A TSR*TOD tensor interaction significantly influenced path tortuosity ( R ? , Table 3), with linear swimming ( R ? ? 0.7–0.8) following release (Contour 8A), consistent with an offshore transit (Figures 8B,C), preceding a transition (?12–24 h post-release) to daytime tortuous behavior ( R ? ? 0.3–0.4, Figure 8A). A subsequent reduction in tortuosity beyond ?45 h post-release was exhibited by the shark with the longer deployment (Figure 8A). These results corroborated findings from HMMs. Pseudo-tracks indicated highly tortuous periods were characterized by extended durations (lasting from 20 min to 4.7 h continuously) where sharks swam in circles, alternating between clockwise and counterclockwise rotations (individual circles completed in ?1–2 min, Figures 8D,E and Supplementary Figure 6). Nonetheless, we note that because conventional GAMM analysis predicts a smooth continuum of responses (Figure 8A), this was less objective for identifying patterns in circling behavior specifically, compared to HMMs that explicitly ics in circling (state 5) from those of other movement states (e.g., meandering, state 4; Figure 7). R ? was positively related to DR (estimated df = 4.24, F = , p < 0.001, Figure 9A), with tortuous swimming/circling occurring during level swimming at the seabed or surface, and linear swimming occurring more with diving (Figures 9B,C). We also noted instances where sharks remained approximately stationary whilst circling northward into a southward-flowing current in offshore waters (Supplementary Video 3).
Dining table step three. Coefficients and dependence on smooth terminology having period (TOD), big date once the release (TSR), as well as their tensor correspondence of a beneficial beta generalized additive combined model forecasting imply resulting length.
(A) Response body proving predicted viewpoints to own suggest resulting size ( Roentgen ? ) centered on a serious tensor easy communication of your time off go out (TOD) and you may day as discharge (TSR) off a beta general additive blended design. Supposed variance (highway tortuosity) reduces while the R ? grows of 0 (tortuous diving) to a single (linear diving). Circumstances let you know the latest distribution away from predictor viewpoints (TOD and TSR) for everyone private whales across the response body. (B) One hour pseudo-tune and (C) corresponding turning direction study (calculated during the 1 s menstruation), illustrating linear diving into the middle throughout the day eventually (?1 h) after launch. (D) Two-hour pseudo-track and you can (E) associated turning position analysis showing highly tortuous, clockwise, and you may counterclockwise circular diving decisions within the middle throughout the day, ?24 h just after discharge. Brand new flipping perspective colour legend is actually uniform across the all turning angle and you may pseudo-tune plots. X- and you will Y-axes is scaled similarly getting pseudo-songs. A 100 yards level club emerges to suggest the new approximate cousin level of movement, of course a predetermined diving rates (0.82 m s –step 1 ) for each shark.
Figure nine. (A) Predict matchmaking (grey shading = 95% depend on times) between dive proportion (DR, proportion of your time invested plunge/inside the says 1 or 2) and imply resulting duration ( R ? , step one = lowest supposed variance, 0 = higher heading difference) out-of a great beta generalized additive combined design. DR and Roentgen ? was basically determined over fifteen minute windows for each and every shark. Plunge users and you will related pseudo-tune areas over associated windowed periods (black rectangles) to own whales (B) s291w and you will (C) s330w indicating user samples of linear swimming through the intensive dive attacks and you may tortuous passion, together with circling behavior, throughout the height phase in the seabed and surface. This new depth colour size is actually consistent one of all the plots of land. Having pseudo-tracks, x- (pseudo-longitude) and you will Y-axes (pseudo-latitude) is scaled similarly, and north is into the top for every single spot. A great 2 hundred meters scale pub is additionally conveyed on each pseudo-song to point the brand new calculate relative spatial level of motion, and when a predetermined diving speed (0.82 meters s –step 1 ) for everybody whales.
