Density-dependent selection and the maintenance of colour polymorphism in barn owls.

Proceedings. Biological sciences - 8 Jun 2022

Kvalnes Thomas, Sæther Bernt-Erik, Engen Steinar, Roulin Alexandre

Abstract excerpt

The capacity of natural selection to generate adaptive changes is (according to the fundamental theorem of natural selection) proportional to the additive genetic variance in fitness. In spite of its importance for development of new adaptations to a changing environment, processes affecting the magnitude of the genetic variance in fitness-related traits are poorly understood. Here, we show that the red-white...
