Thermal Tolerance of Giant Kelp Sporophytes from 49 Family Lines

A common garden experiment tested the thermal tolerance of 49 unique family lines of microscopic giant kelp (Macrocystis pyrifera) sporophytes under four water temperatures (12, 16, 20, and 24°C). The family lines were F1 offspring from selfed individuals and crosses collected from six sites across approximately 250 km in Tasmania, Australia. The dataset is associated with the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling intraspecific variation in thermal tolerance based on family-line and temperature treatment data.
• Identifying warm-adapted kelp genotypes for potential use in restoration projects based on survivorship trials.
• Studying the genetic basis of climate resilience in marine macroalgae based on controlled experimental data.

Strengths

• Data is derived from a controlled common garden experiment with four distinct temperature treatments.
• Includes 49 unique family lines, providing a basis for assessing intraspecific genetic variation.
• Samples represent a geographic spread across ~250 km in Tasmania, capturing potential local adaptation.

Limitations

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