Ecology of freshwater climate refugia

Ecology of alpine and subterranean fresh waters: potential climate refugia for cold-adapted species?

Degree type

PhD

Closing date

Campus

Citizenship requirement

Domestic / International

About the research project

Freshwater biodiversity are among the most heavily impacted by anthropogenic disturbances. This is expected to intensify as climate change alters the temperature, flow, and biogeochemistry of freshwater bodies. Cold-adapted species are likely to be especially vulnerable as they become increasingly restricted to habitats that serve as climate refugia. Identifying, understanding, and managing these refugia could therefore be pivotal to mitigating climate change impacts.

Alpine tarns and subterranean pools are among habitat types that may provide refuge to heat-intolerant species. This is consistent with the distribution of cold-adapted "living fossils" such as the Tasmanian mountain shrimps. However, information about the ecology of these uniques ecosystems and the animals that inhabit them, remains scarce. This project will focus on:

  1. What supports the food webs and how might this be affected by a changing climate;
  2. What are the environmental drivers of key biogeochemical processes (e.g., carbon dynamics);
  3. Susceptibility of alpine and subterranean aquatic fauna to climate change.

The candidate will be based at the University Tasmania in Hobart, supervised by Dr Jia-Huan Liew and A/Prof Leon Barmuta.
