Many organisms use day length as a cue for synchronizing their life cycles with seasonal changes in environmental productivity. Under rapid climate change, however, responses to day length may become maladaptive, and photo‐responsive organisms may only be able to evade increasingly unsuitable habitats if they can accommodate to a wide range of photoperiodic conditions. A previous experiment showed that the pied flycatcher, Fic...

Although the European blackbird, Turdus merula , is one of the most abundant and conspicuous songbirds of the Western Palaearctic and, as such, has been subject of numerous behavioural and ecological studies, there is to date no specific, PCR-based marker system for this species, and information on the applicability of genetic markers from other species or genera is scant. Here, we report the successful amplification of eight...
