Variance components and ratios of variance components (±s.e.) of curvilinear sperm velocity of 10 908 spermatozoa from 582 video takes from 84 video recordings of 28 experimental willow warbler Phylloscopus trochilus experimental ejaculates/males in three experimental media of different viscosities (cellulose concentrations). Estimates are from a multi-response mixed model under a character-state approach (see methods for details).
