Fig. 3From: The sponge holobiont in a changing ocean: from microbes to ecosystemsConceptual representation of holobiont health and the potential outcomes upon environmental stress. Health is regarded as a dynamic equilibrium balanced by the host, the microbiome, as well as the interaction between them. Understanding the underlying principles of health and holobiont dynamics would help predict the responses upon perturbation and whether the final outcome will allow stability, yield disease, or turn into an opportunity for adaptationBack to article page
