Density-dependent natural selection and trade-offs in life history traits.

Science (New York, N.Y.) - 26 Jul 1991

Mueller L D, Guo P Z, Ayala F J

Abstract excerpt

Theories of density-dependent natural selection state that at extreme population densities evolution produces alternative life histories due to trade-offs. The trade-offs are presumed to arise because those genotypes with highest fitness at high population densities will not also have high fitness at low density and vice-versa. These predictions were tested by taking samples from six populations of Drosophila...
