An opportunistic life history is based on the production of a large number of offspring during a single reproductive episode. This is usually exhibited by small species that mature rapidly. In this type of life history low numbers of offspring usually survive and population size fluctuate dramatically. In variable environments many individuals reproduce when conditions are good; many die without reproducing when conditions are bad. Natural selection has emphasized the production of large numbers of offspring in these organisms rather than individual survival. ...
