Those organisms described as r-strategists typically live in unstable, unpredictable environments. Here the ability to reproduce rapidly (exponentially) is important. Such organisms have high fecundity (glossary) and relatively little investment in any one progeny individual, they are typically weak and subject to predation and the vicissitudes of their environment.
