Experiments conducted in 2014 measured the response of seagrass photosystems to herbicides. The dataset was created to develop and validate a miniature toxicity assay using isolated seagrass leaves in 12-well plates. It was contributed by the Australian Ocean Data Network.
Use Cases
- Calibrating fluorescence-based toxicity assays based on the described pulse amplitude modulation (PAM) fluorometry methods.
- Modeling dose-response relationships for PSII herbicides based on the described 4-parameter logistic model fitting.
- Comparing phytotoxicity between isolated plant tissues and intact organisms based on the validation experiments mentioned.
- Assessing the influence of light levels on photosynthetic damage based on the experiments conducted at four irradiance conditions.
Strengths
- Experimental protocol is described in detail, including the use of a 4-parameter logistic model for dose-response curves.
- Data validates a specific miniature 12-well plate assay method against intact plant controls.
- Study assesses the influence of multiple light levels on phytotoxicity endpoints.
Limitations
- Row count and dataset scale are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
