Fig. 1: Assessment of coral heat tolerance traits using acute stress experiments.
From: Heat tolerance varies considerably within a reef-building coral species on the Great Barrier Reef
A Experimental design and heat tolerance trait data collection for Acropora hyacinthus colonies across the Great Barrier Reef. B Colonies were sampled from 17 sites to be fragmented to allow 3 replicate fragments in each of 4 temperature treatments in experimental aquaria. C Aquaria were controlled to follow ramp-hold temperature profiles. Photochemical efficiency and chlorophyll content were measured after the ramp down from temperature (dashed lines). D Trait values at temperature treatments were used to calculate retained performance and fit log-logistic curves to generate ED50 values.
