Australian Ocean Data Network hosts a dataset examining interactions between native hermit crabs and the introduced New Zealand screwshell (Maoricolpus roseus) in eastern Tasmania. The work investigates variation in shell occupancy across depths of 10, 20, 30, and 40 meters at Dennes Point and includes sediment core analysis and preference trials. The dataset was last updated on 2026-07-13.
Use Cases
- Analyze depth-related variance in shell occupancy by hermit crabs based on sampling at 10, 20, 30, and 40 meters.
- Compare sediment size structure between 10m and 20m depths based on collected sediment cores.
- Investigate sediment preference of the hermit crab Paguristes tuberculatus using trial data from 10m and 20m sediments.
Strengths
- Data collection covers four distinct depth levels (10, 20, 30, and 40 meters) for comparative analysis.
- Includes experimental data from a sediment preference trial for the species Paguristes tuberculatus.
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 as the last update is dated 2026-07-13.
