Variation in Size and Growth of the Great Scallop Pecten maximus along a Latitudinal Gradient
Understanding the relationship between growth and temperature will aid in the evaluation of thermal stress and threats to ectotherms in the context of anticipated climate changes. Most Pecten maximus scallops living at high latitudes in the northern hemisphere have a larger maximum body size than in...
