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 class 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 dos. Diel period predicts alterations in category size in the two largest organizations. (a) Level of acoustically marked whales thought at the core receivers improve rather for hours on end happn for those for the a few premier communities (red and you may blue, figure step 1).

(c,d) Cam level derived minimal group proportions change from day to night to have a couple of people gray reef whales in this area 2. (On line type in along with.)

(c) Individual-depending patterns

All of our first IBMs revealed that anyone only using information that is personal to help you to acquire resources (loners) has reduced exercise than others using personal and private pointers (electronic secondary material, S5). Less than every simulated scenarios off undertaking rates off target quality (productive award) and you can plot density, the latest proportion off ‘loner’ some body quickly rejected usually so you’re able to extinction, until productive rewards have been quite high (digital additional matter, S5). All of our 2nd a number of activities (individual and public facts/particular CPFs, anyone else wanderers) revealed that despite target high quality, plot thickness or perhaps the undertaking ratio away from wanderers to CPFs, in all model circumstances CPFs got far greater success moments (shape step 3, electronic supplementary topic, S3 and S5). When simulations was run with quicker foreseeable spatial balances of victim patches, CPFs always had expanded survival moments than simply wandering foragers irrespective of plot occurrence otherwise top quality (shape 3c–f). But not, the real difference into the survival time is actually best from the highest patch densities and you will high quality (profile step 3, electronic additional situation, S3 and you will S5).
