Changes in the fish fauna of western North America correlated with changes in ocean temperature
Many lines of evidence support the conclusion that temperature is a factor of prime importance in the distribution of marine fishes along the Pacific Coast of North America. The correlation between water temperature and the type of fish found is so definite that I feGl justified in drawing inferences, from the known data of fish distribution, regarding ocean temperatures of the past and regarding the temperatures of regions for which the physical data are inadequate....
