Project objectives

Please, notice that this is a summary of the whole project and the scope of PHD student's work will be related only to the implementation of a part of the objectives. A minimum of three other researchers will be involved in this study too.

Trade-off between species recognition and individual discrimination in tropical Turtur doves

Song is a fundamental signal associated with sexual selection in birds. The processes that allow for species recognition as well as for individual recognition are inextricably linked and prercąuisite for subseąucnt decisions about stratcgy of tcrritory dcfcnce and matę choice. The two mentioned functions are somewhat contradictory, as species recognition needs the uniform feature of a song within a species, whereas individual recognition is only possible if individuals within a species are somehow acoustically different. This may lead to conflicting selection pressures that are dependent on the chance of mistaken species recognition and the importance of individual recognition. The problem that we want to deal with in this project is the evolutionary compromise between species specific uniformity and individual-specificity of acoustic signals produced in a sexual selection context. Our model system, the dove species from the Turtur genus inhabit forest-woodland-savanna habitats in Sub-Saharan Africa. Firstly, we want to describe the advertisement song variation among and within all Turtur species, in order to identify species and individually specific song features. Sccond, we want to cxpcrimcntally test how birds respond to songs of the same species and different species in populations occurring allopatrically and sympatrically; and if birds can discriminate between neighbours and strangers and how similar, co-existing species affect this process. We plan to use molecular methods to confirm phylogenetic relatedness among the five species and analyse the genetic structure of same- and dififerent-species populations living in sympatry and allopatry.
