Summary
Mediterranean corals live in habitats with naturally high fluctuations of temperature and salinity, which could enable their survival under future extreme climatic scenarios. The nutritional status of corals is linked to the uptake of several micronutrients, which support cellular metabolism and growth. Among these, iron is a fundamental micronutrient for respiratory and photosynthetic processes. Although the iron concentration in seawater can be extremely low, Mediterranean coastal waters are subject to large quantities of nutrients, including iron, via runoff discharge from land. Most corals require a certain amount of iron to support their metabolic processes, but the assimilation rate, critical thresholds, and the allocation of iron in different spatial compartments of corals remain to be studied. This project aims to describe the effects of elevated temperature and iron enrichment on the microenvironment and ecophysiology of corals from the Mediterranean Sea through a novel combination of high-resolution microsensing technologies, bioimaging, and nanoscale spectrometry to explore coral metabolism at the microscale level. By measuring their metabolic responses during elevated temperature and iron availability, I will quantify the role of inorganic iron for coral cellular metabolism, develop a new coral health index for coral metabolic performance, and share this knowledge openly to target specific actions for stakeholders (e.g., government departments, environmental agencies, scientists). With this valuable fellowship, I aim to expand my scientific experience to assess coral health comprehensively at the microscale, which I strongly believe will be a novel way to observe and predict changes in the natural environment. The outcome will serve as a new tool to precisely understand the extent of environmental changes, in particular, the effects of ocean warming and iron concentration, predicting the consequences on the Mediterranean Sea in the short and long term.
