Ekologie a chování dvou evropských druhů lindušek

Petrusková, Tereza

Brief overview of the thesis The thesis consists of íntroductionand five chapters (four published articles and one unpublished manuscript), which deal with two topics unified by the studied species. The first part of the thesis focuses on mechanisms allowing coexistence of tree and meadow pipits, and on the territorial and aggressive behaviour of meadow pipit males. The second part of the thesis analyzes tree pipit song and singing behaviour. Short introduction to the first part presentsbríefbackground on mechanisms allowing coexistence of closely related territorial bird species, and first two chapters focus on local co- occunence of ecologically and morphologically very similar congeneric species: the tree pipit (Anthus trivialis) and the meadow pipít(A. praten'sis).First, we evaluate habitat preferences of these species in syntopy and on two allopatric localities, and show that both species select different habitats in coexistence. ln the next chapter,we test by playback experiments for the presence ofinterspecific territoriality, and conclude that habitat preferences,and not interspecific aggression, are important for territorial selection of the two studied species. In addition, we demonstratethat overexcitation by conspecific song is a factor strongiy influencing behaviour of testedanimals, and...
