Ostracod Fauna and Water Chemistry in South-eastern Australian Saline Lakes

South-eastern Australian saline lakes provide data on ostracod species occurrences linked to water ionic composition. The dataset is based on a study exploring the influence of geochemical solute evolution models on species composition. It was published by Geoscience Australia Data and was last updated on 2026-04-30.

Use Cases

• Modeling species distribution based on ionic ratios like Na+/H+ and alkalinity/Cl- mentioned in the description
• Analyzing the biological impact of geochemical pathways (Eugster-Jones-Hardie models) on faunal composition
• Correlating halite recycling processes with the presence of halophilous ostracods
• Studying acid-base and ion regulation tolerances in aquatic organisms across a marine-meteoric framework

Strengths

• Data is grounded in a specific geochemical framework (Eugster-Jones-Hardie models) for solute evolution
• Links biological occurrences to physiologically important ionic ratios and chemical boundaries
• Findings are suggested to be relevant to other aquatic organisms like zooplankton and diatoms

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
