K-selection
K-selection Natural selection of those organisms that breed in such a way as to maximize their competitive ability, the strategy of equilibrium species. Most typically it is a response to stable environmental resources. This implies selection for low birth rates, high survival rates among offspring, and prolonged development. K represents the carrying capacity of the environment for species populations showing an S-shaped population-growth curve. Compare R-SELECTION.
