Research examines the physiological effects of CO2-acidified seawater and warming on embryos and larvae of the Antarctic sea urchin Sterechinus neumayeri. The study, supported by AMD_USAPDC, uses metrics like morphometrics and gene expression profiling to assess development and biomineralization changes. Data was last updated in July 2014.
Use Cases
- Analyze larval endoskeleton changes using morphometric data under high-CO2 conditions.
- Profile gene expression data for biomineralization genes from DNA microarray experiments.
- Assess development rates and physiological costs for embryos and larvae across acidification treatments.
- Model synergistic effects by combining CO2-acidification and ocean warming stressor data.
Strengths
- Focuses on a key Antarctic calcifier considered a 'first responder' to ocean acidification.
- Investigates multiple physiological metrics: development, morphometrics, gene expression, and costs.
Limitations
- Dataset recency is unclear, with last update recorded in 2014.
- Specific sample sizes, row counts, and column details are not provided.
