About the research project
This PhD will aim to quantify mineralisation of the exoskeleton of juvenile tropical as a function of endogenous (stored) and exogeneous (food and environment) mineral sources. Mineral fluxes in crustaceans around moulting signifies specific physiological adaptations particularly aimed at maintaining the acid-base homeostasis. At the pre-moult stage, minerals are resorbed from the old cuticle and at post-moult stage, the new cuticle is mineralised. Crustacea have some specific mechanisms to store resorbed minerals, particularly calcium from the old cuticle and which is made available to mineralise the new cuticle at post-moult. However, this endogenous source of mineral is not considered significant in marine crustacea due to it being readily available in the environment. Therefore, it is generally accepted that food and the environment are the main source for minerals in marine crustacea and the relative importance of these two sources are species dependent. At present, the ability for juvenile tropical to store and reutilise resorbed minerals is unknown. Similarly, the relative contributions of minerals from food and the environment is as well unknown. A quantitative assessment of the three potential mineral sources (stored, food and environment) which makes up the exoskeleton is key to feed formulation. The PhD will employ a wide range of analytical tools to further understanding of the mechanism by which the acid-base balance in juvenile tropical is maintained.
The successful applicant will receive a scholarship which provides:
- a living allowance stipend of $28,597 per annum (2021 rate, indexed annually) for 3.5 years
