pH sensitivity survival scalar for various taxonomic groups in Puget Sound. A negative survival scalar indicates a negative effect of decreasing pH on survival and a positive scalar indicates a positive effect on survival. The blue points show scalars by class, the orange points are by order, the green points and box plots are by family. Each row of the chart shows the values for taxonomic groups in the given class and the chart is sorted by class level scalars. Classes that calcify are shaded in gray. Outlined classes are primary producers. At each taxonomic level, we applied the method of Busch and McElhany (2016): the scalars were estimated for every taxonomic group in Puget Sound for which we could find matching taxonomy in the literature review database of Busch and McElhany (2016) and for which the total “evidence score” was greater than 1. The evidence score would be less than 1 if their literature contains only a few experimental responses (generally ≤3) that are not of high relevance to survival of species in Puget Sound. The family-level box plot shows the median of the distribution (line), the 25–75% quartiles (box), 1.5 times the interquartile range (Tukey, 1977), and the outliers (black points).
