How does heat stress affect sponge microbiomes? Structure and resilience of microbial communities of marine sponges from different habitats
Introduction Sponges are key components of marine benthic communities, providing many ecosystem functions and establishing close relationships with microorganisms, conforming the holobiont. These symbiotic microbiotas seem to be host species-specific and highly diverse, playing key roles in their sp...
