R-selected Species

Species (such as rats) produced by unstable environments that are opportunistic, grow up quickly, have large numbers of precocial offspring and invest less in each, and exhibit a relatively earlier development of the reproductive system in terms of metabolic energy expended toward organs such as the brain and body. Such r-selected species gain advantage through their ability to reproduce rapidly.

Cf. K-selected species.
