R-Selection

R-Selection (Rabbit)

The "r/K selection (opportunistic/equilibrium) theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring". r-strategists prefer to focus on producing many offspring. They emphasize higher growth rates on less-crowded ecological niches, which result in the offspring having low probabilities of reaching adulthood. r-selection is most used in unstable environments in order to reproduce quickly and maintain population numbers rather than to focus on survival.
