Physiological and survival data of intertidal mollusks from contrasting upwelling environments

This dataset contains physiological measurements and survival records for two intertidal mollusk species (Chiton granosus and Scurria zebrina) collected from two contrasting coastal upwelling environments in central Chile (semi-permanent and seasonal). Data include capture–recapture records for survival estimation, metabolic rate and heart rate measurements obtained through laboratory assays, and calcification rate estimates based on buoyant weight. Sampling was conducted in situ and complemented with controlled laboratory experiments to assess physiological responses to natural environmental variability. Results indicate variation in metabolism linked to upwelling regimes, with higher survival in semi-permanent upwelling environments. These findings provide insights into phenotypic plasticity and adaptation in marine invertebrates under changing coastal conditions, offering valuable data for future ecological and conservation research.
