Southern Ocean Calcifier Vulnerability Meta-Analysis

A 2021 meta-analysis synthesizes research on the vulnerability of Southern Ocean marine calcifiers to ocean acidification. The study projects a 0.3 pH decline by 2100 and correlates biological response variation with skeletal mineralogy. It combines a literature review with quantitative analysis of species traits and environmental factors.

Use Cases

• Model species vulnerability by correlating biological responses like shell state and growth rate with skeletal mineralogy categories such as aragonite and high-Mg calcite.
• Assess geographic risk by analyzing species' geographic range data against projected carbonate chemistry alterations in the Southern Ocean.
• Identify resilient taxa by comparing the projected impacts on calcitic, aragonitic, and high-Mg calcite species versus low-Mg calcite species.
• Investigate the interaction of ocean warming and biological traits as factors exacerbating or mitigating ocean acidification effects.

Strengths

• Quantitative meta-analysis methodology synthesizes multiple experimental studies on biological responses.
• Focuses on the Southern Ocean, a region projected to be severely affected by a ~0.3 pH decline by 2100.
• Analysis incorporates specific biological and mineralogical variables like skeletal mineralogy, geographic range, and species traits.

Limitations

• Dataset is a synthesized review article; original experimental data rows and columns are not provided.
• Temporal coverage is based on published studies up to 2021; may not include the most recent experimental findings.
• Geographic scope is limited to the Southern Ocean, reducing generalizability to other marine ecosystems.
