Ardmucknish Bay, Scotland, hosts data from a 125-day experiment monitoring mussels and scallops near a controlled CO2 release. The study analyzes gene transcription for carbonic anhydrases and sodium-potassium ATPases to assess molecular physiological impacts. Replicate individuals were sampled at six time points spanning a 37-day injection and recovery phase.
Use Cases
- Analyze transcription levels of carbonic anhydrase (CAx) genes over six time points to track physiological response to elevated pCO2.
- Compare expression of sodium-potassium ATPase (ATP1A) genes between CO2 release and reference sites for evidence of ion regulatory stress.
- Contrast gene regulation patterns in Mytilus edulis and Pecten maximus species to assess differential tolerance to CO2 exposure.
- Model temporal changes in gene expression across the 37-day injection phase to identify potential acute stress markers.
Strengths
- Data originates from a controlled 125-day field experiment with a defined 37-day CO2 injection phase.
- Includes replicate biological samples from both a treatment and a reference site within the same bay.
- Molecular physiology focus provides specific metrics on gene transcription for key regulatory proteins.
Limitations
- Sample size is limited to caged bivalves at two sites, restricting ecological generalization.
- Findings show no significant gene regulation impact, limiting utility for predictive modeling of severe stress responses.
- Data scope is restricted to two surface-dwelling bivalve species, excluding infaunal organisms and broader ecosystem effects.
