With increasing certainty and severity of AE, living and death assemblages from estuaries diverge in (Upper) taxonomic similarity and (Lower) among coarse-mesh data sets composed largely of adult specimens, rank-order agreement in species abundance. Solid line connects mean values for each AE score with 95% confidence intervals on the standard error; dotted line connects mean values of fine-mesh data sets (≤ 1 mm; no confidence intervals marked); dashed line connects mean values of 24 identically processed coarse-mesh data sets from the Gulf of Mexico (1.5 mm; AE scores 0, 1 and 2). See SI Text for counterpart plot of shelf data sets.
