Song variation in the Chiffchaff \kur{Phylloscopus collybita}: Song parameters suitable for individual coding
 PRŮCHOVÁ, Alexandra
My study deals with general individual characteristics in songs of a passerine bird species Chiffchaff (Phylloscopus collybita), especially I examines the potential of these characteristics for application in acoustic monitoring of bird individuals. I have found that Chiffchaffs have individually distinct songs but unfortunately, song features I measured were not stable in time and hence they would not be suitable for long-term monitoring of individuals. My study suggests that acoustic individual recognition might be challenging in songbird species due to the complexity and plasticity of their song.

The importance of the colour and the spotted pattern in ladybird \kur{Harmonia axyridis} warning colouration.
 PRŮCHOVÁ, Alexandra
Warning meaning of several artificial as well as natural colour modifications of the Harlequin ladybird (Harmonia axyridis) has been tested in experiments with avian predators (Great tit ? Parus major). I was able to show a certain effect of black spots as their presence provided partial protection to the brown form, while the red form was protected even when unspotted.
