Fig. 1: Experimental Design.

a Experimental timeline showing pre-exposure treatments, field deployment and stress testing, overlaid on ambient temperatures. b Five day pre-exposure treatments including a control treatment at ambient temperature and four elevated profiles with different characteristics. c Experimental Degree Heating Weeks during pre-exposure treatments. Note that even controls accumulated ~1DHW due to the ambient conditions (reference a). d Rate of change during pre-exposure treatments, calculated as °C/hr, averaged across replicate tanks. Treatment colors are maintained across figures. Source data are provided as a Source Data file.
