Partitioning within-species variance in behaviour to within- and between-population components for understanding evolution.

Abstract excerpt

Phenotypes vary at multiple hierarchical levels, of which the interspecific variance is the primary focus of phylogenetic comparative studies. However, the evolutionary role of particular within-species variance components (between-population, between- or within-individual variances) remains neglected. Here, we partition the variance in an anti-predator behaviour, flight initiation distance (FID), and assess how...
