The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals. Thermal plasticity is independent of environmental history in an intertidal seaweed. However, PSII performance between genotypes was similar, suggesting that thermal sensitivity is related to processes other than photosynthesis. Turner, D. 1807-1808 '1808'.

Understanding responses of marine algae to changing ocean temperatures requires knowledge of the impacts of elevated temperatures and the likelihood of adaptation to thermal stress. Furthermore, genetic correlations between embryos grown in the two temperatures were positive, indicating that those genotypes that performed well in elevated temperature also performed well in control temperature.
