The paper investigates migration patterns and hybridization in Asian stonechats around the Qinghai-Tibet Plateau, finding a migratory divide with hybridization and diverse routes.

The paper examines how urbanisation affects avian malaria in juvenile songbirds, finding that earlier hatching reduces infection risk and urban effects arise from phenological differences.

This study examines how urban environments affect the timing and variability of daily activity in six bird species across different seasons, finding species- and season-specific effects.

This study examines how the timing of social mates affects diel timing variation in great tits and finds that females respond more strongly to their partner's timing than males.

The paper investigates the association between Clock gene polymorphism and annual cycle timing in stonechats across different populations, finding population-specific links between repeat length and timing.

The paper examines genetic diversity and differentiation patterns in stonechats and related species, finding similar genomic regions are important in evolution across independent lineages.
