ResumenABSTRACT Anthropogenic climate change has caused unprecedented declines across a number of marine taxa. Coral reef ecosystems, which are formed by scleractinian corals, face widespread declines in ecosystem health and function due to co‐occurring environmental stressors. Frequent exposure of corals to a variety of biotic and abiotic stressors makes these cnidarians a prime candidate for investigating the effects of multiple stressors on marine ecosystems. In recent decades, hyperthermic bleaching events and disease outbreaks have been prominent stressors on reefs. Disease outbreaks often follow hyperthermic bleaching events, yet the mechanisms driving the sequential associations between bleaching and disease are poorly understood. Here we investigated the mechanisms linking sequential bleaching and disease using the model cnidarian Exaiptasia diaphana . We examined the transcriptomic responses of anemones to immune challenge during immediate recovery from prior heat stress. We observed notable upregulation of apoptotic pathways and downregulation of autophagic pathways in previously heat‐stressed anemones. Furthermore, network analyses suggest that energetic demands associated with recovery from heat stress may support Symbiodiniaceae population recovery at the cost of immune responses, contributing to observed pathogen susceptibility following heat stress. These results provide insight regarding the cellular mechanisms facilitating increased disease susceptibility during recovery from heat stress, highlighting the roles of immunological regulation and nutrient availability in these processes.es_ES
