Fluoride concentrations up to 5477 micrograms per gram were measured in the exoskeleton of Euphausia crystallorophias, while copepods exhibited whole-body levels as low as 0.87 micrograms per gram. This dataset contains measurements from a range of Antarctic crustaceans, examining relationships between fluoride content, species, lifestyle, and moulting cycles. The data was produced by the Australian Antarctic Data Centre as part of ASAC projects 41 and 587, with metadata last updated in February 1993.
Use Cases
- Analyze fluoride concentration by species, comparing Euphausiids, copepods, amphipods, and mysids.
- Investigate fluoride distribution across body parts, such as exoskeleton, head carapace, abdomen, feeding basket, pleopods, and eyes.
- Model the relationship between moulting cycles and whole-body fluoride content, which peaks 6 days post-ecdysis.
- Study the effect of environmental fluoride additions (6 and 10 micrograms per litre) on moult and whole-animal fluoride concentrations.
- Compare fluoride levels between benthic and pelagic lifestyles across different crustacean species.
Strengths
- Includes measurements from a range of Antarctic crustacean species and habitats.
- Reports specific fluoride concentrations, such as 5477 micrograms per gram in Euphausia crystallorophias exoskeleton and nearly 13,000 micrograms per gram in E. superba mouthparts.
- Contains experimental data on moult cycles and environmental fluoride exposure.
Limitations
- Specific row count, column names, and sample size are unknown.
- Data is from 1993 and may not reflect current environmental conditions.
- Metadata indicates fluoride loss from specimens after long-term storage in formalin, potentially affecting some measurements.
