A two-week aquarium experiment exposed three tropical seagrass species to four pCO2 levels (440, 700, 890, 1204 µatm) to test effects of ocean acidification. Photosynthetic rates, respiration, leaf growth, and chlorophyll content were measured for Cymodocea serrulata, Halodule uninervis, and Thalassia hemprichii collected from the Great Barrier Reef in 2013. The dataset likely contains physiological parameters like Pmax, alpha, Ek, Ec, net productivity, and relative growth rates.
Use Cases
- Modeling seagrass productivity under future CO2 scenarios based on measured photosynthetic parameters.
- Comparing interspecies resilience to acidification based on growth rate and photosynthetic response data.
- Analyzing the relationship between pCO2 levels and non-structural carbohydrate content in seagrass leaves.
- Calibrating ecosystem models with species-specific physiological data from controlled experiments.
Strengths
- Includes data for three distinct tropical seagrass species, allowing for comparative analysis.
- Employs a controlled experimental design with four pCO2 treatments and four replicate aquaria.
- Measures multiple physiological responses: photosynthesis, respiration, growth rates, and chlorophyll content.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is from a short-term (two-week) experiment; long-term ecological effects are not captured.
