Overview of thesis

Ocean Warming alongside increasingly intense marine heatwaves threaten marine species and ecosystems. Temperate seagrass species are already experiencing substantial losses and decline due to significant seawater temperature increases. While warming is known to affect plant physiology and survival, its effects on the reproductive processes that sustain seagrass populations remain predominantly unknown. Clément PhD work will investigate the effect of temperature upon seagrass reproduction and it linked influences on flowering, fruit production and seedling recruitment across a natural latitudinal thermal gradient from Shark Bay to the Great Southern Region. Clement aims to combined multiple distinctive techniques and its application from different timescales. Some of his works will aims to historically reconstruct flowering events in past Posidonia australis meadows, phenological tracking from flowering induction to mature fruiting developments, and use of translocation from specific sed sourcing meadows. The outcome of this field-based data will be to improved predictions of the timing, duration and reproductive capacity of P. australis across its Western Australian range, grounded in empirical thermal tolerance data and long-term historical records of flowering performance. And how current restoration practices, can be enhanced restoration practice through the integration of population-specific seedlings thermal tolerance data into future distributional models of Posidonia australis.
