MY SHORT SUMMARY FOLLOWS:
The Chilean oyster lives in coastal areas in the middle to high latitudes of southern Chile. The authors report that "the highest mean value of scope for growth [(a measurement of the energy available for growth and reproduction)] was found for the 20°C and the high pCO2 treatment." That was the WARMIST temperature, and HIGHEST CO2 value, studied, suggesting the Chilean oyster has a bright future with oceans getting less alkaline and global warming.
Six environmental treatments were examined for the two predictor variables, three temperatures (10°C, 15°C or 20°C) and two pCO2 concentrations (~400 µatm or ~1000 µatm), for a period of 60 days.
