Effects of the Anthropocene on Australian frog species

As human activities rapidly alter ecosystems across the globe, we need to understand how species are responding and/or adapting. Although seemingly well documented, how biodiversity is responding to anthropogenic change is relatively unknown. For amphibians, a taxon under immense threat globally, understanding their responses is crucial. As such, my PhD (in conjunction with the Australian Museum Research Institute) broadly aims to understand how Australia’s frog species are responding to challenges of the Anthropocene, and more specifically:

  • Characterise the habitat of urban biodiversity hotspots that maximises frog diversity and threatened species presence in urban and suburban areas
  • The effect urbanisation has on acoustic communication/mating behaviour in frogs
  • The effect of urbanisation on disease susceptibility of Australian frogs through investigations of changes in their skin microbiome and immune system
  • The effect of climate change on frog morphology, and persistence of Australian frog species in fire affected areas
