Climate change has increased the frequency and intensity of weather-related disasters such as hurricanes and floods. In 2017, Puerto Rico suffered its worst natural disaster, Hurricane Maria, leaving 3,000 dead and provoking a mental health crisis. Cayo Santiago Island, home to a population of rhesus macaques (Macaca mulatta), was devastated by this storm. Testard et al. compared social networks of two groups of macaques before and after the hurricane and found an increase in affiliative social connections, driven largely by monkeys most socially isolated before Hurricane Maria. Further analysis revealed monkeys invested in building new relationships rather than strengthening existing ones. Supported by ORIP (P40OD012217), NIA, and NIMH.
