Předběžná náplň práce

1. Bird song variations along environmental gradients and its role in spatial segregation of closely related species
The aim is to investigate the song structure (song convergence or divergence) of two nightingale (Luscinia spp.) species in their hybrid zone and mechanisms underlying the song variation in allopatry and sympatry (genetic introgression, heterospecific song learning).
2. Seasonality of song rates in tropical rainforest birds
The aims of this objective will be to estimate year-round seasonality of singing rates (a possible proxy of breeding seasonality) of birds in afrotropical rainforest and to study the intraspecific variation in annual singing activity of selected bird species along an environmental gradient (elevation).
