not, there is no evidence for diversity centered on sex ( r d w (SE): Y1: ?0

Controlling for spatial preferences, the mixture model retrieved a total of 972 significant social clustering events (Y1 = 209; Y2 = 227; Y3 = 277; Y4 = 259). Calculating a weighted assortativity coefficient for each annual network revealed significant social assortment by spatial community membership ( r d w : Y1 = 0.204; Y2 = 0.129; Y3 = 0.176; Y4 = 0.130) when tested against a null model of 10 000 random networks (figure 1c). 074 (0.065), Y2: 0.129 (0.015), Y3: 0.177 (0.025), Y4: ?0.043 (0.042)). Mantel tests revealed that there was a strong correlation in the dyadic association strength between pairs for years 12 (n = 29, Mantel r = 0.74, CI = 0.13–0.30, p < 0.001), 23 (n = 35, Mantel r = 0.85, CI = 0.13–0.29, p < 0.001), 34 (n = 31, Mantel r = 0.78, CI = 0.13–0.27, p < 0.001) and finally for the duration of the study for years 14 (n = 22, Mantel r = 0.76, CI = 0.16–0.35, p < 0.001).

(b) Alterations in group size

The number of tagged sharks increased throughout the morning, for both communities (blue and red), peaking about (GLMM R 2 = 0.18, 0.10; F = 244.9, 111.9, p < 0.001, community 2, community 4, respectively; figure 2a). The number of tagged sharks detected then decreased, reaching a minimum by – before starting to increase at – (figure 2a). Footage from camera tags deployed on two sharks showed that group size typically varied between two and 14 individuals, with group size increasing throughout the morning and peaking in the afternoon (figure 2c, electronic supplementary material, video S4). Close following behaviour, where individuals were approximately less than 1 m from a conspecific, was commonly observed (electronic supplementary material, S4). It is likely that detection range of receivers will be reduced at night due to increased noise on the reef, which may influence our ability to detect individuals. However, the more gradual increase in shark numbers throughout the early morning as well camera footage still suggests diel changes in group size are genuine.

Figure 2. Diel months forecasts changes in group size within the a few largest groups. (a) Amount of acoustically tagged whales observed from the core receivers raise rather all day for people inside the one or two prominent teams (purple and you will bluish, figure step one). (b) Physique need regarding a pet-borne camera of a gray reef shark entering personal following conduct. (c,d) Digital camera level derived lowest group proportions changes all day long to possess a few women grey reef whales contained in this community dos. (On line adaptation inside along with.)

(c) Individual-established patterns

All of our basic IBMs revealed that people only using private information so you can to find tips (loners) keeps much lower exercise compared to those having fun with societal and private recommendations (electronic additional thing, S5). Under all the artificial issues of creating ratios out-of guardian soulmates support sufferer quality (effective prize) and you can spot density, the new ratio of ‘loner’ people rapidly denied typically so you’re able to extinction, unless of course energetic benefits have been quite high (electronic secondary material, S5). All of our 2nd series of activities (individual and you can public info/specific CPFs, other people wanderers) showed that no matter target top quality, area occurrence or perhaps the carrying out ratio off wanderers to CPFs, in most modeling scenarios CPFs got far higher success moments (profile step 3, electronic second question, S3 and you will S5). Whenever simulations was indeed work with with faster predictable spatial stability off target spots, CPFs always had prolonged endurance moments than simply drifting foragers no matter spot thickness or quality (contour 3c–f). not, the difference into the survival time try most readily useful in the highest area densities and you may high quality (shape step three, electronic second topic, S3 and you may S5).
