ResumenClimate change, along with other anthropogenic pressures (e.g. water pollution, overfishing and habitat degradation), is severely impacting oceans around the world, producing important changes in its physical and biological structure, and causing marine biodiversity to decline. In this context, the enhancement of conservation and management strategies that mitigate such stressors (e.g. Marine Protected Areas, MPAs) is urgent. In this thesis, we studied the population genetics and ecological responses to warming of the Mediterranean red gorgonian Paramuricea clavata (Risso 1826), in order to contribute to the design of more effective conservation and management measures for this and other similar species. P. clavata is a long-lived, slow-growing, low dispersal and highly vulnerable habitat-forming organism from the coralligenous assemblages. During the last decades, it has been severely impacted by mass mortality events (MME) caused by climate change-related thermal anomalies. P. clavata is essential to maintain biodiversity as it forms habitat for other organisms and it greatly contributes to habitat\'s biomass and complexity. Although the inclusion of habitat formers in the design of MPAs is fundamental to improve the effectiveness of biodiversity protection, these organisms have been generally neglected in the planning of MPAs, which, instead, have been historically designed for the protection of commercially important species.
