and constant survival probabilities a rather peculiar phenomenon has been detected, compare [4].
In our last example, we consider a semelparous population model where we assume density dependence both in the fecundity and in the survival terms.

Additionally, chum salmon are semelparous and cease feeding activity before the initiation of upriver migration for spawning.

As a consequence of the huge reproductive effort, most Agave species (at least in the non-herbaceous taxa) are monocarpic (semelparous), they die shortly after reproduction (Eguiarte et al., 2000; Good-Avila et al., 2006; Rocha et al., 2006).

Some of these 'semelparous' species flower and die synchronously, and in spatio-temporal waves, such as happened with Bambusa arnhemica.
These squids normally exhibit complex population structures in association with geostrophic currents, protracted spawning, and latitudinal migrations as a strategy to spread--over space and time--the risks of their short, semelparous life cycle (O'Dor, 1998).
Rabidosa rabida is a semelparous species that produces approximately 350 offspring during the female's single reproductive event (Reed and Nicholas 2008).
