The contribution of an avian top predator to selection in prey species

Abstract:

Natural selection can vary in magnitude, form and direction, yet the causes of selection, and of variation in selection, are poorly understood. We quantified the effect of a key predator (Eurasian sparrowhawks) on selection on fledging body mass in two bird species (blue tits and great tits). By partitioning selection into within- and between-brood components, we were able to separate individual from brood-level effects of fledging mass on predation probability and recruitment. In blue tits, ...
