NESP TWQ 3.1.5 project data from AIMS and JCU shows the effects of ten herbicides on the growth rates and photosynthetic efficiency of the microalgae Rhodomonas salina. Laboratory experiments were conducted from 2018 to 2019, measuring cell density and effective quantum yield. The dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Modeling dose-response relationships for herbicides based on growth rate inhibition data.
- Comparing toxicity of Photosystem II and alternative herbicides on a non-target algal species.
- Calibrating bioassay protocols for microalgae ecotoxicology studies based on the described methods.
Strengths
- Experiments measured two distinct endpoints: growth rates over 72 hours and photosynthetic efficiency after 24 hours.
- Tested ten specific herbicides (e.g., diuron, metribuzin) based on detection in the Great Barrier Reef catchment.
- Laboratory conditions were tightly controlled, including temperature (26 ± 1°C), salinity (35 psu), and light cycles.
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 data_gov_au, focusing on Great Barrier Reef contaminants.
