From: Coupling spectral analysis and hidden Markov models for the segmentation of behavioural patterns
Mean normalized periodogram of each behavioural state for the low-frequency range (6 to 72 h) (a); box-plot of SLPLog-Log values (median is indicated in bold) for each behavioural state (b); and relative occurrence frequencies of the behavioural states at each site (c), discriminated from the fitted five-state HMM. In (a) and (b), results are presented for all sites and individuals pooled together. CB: Cap Breton, DK: Dunkirk, LT: La Turballe, SQ: Saint-Quay
