Thermal Tolerance of Mutagen-Treated Coral Symbionts from 2021-2022 Experiments

Reciprocal transplant experiments assessed the thermal adaptation of three Symbiodiniaceae strains after 4.6-5 years of experimental evolution. Measurements of growth, photochemical efficiency, oxidative stress, and nutrient use were collected at the AIMS Symbiont Culture Facility between October 2021 and May 2022. The dataset contains results for heat-evolved and wild-type strains under ambient and elevated temperature treatments.

Use Cases

• Modeling thermal tolerance evolution in coral symbionts based on long-term experimental selection data.
• Analyzing trade-offs between growth and stress response based on photochemical efficiency and oxidative stress measurements.
• Comparing nutrient use efficiency between mutagen-treated and wild-type algal strains under different temperature regimes.
• Training predictive models for coral bleaching resilience based on in vitro symbiont performance data.

Strengths

• Data collection spans a defined 7-month period from 01.10.2021 to 01.05.2022.
• Experiments involve three distinct Symbiodiniaceae species (Durusdinium trenchii, Fugacium kawagutii, Symbiodinium pilosum).
• Includes measurements for four key physiological traits: growth, photochemical efficiency, oxidative stress, and nutrient use.
• Compares heat-evolved strains after 4.6-5 years of selection with wild-type controls.

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 experimental bias inherent to controlled in vitro culture conditions.
