Dissecting phenotypic variance in life history traits into its genetic and
environmental components is at the focus of evolutionary studies and of
pivotal importance to identify the mechanisms and predict the consequences
of human-driven environmental change. The timing of recurrent life history
events (phenology) is under strong selection, but the study of the genes
that control potential environmental canalization in phenological traits
is at its infancy. Candidate genes for circadian behaviour entrained by
photoperiod have been screened as potential controllers of phenological
variation of breeding and moult in birds, with inconsistent results.
Despite photoperiodic control of migration is well established, no study
has reported on migration phenology in relation to polymorphism at
candidate genes in birds. We analysed variation in spring migration dates
within four trans-Saharan migratory species (Luscinia megarhynchos;
Ficedula hypoleuca; Anthus trivialis; Saxicola rubetra) at a Mediterranean
island in relation to Clock and Adcyap1 polymorphism. Individuals with
larger number of glutamine residues in the poly-Q region of Clock gene
migrated significantly later in one or, respectively, two species
depending on sex and whether the within-individual mean length or the
length of the longer Clock allele was considered. The results hinted at
dominance of the longer Clock allele. No significant evidence for
migration date to covary with Adcyap1 polymorphism emerged. This is the
first evidence that migration phenology is associated with Clock in birds.
This finding is important for evolutionary studies of migration and sheds
light on the mechanisms that drive bird phenological changes and
population trends in response to climate change.
