Ostracod Occurrences in South-eastern Australian Saline Lakes with Geochemical Ratios

Ostracod species occurrence data from saline lakes in south-eastern Australia, linked to geochemical ionic ratios. The dataset is hosted by Geoscience Australia Data and was last updated on 2026-04-20. It explores how solute evolution pathways influence species composition and provides evidence relevant to other aquatic organisms.

Use Cases

• Modeling ostracod species distribution based on ionic ratios like Na+/H+ and alkalinity/Cl-.
• Analyzing the biological impact of geochemical solute evolution pathways described by Eugster-Jones-Hardie models.
• Investigating the ecological threshold corresponding to an alkalinity/Cl- activity ratio of ~-2.3.
• Studying the habitat preference of halophilous organisms in waters enriched by halite recycling.

Strengths

• Data is framed within established geochemical models (Eugster-Jones-Hardie) for solute evolution.
• Links biological occurrences to specific, physiologically important ionic activity ratios.
• 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.
• Data freshness should be verified despite the 2026-04-20 update timestamp.
