The regional effects of climate change on the demographic connectivity of parrotfish in nine MPAs in the South Atlantic were evaluated through the regionalization of the HadGEM2-ES terrestrial system model, in the scenario of climate projections RCP 8.5, for the end of the 21st century. The results anticipate a warmer tropical ocean, and changes in surface currents, potentially influencing the survival of marine organisms and the connectivity of marine protected areas (MPAs) networks. High mortality rates will reduce demographic connectivity and increase isolation between oceanic islands. Simulation of the organism's response to ocean warming shows that acclimatization can significantly improve larval survival, promoting connectivity and tropicalization of MPAs, with potential impacts on their functional integrity and long-term resilience.
