Mean waveforms throughout the experiments.

<p>Top panel: comparison of the first consensus waveforms drawn for rhythmic crabs at 13.5°C. Lower panel: comparison of the consensus waveforms drawn for rhythmic crabs at 17.5°C. Data are replotted from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0175403#pone.0175403.g001" target="_blank">Fig 1</a>. Each point represents mean ± SEM.</p

Individual actograms at 17°C and 13°C.

<p>Individual double-plotted actograms at 17°C (A) and 13°C (B) for 3 representative crabs for each experiment, kept first under a 12:12 LD cycle (10 and 8 days respectively) and then transferred to LL conditions (12 days for both). To the right of each actogram, periodograms display the period of the oscillation that significantly (<i>p</i> ≤ 0.05) explains most of the variance in the analysis, indicated in minutes. For each actogram, there are two periodograms corresponding to the activity under LD and LL, respectively. Crabs were collected in summer and tested in free-running either at 13 or 17°C. Crabs depicted under 13°C are not the same individuals depicted under 17°C.</p
