Lorena is an M.Sc. student studying the reproductive ecology of the invasive sea urchin species Diadema setosum in the Mediterranean Sea. Originally from the Red Sea, this species has now expanded all along the coasts of the eastern Mediterranean, yet little is known about its reproductive cycle or ecology in its new environment. Her research aims to fill this knowledge gap by investigating the reproductive cycle of D. setosum in the Mediterranean, providing insights into its potential for further spread, ecological impact, and valuable information for decision-makers on how to best manage and control these populations.
