19-day starvation experiments show Antarctic krill digestive gland lipids fell from 21% to 9% dry weight. The data, from the Australian Antarctic Data Centre and last updated in 1995, measures lipid class and fatty acid changes in Euphausia superba to model energy flow in the Antarctic food web.
Use Cases
- Modeling energy flow in Antarctic marine ecosystems based on krill lipid composition changes.
- Assessing krill nutritional condition in the field based on relative levels of polar lipids, free fatty acids, and cholesterol.
- Quantifying dietary input from phytoplankton species based on sterol profiles in krill digestive glands.
- Studying the physiological response of krill to starvation based on detailed lipid class and fatty acid measurements.
Strengths
- Contains specific quantitative measurements, such as lipid percentages and microgram amounts with standard deviations.
- Data is derived from controlled experiments, including a 19-day starvation period and different diet treatments.
- Description explicitly links biomarker levels to field applications for assessing nutritional condition and diet.
Limitations
- Last updated 1995-03-31 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.
