Testing for heat tolerance
Parental colonies are tested for heat tolerant phenotypes through temperature stress experiments so that offspring phenotypic lineage is known. Offspring are tested for their heat tolerance at different life stages (larvae, spat, juveniles and adults). By testing heat tolerances of corals with known phenotypic lineages, we can establish how heritable this trait is and use this information to model assisted evolution interventions.
Offspring are kept in a common in situ nursery to reduce differential acclimatisation to environmental conditions.
