An in situ manipulative experiment assessed the impacts of the introduced New Zealand screwshell, Maoricolpus roseus, on native soft-sediment communities in SE Tasmania. The data likely contains measurements of community structure and habitat characteristics under different conditions of screwshell density and state. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-07-22.
Use Cases
- Modeling the relationship between invasive species density and native community structure based on the experimental manipulation described.
- Assessing habitat modification by invasive species based on the described habitat characteristic measurements.
- Comparing the ecological impacts of live versus dead invasive organisms based on the described experimental treatments.
- Studying the role of hermit crabs as secondary occupants of invasive shells based on the mentioned factor.
Strengths
- Data is derived from an in situ manipulative experiment, suggesting controlled field observations.
- Impacts were assessed for multiple factors: high/low density, live/dead shells, and shells with hermit crabs.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the SE Tasmania study site.
