Application of the Presence AMBI and AMBI to outfall monitoring data from 1972 to 1995 at Los Angeles County Station 6C (2.2 km from the outfall) and Station 0C (14.7 km from the outfall).

<p>Application of the Presence AMBI and AMBI to outfall monitoring data from 1972 to 1995 at Los Angeles County Station 6C (2.2 km from the outfall) and Station 0C (14.7 km from the outfall).</p

Pearson correlation coefficients (r) between benthic indices and measures of pollution at Los Angeles County Stations 6C and 0C from 1972 to 1995.

<p>Organic nitrogen is a measure of eutrophication and the mean ERM <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040875#pone.0040875-Long1" target="_blank">[17]</a> quotient is a measure of sediment contamination. For each of eight measured metals, the ERM quotient measures the ratio of the observed concentration to the value at which biological effects are likely, and the mean ERM quotient for the eight metals is an integrated measure of the likelihood of contaminant effects.</p

Barcoding success rates.

<p>The percentages of species yielding COI sequences of more than 500 base pairs are presented.</p

Effect of reductions in numbers of taxa on the AZTI Marine Biotic Index (AMBI).

Percentages of taxa with BRI tolerance scores which have CO1 sequences available in the Barcode Of Life Database.

<p>Taxa were segregated into six categories along the disturbance gradient by BRI tolerance scores. The total number of taxa with tolerance scores in each category are presented above the bar indicating sequence availability. Barcodes were available for 163 of 462 taxa with tolerance scores.</p

Application of the Presence AMBI and AMBI to 1990 seasonal outfall monitoring data at Orange County Station 0 (adjacent to the outfall) and Station Con (8 km from the outfall).

Sediment metal and organic nitrogen concentrations from 1972 to 1995 at Los Angeles County Stations 6C and 0C, for which benthic index data are presented in <b>Figures 3</b> and <b>4</b>.

<p>For each sample, concentrations of eight metals are integrated as mean effects range median (ERM, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040875#pone.0040875-Long1" target="_blank">[17]</a>) quotients. For each metal, the ERM quotient measures the ratio of the observed concentration to the value at which biological effects are likely, and the mean ERM quotient for the eight metals is an integrated measure of the likelihood of contaminant effects.</p
