Jessica Guerchon
I鈥檓 a marine biologist with a BSc and MSc in marine biology and hands-on experience in research, teaching, and fieldwork. I鈥檝e always been drawn to ocean life and the way biology, behaviour, and the physical environment interact. I moved to Australia to undertake a PhD at 91色情片 because I wanted to work at the intersection of marine ecology, real-world coastal issues, and strong research infrastructure. Outside of work, I鈥檓 happiest in the water or outdoors, and I love diving and running.

Project Title:聽Understanding Physalia spp. Behaviour, Reproduction, Morphology and Population Dynamics, for Ecological Insight and Management Applications
Project Description:聽Bluebottles (Physalia spp.) are a common and highly visible marine organism around Australia, with major impacts on beach safety and coastal management due to painful stings and frequent mass strandings. My PhD aims to understand how different bluebottle lineages are distributed and connected around Australia, how they respond to environmental conditions, and how this relates to where and when they arrive on beaches. I鈥檓 building a nationwide citizen science DNA sampling network to map population connectivity and seasonal patterns, alongside controlled behavioural trials that test responses to wind, UV, and temperature under experimental conditions. I also document and compare their morphology between Physalia utriculus and Physalia megalista, to quantify variation within and between lineages and support reliable identification across regions and seasons. The results will improve interpretation of stranding events, strengthen understanding of bluebottle population connectivity and morphology, and support future forecasting and management strategies.
