Towards better management and conservation of octopus
Determining the metabolic rates and thermal histories of octopus through isotopic proxies.
For this study, PhD student Erica Durante, examined whether chemical markers (isotopes) could be used to record metabolic rate and temperature exposure in octopus. Erica did this by raising octopus in tanks and analysing carbon and oxygen isotopes within the carbonate earstones of octopus. Such proxies could increase our monitoring capabilities for octopus and contribute to their conservation and effective management.
A Definitive Guide to Ageing Octopus
We developed a step-by-step guide to ageing octopus to make practical hands-on knowledge accessible and support the sustainable management of octopus globally. This was a collaborative project with the NSW Department of Primary Industries and was funded by the FRDC.

Celebrating a Successful PhD Journey
In 2024, PhD student, Erica Durante, successfully defended her thesis, marking the completion of her PhD after three years of research.
Erica‘s research focused on cephalopods and using their hard parts to unravel cephalopod ecology.
Congratulations Dr. Erica!

Understanding the impact of climate change on octopus physiology
Using a quantitative proteomics approach, PhD student, Qiaz Hua, investigated the effects of thermal stress on octopus embryos.
Her findings demonstrate changes in vision, protein chaperoning, redox regulation and energy metabolism indicating the severity of the thermal impacts on the early life stages of octopuses.
This research would not have been possible without generous support from the Australian Academy of Science’s Thomas Davies Research Grant.
