About the research project

Ice free areas in Antarctica are restricted to less than 1% of the total area of Antarctica. These areas are hotspots of biodiversity, supporting diverse flora, fauna and wildlife in terrestrial and coastal marine environments. Life history traits and biodiversity patterns of Antarctic terrestrial meiofauna are poorly understood. Terrestrial meiofauna is comprised of both highly endemic specialized taxa as well as broadly distributed cosmopolitan species. An understanding of the drivers of distributions of individual species, including the role of environmental stressors associated with global human induced pressures (e.g. climate change) are required to enable informed protection of Antarctic biodiversity and broader scale area protection. This understanding of biological response will also inform and allow forecasting of future terrestrial and inshore marine biodiversity patterns under a range of stress scenarios.

As a case study region, the Vestfold Hills, surrounding Davis station, supports a mix of generalist species with widespread distributions and specialist species with more restricted distributions. How these species will likely perform under future environmental pressures will dictate the future biodiversity of the region. Identifying species that are particularly vulnerable, either by their life history traits or their restricted distribution, under future scenarios can inform Antarctic area protection and conservation management practices. These methods will directly inform models and techniques for future studies of inshore marine ecosystems.

The aims of this project are to:

  • Understand the distribution and ecology of Antarctic terrestrial organisms and environmental factors driving their distribution
  • Identify indicator species to be used as markers for community health
  • Determine sensitivity of selected meiofauna to a range of environmental stressors
  • Using derived sensitivity thresholds, forecast future biodiversity patterns for Antarctic terrestrial communities under future climate scenarios
  • Use biodiversity forecasting to inform Antarctic area protection policy

Funding

Applicants will be considered for a Research Training Program (RTP) scholarship or Tasmania Graduate Research Scholarship (TGRS) which, if successful, provides:

  • a living allowance stipend of $28,854 per annum (2022 rate, indexed annually) for 3.5 years
  • a relocation allowance of up to $2,000
