Seeking applications from highly qualified and motivated candidates for a PhD program of research on the ecological impacts of cat eradication on Christmas
Island. The student will join Eve McDonald-Madden’s group in the Centre for Biodiversity and Conservation Science, University of Queensland, with joint
supervision from Parks Australia staff, and others.
Cats and black rats have had a devastating impact on Christmas Island’s unique ecosystem since their introduction by the first settlers about 125 years ago. Through predation, competition and as vectors of disease, they have contributed (with other threats) to the extinction of four of the five native mammals once found on the island, and the extinction in the wild of three of CI’s five endemic reptile species. They continue to exert pressure on the only remaining native mammal species (the CI flying-fox) and other endemic species like the white-tailed tropic bird, hawk-owl, thrush, emerald dove, goshawk, CI frigatebird and the giant gecko.
In response to the threats posed by cats and rats, Parks Australia has collaborated with other organisations to begin a program that aims to eradicate cats from the island.
However, preliminary qualitative modelling suggests that cat control could result in complex impacts on threatened native species, with the potential for negative impacts arising if cat reduction allows the numbers of black rats to substantially increase.
In this project, the student will work with the cat eradication program to identify and measure key indicator species in the Christmas Island ecosystem that will allow managers to understand, and adapt to, the changes in the community caused by the cat control program. The research is likely to include experimental manipulations of black rats, carried out in tandem with the cat control, to help tease apart the species interactions and thus revise our understanding of the ecosystem model.
The student will be part of a team of managers and researchers who are collaborating to improve conservation outcomes for Christmas Island.
The successful candidate will have skills in vertebrate field ecology and data analysis; experience in decision science would be useful, but not essential.
Closing Date for Applications: 15 April 2016

Karajarri Rangers are leading a Threatened Species Recovery Hub research project to investigate how different fire management approaches affect biodiversity. The first field trip took place in April this year, when a team of 16 rangers, support staff and scientists journeyed to the Edgar Ranges for eight days of wildlife monitoring. Hub researcher Sarah Legge worked with the rangers to compile this report from the field.
Cissy Gore-Birch is a member of the Threatened Species Recovery Hub’s steering committee and the Chair of its Indigenous Reference Group. The Indigenous Reference Group was established to assist hub leaders and project teams to strengthen the engagement and participation of Indigenous people in the hub’s activities and research projects. Cissy recently attended the Species of the Desert Festival on the Paruku Indigenous Protected Area, where she spoke about both threatened and culturally important species, and increasing the voice of Indigenous people in environmental policies and research.
Dr Sally Box, the Australian Government’s Threatened Species Commissioner, talks about the importance of working with Indigenous groups to conserve Australia’s threatened species.
Researchers from the Threatened Species Recovery Hub are calling on citizen scientists to help them learn more about Australia’s possums and gliders by recording sightings in a new, free app. Dr Rochelle Steven from the University of Queensland is passionate about Australia’s possums and gliders and believes people in the community can do a lot to help support conservation, especially in urban areas.
There are 27 different types of possums and gliders in Australia. They have a huge variety of sizes, shapes and appearances. We’ve compiled a profile on every species here. One quarter of our possums and gliders are listed as threatened under Australian environmental law. Help their conservation, be a citizen scientist: you can record sightings of possums from your local areas in the free 'CAUL Urban Wildlife App'.
