Thermal Acclimation Gene Expression in Two Antarctic Fish Species

SCIOPS conducted an experiment on Trematomus bernacchii and Pagothenia borchgrevinki to understand thermal acclimation. Fish were exposed to temperatures between environmental baseline and 6°C for 0-28 days, with tissues harvested for genetic expression analysis. The dataset was last updated on NASA's EarthData platform in December 2007.

Use Cases

• Modeling gene expression changes in response to thermal stress based on temperature exposure duration.
• Analyzing shifts in lipid metabolism pathways under different acclimation temperatures.
• Comparing thermal tolerance mechanisms between two Antarctic fish species.
• Investigating membrane function gene regulation in cold-adapted organisms.

Strengths

• Experimental design includes specific temperature treatments (2.5°C, 4°C, 6°C) and exposure durations (0-28 days).
• Focus on genetic expression related to specific biological processes: lipid metabolism and membrane function.

Limitations

• Last updated 2007-12-12 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
