RRAP_ECT2.1: Coral Heat Tolerance Across Life Stages and Crosses (2020-2022)

Reef Restoration and Adaptation Program experiments on three coral species assessed survival, growth, and photosynthetic efficiency under heat stress. Data covers adult, larval, and juvenile life stages from intra-region and inter-region crosses along a Great Barrier Reef thermal gradient. Experiments ran from November 2020 to April 2022, investigating the potential of selective breeding for enhanced thermal resilience.

Use Cases

• Modeling coral survival probability based on parent genetic background and cross type
• Analyzing the persistence of larval heat tolerance into juvenile life stages
• Comparing the influence of inoculated heat-tolerant symbionts versus parent genetics on fitness traits
• Investigating species-specific variation in heat tolerance enhancement from assisted gene flow

Strengths

• Data spans multiple coral life stages (adults, larvae, juveniles) and three species (Acropora kenti, A. tersa, Goniastrea retiformis)
• Experiments were conducted over a defined 17-month period from November 2020 to April 2022
• Includes measurements across multiple phenotypic traits: survival, growth, colour change, and photosystem II quantum yield

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 the Great Barrier Reef study area
