The genus extirpation concentration distribution (XCD) for fish. The genus extirpation concentrations at the 95th percentile (XC95) values (open circles) for fish genera observed ≥ 25 times are plotted along with the species XC95 value (small solid circles) for fish species observed ≥ 25 times, although some species are obscured by plotting at the same location. For visualization, the horizontal lines connect fish species in the same genus. The 5th percentile of the cumulative distribution of XC95 (XCD05) is the specific conductivity (SC) (545 μS/cm) at the intercept of the genus XCD with the horizontal gray dashed line at the 5th percentile. The black circles represent species or genera where the calculated XC95 values are either not qualified or qualified as “approximately,” and the gray circles are species or genera for which the calculated XC95 values are qualified as “greater than.” The genus XCD is truncated to allow the names to be listed for the first 35 genera.
