| Sumario: | [eng] Marine ecosystems are increasingly shaped by the combined effects of climate change and human activities, driving shifts in species distributions, ecosystem structure, and habitat suitability. Understanding how these pressures interact at regional scales is essential, as region-specific environmental conditions and ecological strategies can modulate species’ responses to global change. This Ph.D. thesis ex- plores how different dimensions of global change influence the habitat availability and distribution of marine vertebrates, focusing on pelagic fish, pinnipeds, and marine turtles, through three case studies set in the Mediterranean Sea, the Antarctic Peninsula, and the Canary Current Upwelling System. Using diverse modeling approaches, it examines how traits such as foraging behavior and physiological limitations shape species’ capacity to cope with environmental variability and long-term changes driven by global change. In one case study, the spatial overlap between suitable habitats and fishing effort is also assessed, providing insights into areas where human pressures and climate-related impacts may accumulate. Overall, the findings demonstrate the importance of integrating ecological, oceanographic, and human factors into marine management and contribute to a broader understanding of global change impacts on marine vertebrates. |
