Bluethroat (Luscinia svecica) Science Article 8 abstract Ecological factors may affect levels of extra-pair paternity (EPP) by influencing the costs and benefits of extra-paircopulation. During a 10-year study of a Norwegian bluethroat population, the frequency of EPP has varied extensively (8%-76% nests with EPP, 7%-33% extra-pair offspring among years). Here, we investigate whether socio-ecological factors(breeding […]

Avian Clock gene polymorphism: evidence for a latitudinalcline in allele frequencies
Bluethroat (Luscinia svecica) Science Article 17 abstract In comparison with most animal behaviours, circadian rhythms have a well-characterizedmolecular genetic basis. Detailed studies of circadian clock genes in
Ultraviolet colour vision and ornamentationin bluethroats
Bluethroat (Luscinia svecica) Science Article 18 abstract Many birds see in the ultraviolet (300^400 nm), but there is limited evidence for colour communication (signalling by spectral shape independently of brightness) in this hidden’ waveband. Such data are critical for the understanding of extravagant plumage colours STAFFAN ANDERSSON AND TROND AMUNDSEN, Proc. R. Soc. Lond. B […]

Wintering and migration of Bluethroat Luscinia svecica in central Spain
Bluethroat (Luscinia svecica) Science Article 2 abstract Aims: Birds have been able to change their breeding and wintering areas by tracking variation in different conditions. In the last decades, the winter distribution of the Bluethroat had been changing. This passerine winters mainly in Africa, although observations of birds wintering in Iberia have increased since the […]
Senior and junior nestlings in asynchronous bluethroat broods differ in their effectiveness of begging
Bluethroat (Luscinia svecica) Science Article 4 abstract In accordance with theoretical models of begging as an honest signal, empirical studies have found that begging by nestlings reflects need and that parent birds respond to variation in begging activity. However, parent birds hatch their broods asynchronously and the resulting within-brood size-asymmetries might induce differences in the […]
Intraspecific variation in sperm length in two passerine species, the Bluethroat Luscinia svecica and the Willow Warbler Phylloscopus trochilus.
Bluethroat (Luscinia svecica) Science Article 10 abstract Sperm cells are highly diversified in birds and considerable research effort has focused on variation in sperm morphology between species. However, surprisingly little is known about intraspecific variation in sperm morphology in birds. We analyzed between- and within-male variation in total sperm length in two passerine species, the […]
