[1] Amount of variation in multiple colouration traits within populations on a large spatial scale in the pied flycatcher (ficedula hypoleuca) / P. M. Sirkiä, P. Adamík, A. V. Artemyev et al. // Ornithological Science. — Vol. 13 of Supplement. — Ornithological Society of Japan Tokyo, Japan, 2014. — P. 159–159. Colour polymorphism with a genetic background provides a visible proxy for genetic differences between populations and for changes in the composition of populations. Colour polymorphism thus presents an excellent opportunity to study evolutionary potential and evolution in action. There are relatively few studies on patterns of colour polymorphism on large geographicalscales and even less attention has been paid to differences in the amount of variation of traits within populations across large scales. Variation around the mean within and among populations is nonetheless interesting as it is the raw material for election. Potential for evolutionary change is largely dependent on the amount of variation present. On the other hand, variation within populations can reflect selection history. We analysed standardised data on male plumage colouration of the Pied Flycatcher from 19 populations across the breeding range. In this species males display multiple apparent ornaments, such as melanin-based dorsal colouration, a whiteforehead patch, and conspicuous white wing and tail patches. We were particularly interested in analysing the amount of variation in multiple phenotypic traits within populations across the breeding area. We studied the relationships between the coefficients of variation within populations, mean colouration traits and current selection on these traits. In addition, we investigated associations between the amount of variation in multiple colouration traits and variation in environmental conditions. We discuss the roleof the amount of variation in plumage olouration reflecting evolutionary potential, the underlying processes leading to geographic variation, and what we can learn from large scale studies on colour polymorphism.
