Marine heatwave conditions drive carryover effects in a temperate sponge microbiome and developmental performance

Marine heatwaves are increasingly subjecting organisms to unprecedented stressful conditions, but the biological consequences of these events are still poorly understood. Here we experimentally tested the presence of carryover effects of heatwave conditions on the larval microbiome, settlers' growth rate and metamorphosis duration of the temperate sponge Crella incrustans.
