Predicting the effects of climate change on ecosystems starts in the lab. But are we emulating real-world conditions well? In this new study, we found that heat stress experiments on corals rarely match the conditions of real-world marine heatwaves. (1/2) www.sciencedirect.com/science/arti...

The initial objective was to use available experimental data to test for hormesis (low doses of heat stress are beneficial, but high dose are harmful). It proved hard to evaluate, because lab "heatwaves" were too hot and too short, more akin to heat shock than real heatwaves. (2/2)
