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., , # **Physiological and Survival Data of Intertidal Mollusks from Contrasting Upwelling Environments**

## **Description of the Data and File Structure**

This dataset was generated from a multi-year field and laboratory study assessing the influence of contrasting upwelling systems on the physiology, morphology, and survival of two intertidal mollusk species in central-northern Chile.

* **Field data:** Monthly capture–mark–recapture surveys over 26 months at two sites (semi-permanent vs. seasonal upwelling), environmental variables, and individual morphological traits.
* **Laboratory experiments:** Conducted under controlled conditions to measure metabolic rate and heart rate.
* **Survival analysis:** Estimated using Cormack–Jolly–Seber models within a Bayesian framework.
* **Physiological & morphological analysis:** Linear mixed models.
* **Environmental context:** Satellite sea surface temperature (SST) data from ERA5 were used to charact...,
