The NRM Science Conference is fast approaching, don’t forget to register your attendance now!
A new strain of RHDV (the rabbit calicivirus) is on the move in South Australia right now and we're very keen to find out more about what it is doing and how different it is to the usual strain. We'd really appreciate any reports of mysteriously dead rabbits - they usually look more or less like they've just fallen asleep on the ground, with no obvious wounds unless a scavenger has got to them. Rabbits that have died from myxomatosis on the other hand tend to have puffy sores around the face. If you find a mysteriously dead rabbit like this please give David Peacock a call on 08 83039504 or 0417355498. If you're happy to put the rabbit in the freezer or at least some place protected from scavenging foxes then we can organise to get hold of it for samples, so that we can verify whether the cause of death was this new RHDV strain.
Invasion Biogeography & Quantitative Ecology
Human actions have contributed to pervasive changes in biodiversity at a variety of scales through the dual processes of species extinction and introduction. We are interested in the use of invasive vertebrate populations as models for studying the flexibility in behavioural and physiological traits during the invasion process. All projects will be well-supported logistically and the development of individual research projects, to match the students’ interests, will be particularly encouraged.
Our lab has strong research and collaborative funding ties with Biosecurity SA and the quantitative sciences and invasive species groups in the Australian Bureau of Agricultural and Resource Economics and Sciences. We are participating members of the Invasive Animals CRC. Scholarships are available for candidates with particularly strong academic records.
A number of projects are available in Animal Behaviour and Physiology, Biosecurity Risk and Policy, Invasive Species Biology, Global Change Ecology, and Biogeography. Examples of some of these are listed below:
Project: Distribution and habitat preferences of overabundant vertebrate pests
South Australia has a number of over-abundant (exotic and native) vertebrate pest species. These species include over-abundant native marsupials (Kangaroo Island), pest birds (Fleurieu Peninsula), marine mammals (Coorong). These projects will work with state and local Government agencies and stakeholder groups to determine the distribution and habitat preferences of over-abundant species and the impacts that these populations are having on other species and native communities. Guidelines for their future management will be developed. The suitable candidate should be prepared to undertake a project with both intensive field and quantitative components.
Project: The role of insect vectors in the spread of Rabbit Haemorrhagic Disease Virus (RHDV)
The rabbit (Oryctolagus cuniculus) is one of the most abundant pest species in Australia causing considerable ecological and economic damage. The biological control agent Rabbit Haemorrhagic Disease Virus (RHDV) was initially successful in reducing rabbit numbers. However, in recent years rabbit numbers have increased and there is evidence for adaptation in both, the virus and the host genome. This project will investigate how the disease is transmitted between rabbit populations and what role the likely insect vectors (blowflies) have in the seasonal variability and timing of RHD outbreaks.
Project: Monitoring of threatened species in the Mount Lofty Ranges
Effective conservation of threatened species relies on an adequate and reliable knowledge of their distribution. Threatened species are usually sparsely distributed and their populations are localised, resulting in challenging situations to conduct essential monitoring programs. The project will examine different methods and techniques for obtaining reliable information about the status of a vulnerable bird species (Zoothera lunulata halmaturina) in the Mount Lofty Ranges. The results would be of interest not only for the management of the particular study species, but also to a broader audience of both researchers and managers. The suitable candidate should be prepared to undertake a project with both intensive field and quantitative components.
What a year 2015 has been! Our honours students have been awarded with First Class results after successfully completing their theses, while our new and continuing PhD students have been busy with field work and presenting at conferences. We would like to congratulate Dr Su Shan and Dr Ellie Dyer on their outstanding efforts, having successfully completed their PhD candidatures this month. It has been a pleasure to have had them both as part of the Invasion Ecology Group and we wish them all the best in their future endeavours.
