Interactions between brood parasites and their hosts in a heterogeneous landscape

Tildelt: kr 3,3 mill.

Brood parasites and their hosts represent particularly suitable systems for studying the process of coevolution. A number of adaptations and counter-adaptations in hosts and parasites have previously been revealed, but few studies have considered dynamics between and within several host-parasite systems that are sympatric in time and space. Within the frame of this project we want to study in more detail host-brood parasite interactions in an area where the parasite at the species level utilize several ho st species, but individual female parasites apparently have specialized on particular host species. More specifically, we will focus on: 1) level of differentiation of local cuckoo gentes in terms of egg morph distinctiveness, genetic composition and evol ution; and 2) possible factors explaining the pattern of current host selection by the common cuckoo in the region
