Artificial selection of coral larval heat tolerance to support coral restoration (RRAP ECT

A 2023 experiment tested the artificial selection of heat tolerance in Acropora spathulata coral larvae from Davies Reef. The dataset likely contains phenotypic and survival data from larvae exposed to Ambient (27°C), Sub-lethal (33°C), and lethal Selection (35°C) treatments, with subsequent field deployment of 162 seeding devices. The data was aggregated by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling coral larval survival rates based on thermal stress exposure levels.
• Analyzing genetic bottleneck effects from artificial selection protocols.
• Evaluating field performance trade-offs for coral recruits across different reef zones (back reef, lagoon, reef flank).
• Training predictive models for coral restoration outcomes using phenotypic and environmental data.

Strengths

• Data is derived from a controlled experiment with three defined temperature treatments (27°C, 33°C, 35°C).
• Includes field validation from 162 deployed coral seeding devices across three distinct reef sites.
• Specifies the coral species (Acropora spathulata), collection location (Davies Reef), and collection date (October 2023).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
