Witryna19 paź 2010 · The specific life history that will evolve by natural selection depends on details such as the different mortality rates and fecundity schedules that accrue to individuals with different ages of maturation. In order to avoid telling just-so stories about the evolution of life history traits, it is important to make predictions and then test them. WitrynaLife history patterns (parity) Parity is the organization of fecundity into two distinct types, semelparity, and iteroparity. Semelparity occurs when an organism reproduces only once in its lifetime, with death being a part of its reproductive strategy.

In ecology, fecundity is a measure of the reproductive capacity of an individual or population, typically restricted to the reproductive individuals. It can be equally applied to sexual and asexual reproduction, as the purpose of fecundity is to measure how many new individuals are being added to a population.
