Bluethroat (Luscinia svecica) Science Article 15 abstract We tested the use of amplified fragment length polymorphism (AFLP) to assess the frequencyof extra-pair parentage in a bluethroat (Luscinia svecica namnetum) population.Thirty-six families totalling 162 nestlings were analysed. Using a combination of threeprimer pairs, we reached an exclusion probability of 93% for the population. S. QUESTIAU, M.C. […]

Bluethroat (Luscinia svecica) Science Article 16 abstract Females in several sexually dimorphic species with conventional sex roles possess ornamental traits that resemble those found in males. The evolution of such traits, however, is still poorly understood. P.T. Smiseth and T. Amundsen, Behav Ecol Sociobiol (2000) 47:205-212 Download article download full text (pdf)

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 […]

Bluethroat (Luscinia svecica) Science Article 7 abstract Extra-pair copulations (EPCs) can create or intensify sexual selection and, provided that fertilisation success is related to phenotypic traits, help explain sexual dimorphism in socially monogamous species. Previous experimental manipulations of the ornamental coloration in male bluethroats, Luscinia s. svecica, have shown effects on their social mating success, […]

Bluethroat (Luscinia svecica) Science Article 14 abstract Between 1984 and 2002,a total of 7643 Bluethroats were ringed and 1054 of these were recaptured at the International Birding and Research Center (IBRCE) in Eilat,Israel (29 33 N, 34 57 E).

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

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 […]

Bluethroat (Luscinia svecica) Science Article 19 abstract Im Fruhjahr 2001 wurde in Niedersachsen eine landesweite Bestandserfassung des Blaukehlchensdurchgefuhrt, bei der neben der Inventarisierung moglichst aller Vorkommen und derenaktueller Bestandsgro

Bluethroat (Luscinia svecica) Science Article 20 abstract El Pechiazul (Luscinia svecica) es quiza el unico paseriforme de nuestra region que presenta una gran variacion en el plumaje, tanto entre subespecies como entre individuosde la misma poblacion.

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 […]
