A general model of comparative fecundity for semelparous and iteroparous life histories

, : A general model of comparative fecundity for semelparous and iteroparous life histories. American Naturalist, 1181: 27-36

Previous models of semelparity and iteroparity are discussed. A general model is produced which incorporates population growth rate, juvenile and adult survivorship, prereproductive development time, time between reproductive episodes and senescence. Increasing values of population growth rate and juvenile survivorship favour semelparity.
