Data from a study exploring the influence of ionic composition on ostracod species in south-eastern Australian saline lakes. Occurrences are reported as physiologically important ionic ratios set in a marine-meteoric framework, with chemical boundaries determined by mixing and evaporation models. The dataset likely contains records linking ostracod presence to specific geochemical pathways and activity ratios.
Use Cases
- Modeling species distribution based on ionic ratios like Na+/H+ and Na+/Ca2+.
- Identifying chemical boundaries for halophilous ostracods using alkalinity/Cl- activity ratios.
- Investigating the influence of halite recycling and solute evolution pathways on aquatic organism communities.
Strengths
- Data is grounded in the Eugster-Jones-Hardie models of solute evolution, providing a theoretical framework.
- Links biological occurrences to specific, physiologically important ionic ratios (e.g., alkalinity/Cl- ~ -2.3).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated metadata shows a future date (2026-05-05).
