After graduating Sahira landed a job as Research Scientist with the Department of Biodiversity, Conservation and Attractions, and is now continuing her work on the Great Southern Reef in the Ngari Capes marine park
Regime shifts and tropicalisation of temperate reefs (PhD 2021)
In marine environments, there is increasing evidence that climate-mediated marine heatwaves and range shifting tropical herbivores can have profound impacts on temperate kelp forests. My project aims to determine the relative importance of marine heatwaves and tropical herbivores in driving persistent change and the degradation of kelp forests on the Great Southern Reef – one of Australia’s most productive and globally unique ecosystems.
