Three gastropod species endemic to the subantarctic Macquarie Island were exposed to five concentrations of copper in controlled seawater tests. Experiments were conducted both on the island and at the Australian Antarctic Division in Tasmania between the 2013/14 austral summer and 2015. The description details precise collection habitats, laboratory acclimation periods, and strict water quality controls for the toxicity tests.
Use Cases
- Modeling species-specific copper toxicity thresholds based on controlled exposure experiments.
- Assessing habitat-specific vulnerability to pollution based on the described intertidal and subtidal collection zones.
- Comparing laboratory-based toxicity results with field conditions from the described stable sea temperature range of ~4-7°C.
- Studying acclimation effects on toxicity based on the described 2-day vs. 2-month pre-test housing periods.
Strengths
- Data collection is described with specific environmental parameters: dissolved oxygen >80%, salinity 33 35 ppt, pH 8.1 8.3.
- Experimental controls are detailed, including acid-washed glassware, filtered seawater, and verified metal-free baseline samples.
- Study covers three distinct gastropod species from varied habitats within the intertidal and subtidal zones.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
