B416: Avian brood parasitism as a model system for studying maternal effects in host populations (Lead Supervisor: Andrea Manica, Zoology)

Supervisors: Andrea Manica (Zoology) and Will Feeney (University of Queensland

Importance of the area of research:

The interactions between avian brood parasites, such as cuckoos, and their hosts present tractable model systems for studying co-evolutionary processes under natural conditions.

Project summary:

Unlike most birds, which build nests and tend to their offspring, brood parasites exclusively lay their eggs in the nests of other birds, and abandon the care of their young to the host. Hosting a brood parasite is costly and selects defences. In turn, this selects counter-adaptations in the parasites, further counter-adaptations in the hosts, and so on: a coevolutionary  €œarms race €. Hosts are known to actively defend against brood parasites. However, whether the threat of brood parasitism affects subtler phenotypes in hosts, such as their investment in offspring (i.e. maternal effects) remains unknown. Using a combination of phylogenetic comparative analyses, long-term monitoring of host populations and field experiments, we will investigate whether the threat posed by brood parasites influences maternal investment by host individuals and populations.

What the student will do:

This project involves a combination of collecting and analysing field data, both correlational and experimental, as well as using phylogenetic comparative analysis.
