Changes in fish community structure.

<p><b>A</b>. Taxonomic structure based on species abundance before and after the regime shift (species are ordered according to their mean abundance before the shift). The species pictured correspond to the first and last decile of the distribution of absolute changes in abundance before and after the shift. Results of permutation tests for change in each species abundance before and after 1998 accounting for multiple testing: ***: <i>p</i> < 0.001; **: 0.001< <i>p</i> <0.01; *: 0.01< <i>p</i> <0.05. <b>B</b>. Percent abundance variation between the two periods. For a given species <i>i</i>, the percentage is computed as follows: (N<i>i</i>_{after 1997} –N<i>i</i>_{before 1997}) ×100/ N<i>i</i>_{before 1997,} with N<i>i</i> the average abundance of species <i>i</i>. <b>C</b>. Evolution of mean body length in fish community. Line types are as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129883#pone.0129883.g001" target="_blank">Fig 1C to 1E</a>. <b>D</b>. Boxplot representing thermal preferendum of negatively and positively impacted species.
