About the research project

Novel infectious diseases can cause high mortality in the host animal leading to severe population decline. Tasmanian devils have suffered more than 80% population decline across their range in the last 25 years due to a rare, fatal transmissible cancer – devil facial tumour disease (DFTD). DFTD is spread by biting and kills most devils once they reach sexual maturity as they bite each other during the mating season. Extreme adult mortality will create strong evolutionary selection pressure and we expect that both devils and their tumours will evolve towards an endemic state in which they coexist with potential recovery of the devil population. Population decline has now stabilised, and devils persist in long-diseased areas of Tasmania. Devils are evolving resistance to the disease, and their dispersal patterns, life history and behaviour are changing. There appears to be a reduction in aggression, which may reduce the chance of becoming infected.

The project will show how severe and sustained population decline affects the social organisation, the mating system, sexual selection in and behaviour of the Tasmanian devil. We will use a large pedigree of a wild population that has been monitored for 23 years to test whether these social and behavioural changes are heritable and whether the attributes of individuals and lineages adapt them better to the disease. The project will involve field trapping of Tasmanian devils and construction and analysis of a large pedigree data set derived from genomics. The study site and Tasmania are beautiful and the site and methods are established. The project is part of an international collaboration and will imbed the student in a multi-disciplinary team with regular meetings of investigators and other students in Australia and the US. The supervisory team covers the range of speciality expertise in ecology, genomics and mathematics required for the project.
