Assisted evolution of corals and their symbionts enhances recruit heat tolerance but with

Experimental data from a 2022 study on the Great Barrier Reef testing assisted evolution interventions for coral heat tolerance. The research involved selective breeding of Acropora spathulata corals based on parental heat tolerance and inoculation of recruits with experimentally evolved symbionts. Data likely contains performance metrics from rapid heat stress assays comparing different offspring groups and symbiont strains.

Use Cases

• Modeling the heritability of heat tolerance in corals based on selective breeding groups (RR, MM, SS, Bulk)
• Comparing the efficacy of heat-evolved (HE) versus wildtype (WT) Symbiodiniaceae symbionts for enhancing coral recruit survival
• Assessing the predictive power of Fv/Fm ED50 phenotyping from rapid heat stress assays for ecologically relevant thermal stress outcomes

Strengths

• Data is derived from controlled experiments at the National SeaSimulator facility, suggesting a structured methodology
• Includes comparisons across multiple intervention types (selective breeding and symbiont inoculation) and parental tolerance percentiles
• Experimental design uses ecologically relevant levels of thermal stress for assessment

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to samples from Davies and Moore Reefs on the Great Barrier Reef
